Researchers in America are developing a hippocampal cognitive prosthesis. The technology aims to improve or even restore memory for people with Alzheimer’s disease through implanting electrodes into the brain. In this paper we discuss the ways that this technology could affect memory, with concomitant potential for impact on personal identity and related attributes like autonomy, agency, and authenticity. To do this we describe how developers of technologies like this adopt functionalist positions on minds and brains, whereby functionally equivalent (...) technology can undertake functions previously executed by the brain without negative impact on mental states. Our position is that such accounts are too uncertain to adopt uncritically, and after examining some critiques of functionalism, we argue that material differences in function could affect the phenomenological experience of mental state generation, including memory. We conclude with proposals for researchers to consider so as to take into account some of these limitations. (shrink)

The aim of the paper is to show the way in which human cognitive system uses external prostheses. Currently developed technologies provide human beings with tools that change their way of functioning in the environment, their understanding and the perspective from which they perceive the world. Modifying systems of thoughts, reasoning and modes of operation non­‑biological prostheses extend human cognitive system. A human being uses non­‑biological interfaces for processing information from the external world.

Recently, bioethicists and the UNCRPD have advocated for supported medical decision-making on behalf of patients with intellectual disabilities. But what does supported decision-making really entail? One compelling framework is Anita Silvers and Leslie Francis’ mental prosthesis account, which envisions supported decision-making as a process in which trustees act as mere appendages for the patient’s will; the trustee provides the cognitive tools the patient requires to realize her conception of her own good. We argue that supported decision-making would be (...) better understood as a collaborative process, giving patients with intellectual disabilities the opportunity to make decisions in a respectful relationship with trusted others. We offer an alternative account of supported decision-making where the primary constraint is to protect the patient from domination by the trustee. This is advantageous in its preservation of the prospects for genuine collaboration, for the mental prosthesis approach ultimately reinforces a problematic ideal of isolated patient self-determination.

Psychogenic depersonalization is an altered mental state consisting of an unusual discontinuity in the phenomenological perception of personal being; the individual is engulfed by feelings of unreality, self-detachment and unfamiliarity in which the self is felt to lack subjective perspective and the intuitive feeling of personal embodiment. A new sub-feature of depersonalization is delineated. 'Prosthesis' consists in the thought that the thinker is a 'mere thing'. It is a subjectively realized sense of the specific and objective 'thingness' of the (...) particular object thought about. I show that prosthesis is an important cognitive feature of depersonalization, and may be psychologically connected with the tendency of depersonalized individuals to report 'philosophical' types of thinking. Indeed, several philosophical issues concerning the identity of the self appear to have been enhanced by prosthesis experiences. Thus, far more efficient than William James's experimental attempts to uncover philosophical truths under the influence of nitrous oxide intoxication, prosthesis may be a safe and recommended experience for philosophers. The history of depersonalization theories is presented from Krishaber to Freud, and the main approaches to prosthesis criticized. Finally, a fresh approach to psychogenic depersonalization is outlined on the basis of certain cognitive similarities with visual agnosia. This paper may be understood as continuing the Jamesian tradition 'experimental abnormal psychology', that is, of examining extraordinary mental states with an eye to their philosophical implications.

Neuropsychiatric disorders introduce distinct challenges to clinical decision-making. Affected patients often experience impairments or absences in rationality, lucidity and cogni-emotional capacities, rendering it difficult for them to engage in the decision-making process. In turn, dynamics of the patient-physician relationship become strained, including when physicians employ bioethical principlism or moral case deliberation to arrive at ethically justified courses of action–both of which require sufficient communication and rationality that may be impaired or altogether absent in the presence of psychopathology. The complexity of (...) neuropsychiatric conditions therefore compels interrogation towards how ethics consultations are currently constructed and conducted when full communication or rational decision-making cannot be assumed. Delany et al, for example, present a robust, methodical framework for ethical deliberation.1 Such methodologies for facilitating ethical decision-making, although valuable in predominant contexts, assume full participant engagement and decision-making capacities (eg, independent moral agency). Neuropsychiatric disorders complicate this assumption, making it difficult for patients with limited decision-making capacity to engage meaningfully in proposed ethics consultations.2 This paper will explore how neuropsychiatric disorders complicate the assumptions of full participant engagement underlying ethical frameworks. It will argue that, by adapting ethics consultations to function as a ‘mental prosthesis’, clinicians can better navigate the ethical challenges posed by neuropsychiatric disorders, helping to ensure that patient autonomy is upheld even in cases of impaired cognitive ….

Information management systems improve the retention of information in large collections. As such they act as memory prostheses, implying an ideal basis in human memory models. Since humans process information by association, and situate it in the context of space and time, systems should maximize their effectiveness by mimicking these functions. Since human attentional capacity is limited, systems should scaffold cognitive efforts in a comprehensible manner. We propose the Principles of Mnemonic Associative Knowledge (P-MAK), which describes a framework for (...) semantically identifying, organizing, and retrieving information, and for encoding episodic events by time and stimuli. Inspired by prominent human memory models, we propose associative networks as a preferred representation. Networks are ideal for their parsimony, flexibility, and ease of inspection. Networks also possess topological properties—such as clusters, hubs, and the small world—that aid analysis and navigation in an information space. Our cognitive perspective addresses fundamental problems faced by information management systems, in particular the retrieval of related items and the representation of context. We present evidence from neuroscience and memory research in support of this approach, and discuss the implications of systems design within the constraints of P-MAK’s principles, using text documents as an illustrative semantic domain.

Although there have been many efforts in the last decade to reconcile the humanities and the information sciences, they have not radically changed the research standards prevailing in most humanistic departments. Against all appearances, the abrupt opening to quantitative methods in the digital humanities still has the character of a minority avant-garde movement.

An account (...) of scientometric networks highlights the advantages and disadvantages of this orientation. The broader implications regarding the use of visual networks in the humanities are framed by the category of prostheticity, which aims to encapsulate their ambivalent status as both substitutes and cognitive enhancers.

This paper investigates the role of a pre-existing body-model that is an enabling constraint for the incorporation of objects into the body. This body-model is also a basis for the distinction between body extensions (e.g., in the case of tool-use) and incorporation (e.g., in the case of successful prosthesis use).

Writing is frequently analyzed as a mode of communication. But writing can be done for personal reasons, to remind oneself of things to do, of thoughts, of events. The cellphone has revealed this shift, commencing as a communication device and ending up as a memory prosthesis that records what we see, hear, read and think. The recordings are not necessarily for communicating a message to others, but sometimes just for oneself. Today, when machine learning algorithms read, write and transmit, (...) a new mode of communication arises that is not centered on the human. In this chapter the various phases of modern writing are modeled according to postphenomenology. As a branch of philosophy of technology, postphenomenology offers a set of analytical tools to study technologies and our relations to them. One of its central frameworks is the scheme of “I–technology–world.” The author proposes some modifications so that the scheme can systematically model the changes in the humans users, in machine learning algorithms imbued with non-human cognition and in the environments of readers, interlocutors and contexts.

Many upper limb amputees experience an incessant, post-amputation “phantom limb pain” and report that their missing limbs feel paralyzed in an uncomfortable posture. One hypothesis is that efferent commands no longer generate expected afferent signals, such as proprioceptive feedback from changes in limb configuration, and that the mismatch of motor commands and visual feedback is interpreted as pain. Non-invasive therapeutic techniques for treating phantom limb pain, such as mirror visual feedback (MVF), rely on visualizations of postural changes. Advances in neural (...) interfaces for artificial sensory feedback now make it possible to combine MVF with a high-tech “rubber hand” illusion, in which subjects develop a sense of embodiment with a fake hand when subjected to congruent visual and somatosensory feedback. We discuss clinical benefits that could arise from the confluence of known concepts such as MVF and the rubber hand illusion, and new technologies such as neural interfaces for sensory feedback and highly sensorized robot hand testbeds, such as the “BairClaw” presented here. Our multi-articulating, anthropomorphic robot testbed can be used to study proprioceptive and tactile sensory stimuli during physical finger-object interactions. Conceived for artificial grasp, manipulation, and haptic exploration, the BairClaw could also be used for future studies on the neurorehabilitation of somatosensory disorders due to upper limb impairment or loss. A remote actuation system enables the modular control of tendon-driven hands. The artificial proprioception system enables direct measurement of joint angles and tendon tensions while temperature, vibration, and skin deformation are provided by a multimodal tactile sensor. The provision of multimodal sensory feedback that is spatiotemporally consistent with commanded actions could lead to benefits such as reduced phantom limb pain, and increased prosthesis use due to improved functionality and reduced cognitive burden.

Language is the original technological prosthesis mediating all transfer of human cognition. The relationships between language, communication and cognition have long been the subject of scientific, philosophic and linguistic inquiry. However, it is through contemporary advancements in neuroscience that we now have unprecedented access to the inner workings of the human brain. Particularly, consumer grade neural scanning technologies like the Muse headset allow non-scientists to view, manipulate and draw conclusions from data generated by their own neural processes. Hence, artists (...) Minka Stoyanova and Lisa Park SoYoung have created an artistic experimental system that utilizes these technologies to address the possibility of communication beyond the confines of linguistic signification. Performing Hypo-Linguistics uses Muse brain sensors to create an abstract audio-visual communication system and feedback loop. Through the visualization and sonification of their respective brain data, these artists perform communication that is both outside of conscious control and beyond sign-based systems of linguistic representation. In this article, we discuss the philosophic and scientific groundwork that supports the creation of this system; our processes of sonification and visualization of the Muse-generated brain data (including the modes by which we actively avoided signification and expected technological aesthetics of data representation); and the outcomes of the performances or the realized interaction between the performers. As deep-learning algorithms become increasingly able to teach computers to mimic human language, it becomes ever more apparent that language is not, in fact, the purview of the human, but only one technological mode invented to facilitate the transfer of information. As with all systems of communication, noise is introduced in this process of transfer. This artistic research seeks to highlight that reality while considering the potentials for alternative forms of technologically mediated communication beyond linguistic signification and below the level of consciousness.

A goal of expanding life over time, space, and substrate requires that we look beneath the surface of technology and the universal norms placed on human nature to a vision of its future that could be realized. There is a visible fracturing of the personal and social behaviors of its hybrid users – a process that we might call data‐clatter. While life expansion seeks the continuation of persons over time and space and beyond the physical body, there is no current (...) method for backing up the brain and transferring its processes outside the biological system. The objectives of life expansion include developing a whole‐body prosthesis as both a device for mobility and sensory perception and a system that streams cognitive functions. These systems would provide the biosphere for biological systems of humans and the cybersphere for computational systems of digital persons. (shrink)

Since the development of the first neural prosthesis, that is, the cochlear implant in 1957, neural prosthetics have been one of the highly promising, yet most challenging areas of medicine, while having become a clinically accepted form of invasiveness into the human body. Neural prosthetic devices, of which at least one part is inserted into the body, interact directly with the nervous system to restore or replace lost or damaged sensory, motor, or cognitive functions. This field is not (...) homogenous and encompasses a variety of technologies, which are in various stages of development.

By comparison, other technologies are in experimental phases and still need to be further developed to achieve the desired results. (shrink)

Gli storici della filosofia solitamente attribuiscono ai pensatori moderni l'invenzioni di concetto "soggetto", "oggetto" e "soggettività" e li concepiscono in direttamente in contrasto con la filosofia scolastica e aristotelica. Questo articolo suggerisce la presenza di una proto-teoria della soggettività in Aristotele. La teoria aristotelica della soggettività è fondata principalmente su quattro dottrine. In primo luogo, si può riscontrare nell'epistemologia aristotelica la presenza di una "prospettiva" e di un "punto di vista". Il secondo aspetto significativo è il concetto di determinazione dell'oggetto (...) della conoscenza, che nella filosofia aristotelica è rappresentato dalla nozione di "prosthesis". La terza dottrina si fonda sulla distinzione fra ciò che è più conoscibile per noi e ciò che è più conoscibile per natura. L'ultima dottrina riguarda la seconda natura del soggetto e gli abiti della conoscenza acquisiti attraverso l'esperienza, i quali spiegano perché i soggetti abbiano conoscenze diverse degli stessi oggetti secondo le loro precedenti esperienzePhilosophers usually attribute to modernity the invention of concepts like 'subject', 'object' and 'subjectivity' and they understand them in contrast to Scholastic and Aristotelian philosophies. The present paper suggests the presence of a proto-theory of subjectivity in Aristotle. The Aristotelian theory of subjectivity is grounded principally on four doctrines. First, we can recognize the presence of a 'perspective' and of a 'point of view' in the Aristotelian epistemology. The second relevant aspect is the concept of determination of the object of knowledge, which is in Aristotelian philosophy the notion of 'prosthesis'. The third doctrine lies on the distinction between 'what is more known to us' and 'what is more known by nature'. The last doctrine concerns the 'second nature' of the subject and the habits of knowledge acquired by experience, which explain why knowing subjects have different cognitions of the same object according to their own previous experience.

In lieu of an abstract, here is a brief excerpt of the content:The Happiness of “Those Who Lack the Use of Reason”Miguel J. RomeroHuman beings would have been created uselessly and in vain were they unable to attain happiness, as would be the case with anything that cannot attain its ultimate end.(De Malo, q. 5, a. 1, ad 1)A STUDY OF “those who lack the use of reason” in the thought and spirit of St. Thomas Aquinas has much to offer (...) the patient reader. We better understand what it means to be a rational animal, the image of triune God, when we investigate why, exactly, “mindless persons” (amentes) are not exceptions or even outliers in Aquinas’s account of the creaturely dignity and perfectibility of the human being.Aquinas remarks with some regularity on persons afflicted with the condition amentia, which is variously and inconsistently interpreted (in translation) as “imbeciles,” “fools,” “madmen,” “lunatics,” “the demented,” or “the insane.” The amentes are persons who lack the use of reason in a profound and debilitating way; and, as I will show, the fact that we are sometimes found in this state informs Aquinas’s analysis of human nature and, in particular, Aquinas’s teaching on the good wrought by Christ for the members of his body. Our guiding question is this: Thinking with Aquinas, how do we account for the natural and supernatural happiness of those of us who lack the use of reason?My purpose in this article is to explore what Aquinas has to say about the happiness of persons who are baptized and [End Page 49] confirmed by the Church, and who have what neuro-psychologists would describe as a profound cognitive impairment. The question is particularly striking when we recall that, for Aquinas, the distinguishing aptitude of the human being (proper to our intellectual nature and coordinate with our creaturely perfection) is the operation of an incorruptible intellectual capacity—a capacity, however, that is only reduced from potentiality to act when the corruptible “internal sense organ” is disposed to receive, in terms of health and circumstance, a coordinated sense impression of material species. Thus, a further question emerges: According to Aquinas, what is the perfective effect of grace in this life upon the nature of a person who completely lacks the use of reason due to an organic corruption or disorder of the ‘internal sense organ’?The discussion is divided into five parts. I begin (part I) by locating those who “lack the use of reason” within the theological infrastructure of Aquinas’s moral psychology and I identify the main problematic. With respect to that problematic, the principal conceptual resources provided by Aquinas are then outlined and two challenges are identified (part II).The first challenge is methodological, concerning the speculative import of the sacramental life of the Church. Francisco de Vitoria’s Relectio de eo ad quod tenetur homo veniens ad usum rationis (1534) highlights for us (part III) a constellation of judgments relevant to interpreting Aquinas on these themes, in particular, Aquinas’s formulation of prerational intellectual acts vis-à-vis the participation and membership of “mindless persons” in the sacramental life of the Body of Christ.The second challenge is to show the continuity between Aquinas’s account of the human being and his practical remarks on those who lack the use of reason. Specifically, given the various ways that, and degrees to which, the human being can lack the use of reason, I trace (part IV) Aquinas’s analysis of the power and operation of intellect, focusing on the intellectual acts which can be impaired and, concurrently, the intellectual acts which cannot be impaired in a living human being. Aquinas’s remarks on those latter acts not only reflect the [End Page 50] significance of the doctrine of the image of God in his account of human nature, but, even more, they shed light on the prosthesis of sacramental grace in his understanding of the properly human happiness capacitated and purposed in all whom God has called in Christ—a call to discipleship and devotion that includes those of us who have a profound, lifelong cognitive impairment (Rom 8:28; 9:11; Eph 1:3-14; II Tim 1:8-11).I conclude...

Cognitive enhancement (CE) covers a broad spectrum of methods, including behavioral techniques, nootropic drugs, and neuromodulation interventions. However, research on their use in children has almost exclusively been carried out in high-income countries with limited understanding of how experts working with children view their use in low- and middle- income countries (LMICs). This study examines perceptions on cognitive enhancement, their techniques, neuroethical issues about their use from an LMICs perspective.Seven Indian experts were purposively sampled for their expertise in (...) bioethics, child development and child education. In-depth interviews were conducted using a semi-structured topic guide to examine (1) understanding of CE, (2) which approaches were viewed as cognitive enhancers, (3) attitudes toward different CE techniques and (4) neuroethical issues related to CE use within the Indian context. All interviews were audio recorded and transcribed before thematic analysis.Findings indicate Indian experts view cognitive enhancement as a holistic positive impact on overall functioning and well-being, rather than improvement in specific cognitive abilities. Exogenous agents, and neuromodulation were viewed with skepticism, whereas behavioral approaches were viewed more favorably. Neuroethical concerns included equitable access to CE, limited scientific evidence and over-reliance on technology to address societal problems. This highlights the need for more contextually relevant neuroethics research in LMICs. (shrink)

This paper addresses the recent rise of the use of alternative medicine in Western countries. It offers a novel explanation of that phenomenon in terms of cognitive and economic factors related to the free-market and patient-centric approach to medicine that is currently in place in those countries, in contrast to some alternative explanations of this phenomenon. Moreover, the paper addresses this troubling trend in terms of the serious harms associated with the use of alternative medical modalities. The explanatory theory (...) defended here is then predicated on the idea that an extreme patient-centric model of medical practice that treats largely ignorant patients as consumers of medical products and services endowed with an essentially unrestricted power of freedom to choose treatments predictably leads serious and avoidable harms. Some important moral and epistemological consequences of this model are then articulated and corrective measures are suggested. (shrink)

The sample included the participation of (...) spirit mediums divided into two groups. The more experienced group with 11 subjects had more than 10 years of mediumistic practice, while the other less experienced group with 8 subjects had 1–5 years of experience. The inclusion criteria were psychophonic mediums with regular trance practices for at least one year. The data collected were analyzed using the SPSS statistical package.ResultsRegarding performance on the BCSB and digit span test, all subjects reached scores at the median or higher in comparison to standardized scores of Brazilians. Scores of 90% on the cube test and 42% on the FAS were reached in comparison to median or higher values, versus the median of standardized scores among Brazilians. On the FDT, we found statistical significance in the choice stage, with higher performance of subjects whose initial age of trance recognition occurred before 21 years old. On the BDI scale, no participant met the criteria for major depression. The SRQ showed an incidence of common mental disorders in 21% of the sample, which was more prevalent in the LEG.ConclusionThe cognitive functioning of subjects who practice trance mediumship in Brazil is associated with cognitive health. Executive dysfunction may be a tendency in LEG. However, an incidence of common mental disorders in the LEG was observed. Executive processing was higher in the subgroup with early practices of recognizing the phenomenon. (shrink)

The problem of intentional identity, as originally offered by Peter Geach, says that there can be an anaphoric link between an indefinite term and a pronoun across a sentential boundary and across propositional attitude contexts, where the actual existence of an individual for the indefinite term is not presupposed. In this paper, a semantic resolution to this elusive puzzle is suggested, based on a new quantified intensional logic and game-theoretic semantics (GTS) of imperfect information. This constellation leads to an expressive (...) intensional language with a property of informational independence, argued to produce a purely semantic explication to intentional identity statements. One consequence is that various extra-logical and pragmatic factors become of secondary concern; it is possible to solve the puzzle by logico-semantic methods, albeit somewhat radically renewed ones.

Changing and often class-dependent non-stationarities of signals are a big challenge in the transfer of common findings in cognitive workload estimation using Electroencephalography (EEG) from laboratory experiments to realistic scenarios or other experiments. Additionally, it often remains an open question whether actual cognitive workload reflected by brain signals was the main contribution to the estimation or discriminative and class-dependent muscle and eye activity, which can be secondary effects of changing workload levels. Within this study, we investigated a novel (...) approach to spatial filtering based on beamforming adapted to changing settings. We compare it to no spatial filtering and Common Spatial Patterns (CSP). We used a realistic maneuvering task, as well as an auditoryn-backsecondary task on a tugboat simulator as two different conditions to induce workload changes on professional tugboat captains. Apart from the typical within condition classification, we investigated the ability of the different classification methods to transfer between then-backcondition and the maneuvering task. The results show a clear advantage of the proposed approach over the others in the challenging transfer setting. While no filtering leads to lowest within-condition normalized classification loss on average in two scenarios (22 and 10%), our approach using adaptive beamforming (30 and 18%) performs comparably to CSP (33 and 15%). Importantly, in the transfer from one to another setting, no filtering and CSP lead to performance around chance level (45 to 53%), while our approach in contrast is the only one capable of classifying in all other scenarios (34 and 35%) with a significant difference from chance level. The changing signal composition over the scenarios leads to a need to adapt the spatial filtering in order to be transferable. With our approach, the transfer is successful due to filtering being optimized for the extraction of neural components and additional investigation of their scalp patterns revealed mainly neural origin. Interesting findings are that rather the patterns slightly change between conditions. We conclude that the approaches with low normalized loss depend on eye and muscle activity which is successful for classification within conditions, but fail in the classifier transfer since eye and muscle contributions are highly condition-specific.

One of the most fruitful interdisciplinary boundaries in contemporary scholarship is that between philosophy and cognitive science. Now that solid empirical results about the activities of the human mind are available, it is no longer necessary for philosophers to practice armchair psychology.

Besides providing a valuable review of the most suggestive work in (...) class='Hi'>cognitive and social psychology, Goldman demonstrates conclusively that the best work in philosophy in a surprising number of different fields―including philosophy of science, epistemology, metaphysics, and ethics as well as philosophy of mind―must take into account empirical breakthroughs in psychology.

It will also interest researchers and students in psychology who are intrigued by the wider theoretical implications of their work. (shrink)

This paper advances the view that some explanations in cognitive science are extra-mathematical explanations. Demonstrating the plausibility of this interpretation centers around certain efficient coding cases which ineliminably enlist information theoretic laws, facts and theorems to identify in-principle, mathematical constraints on neuronal information processing capacities. The explanatory structure in these cases is shown to parallel other putative instances of mathematical explanation. The upshot for cognitive mathematical explanations is thus two-fold: first, the view capably rebuts standard mechanistic objections to (...) non-mechanistic explanation; second, this view serves to importantly widen the possibility space for non-mechanistic forms of explanation in cognitive science.

The Cognitive Estimation Test is widely used by clinicians and researchers to assess the ability to produce reasonable cognitive estimates. Although several studies have published normative data for versions of the CET, many of the items are now outdated and parallel forms of the test do not exist to allow cognitive estimation abilities to be assessed on more than one occasion. In the present study, we devised two new 9-item parallel forms of the CET. These versions were (...) administered to 184 healthy male and female participants aged 18–79 years with 9–22 years of education. Increasing age and years of education were found to be associated with successful CET performance as well as gender, intellect, naming, arithmetic and semantic memory abilities. To validate that the parallel forms of the CET were sensitive to frontal lobe damage, both versions were administered to 24 patients with frontal lobe lesions and 48 age-, gender- and education-matched controls. The frontal patients’ error scores were significantly higher than the healthy controls on both versions of the task. This study provides normative data for parallel forms of the CET for adults which are also suitable for assessing frontal lobe dysfunction on more than one occasion without practice effects.

In philosophy, a debate can live forever. Nowhere is this more evident than in ethics, a field that is fueled by apparently intractable dilemmas. To promote the wellbeing of many, may we sacrifice the rights of a few? If our actions are predetermined, can we be held responsible for them? Should people be judged on their intentions alone, or also by the consequences of their behavior? Is failing to prevent someone’s death as blameworthy as actively causing it? For generations, questions (...) like these have provoked passionate arguments and counterarguments, but few clear answers. Here, we offer a psychological account of why philosophical dilemmas arise, why they resist resolution, and why scientists should pay attention to them. Building on a family of recent proposals (Cushman & Young, 2009; Greene, 2008; Sinnott- Armstrong, 2008), we argue that dilemmas result from conflict between dissociable psychological processes. When two such processes yield different answers to the same question, that question becomes a “dilemma”. No matter which answer you choose, part of you walks away dissatisfied. This explanation of philosophical dilemmas has an important payoff for psychological research, and we discuss two specific cases in which it has yielded promising results. In each case, social neuroscience has played an important role in distinguishing the psychological processes responsible for producing a dilemma. This, we suggest, is no accident; cognitive neuroscientific methods are particularly well-suited to dissociating independent psychological processes (Henson, 2006). Consequently, philosophers’ dilemmas provide a reliable guide toward productive cognitive neuroscience by identifying the contours of distinct psychological process. The research we review below focuses particularly on moral dilemmas, which is our own area of expertise. The psychological processes that contribute to moral judgment are of interest in their own right, and play a central role in social cognition.. (shrink)

In this paper, I outline two strands of evidence for the conclusion that the dynamical approach to cognitive science both seeks and provides covering law explanations. Two of the most successful dynamical models—Kelso’s model of rhythmic finger movement and Thelen et al.’s model of infant perseverative reaching—can be seen to provide explanations which conform to the famous explanatory scheme first put forward by Hempel and Oppenheim. In addition, many prominent advocates of the dynamical approach also express the provision of (...) this kind of explanation as a goal of dynamical cognitive science. I conclude by briefly outlining two consequences. First, dynamical cognitive science’s explanatory style may strengthen its links to the so-called “situated” approach to cognition, but, secondly, it may also undermine the widespread intuition that dynamics is related to emergentism in the philosophy of mind.

The cognitive experience view of thought holds that the content of thought is determined by its cognitive-phenomenal character. Adam Pautz argues that the cognitive experience view is extensionally inadequate: it entails the possibility of mix-and-match cases, where the cognitive-phenomenal properties that determine thought content are combined with different sensory-phenomenal and functional properties. Because mix-and-match cases are metaphysically impossible, Pautz argues, the cognitive experience view should be rejected. This paper defends the cognitive experience view from (...) Pautz’s argument. I build on resources in the philosophy of mind literature to show that cognitive-phenomenal properties are modally independent from sensory-phenomenal and functional properties. The result is that mix-and-match cases, though modally remote, are metaphysically possible. The possibility of mix-and-match cases allows us to move from defensive posture to a critical one: it poses problems for any theory of content that imposes rationality constraints, including Pautz’s positive view, phenomenal functionalism.

We consider ability and motivation variables integrated and adapted into a cognitive elaboration model for sustainable decision making. Specifically, we examine the degree of influence of two factors on (...) the ethical sensitivity to sustainability: the moral maturity of the individual, and the perceived moral intensity of a sustainability issue. Our investigation offers insights into how financial managers perceive the importance of sustainability for corporate strategy. (shrink)

We investigated the acceptability and frequency of the use of cognitive enhancement (CE) drugs and three different types of academic misconduct (plagiarism, cheating in exams, and falsifying/fabricating data). Data from a web-based survey among German university students were used. Moral acceptability was relatively low for CE drug use and moderate for academic misconduct, while the correlation of their respective acceptability was moderately weak. Prevalence of CE drug use was lower than for academic misconduct and (very) lightly correlated with the (...) prevalence of plagiarism and fabrication/falsification. Acceptability of the investigated behaviors was associated with higher prevalence rates of each behavior. (shrink)

Military personnel often perform complex cognitive operations under unique conditions of intense stress. This requirement to perform diverse physical and mental tasks under stress, often with high stakes, has led to recognition of the term ‘tactical athlete’ for these performers. Impaired cognitive performance as a result of this stress may have serious implications for the success of military operations and the well-being of military service men and women, particularly in combat scenarios. Therefore, understanding the nature of the stress (...) experienced by military personnel and the resilience of cognitive functioning to this stress is of great importance. This review synthesises the current state of the literature regarding cognitive resilience to psychological stress in tactical athletes. The experience of psychological stress in military personnel is considered through the lens of the Transactional Theory of stress, while offering contemporary updates and new insights. Models of the effects of stress on cognitive performance are then reviewed to highlight the complexity of this interaction before considering recent advancements in the preparation of military personnel for the enhancement of cognitive resilience. Several areas for future research are identified throughout the review, emphasising the need for the wider use of self-report measures and mixed methods approaches to better reflect the subjective experience of stress and its impact on the performance of cognitive operations.

The article first addresses the importance of cognitive modeling, in terms of its value to cognitive science (as well as other social and behavioral sciences). In particular, it emphasizes the use of cognitive architectures in this undertaking. Based on this approach, the article addresses, in detail, the idea of a multi-level approach that ranges from social to neural levels. In physical sciences, a rigorous set of theories is a hierarchy of descriptions/explanations, in which causal relationships among entities (...) at a high level can be reduced to causal relationships among simpler entities at a more detailed level. We argue that a similar hierarchy makes possible an equally productive approach toward cognitive modeling. The levels of models that we conceive in relation to cognition include, at the highest level, sociological/anthropological models of collective human behavior, behavioral models of individual performance, cognitive models involving detailed mechanisms, representations, and processes, as well as biological/physiological models of neural circuits, brain regions, and other detailed biological processes.
