In the philosophy of perception, olfaction is the perennial problem child, presenting a range of difficulties to those seeking to define its proper referents, and its phenomenological content. Here, we argue that many of these difficulties can be resolved by recognizing the object-like representation of odors in the brain, and by postulating that the basic objects of olfaction are best defined by their biological value to the organism, rather than physico-chemical dimensions of stimuli. Building on this organism-centered account, we speculate (...) that the phenomenological space of olfaction is organized into a number of coarse affective dimensions that apply categorically. This organization may be especially useful for coupling sensation to decision-making and instrumental action in a sensory modality where the stimulus space is especially complex and high-dimensional.

This article summarizes a National Institute of Mental Health workshop that was convened to address the ethical and methodological issues that arise when conducting controlled psychosocial interventions research and introduces 6 thoughtful and inspiring papers prepared by workshop participants. These papers, on topics ranging from informed consent to ethnic minority issues, reflect the depth and breadth of expertise represented by the multidisciplinary group of scientists and ethicists present at the meeting. More extensive follow-up, particularly from federal research applications and publications, (...) of how investigators balance the need for strong research design with ethical considerations may help advance the science of psychosocial intervention research.

Antipoverty movements have generated many “little” or “near” basic income guarantee (BIG) proposals. Most theorists discussing BIG posit a full-fledged universal grant that entirely satisfies the core value guiding their theory. Debates are conducted about feasibility, desirability and rival values. This article looks into particular considerations that need to be made when debating a little BIG. If a “status” value, meaning “all or nothing,” is the core value under debate, then a grant falling short of securing this status will need (...) some other justification. If the core value is “scalar,” meaning there can be more or less of it, then a lower grant can be justified if it is an efficient way to add to that value. I offer two reasons that a little BIG can have merit: 1. Organizations will benefit because the grant provides a clear target for citizen action. 2. There are reasons to think that a BIG of whatever size will promote organizational capabilities more efficiently than money coming from an employer, family member or conditional public entitlement.

The taxonomy proposed by Pessoa et al. should be extended to include “pathological” completion phenomena in patients with unilateral brain damage. Patients with visual field defects (hemianopias) may “complete” whole figures, while patients with parietal lobe damage may “complete” partial figures. We argue that the former may be consistent with the brain “filling-in” information, and the latter may be consistent with the brain ignoring the absence of information.

Mechanisms of selective attention exert a powerful influence on visual perception. We examined whether attentional selection is necessary for generation of the vivid colours experienced by individuals with grapheme-colour synaesthesia. Twelve synaesthetes and matched controls viewed rapid serial displays of nonsense characters within which were embedded an oriented grating (T1) and a letter-prime (T2), forming a modified attentional blink (AB) task. At the end of the stream a coloured probe appeared that was either congruent or incongruent with the synaesthetic colour (...) elicited by the letter-prime. When the prime was attended, synaesthetes showed a reliable effect of prime-probe congruency. In contrast, when the prime appeared at 350 ms following T1 (during the AB), the congruency effect was eliminated. Our findings suggest that focused attention is crucial for inducing letters to elicit colours in synaesthesia. © 2009 Elsevier B.V. All rights reserved. (shrink)

To Vallortigara & Rogers's (V&R's) evidence of everyday directional asymmetries in the natural environment of a variety of species, we offer one more example for human beings. It is the bias for holding an infant on the left side, and it illustrates several themes in the target article.

Mechanisms of selective attention are vital for coherent perception and action. Recent advances in cognitive neuroscience have yielded key insights into the relationship between neural mechanisms of attention and eye movements, and the role of frontal and parietal brain regions as sources of attentional control. Here we explore the growing contribution of reversible neurodisruption techniques, including transcranial magnetic stimulation and microelectrode stimulation, to the cognitive neuroscience of spatial attention. These approaches permit unique causal inferences concerning the relationship between neural processes (...) and behaviour, and have revealed fundamental mechanisms of attention in the human and animal brain. We conclude by suggesting that further advances in the neuroscience of attention will be facilitated by the combination of neurodisruption techniques with established neuroimaging methods. (shrink)

A period of exposure to trains of simultaneous but spatially offset auditory and visual stimuli can induce a temporary shift in the perception of sound location. This phenomenon, known as the 'ventriloquist aftereffect', reflects a realignment of auditory and visual spatial representations such that they approach perceptual alignment despite their physical spatial discordance. Such dynamic changes to sensory representations are likely to underlie the brain's ability to accommodate inter-sensory discordance produced by sensory errors (particularly in sound localization) and variability in (...) sensory transduction. It is currently unknown, however, whether these plastic changes induced by adaptation to spatially disparate inputs occurs automatically or whether they are dependent on selectively attending to the visual or auditory stimuli. Here, we demonstrate that robust auditory spatial aftereffects can be induced even in the presence of a competing visual stimulus. Importantly, we found that when attention is directed to the competing stimuli, the pattern of aftereffects is altered. These results indicate that attention can modulate the ventriloquist aftereffect. © 2010 Elsevier B.V. (shrink)

Mechanisms of attention play a crucial role in filtering sensory inputs from the external world, allowing information to be prioritised for goal directed behaviour. To what extent might these same capacity-limited processes influence grapheme-colour synaesthesia, in which letters, numbers or words evoke concurrent experiences of colour? Asking synaesthetes themselves whether attention seems important in their experiences has provided a range of answers. On the one hand, for some synaesthetes, diverting attention can diminish the quality of their synaesthetic colours. On the (...) other, there are suggestions that synaesthetic experiences can themselves alter the manner in which attention is allocated to sensory stimuli in the environment. Here, we review a range of empirical investigations that have examined the role of attention in grapheme-colour synaesthesia. A particular focus of these studies has been the extent to which an inducing stimulus - such as an achromatic letter or digit - must be attended or consciously perceived to trigger a concurrent synaesthetic experience. In most cases, limiting attention or masking inducers tends to reduce or eliminate behavioural evidence of synaesthetic experiences. We also discuss how synaesthesia might improve performance in visual search tasks through post-attentive processes such as grouping, or by facilitating decision-making processes. (shrink)

This study investigates potential differences in attitudes towards corporate social responsibility between Saudis and Muslims from other predominately Islamic countries. We propose that Saudi Arabia’s unique rentier-state welfare and higher education systems account for these distinctions. In evaluating our propositions, we replicate Brammer et al. :229–243, 2007) survey on attitudes towards CSR using a sample of Saudi undergraduate and graduate business students and compare the results against data from subjects in other majority Muslim countries. In addition, this work examines possible (...) differences within the Saudi sample with respect to sex and academic level. Our results indicate that our Saudi subjects maintain higher expectations for corporations’ social responsibility within their supply chain than the Brammer et al.’s sample. In contrast, Muslims in the Brammer et al.’s sample hold higher expectations for corporations in supporting societal development and poverty alleviation in comparison to the Saudi sample. We also find within the Saudi sample that females and subjects at higher academic levels are more inclined to hold corporations responsible for social issues related to CSR than males and subjects in lower academic levels. We examine these findings, explore their implications, and propose areas for future research. (shrink)

This article presents a framework of ethical analysis for anticipatory evaluation of advanced biopreservation technologies and employs the framework illustratively in three domains. The framework features four clusters of general ethical considerations: (1) Producing Benefits, Minimizing Harms, Balancing Benefits, Risk, and Costs; (2) Justice, Fairness, Equity; (3) Respect for Autonomy; and (4) Transparency, Trustworthiness, and Public Trust.

Adaptation to right-shifting prisms improves left neglect for mental number line bisection. This study examined whether adaptation affects the mental number line in normal participants. Thirty-six participants completed a mental number line task before and after adaptation to either: left-shifting prisms, right-shifting prisms or control spectacles that did not shift the visual scene. Participants viewed number triplets (e.g. 16, 36, 55) and determined whether the numerical distance was greater on the left or right side of the inner number. Participants demonstrated (...) a leftward bias (i.e. overestimated the length occupied by numbers located on the left side of the number line) that was consistent with the effect of pseudoneglect. The leftward bias was corrected by a short period of visuomotor adaptation to left-shifting prisms, but remained unaffected by adaptation to right-shifting prisms and control spectacles. The findings demonstrate that a simple visuomotor task alters the representation of space on the mental number line in normal participants. (shrink)

Genomic research results and incidental findings with health implications for a research participant are of potential interest not only to the participant, but also to the participant's family. Yet investigators lack guidance on return of results to relatives, including after the participant's death. In this paper, a national working group offers consensus analysis and recommendations, including an ethical framework to guide investigators in managing this challenging issue, before and after the participant's death.

In this article, I investigate actions that the United States took against Costa Rica during the 1980s in order to argue that current discussions about global justice and its foundations are flawed in three ways. First, it misidentifies the parties of global justice as individual citizens. Second, it conceptualizes global justice as exclusively a distributive justice concern and, as a result, it misidentifies what constitutes a global injustice as being the adverse fate of individuals who live in a poor nation. (...) Finally, the current debate provides no guidance in what must be considered to identify the specific obligations one nation may have to another nation. Given these three problems, I maintain that we conceptualize global injustice as an issue of social justice rather than one exclusively of distributive justice. This will require identifying nations as the parties to global justice, at least in certain cases, and realizing that our goal is to remedy oppressive global structures of power. Utilizing the social justice I propose will put us on the road toward achieving justice across the Americas. (shrink)

The biophilia hypothesis posits an innate biological and genetic connection between human and nature, including an emotional dimension to this connection. Biophilic design builds on this hypothesis in an attempt to design human-nature connections into the built environment. This article builds on this theoretical framework through a meta-analysis of experimental studies on the emotional impacts of human exposure to natural and urban environments. A total of 49 studies were identified, with a combined sample size of 3,201 participants. The primary findings (...) indicated that exposure to natural environments had a medium to large effect on both increasing positive affect and decreasing negative affect. This finding supported the anticipated emotional dimension of the biophilia hypothesis and lends credibility to biophilic design theory. Evidence was revealed in support of the affective/arousal response model. Immersion in environments indicated a larger effect size than laboratory simulation of environments. Methodological recommendations for future experimental research were few, however the Positive and Negative Affect Schedule outcome measure was recommended as a measure of both positive and negative affect for further studies. A combination measurement of stress related outcome variables was proposed to further explore the affective/arousal response model and its potential relationship to the biophilia hypothesis. The meta-analysis provides evidence for fundamental theories regarding human-nature connection, while revealing gaps in current knowledge. (shrink)

Do the dynamics of a physical system determine what function the system computes? Except in special cases, the answer is no: it is often indeterminate what function a given physical system computes. Accordingly, care should be taken when the question ‘What does a particular neuronal system do?’ is answered by hypothesising that the system computes a particular function. The phenomenon of the indeterminacy of computation has important implications for the development of computational explanations of biological systems. Additionally, the phenomenon lends (...) some support to the idea that a single neuronal structure may perform multiple cognitive functions, each subserved by a different computation. We provide an overarching conceptual framework in order to further the philosophical debate on the nature of computational indeterminacy and computational explanation. (shrink)

Résumé: Les analogies peuvent être des outils précieux d’argumentation lors-qu’elles sont bonnes, mais quand elles sont mauvaises, elles faussent inévitablement la question qu’elles sont censées élucider. Tel est le cas de la comparaison entre la sécession et le divorce, qu’il s’agisse du divorce sous conditions ou du divorce sans égard à la faute. L’objectif de cet article est de montrer que la sécession se distingue empirique ment d’un divorce par trois différences significatives: entre personnes et peuple, entre mariage et union (...) politique, et entre divorce et sécession. Cela révèle que les deux versions de l’analogie du divorce sont inadéquates. Même si, cependant, ces écarts pou vaient être comblés et que l’analogie du divorce sous condition puisse être sauvée, je conteste le caractère approprié de l’autre version en montrant qu’aborder la sécession comme un divorce civil entraînerait des implications normatives contre-intuitives qui enlèveraient tout attrait à l’analogie du divorce sans égard à la faute, ou qui amèneraient ceux qui l’emploient à promouvoir des modifications irréalistes aux institutions légales internationales.

Two recent films by Pulitzer Prize-winning playwright, David Mamet, can provide opportunities for observing student reactions to ethically troublesome situations and for discussing business-communication ethics in the classroom. The key question addressed in this article is whether business-communication courses, for example, those in public relations, can encourage students to make the "metaphoric leap" and apply Mamet's messages to class readings and discussions on ethical problems or challenges. Through showing two films in their entirety and conducting focus groups among upper-level undergraduates, (...) the authors find that there is instructional value in using Mamet's films to discuss ethics in business-related settings.

Performance in perceptual tasks often improves with practice. This effect is known as ‘perceptual learning,’ and it has been the source of a great deal of interest and debate over the course of the last century. Here, we consider the effects of perceptual learning within the context of signal detection theory. According to signal detection theory, the improvements that take place with perceptual learning can be due to increases in internal signal strength or decreases in internal noise. We used a (...) combination of psychophysical techniques (external noise masking and double‐pass response consistency) that involve corrupting stimuli with externally added noise to discriminate between the effects of changes in signal and noise as observers learned to identify sets of unfamiliar visual patterns. Although practice reduced thresholds by as much as a factor of 14, internal noise remained virtually fixed throughout training, indicating learning served to predominantly increase the strength of the internal signal. We further examined the specific nature of the changes that took place in signal strength by correlating the externally added noise with observer's decisions across trials (response classification). This technique allowed us to visualize some of the changes that took place in the linear templates used by the observers as learning occurred, as well as test the predictions of a linear template‐matching model. Taken together, the results of our experiments offer important new theoretical constraints on models of perceptual learning. (shrink)

In 2018, at least 12 adults and 3 children died in U.S. detention facilities. In 2017, 12 people died in U.S. detention facilities and at least 10 women filed complaints against ICE for mistreatment that led them to miscarry. At the time of this writing, 26 people have died in US Custody during the Trump Administration and 74 people have died in U.S. detention facilities between 2010 and 2018, including Raul Ernesto Morales-Ramos, Augustina Ramirez-Arreola, Moises Tino-Lopez, Jose Azurdia, and Roxana (...) Hernandez. I am not going to argue that these deaths are wrong – I take that as obvious. Instead, I will suggest that nonideal theory shows why bioethicists have special obligations for condemning these deaths and getting involved to make them stop. When we heed nonideal theory’s demand to consider empirical realities, we will see that the role of the bioethicist extends wherever health care does. Moreover, when bioethicists expressly embrace nonideal rather than ideal theories to ground our work, we will see that there are plenty such theories available to us. Shelly Wilcox’s nonideal theory of immigration justice is especially well suited for bioethicists to use in relation to detainee health care and enter the conversation where they are so desperately needed.

In September 2020, Project South, along with numerous other organizations, released a report detailing abuses in a Georgia Detention Center – including forced hysterectomies. Whatever other factors are at play, one of them is an intrinsic connection between obstetric violence against pregnant migrants and immigration injustice. It is not incidental that these acts – in US detention centers, along the US‐Mexico border, in Colombian hospitals and clinics – are being perpetrated on immigrant bodies. And it is not accidental or random (...) which immigrant bodies are vulnerable to these violations. Understanding and confronting obstetric violence directed at pregnant migrants, though, requires reconceptualizing the nature of obstetric violence itself. In particular, we must recognize that obstetric violence against pregnant Latin American migrants in the United States and Colombia is a type of immigration injustice, a means to perpetrate immigration injustice, and a product of immigration injustice. As such, bioethicists need to collaborate with immigration scholars to resist it.After providing some background on the nature of obstetric violence and some ways it is perpetuated against pregnant migrants in the United States and Colombia, I will give a brief overview of how I conceptualize immigration justice. From there, I explain how this type of obstetric violence constitutes a type of immigration injustice, a means to perpetrate immigration injustice, and a product of immigration injustice. My hope is that this analysis motivates bioethicists throughout the Americas to engage with immigration scholars and activists to confront the issue more forcefully. (shrink)

Despite the fact that the requirement to obtain informed consent for medical procedures is deeply enshrined in both U.S. moral and legal doctrine, empirical studies and anecdotal accounts show that women's rights to informed consent and refusal of treatment are routinely undermined and ignored during childbirth.

At this point, I think it is fair to say that most of us know someone—a family member, a coworker, a friend, a student—who is resisting getting a vaccine against COVID-19. Frankly, this amazes me.

The last fifteen years have seen an increasing social science scholarship into the nature and pervasiveness of hooking up amongst college students,1 but research on the philosophical and ethical issues within hookup culture and practice has not kept pace. To the extent that hooking up has been taken up by philosophers, it has been as part of a larger conversation about the ethics of casual sex, broadly construed; a conversation which is dominated by questions of objectification. As such, investigations into (...) the ethics of hookup sex have been limited to questions of whether someone was used in the encounter.2 This essay aims to change this by utilizing Ann Cahill’s recent book, Overcoming Objectification, to argue that the ethical problems with hookup sex in Guyland are not rooted in women’s objectification but rather their derivatization.

In A Good Birth, obstetrician and bioethicist Anne Drapkin Lyerly aims to improve women’s experiences of childbirth in the United States by cutting through the vitriolic, shame-inducing, and blame-assigning language of what she terms “the birth wars”—the “polarized debate over where birth should be undertaken and how, who is the presumptive attendant, which professionals need to be supervised, and which way the money should flow”. Too often, women like Lyerly’s friend Erin, whom Lyerly interviewed for the book, are the casualties (...) of the birth wars, as they feel ashamed, distraught, and guilty for not giving birth according to the dictates of a particular ideology.

In 2010, Taffy Brodesser-Akner published an article entitled, “How Childbirth Caused my PTSD,” on Salon.com. Much to my surprise, her claims that she was seriously traumatized by childbirth encountered strong resistance and disbelief. In trying to understand the source of this resistance, I discovered a type of violence, which I refer to as “metaphysical violence,” that is often overlooked, yet prevalent, in what many people in the United States understand as normal childbirth practices and protocols. In this essay, I will (...) use María Lugones’s Pilgramages/Peregrinajes to offer a detailed account of what constitutes metaphysical violence, how it functions, and why it is so damaging to at least 9% of post-partum women who meet the criteria for PTSD and the 18% of post-partum women who show some sign of the disorder. Then, I will offer suggestions for how we can help women who may be victims of metaphysical violence during birth avoid some of the trauma it so often induces. (shrink)

Feminists have highlighted various ways in which medicalized childbirth is connected to violence. For example, the literature is replete with examples of court-ordered Cesarean sections, intimidation in the delivery room, women diagnosed with post-traumatic stress disorder as a result of their childbirth experiences. The most common approach to the accusations about the connections between medicalized childbirth and violence has been to investigate the degree to which the evidence bears out their accuracy. In this essay, the author takes a different course; (...) instead of trying to confirm or refute reports of violence in childbirth, she posits that understanding the ways in which violence is connected to medicalized childbirth requires us to note the existence of another form of violence that has not been recognized or discussed up to this point – metaphysical violence. The primary focus of this essay is to define that other form of violence as well as to suggest places where the routine practices of medicalized childbirth perpetuate it and possible ways to resist it.

Alison Bailey has recently explored the nature of what she calls privilege‐evasive epistemic pushback or “the variety of willful ignorance that many members of dominant groups engage in when they are asked to consider both the lived experience and structural injustices that members of marginalized groups experience daily.” In this article, I want to use Bailey's argument to demonstrate how privilege‐evasive epistemic pushback is facilitated and obscured by the disciplinary tools of traditional Western philosophy. Specifically, through exploring philosophical cultures of (...) justification and case studies, this work will reveal how students engage in privilege‐evasive epistemic pushback by deploying the reason/emotion divide and various philosophical norms and practices it underlies to protect their epistemic home turf. Then, I offer three emotion‐enhancing critical philosophical practices aimed at disrupting the ignorance‐promoting moves of privilege‐evasive epistemic pushback and, instead, engage emotion as epistemically significant.
