Les mondes virtuels sont issus des MMORPG, Massively Multiplayer Online Role-Playing Games qui sont eux-mêmes issus du monde du jeu vidéo. À ce titre, il existe une filiation « ludique » entre ces différents dispositifs. Les travaux de Steinkuehler suggèrent que les mécanismes de l’apprentissage générés par les jeux issus des mondes virtuels dépendent « certes de la nature du jeu mais aussi des pratiques sociales qu’ils engendrent ». Dans cette continuité, nous avons démontré dans nos travaux que ces environnements (...) immersifs permettaient de créer du lien social et donnaient lieu à des formes de rites numériques entre sphère privée et publique. Dans cet article nous nous intéressons aux controverses des environnements immer- sifs en questionnant la place du corps virtuel au sein de ces dispositifs qui pourraient se situer selon nous, entre lieux de spectacle, de loisir et d’apprentissage médiatisé. Le cas des serious games sera évoqué à titre d’illustration.Virtual worlds started with the MMORPG who emerged from the video gaming world, thus indicating their play-related origins. Steinkuehler’s work suggests that the learning mechanisms triggered by games in the virtual world depend “on the nature of the game obviously, but also on the social practices they give rise to”. Continuing this line of study, our work shows that these immersive environments actually forge social ties and generate digital rites of various kinds between the public and private spheres. In this article, we explore the controversies around immersive environments through an investigation of the virtual body within these systems, which we believe function as venues partly for entertainment, partly for leisure and partly as mediated learning spaces. The case of “serious games” is discussed here as an illustration. (shrink)

To offer engaging neurorehabilitation training to neurologic patients, motor tasks are often visualized in virtual reality. Recently introduced head-mounted displays allow to realistically mimic the body of the user from a first-person perspective in a highly immersive VR environment. In this immersive environment, users may embody avatars with different body characteristics. Importantly, body characteristics impact how people perform actions. Therefore, alternating body perceptions using immersive VR may be a powerful tool to promote motor activity in neurologic (...) patients. However, the ability of the brain to adapt motor commands based on a perceived modified reality has not yet been fully explored. To fill this gap, we “tricked the brain” using immersive VR and investigated if multisensory feedback modulating the physical properties of an embodied avatar influences motor brain networks and control. Ten healthy participants were immersed in a virtual environment using an HMD, where they saw an avatar from first-person perspective. We slowly transformed the surface of the avatar from human to stone. We enforced this visual change by repetitively touching the real arm of the participant and the arm of the avatar with a hammer, while progressively replacing the sound of the hammer against skin with stone hitting sound via loudspeaker. We applied single-pulse transcranial magnetic simulation to evaluate changes in motor cortical excitability associated with the illusion. Further, to investigate if the “stone illusion” affected motor control, participants performed a reaching task with the human and stone avatar. Questionnaires assessed the subjectively reported strength of embodiment and illusion. Our results show that participants experienced the “stone arm illusion.” Particularly, they rated their arm as heavier, colder, stiffer, and more insensitive when immersed with the stone than human avatar, without the illusion affecting their experienced feeling of body ownership. Further, the reported illusion strength was associated with enhanced motor cortical excitability and faster movement initiations, indicating that participants may have physically mirrored and compensated for the embodied body characteristics of the stone avatar. Together, immersive VR has the potential to influence motor brain networks by subtly modifying the perception of reality, opening new perspectives for the motor recovery of patients. (shrink)

Conversation is a time-pressured environment. Recognizing a social action (the ‘‘speech act,’’ such as a question requesting information) early is crucial in conversation to quickly understand the intended message and plan a timely response. Fast turns between interlocutors are especially relevant for responses to questions since a long gap may be meaningful by itself. Human language is multimodal, involving speech as well as visual signals from the body, including the face. But little is known about how conversational facial signals (...) contribute to the communication of social actions. Some of the most prominent facial signals in conversation are eyebrow movements. Previous studies found links between eyebrow movements and questions, suggesting that these facial signals could contribute to the rapid recognition of questions. Therefore, we aimed to investigate whether early eyebrow movements (eyebrow frown or raise vs. no eyebrow movement) facilitate question identification. Participants were instructed to view videos of avatars where the presence of eyebrow movements accompanying questions was manipulated. Their task was to indicate whether the utterance was a question or a statement as accurately and quickly as possible. Data were collected using the online testing platform Gorilla. Results showed higher accuracies and faster response times for questions with eyebrow frowns, suggesting a facilitative role of eyebrow frowns for question identification. This means that facial signals can critically contribute to the communication of social actions in conversation by signaling social action-specific visual information and providing visual cues to speakers’ intentions.

Extended reality devices provide users with unprecedented immersive and hybrid perceptual experiences, and users will act their bodies according to the information perceived. This shows that visual perception plays a crucial role in the formation and shaping of self-perception and spatial position. Users have a strong perceptual experience of their physical presence and self-perception in the real world as a result of their avatar perspective based on visual perception in a virtual hybrid environment, as is issued by Chalmers (...) in his "Mirror Argument". However, users can still clearly differentiate their self and spatial experience between virtual and reality. To refute Chalmers' argument regarding perceptual experience in virtual reality, this article proposes a thought experiment called "Mary's Room in the Virtual Reality World" based on the experimental evidence of neuroscience. Finally, a possible future solution to this dilemma is presented. (shrink)

By contrast to the competitive and participatory models of sport, the immersive model shows greater potentiality as a healthful practice more distant from transcendent, technocratic aspects of other models, instead accepting the body's immanence as part of evolutionary history and the natural world. Because of the largely unconscious, evolutionarily based responses to one's environment, the environment in which a sporting activity takes place has a tangible impact on performance. As our most evolutionarily recent sense system, visuality is linked to (...) the Social Engagement System. The mediated experience of sport through visual culture might catalyse the Social Engagement System and the perception that the sporting activity is communal and welcoming. Particularly the subculture surrounding the sport of CrossFit, which spread almost entirely through website presence and the posting of videos of workouts on the mainsite, might be said to exemplify how growth in new sports is augmented by visuality and the formation of virtual communities that then become embodied.

Previous research using immersive virtual reality (VR) has shown that after a short period of embodiment of White people in a Black virtual body their implicit racial bias against Black people diminishes. Here we tested the effects of some socio-cognitive variables that could contribute to enhancing or reducing the implicit racial bias. The first aim of the study was to assess the beneficial effects of cooperation within a VR scenario, the second aim was to provide preliminary testing (...) of the hypothesis that empathy and political attitudes could contribute to implicit bias about race, while the third aim was to explore the relationship between political attitudes and empathy. We had (Caucasian) participants embodied in a Black virtual body and engaged either in a cooperative (Coop group) or in a non-cooperative (Neutral group) activity with a confederate experimenter embodying another Black avatar. Before and after VR, we measured participants’ implicit racial bias by means of Implicit Association Test (IAT) and their perceived closeness toward the confederate experimenter. Before VR we also assessed participants’ political attitudes and empathy traits. Results revealed that, as compared to the Neutral group, the Coop group showed lower IAT scores after the social interaction. Interestingly, in the Neutral but not the Coop group the perceived closeness toward the confederate experimenter was associated with the initial racial bias: the more the participants reduced their distance, the more they reduced their IAT score. Moreover, reported traits of empathy and political attitudes significantly explained the variance observed in the initial implicit bias, with perspective-taking, empathic concern, and personal distress being significant predictors of the IAT scores. Finally, there was a relationship between political attitudes and empathy: the more participants considered themselves as left-wing voters, the higher their perspective-taking and empathic concern scores. We discuss these findings within the neuroscientific and social cognition field and encourage scholars from different domains to further explore whether and under which conditions a given manipulation for reducing racial bias could be efficiently transposed in VR.

This article considers two related and fundamental issues about morality in a virtual world. The first is whether the anonymity that is a feature of virtual worlds can shed light upon whether people are moral when they can act with impunity. The second issue is whether there are any moral obligations in a virtual world and if so what they might be. -/- Our reasons for being good are fundamental to understanding what it is that makes us (...) moral or indeed whether any of us truly are moral. Plato grapples with this problem in book two of The Republic where Socrates is challenged by his brothers Adeimantus and Glaucon. They argue that people are moral only because of the costs to them of being immoral; the external constraints of morality. -/- Glaucon asks us to imagine a magical ring that enables its wearers to become invisible and capable of acting anonymously. The ring is in some respects analogous to the possibilities created by online virtual worlds such as Second Life, so the dialogue is our entry point into considering morality within these worlds. These worlds are three dimensional user created environments where people control avatars and live virtual lives. As well as being an important social phenomenon, virtual worlds and what people chose to do in them can shed light on what people will do when they can act without fear of normal sanction. -/- This paper begins by explaining the traditional challenge to morality posed by Plato, relating this to conduct in virtual worlds. Then the paper will consider the following skeptical objection. A precondition of all moral requirements is the ability to act. There are no moral requirements in virtual worlds because they are virtual and it is impossible to act in a virtual world. Because avatars do not have real bodies and the persons controlling avatars are not truly embodied, it is impossible for people to truly act in a virtual world. We will show that it is possible to perform some actions and suggest a number of moral requirements that might plausibly be thought to result. Because avatars cannot feel physical pain or pleasure these moral requirements are interestingly different from those of real life. Hume’s arguments for why we should be moral apply to virtual worlds and we conclude by considering how this explains why morality exists in these environments. (shrink)

Critics have argued that human-controlled avatar interactions fail to facilitate the kinds of expressivity and social understanding afforded by our physical bodies. We identify three claims meant to justify the supposed expressive limits of avatar interactions compared to our physical interactions. First, “The Limited Expressivity Claim”: avatars have a more limited expressive range than our physical bodies. Second, “The Inputted Expressivity Claim”: any expressive avatarial behaviour must be deliberately inputted by the user. Third, “The Decoding Claim”: users must infer (...) or figure out the expressive meaning of human-controlled avatars’ behaviour through cognitively onerous processes. With the aim of critically assessing all three claims, we analyze data collected through observations of and interviews with expert players of the avatar-based video game League of Legends. Focusing on Daniel Stern’s (2010) notion of vitality, we analyze the participants’ descriptions of seeing and interacting with other avatars during performance. Our analysis shows that the informants experience human-based avatarial interactions as qualitatively different than interactions with bots, that the informants see the movements of other players’ avatars as having different expressive styles, and that the informants actively use and manipulate this avatarial expressivity during performance. The results of our analysis, we argue, provide reasons for loosening or resisting the three claims concerning the limits of avatarial expressivity. (shrink)

The efficient coding hypothesis posits that sensory systems are tuned to the regularities of their natural input. The statistics of natural image databases have been the topic of many studies, which have revealed biases in the distribution of orientations that are related to neural representations as well as behavior in psychophysical tasks. However, commonly used natural image databases contain images taken with a camera with a planar image sensor and limited field of view. Thus, these images do not incorporate the (...) physical properties of the visual system and its active use reflecting body and eye movements. Here, we investigate quantitatively, whether the active use of the visual system influences image statistics across the visual field by simulating visual behaviors in an avatar in a naturalistic virtual environment. Images with a field of view of 120° were generated during exploration of a virtual forest environment both for a human and cat avatar. The physical properties of the visual system were taken into account by projecting the images onto idealized retinas according to models of the eyes' geometrical optics. Crucially, different active gaze behaviors were simulated to obtain image ensembles that allow investigating the consequences of active visual behaviors on the statistics of the input to the visual system. In the central visual field, the statistics of the virtual images matched photographic images regarding their power spectra and a bias in edge orientations toward cardinal directions. At larger eccentricities, the cardinal bias was superimposed with a gradually increasing radial bias. The strength of this effect depends on the active visual behavior and the physical properties of the eye. There were also significant differences between the upper and lower visual field, which became stronger depending on how the environment was actively sampled. Taken together, the results show that quantitatively relating natural image statistics to neural representations and psychophysical behavior requires not only to take the structure of the environment into account, but also the physical properties of the visual system, and its active use in behavior.

This book investigates the ontological state of relations in a unique way. Starting with the notion of system, it shows that the system can be understood as a relational structure, and that relations can be assessed within themselves, with no need to transform relations in elements. “Relations” are understood in contrast to “relational property”: without a relation there is no identity, therefore no existence. What allows us to do that without hypostatizing the relation, and without immediately taking it simply as (...) a causal relation, can be better grasped, possibly, in reference to a few entities that make best display of their systemic nature, for example images, works of art, and virtual bodies. This book shows how virtual bodies are ontological hybrids representing a type of entity that has never appeared in the world before. This entity becomes a phenomenon in interactivity and evades the dichotomy between “external” and “internal”; it is neither a cognitive product of the consciousness, nor an image of the mind. The user is well aware of experiencing anotherreality, also in the sense of a paradoxical reduplication of perceptual synthesis. The virtual body-environment is therefore simultaneously external and internal, with virtual bodies-environments to be seen as artificial windows to an intermediary world. In this intermediary world, the space itself is the result of interactivity; the world takes place in the sense or feeling of immersion experienced by the user; and the body, perceived as “other”, takes upon itself the sense of its reality, of its effectiveness, as an imaginary and pathic incision, as a production of desire and emotion, to the point that the feeling of reality conveyed by a virtual environment will rely significantly on how this environment produces emotions in the users.

Addiction: A Philosophical Approach CHAPTER ABSTRACTS “Introduction: Dismantling the Catchphrase” by Candice Shelby Shelby dismantles the catchphrase “disease of addiction.” The characterization of addiction as a disease permeates both research and treatment, but that understanding fails to get at the complexity involved in human addiction. Shelby introduces another way of thinking about addiction, one that implies that is properly understood neither as a disease nor merely as a choice, or set of choices. Addiction is a phenomenon emergent from a complex (...) dynamic system that is at once physical, psychological, social, and more. “A Philosophical Analysis of Addiction” by Candice Shelby Shelby brings much-needed clarity to the discourse surrounding the topic of addiction. Arguing that addiction can neither properly be understood as a disease nor as merely a set of choices, Shelby exposes the weaknesses of both approaches. She shows that addicted persons do not exhibit the elements characteristic of compulsion, nor does an account of addiction in terms of weakness of will, or irrational choosing, provide a satisfying explanation. Instead, by replacing traditional substance ontology with process ontology, and accepting the reality of emergent entities, a coherent account of persons, minds, and addiction can be provided. A fundamental philosophical shift is necessary to see that bodies, minds, values, and addictions are all part of the natural world. “Addiction at the Individual Level” by Candice Shelby Shelby discusses the most influential accounts of addiction as it is understood at the purely individual level. From hedonic theories to incentive sensitization, to habit theories of addiction, to behavioral theories and the ego depletion theory, Shelby considers a variety of approaches to understanding addiction in individuals, as framed in both psychological and in neuroscientific terms. She notes some important caveats that should be considered before accepting the research regarding addiction at the individual level, namely that the scanning studies that are so popularly used to characterize addiction in neurobiological terms are ambiguous, and rely on numerous assumptions that may be false, and that certainly mislead. Shelby provides much-needed critique of both disease and choices models as they characterize addiction at the individual level. “Addiction and the Local Environment” by Candice Shelby Shelby argues that human addiction cannot be understood without serious consideration of the individual’s local environment, her home and family. From the gestational environment to interactions with caregivers during post-natal development to the adult environment in which people become addicted, Shelby shows that no one becomes an addict in a vacuum. Stress is a major influence in the environment throughout life, and has serious consequences for addictive vulnerability. Genetic influences as well are important to addictive vulnerability, but genes always express in interaction with their environment. Social acceptance or rejection is another particularly important factor in the local environment with respect to both coming to be addicted and transitioning out of it. “The Relation Between Addiction and Culture” by Candice Shelby Shelby provides a groundbreaking analysis of the relation between addicts and the cultures that breed them. In this cultural critique, Shelby shows that addictions to certain substances have historically been both the solution to the problem of how to grow economies and control people, and a problem for economic productivity and controlling citizens. Not all cultures have even the concept of addiction, while others, such as the contemporary Western world, and the U.S. in particular, seem to foster it. Shelby shows that addiction is both a cultural construct and, from another way of thinking about it, the result of conditions created by particular cultures. Social inequities, alienation, driving capitalism, and in particular the power of pharmaceutical companies, all contribute to the spiraling endemic of addiction. “Addiction and Meaning” by Candice Shelby Shelby provides a unique argument that understanding how meanings work is essential to a complete analysis of addiction. Individuals experiencing addiction and those who care about and for them often utterly fail to communicate. This is because their respective systems of meanings come to be significantly different. Meanings are not, Shelby argues, best understood in the symbolic terms that characterized the theory of language in the 20th century, but are better apprehended as emotion-rich prototypes carved from repeated interaction with the world. Becoming addicted essentially changes one’s entire system of meanings. Requisite to transitioning out of addiction is a Gestalt-type shift in one’s system of meanings. This holistic way of understanding meanings also provides one level of explanation of what happens when an addict relapses. “The Phenomenology of Addiction and its Implications” by Candice Shelby One way of judging theories of addiction is by how well they capture the phenomenal descriptions that addicts give of their own experiences. Shelby considers variations on 5 basic patterns of addictive experience through the eyes of particular individuals who lived through addictive periods, and shows how even the most influential theories of addiction fail to capture all of them. She argues that an important implication of taking the details of individuals’ addictive stories seriously is that addiction must be understood as a personal phenomenon emergent from a particular complex dynamic system. As her theory of addiction would lead one to expect, no two addicts are the same, and no single-focus theory can explain why not. “Possibilities for Transitioning Out of Addiction” by Candice Shelby Shelby provides numerous strategies for transitioning out of addiction. Given that the vast majority of addiction treatment programs currently available are 12-step based and only successful about 5-8% of the time, it is essential that other approaches be undertaken. Shelby canvasses a variety of options for helping addicted individuals to make the transition out of their troubled pattern of thinking and behaving. From direct brain interventions to drugs to trauma therapy to exercise and nutrition to habit reformation to use of narrative and changing one’s social context as ways of redefining the self, Shelby shows that the possibilities for transitioning out of addiction are legion. Perhaps the best approach is to understand addiction treatment in terms of providing physical, psychological, and social tool kits. “Addiction Emerges from a Complex Dynamic System” by Candice Shelby Shelby considers whether there truly exists such a thing as “an addict” or “addictive thinking” in the universal sense. She concludes that within the context of disruptive substance use or repetitive engagement in certain activities, ordinary human cognitive biases and behavior patterns are categorized as addictive. Addiction, she argues, is best understood as an irreducible human reality, emergent from a sufficiently complex dynamic system (an organism with self-awareness, within a particular cultural milieu) that is both shaped by and contributes to the shaping of its environment. Attempts to simplify addiction into one or a few dimensions may create a solvable problem, but by doing so they fail to solve the real one. (shrink)

The distinction between the first-person perspective (1PP) and the third-person perspective (3PP) has been widely regarded as fundamental and rigid, and many researchers hold that genuine bodily illusions can only be experienced from the 1PP. We applied VR technology to investigate whether this mainstream view is correct. In our experiments, the participants were immersed in a VR environment in which they saw a life-sized virtual body either from the 1PP or from the 3PP. They either passively received tactile stimulations (...) and/or actively interacted with a virtual soccer ball. Our VR system created novel visuo-motor-tactile correlations between the real and the virtual world: when the participant interacted with a real plastic soccer ball, he/she would feel corresponding tactile sensations and see the avatar performing the exact same movements. We found that a clear sense of ownership over the avatar was induced not only in the 1PP condition but also in the Passive-3PP and the Active-3PP conditions. We also observed evidence suggesting that it is possible to experience one’s body-location, 1PP-location, as well as self-location, both from the 1PP and from the 3PP. Together, we demonstrate that there is in fact no fundamental gap between embodied 1PP and embodied 3PP in the virtual world. (shrink)

Virtual reality enables individuals to be exposed to naturalistic environments in laboratory settings, offering new possibilities for research in human neuroscience and treatment of mental disorders. We used VR to study psychological, autonomic and postural reactions to heights in individuals with varying intensity of fear of heights. Study participants were immersed in a VR of an unprotected open-air elevator platform in an urban area, while standing on an unstable ground. Virtual elevation of the platform elicited robust and (...) reliable psychophysiological activation including increased distress, heart rate, and electrodermal activity, which was higher in individuals suffering from fear of heights. In these individuals, compared with individuals with low fear of heights, the VR height exposure resulted in higher velocity of postural movements as well as decreased low-frequency body sway oscillations. This indicates that individuals with strong fear of heights react to heights with maladaptive rigidity of posture due to increased weight of visual input for balance control, while the visual information is less reliable at heights. Our findings show that exposure to height in a naturalistic VR environment elicits a complex reaction involving correlated changes of the emotional state, autonomic activity, and postural balance, which are exaggerated in individuals with fear of heights.

Today, avatars often represent users in digital worlds such as in video games or workplace applications. Avatars embody the user and perform their actions in these artificial environments. As a result, users sometimes develop the feeling that their self merges with their avatar. The user realizes that they are the avatar, but the avatar is also the user—meaning that avatar’s appearance, character, and actions also affect their self. In the present paper, we first introduce the event-coding approach of the (...) self and then argue based on the reviewed literature on human-avatar interaction that a self-controlled avatar can lead to avatar-self merging: the user sets their own goals in the virtual environment, plans and executes the avatar’s actions, and compares the predicted with the actual motion outcomes of the avatar. This makes the user feel body ownership and agency over the avatar’s action. Following the event-coding account, avatar-self merging should not be seen as an all-or-nothing process, but rather as a continuous process to which various factors contribute, including successfully taking the perspective of the avatar. Against this background, we discuss affective, cognitive, and visuo-spatial perspective taking of the avatar. As evidence for avatar-self merging, we present findings showing that when users take the avatar’s perspective, they can show spontaneous behavioral tendencies that run counter to their own.

Movement abnormalities are prevalent across all stages of schizophrenia contributing to poor social functioning and reduced quality of life. To date, treatments are scarce, often involving pharmacological agents, but none have been shown to improve movement abnormalities effectively. Virtual reality (VR) is a tool used to simulate virtual environments where behavioral performance can be quantified safely across different tasks while exerting control over stimulus delivery, feedback and measurement in real time. Sensory information is transmittedviaa head mounted (...) display allowing users to directly interact with virtual objects and bodies using gestures and body movements in the real world to perform different actions, permitting a sense of immersion in the simulated virtual environment. Although, VR has been widely used for successful motor rehabilitation in a variety of different neurological domains, none have been exploited for motor rehabilitation in schizophrenia. The objectives of this article are to review movement abnormalities specific to schizophrenia, and how VR can be utilized to restore and improve motor functioning in patients with schizophrenia. Constructing VR-mediated motor-cognitive interventions that can help in retaining and transferring the learned outcomes to real life are also discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:If “Reality is the Best Metaphor,” It Must Be VirtualMarguerite R. Waller (bio)What is the search for the next great compelling application but a search for the human identity?—Doug Coupland, Microserfs... we can look forward to a richly textured and complex cyberspace, where we are at all times human, and can become bits of pixel dust flying through a virtual landscape.—3-D, multiuser, interactive, on-line virtual reality producer“Avatars (...) are Next,” the June 1996 issue of Wired announces on its cover, above a glossy foldout of Bill Gates in bathing trunks floating on a lemon yellow air mattress in a sensuous Hockney-blue swimming pool. “Mr. Bill goes Hollywood! Special Gatesfold Issue,” reads the caption underneath the (photomontaged) naked torso. The United States Congress’s attempt in February 1996 to conceptualize the Internet as an incitement to indecent sexual conduct (in Section 507 of the 1996 Telecommunications Act, the so-called Computer Decency Act) is clearly the lampooned subtext of this juxtaposition of sexualized body with the concept of the avatar. The antithesis of sensuous, avatars are bandwidth-conserving, virtual figures that take the place of users’ physical bodies in the three-dimensional, interactive, multiuser virtual environments that software developers in 1996 insist will be the telos of the development of the World Wide Web. The Wired cover implies that the nerd community finds Congress’s association of digital media with sex ridiculous (however flattering they may find it to be constructed as sexually dangerous). Not unusually, sexuality is being invoked by the state as a justification for extending its own reach (and the corporate interests it represents).But the sex/gender politics of Net free speech advocates are not necessarily more progressive. As feminist commentator Laura Miller argues in “Women and Children First: Gender and the Settling of the Electronic Frontier,” the metaphor of a frontier beyond the jurisdiction of Congress, deployed by opponents of federal regulation, draws upon a conventional construction of gender that threatens to reinscribe women as victims, reinforcing “the power imbalance between the sexes, with its roots in the concept of women as property, constantly under siege and requiring the vigilant protection of their male owners” [53]. The unintended consequence of this conceptualization, she worries, is that “the threat of regulation is built into the very mythos used to conceptualize the Net by its defenders” [50].My worry, therefore, embraces both sides of the debate over free speech on the Net. The skirmish between Big Brother and the software pioneers seems to be shaping up rhetorically as a classic fraternal competition “between men” (Sedgwick). We may read it as a contest between fundamentally congruent “male” subject positions, both of which incline to disempower “female” subject positions and both of which stand to increase their [End Page 90] own political and economic capital by the appearance of a conflict. The power-producing relationality at play in this turf war, however, simultaneously threatens to subvert the claims of each position to its own, independent ontology. Both parties, therefore, can be expected compulsively to deny their relational status. John Perry Barlowe insists, in his “Declaration of Independence in Cyberspace”: “Your legal concepts of property, expression, identity, movement, and context do not apply to us. They are based on matter. There is no matter here.”It is this more subtle metaphysical issue, the occlusion of relation, implicated in but not reducible to, the constructions of sexuality and gender deployed by both Netizens and Congresspeople, that I find the most pressing issue in designs, uses, and discussions of cyberspace. I will argue that, in fact, the current wave of Internet development (both practically and discursively) is in some sense driven by a desire to make cyberspace safe for essentialist subjectivities of whatever ideological/political persuasion. I will unfold this argument in terms of a certain notion of addiction. My interest is not “cyberaddiction” per se, in the sense of individuals who spend what they or their associates consider too much time on-line, but rather the construction of cyberspace—both rhetorically and electronically—as a clean, clear realm in which we can transcend positionality while remaining (or becoming more fully) “ourselves.” I am not, that...

Virtual Reality has often been referred to as an “empathy machine.” This is mostly because it can induce empathy through embodiment experiences in outgroup membership. However, the potential of intergroup contact with an outgroup avatar in VR to increase empathy is less studied. Even though intergroup contact literature suggests that less threatening and more prosocial emotions are the key to understanding why intergroup contact is a powerful mean to decrease prejudice, few studies have investigated the effect of intergroup contact (...) on empathy in VR. In this study, we developed a between-participants design to investigate how VR can be used to create a positive intergroup contact with a member of a stigmatized outgroup and present the results of the effect of intergroup contact in VR on empathy. Sixty four participants experienced either positive contact with a black avatar or no intergroup contact, with situational empathy being measured through a self-report questionnaire up to a week before and right after the VR contact experience. The experiment showed that satisfying degrees of body ownership of participants’ own avatar and co-presence with the contacted avatar can be achieved in simple and universally accessible virtual environments such as AltspaceVR. The results indicated that while VR intergroup contact had no significant direct effect on empathy, exploratory analyses indicated that post-intervention empathic interest increased with stronger feelings of co-presence in the intergroup contact condition.

Natural scientists working at the intersection of virtual reality, psychology, and computer science have recently explored the question of whether Embodied Virtual Reality (EVR) can be employed to train empathy. While for some authors (e.g., Bertrand et el. 2018), EVR can enhance empathy by means of creating a series of perceptual illusions, which lead users to adopt the other’s perspective and resonate with her experience, other authors (e.g., Sora-Domenjó 2022; Sutherland 2016) have been more skeptical about the powers (...) of EVR to increase empathy in its users. This chapter aims at contributing to this recent debate by exploring how perspective-taking contributes to empathy in EVR. After an analysis of perspective-taking in non-virtual and virtual environments, the chapter introduces the distinction between sensual and emotional empathy found in classical and contemporary phenomenology (Stein 1989 ; Sveaneus 2018). While in sensual empathy, the user empathizes with the other’s lived body, in emotional empathy, she apprehends the other’s emotional states and their related values. It is argued that while the perceptual illusions elicited by EVR can lead the user to the impression of a body swap and, in so doing, foster sensual empathy, for the apprehension of the other’s emotions, which is crucial to emotional empathy, EVR must be supplemented with a series of narrative devices which that make the other’s emotions and values accessible to her.

We previously showed that the illusory sense of ownership and agency over a moving body in immersive virtual reality can trigger subjective and physiological reactions on the real subject’s body and, therefore, an acute improvement of cognitive functions after a single session of high-intensity intermittent exercise performed exclusively by one’s own virtual body, similar to what happens when we actually do physical activity. As well as confirming previous results, here, we aimed at finding in the elderly an (...) increased improvement after a longer virtual training with similar characteristics. Forty-two healthy older subjects completed a parallel-group randomized controlled trial including an adapted version of the virtual training previously used: while sitting, participants observed the virtual body in a first-person perspective or a third-person perspective performing 20 min of virtual high-intensity intermittent exercise. This was repeated twice a week for 6 weeks. During the vHIE, we measured the heart rate and administered questionnaires to evaluate illusory body ownership and agency. Before the beginning of the intervention, immediately after the first session of vHIE, and at the end of the entire intervention, we evaluated the cognitive performance at the Stroop task with online recording of the hemodynamic activity over the left dorsolateral prefrontal cortex. While we confirm previous results regarding the virtual illusion and its physiological effects, we did not find significant cognitive or neural improvement immediately after the first vHIE session. As a novelty, in the 1PP group only, we detected a significant decrease in the response time of the Stroop task in the post-intervention assessment compared to its baseline; coherently, we found an increased activation on left dorsolateral prefrontal cortex after the entire intervention. While the current results strengthen the impact of the virtual full-body illusion and its physiological consequences on the elderly as well, they might have stronger and more established body representations. Perhaps, a longer and increased exposure to those illusions is necessary to initiate the cascade of events that culminates to an improved cognitive performance. (shrink)

This paper illustrates how external symbol grounding can be studied in simulations with large populations. We discuss how we can simulate language evolution in a relatively complex environment which has been developed in the context of the New Ties project. This project has the objective of evolving a cultural society and, in doing so, the agents have to evolve a communication system that is grounded in their interactions with their virtual environment and with other individuals. A preliminary experiment is (...) presented in which we investigate the effect of a number of learning mechanisms. The results show that the social symbol grounding problem is a particularly hard one; however, we provide an ideal platform to study this problem. (shrink)

In this article, I respond to important questions raised by Gallagher and Jacobson in the field of cognitive science about face-to-face interactions in Heidegger’s account of ‘intersubjectivity’ in Being and Time. They have criticized his account for a lack of attention to primary intersubjectivity, or immediate, face-to-face interactions; he favours, they argue, embodied interactions via objects. I argue that the same assumption underlies their argument as did earlier critiques of a lack of an account of the body in Heidegger ; (...) namely that because the body is not explicitly discussed in Being and Time, embodiment, rather than stressing the immediacy of experience, is insufficiently acknowledged in his emphasis on ‘being-in-the-world’. Through placing Gallagher and Jacobson’s accounts of intersubjectivity and the body alongside Heidegger’s accounts of Mitsein and Leib, this article shows Heidegger’s radical position on the body as immersed in a holistic environment, and its reverberations on his account of intersubjectivity. I argue that Dasein’s embodied engagement in the world is always one of immediacy and that the body of the other is perceived as ‘tied into’ its context, as well. In so doing, I offer an Heideggerian account of ecstatic involvement which moves away from the distinction between primary and secondary intersubjectivity toward an immediate engagement with objects and people always already ‘tied into’ a context; an account that, through the concept of Fürsorge, includes shifts of attention between objects and people that allow for the ethical distinctions Gallagher and Jacobson are looking for.

Every human community creates its own representation of its surrounding world and of the men who constitute that world. It sets out in an orderly fashion the raison d’être of social and cultural organisation, it ritualises the ties between men and their relationship with their environment. Man creates the world while the world creates man, through a relationship which varies with each society; ethnography shows us innumerable versions. Human cultures consist of symbols. It is always a matter of reducing (...) the world to the human factor, but in line with a social imaginary quantity specific to a particular group, which is itself the tributary of its past and the possible influence of other groups.

Con la validación a partir del criterio de especialistas y la sistematización con la introducción en la práctica, se evaluó el mismo como muy adecuado, fue considerado útil, necesario y aplicable al contexto objeto de estudio, lo que contribuye a la formación científica de los estudiantes desde una posición materialista. Science, technology and society studies reveal the interrelations between science and technology as social processes. This article pursues the following objectives: to assess the social significance of a virtual environment in the teaching and learning of descriptive Statistics in Medicine degree course. The preliminary diagnosis through the observation, opinion poll and documentary analysis, showed that there are insufficiencies in the use of Information and Communication technologies in teaching and learning Statistics. It was designed a virtual environment with five modules that include contents of descriptive Statistics, exercises, bibliography and help. With the validation of specialists and the systematization after putting it in practice, the virtual environment was assessed as adequate, useful, necessary and applicable to the context being studied, which contributes to the scientific training of students from a materialistic position.

This article explores four major areas of moral concern regarding virtual reality technologies. First, VR poses potential mental health risks, including Depersonalization/Derealization Disorder. Second, VR technology raises serious concerns related to personal neglect of users’ own actual bodies and real physical environments. Third, VR technologies may be used to record personal data which could be deployed in ways that threaten personal privacy and present a danger related to manipulation of users’ beliefs, emotions, and behaviors. Finally, there are other (...) moral and social risks associated with the way VR blurs the distinction between the real and illusory. These concerns regarding VR naturally raise questions about public policy. The article makes several recommendations for legal regulations of VR that together address each of the above concerns. It is argued that these regulations would not seriously threaten personal liberty but rather would protect and enhance the autonomy of VR consumers. (shrink)

Globalization and informatization are reshaping human life and social behaviors. The purpose is to explore the worldwide strategies to cultivate international talents with a global vision. As a global language with the largest population, English, and especially its learning effect, have always been the major concerns of scholars and educators. This work innovatively studies the combination of immersion-based English teaching with virtual reality technology. Then, based on the experimental design mode, 106 students from a Chinese school were selected (...) for a quasi-experimental study for 16 weeks. The collected data were analyzed by computer statistical software, and hypotheses are verified. The results showed that there is a significantly positive correlation between VR and immersion-based language teaching. There is a significantly positive correlation between immersion-based language teaching and academic achievement, and VR is positively correlated with learning outcome. Compared with other state-of-art research methods, this work modifies the students’ oral test through the analysis and comparison with the system database, and the students’ learning effect is greatly improved. Finally, some suggestions are put forward according to the research results to provide an experimental reference for English teachers and future linguistics teaching. (shrink)

This study investigates the Proteus effect from the first-person perspective and during avatar embodiment in actual exercise. In addition to the immediate measurements of the Proteus effect, prolonged effects such as next-day perception and exercise-related outcomes are also explored. We theorized the Proteus effect as altered perceived self-concept and explored the association between virtual reality avatar manipulation and self-concept in the exercise context. While existing studies have mainly investigated the Proteus effect in a non-VR environment or after VR embodiment, (...) we aim to contribute to the literature by addressing this concern to explore how the Proteus effect works in actual VR exercise. Through a 2 × 2 between-subject experiment, the results partially support the Proteus effect. Regarding actual physical activity, embodying an avatar with a six pack during exercise creates fewer body movements. No significant effect was found for perceived exertion. We also explored the role of sex as a potential moderator in the association of the Proteus effect on exercise outcomes. The Proteus effect was supported by immediate and next-day self-efficacy for core-muscle exercise only among female participants. The between-subject design allowed us to probe how avatar manipulation of muscular body shape with a six pack as opposed to normal body shape influences participants’ self-concept and exercise outcomes, as limited VR studies have employed within-subject comparisons. This also contributes to the literature by providing an upward comparison as opposed to the previous downward comparison regarding body fitness. The overall results supported the Proteus effect in the context of core-muscle exercise when comparing normal and ideal body shape avatars. However, the Proteus effect as an altered self-concept and its effects on self-efficacy for exercise were supported among females but not males. Whereas the female participants who embodied avatars with a six pack associated themselves more with the muscular concept than other people, the male participants who embodied avatars with a six pack perceived themselves as more normal than others. Theoretical and practical implications are discussed. (shrink)

PurposeThe purpose of this paper is to show how both the presentation and limitation of visual choices in massively multiplayer online role‐playing games (MMORPG) avatar creation interfaces tends to exclude or favor different real life social groups.Design/methodology/approachA novel method combining both quantitative and critical analysis of the syntagmatic‐paradigmatic structure of MMORPG avatar creation interfaces is used to inform the findings of this study.FindingsThis study concludes that as cultural interfaces, current fantasy themed MMORPGs remediate socially exclusive values both from fantasy (...) literature and from their own game lore. The socially exclusive values deal largely with extreme and immutable racial and sexual dimorphism.Research limitations/implicationsInterfaces which present users with color palettes and/or smooth slider‐based body modifiers do not lend themselves well to this method of analysis. In addition to this, only a handful of the popular MMORPGs are analyzed within the body of this work.Practical implicationsThis paper demonstrates that MMORPG players and designers need to be more aware about how they are constructing and embedding social values in their worlds. Avatars are critical conduits for online social dynamics and embedding socially exclusive values may transfer negative ideologies from old media to new.Originality/valueThis paper offers one of the earliest critiques of embedded values in avatar creation interfaces of MMORPGs. The paper aims to begin discussion on an overlooked area of now popular media that has not received any critical attention regarding its embedded messages of social inclusiveness or exclusiveness.

GoalThis paper presents an immersive Virtual Reality system to analyze and train Executive Functions of soccer players. EFs are important cognitive functions for athletes. They are a relevant quality that distinguishes amateurs from professionals.MethodThe system is based on immersive technology, hence, the user interacts naturally and experiences a training session in a virtual world. The proposed system has a modular design supporting the extension of various so-called game modes. Game modes combine selected game mechanics with specific (...) simulation content to target particular training aspects. The system architecture decouples selection/parameterization and analysis of training sessions via a coaching app from an Unity3D-based VR simulation core. Monitoring of user performance and progress is recorded by a database that sends the necessary feedback to the coaching app for analysis.ResultsThe system is tested for VR-critical performance criteria to reveal the usefulness of a new interaction paradigm in the cognitive training and analysis of EFs. Subjective ratings for overall usability show that the design as VR application enhances the user experience compared to a traditional desktop app; whereas the new, unfamiliar interaction paradigm does not negatively impact the effort for using the application.ConclusionThe system can provide immersive training of EF in a fully virtual environment, eliminating potential distraction. It further provides an easy-to-use analyzes tool to compare user but also an automatic, adaptive training mode. (shrink)

It is primordial to insist on a continuous education that is open, flexible, and personalized, allowing the individual to update and make his or her knowledge adequate throughout life. The creation of distributed environments for constructivist learning is a challenge. Research in this field is needed for the development of cooperative learning tools able to facilitate and motivate learning. The development of intelligent didactic systems is complex, demanding the support of knowledge coming from different fields. That is why to (...) develop this class of systems a multidisciplinary team is needed, including pedagogues; educational psychologists; specialists in the knowledge domain; and technicians in computer graphics, programming, multimedia, virtual reality, project management, and so forth. Virtual immersion introduces new resources for interindividual communications that deal with reality interpretation. The authors outline the beginning of a long journey on how imagination power can be used for the collective creation of worlds able to improve learning. (shrink)

We live in the digital age where our sense of self and identity has moved beyond the body to encompass hardware and software. Cyborgs, online representations in social media, avatars, and virtual reality extend our notion of what it means to be human. This approachable book looks at the progression of self from the biological to the technological using a multidisciplinary approach. It examines the notion of personhood from philosophical, psychological, neuroscience, robotics, and artificial intelligence perspectives, showing how (...) the interface between bodies, brains, and technology can give rise to new forms of human identity. Jay Friedenberg presents the content in an organized and easy-to-understand fashion to facilitate learning. A gifted researcher, author, and classroom teacher, he is one of the most influential voices in the field of artificial psychology. (shrink)

Body, Soul and Cyberspace explores how recent science-fiction cinema addresses questions about the connections between body and soul, virtuality, and the ways in which we engage with spirituality in the digital age. The book investigates notions of love, life and death, taking an interdisciplinary approach by combining cinematic themes with religious, philosophical and ethical ideas. Magerstädt argues how even the most spectacle-driven mainstream films such as Avatar, The Matrix and Terminator can raise interesting and important questions about the human self (...) and our interaction with the world. Apart from these well-known science fiction epics, her analysis also draws on recent works, such as Inception, The Thirteenth Floor, eXistenZ, Aeon Flux, Total Recall (2012), Transcendence and TRON: Legacy. These films stimulate an engaging discussion on what makes us human, the role memory plays in understanding ourselves, and how virtual realities challenge the moral concepts that govern human relationships.

Objective: Gait adaptation to environmental challenges is fundamental for independent and safe community ambulation. The possibility of precisely studying gait modulation using standardized protocols of gait analysis closely resembling everyday life scenarios is still an unmet need.Methods: We have developed a fully-immersive virtual reality environment where subjects have to adjust their walking pattern to avoid collision with a virtual agent crossing their gait trajectory. We collected kinematic data of 12 healthy young subjects walking in real world and (...) in the VR environment, both with and without the VA perturbation. The VR environment closely resembled the RW scenario of the gait laboratory. To ensure standardization of the obstacle presentation the starting time speed and trajectory of the VA were defined using the kinematics of the participant as detected online during each walking trial.Results: We did not observe kinematic differences between walking in RW and VR/A-, suggesting that our VR environment per se might not induce significant changes in the locomotor pattern. When facing the VA all subjects consistently reduced stride length and velocity while increasing stride duration. Trunk inclination and mediolateral trajectory deviation also facilitated avoidance of the obstacle.Conclusions: This proof-of-concept study shows that our VR/A+ paradigm effectively induced a timely gait modulation in a standardized immersive and realistic scenario. This protocol could be a powerful research tool to study gait modulation and its derangements in relation to aging and clinical conditions. (shrink)

When a chimpanzee stockpiles rocks as weapons or when a frog sends out mating calls, we might easily assume these animals know their own motivations--that they use the same psychological mechanisms that we do. But as Beyond the Brain indicates, this is a dangerous assumption because animals have different evolutionary trajectories, ecological niches, and physical attributes. How do these differences influence animal thinking and behavior? Removing our human-centered spectacles, Louise Barrett investigates the mind and brain and offers an alternative approach (...) for understanding animal and human cognition. Drawing on examples from animal behavior, comparative psychology, robotics, artificial life, developmental psychology, and cognitive science, Barrett provides remarkable new insights into how animals and humans depend on their bodies and environment--not just their brains--to behave intelligently. Barrett begins with an overview of human cognitive adaptations and how these color our views of other species, brains, and minds. Considering when it is worth having a big brain--or indeed having a brain at all--she investigates exactly what brains are good at. Showing that the brain's evolutionary function guides action in the world, she looks at how physical structure contributes to cognitive processes, and she demonstrates how these processes employ materials and resources in specific environments. Arguing that thinking and behavior constitute a property of the whole organism, not just the brain, Beyond the Brain illustrates how the body, brain, and cognition are tied to the wider world.

Sensorimotor learning refers to improvements that occur through practice in the performance of sensory-guided motor behaviors. Leveraging novel technical capabilities of an immersive virtual environment, we probed the component kinematic processes that mediate sensorimotor learning. Twenty naïve subjects performed a simulated marksmanship task modeled after Olympic Trap Shooting standards. We measured movement kinematics and shooting performance as participants practiced 350 trials while receiving trial-by-trial feedback about shooting success. Spatiotemporal analysis of motion tracking elucidated the ballistic and refinement phases (...) of hand movements. We found systematic changes in movement kinematics that accompanied improvements in shot accuracy during training, though reaction and response times did not change over blocks. In particular, we observed longer, slower, and more precise ballistic movements that replaced effort spent on corrections and refinement. Collectively, these results leverage developments in immersive virtual reality technology to quantify and compare the kinematics of movement during early learning of full-body sensorimotor orienting.

Avatars will represent us online, in virtual worlds, and in technologically supported hybrid environments. We and our avatars will stand not in an identity relation but in a proxy relation, an arrangement that is significant not least because our proxies’ actions can be counted as our own. However, this proxy relation between humans and avatars is not well understood and its consequences under-explored. In this paper I explore the relation and its potential ethical consequences.

This paper is going to discuss, what will be called, ‘The Internet of Bodies’. Our physical and virtual worlds are blending and shifting our understanding of three key areas: (1) our identities are diversifying, as they become hyper-enhanced and multi-sensory; (2) our collaborations are co-created, immersive and connected; (3) our innovations are diverse and inclusive. It is proposed that our bodies have finally become the interface.

In lieu of an abstract, here is a brief excerpt of the content:The Contemplative Classroom, or Learning by Heart in the Age of GoogleBarbara NewmanIn his provocative essay “Slow Knowledge,” David Orr outlines the countervailing assumptions of what he calls “the culture of fast knowledge.” Among these are the widely shared, though rarely examined, beliefs that “only that which can be measured is true knowledge; the more knowledge we have, the better; there are no significant distinctions between information and knowledge; (...) and wisdom is an undefinable, hence unimportant category.”1 If all this were true, it would follow that computers are fast overtaking humans as the next intelligent species. Or, to put it differently, the two species have been colluding for some time to produce smarter machines and dumber people, as we humans abdicate more and more of our mental tasks. Moreover, when it comes time to weigh values—to ask not how quickly or efficiently some task can be done, but whether it ought to be done at all—we are strangely disinclined to challenge digital fatalism, which has become the default logic of late capitalism. Whenever a new digital option appears, we assume that if it can be done and someone somewhere is doing it, then it should be done and we ought to do it too. So even the local hardware store has to be on Facebook so customers can “like” it, and the AAR needs a Twitter account to send weekly tweets. We seldom pause to ask questions about means and ends, unintended consequences, or the sheer mindless clutter of our lives—let alone the implications of this or that new app for our descendants down to the seventh generation, or the enlightenment of all sentient beings. Surface obliterates depth; instant stimulation trumps mature reflection; short-term profit overrules the long-range good.Computers themselves are of course morally neutral. Nonetheless, it is useful to recall why contemplation is the antithesis of the fast knowledge they promote. Contemplative practice is grounded in such values as presence, mindfulness, inwardness, and the integration of mind and body. The last point is worth stressing, for all knowledge, even the most spiritual, is embodied; we are still biological beings, not cyborgs. Though contemplatives of the past have often been fierce ascetics, even the most emaciated hermit could scarcely despise the body to the degree that we find in [End Page 3] some contemporary Internet addicts. Consider the following, reported in July 2012 in Newsweek:When the new DSM [Diagnostic and Statistical Manual of Mental Disorders] is released next year, Internet Addiction Disorder will be included for the first time, albeit in an appendix tagged for “further study.” China, Taiwan, and Korea recently accepted the diagnosis, and began treating problematic Web use as a grave national health crisis. In those countries,... the story is sensational front-page news. One young couple neglected its infant to death while nourishing a virtual baby online. A young man fatally bludgeoned his mother for suggesting he log off (and then used her credit card to rack up more hours). At least 10 ultra-Web users, serviced by one-click noodle delivery, have died of blood clots from sitting too long.2Even short of such extremes, numerous studies have linked excessive Internet use in the United States with increased rates of depression, anxiety, suicidal thoughts, and obsessive-compulsive behavior. Teens admit to being exhausted by the constant need to update their Facebook status and answer countless texts, yet they are afraid to log off for fear that some excitement may pass them by. There is even a new acronym, FOMO, for the fear of missing out. If a central aim of contemplative practice is to dismantle and disengage from the “false self,” there is no better tool for constructing false selves than social media. In her book Alone Together, the social psychologist Sherry Turkle quotes a young man who told her, “What I learned in high school was profiles, profiles, profiles, how to make a me.”3 Another student said he maintained four avatars onscreen at all times, along with his email, video games, and—yes—coursework. His “real life,” he said, was “just one more window,... not usually my best one.”4But social... (shrink)

Virtual reality allows the user to be immersed in environments in which they can experience situations and social interactions from different perspectives by means of virtual embodiment. In the context of rehabilitation of violent behaviors, a participant could experience a virtual violent confrontation from different perspectives, including that of the victim and bystanders. This approach and other virtual scenes can be used as a useful tool for the rehabilitation of intimate partner violence perpetrators, through (...) improvement of their empathic skills or for training in non-violent responses. In this perspective, we revise and discuss the use of this tool in a prison environment for the rehabilitation of IPV perpetrators with a particular focus on practical aspects based on our experience.

While social interaction and play in a VR environment are becoming ever more popular, little is known about how social VR games affect users. The purpose of this study was to elucidate the role of several contingent factors in social VR games by modeling the relationships between involvement, well-being, depression, self-esteem, and social connectedness. A conditional process-moderated mediation model of the measured variables was analyzed with 220 pieces of collected data. The result showed that: the direct (...) effect of involvement on well-being was significant, and the index of moderated mediation involving depression, self-esteem, and social connectedness was significant. We conclude that high levels of involvement in social VR games by socially isolated users with low self-esteem can negatively affect their well-being. The findings of this study contribute in several ways to our understanding of the effect of social VR games upon users and provide important practical implications. (shrink)

The social dimension of purchase seems particularly important when it comes to food, since it can contribute to foster “consumers’ embeddedness” in the local food system. The discussion on this topic is growing after the emergence of alternative food networks , which are thought to have potentials to re-connect the different actors of local food systems, and/or to strengthen the existing social ties among them. This study focuses on the evaluation of the degree of sociality in different food (...) shopping environments. The research is focused on the structure and the features of the interactions, with the aim to provide an assessment of the degree of sociality of AFNs compared to other food chain networks. More specifically, a farmers’ market, a greengrocer and a supermarket have been compared. The three shopping environments show remarkable differences: in the supermarket perfunctory interactions are most often observed, unless shoppers already know each other, whereas the farmers’ market environment is likely to foster quite intense relations among strangers; the greengrocer, on the contrary, shows a completely different pattern of relations, typically involving customers who already know each other. Results support the common argument that farmers’ markets may enhance sociality among people, although some interesting relations patterns are observed in the other food stores as well. Issues for further research in the field emerge, which might be useful to improve the understanding of the social dimension of food shopping as well as to more deeply analyse the elements of attractiveness of AFNs.

In this article, an attempt was made to identify the level of community social participation according to age, gender and the structural characteristics of the personal support networks in a population displaced by floods in the Colombian Caribbean. The research was based in a non-experimental methodology with an associative-relational strategy. An intentional non-probabilistic sample of 151 people affected by the winter wave in the south of the Department of Atlántico (Colombia) was selected. In total, the study included 42 males (...) (27.8 %) and 109 females (72.2 %) participants, with an average age of 37.48 (±14, Range 18 - 80) and average relocation time of 21.79 months (± 8.22, Range 5-36). The Arizona Social Support Interview Schedule (ASSIS) and Community Empowerment instruments were responded to with an instrument adapted from the leadership competence factor. The results show lower rates of intermediation in the older population, and the relationship between social participation and gender shows equally cohesive social support networks in men and women. This evidence is discussed to promote psychosocial interventions aimed to increase community engagement and empowerment of people that have experienced non-voluntary mobility processes. (shrink)

New branches of social science primarily engaging the “internet revolution” are appearing alongside mainstream research and journals such as Cyberpsychology, Behavior, and Social Networking are providing social scientists with an outlet of peer-reviewed research. HPS scholars will find new methodologies and the relation of technology to social science of particularly interest. Social scientists are becoming increasingly interested in virtual realities (see Milburn (Spontaneous Generations 2008, 63)) and are declaring time spent “in-game” ethnographic research. William (...) Sims Bainbridge boasts 2300+ hours (approximately 96 days) of ethnographic research into a virtual world he calls “The Warcraft Civilization.” Blizzard Entertainment reported in a December 2008 press release that World of Warcraft (WoW), its extraordinarily successful 2004 massively multiplayer online role-playing game (MMORPG) comprised 11.5 million subscribers worldwide . In order to accommodate player demand, Blizzard uses hundreds of servers, artfully called realms, each running an instance of WoW for subscribers to play on. There are four types of realms: normal or player-versus-environment (PvE) realms, player-versus-player (PvP) realms, role-playing (RP) realms, and role-playing player-versus-player (RP-PvP) realms. The most popular realms are PvE and PvP; players on RP and RP-PvP realms are meant to “live” in WoW and therefore must adhere to role-playing policies such as remaining “in-character” of the avatar they have selected.

The goal of this article is to present a first list of ethical concerns that may arise from research and personal use of virtual reality (VR) and related technology, and to offer concrete recommendations for minimizing those risks. Many of the recommendations call for focused research initiatives. In the first part of the article, we discuss the relevant evidence from psychology that motivates our concerns. In Section “Plasticity in the Human Mind,” we cover some of the main results suggesting (...) that one’s environment can influence one’s psychological states, as well as recent work on inducing illusions of embodiment. Then, in Section “Illusions of Embodiment and Their Lasting Effect,” we go on to discuss recent evidence indicating that immersion in VR can have psychological effects that last after leaving the virtual environment. In the second part of the article, we turn to the risks and recommendations. We begin, in Section “The Research Ethics of VR,” with the research ethics of VR, covering six main topics: the limits of experimental environments, informed consent, clinical risks, dual-use, online research, and a general point about the limitations of a code of conduct for research. Then, in Section “Risks for Individuals and Society,” we turn to the risks of VR for the general public, covering four main topics: long-term immersion, neglect of the social and physical environment, risky content, and privacy. We offer concrete recommendations for each of these 10 topics, summarized in Table 1. (shrink)

Although it has been shown that immersive virtual reality can be used to induce illusions of ownership over a virtual body , information on whether this changes implicit interpersonal attitudes is meager. Here we demonstrate that embodiment of light-skinned participants in a dark-skinned VB significantly reduced implicit racial bias against dark-skinned people, in contrast to embodiment in light-skinned, purple-skinned or with no VB. 60 females participated in this between-groups experiment, with a VB substituting their own, with full-body (...) visuomotor synchrony, reflected also in a virtual mirror. A racial Implicit Association Test was administered at least three days prior to the experiment, and immediately after the IVR exposure. The change from pre- to post-experience IAT scores suggests that the dark-skinned embodied condition decreased implicit racial bias more than the other conditions. Thus, embodiment may change negative interpersonal attitudes and thus represent a powerful tool for exploring such fundamental psychological and societal phenomena. (shrink)

The problem of aesthetic experience in a virtual environment could be reformulated as: what can we learn about aesthetics from the perspective of ‘aesthetic experience in virtual environments’, given the specific nature of such an environment? The discourse goes in circles, because it is always from theories elaborated in the field of the so-called ‘real’ that we develop the difference, but it is a process typically philosophical, that, on the other hand, can make sense only if it (...) can be shown that the virtual is an existent being that has an ontological structure of its own. The ontology of this strange object–event, and of its relationship to space–time, must therefore be addressed: what are the conditions of identity for a virtual body? What are its limits? In what sense does it have borders? Also, its specific temporality and its connection to human and computer memories are arguable dimensions that deserve analysis, as they directly affect an ontology of the virtual body, the difference between the virtual and the possible, and the relationship between the human body and the virtual body. However, the specific character of the virtual is to be an intermediate entity between object and event, between thing and image, so that virtual bodies represent a hybrid, interactive world which can be visualized as synthetic image, an immersive hybrid engaging the corporeality of the user and merging with the virtual body’s image; this hybridization, between the body of the spectator–actor and the virtual space in which it is immersed, is difficult to define with singularity.
