Language is a cognitively demanding human trait, but it is also a fundamentally cooperative enterprise that rests on the motivation to share information. Great apes possess many of the cognitive prerequisites for language, but largely lack the motivation to share information. Callitrichids (including marmosets and tamarins) are highly vocal monkeys that are more distantly related to humans than great apes are, but like humans, they are cooperative breeders and all group members help raising offspring. Among primates, this rearing (...) system is correlated with proactive prosociality, which can be expressed as motivation to share information. We therefore propose that the unique coincidence of these two components in humans set the stage for language evolution: The cognitive component inherited from our great ape-like ancestors, and the motivational one added convergently as a result of cooperative breeding. We evaluate this scenario based on a review of callitrichd vocal communication and show that furthermore, they possess many of the mechanistic elements emphasized by the mirror system hypothesis of language evolution. We end by highlighting how more systematic phylogenetic comparisons will enable us to further promote our understanding of the role of cooperative breeding during language evolution. (shrink)

In arbitrating between representational and relational theories of perception, perceptual illusions—cases in which a subject’s perceptual experience diverges from the way the world really is—constitute an important battleground. The debate has, however, been dominated by discussions of visual perception. In attempting to extend the debate to audition, it is appropriate to start by considering what is thought to be a key case of auditory illusion. I consider the phenomenon of the ‘missing fundamental’, as well as examining a notion that (...) is often deployed by representationalists to explain it—namely, perceptual inference. Though it is frequently deployed as an explanatory concept by inferentialists, the notion of perceptual inference is somewhat opaque. Here, I formulate a ‘job description’ for perceptual inference, involving rule-following. I then identify two sets of cases that commonly prompt the invocation of perceptual inference: namely, cases of perceptual illusion, and cases of veridical perception where the perceptual content outstrips the information present in the stimulus. I then argue that an appeal to perceptual inference is unnecessary, in the case of the missing fundamental, for two reasons. Firstly, the missing fundamental is not, after all, a clear candidate for the ascription of inferential capacity to the auditory system: it is neither an illusion, nor is it the case that the stimulus is crucially impoverished. That is, it submits to a ‘direct’ explanation. Secondly, given the adequacy of a simpler explanation, and the difficulty between distinguishing between real rule-following and the mere appearance of it, I argue that we should avoid ascribing inferential capacity to the auditory system. I close by considering objections, and offering replies. (shrink)

You might reasonably surmise from the title of this paper that I will be discussing a theory of vision. After all, what is a theory of vision but a theory of how the world is connected to our visual representations? Theories of visual perception universally attempt to give an account of how a proximal stimulus (presumably a pattern impinging on the retina) can lead to a rich representation of a three dimensional world and thence to either the recognition of (...) known objects or to the coordination of actions with visual information. Such theories typically provide an effective (i.e., computable) mapping from a 2D pattern to a representation of a 3D scene, usually in the form of a symbol structure. But such a mapping, though undoubtedly the essential purpose of a theory of vision, leaves at least one serious problem that I intend to discuss here. It is this problem, rather than a theory of vision itself, that is the subject of this talk. (shrink)

Hands are commonly held up as an exemplar of well-known, familiar objects. However, conceptual knowledge of the hand has been found to show highly stereotyped distortions. Specifically, people judge their knuckles as farther forward in the hand than they actually are. The cause of this distal bias remains unclear. In Experiment 1, we tested whether both visual and tactile information contribute to the distortion. Participants judged the location of their knuckles by pointing to the location on their palm directly (...) opposite each knuckle with: 1) a metal baton (using vision and touch) 2) a metal baton while blindfolded (using touch), 3) a laser pointer (using vision). In Experiment 2, we investigated whether judgments are influenced by visual landmarks such as the creases at the base of each finger on the palm. Participants localized their knuckles on either a photograph or a silhouette of their hand. In both experiments, clear distortions were found across conditions, of generally similar magnitude. These results show that distal bias is resistant to changes in the stimulus information and does not rely on any specific stimulus cue or single sensory modality, suggesting that such mislocalisations reflect a conceptual misrepresentation of hand structure.

The distinction between receptive field and conceptual field is appealing and heuristically useful. Conceptually, it is more satisfactory to distinguish between information from the environment and from the brain. We emphasize here a selectionist view that considers information transmission within the brain as modulated by a stimulus, rather than information transmission from a stimulus as modulated by the context.

The evaluative conditioning effect refers to the change in the liking of a neutral stimulus due to its pairing with another stimulus. We examined whether the extinction rate of the EC effect is moderated by feature-specific attention allocation. In two experiments, CSs were abstract Gabor patches varying along two orthogonal, perceptual dimensions. During the acquisition phase, one of these dimensions was predictive of the valence of the USs. During the extinction phase, CSs were presented alone and participants were (...) asked to categorise the CSs either according to their valence, the perceptual dimension that was task-relevant during the acquisition phase, or a perceptual dimension that was task-irrelevant during the acquisition phase. As predicted, explicit valence measures revealed a linear increase in the extinction rate of the EC effect as participants were encouraged to assign attention to non-evaluative stimulus information during the extinction phase. In Experiment 1, Affect Misattribution Paradigm data mimicked this pattern of results, although the effect just missed conventional levels of significance. In Experiment 2, the AMP data revealed an increase of the EC effect if attention was focused on evaluative stimulus information. Potential mechanisms to explain these findings are discussed.

This paper argues that the missing voice in clinical ethics is that of informal caregivers. Despite their substantial contribution to care provided to individuals with disabilities, chronic illness or dementia, informal caregivers are rarely thought of as members of the healthcare team and their narratives are rarely listened to and included in clinical and ethical decisions. Addressing this gap, this paper discusses the reasons for the systemic misrecognition of informal caregivers in healthcare systems and argues for their greater narrative (...) inclusion on the clinical, legal and social planes.

Climate change education (CCE) and environmental education (EE) seek ways for us humans to keep inhabiting Earth. We present a thought experiment adopting the perspective of Earth-settlers, aiming to illuminate the planetary mass of technology. By elaborating Hannah Arendt’s notion of ‘earth alienation’ and Bruno Latour’s notion of technology as ‘missing mass’, we suggest that, in the current Anthropocene era, our relation to technology should be a crucial theme of CCE and EE. We further suspect that sustainable development (SD) (...) and the education promoting it (ESD) are problematic, because the green growth proposed is inextricably linked to the unattainable goal of decoupling growth from environmental impact. We therefore suggest education for post-sustainability (EPS) that critically re-evaluates the connections between technology and sustainability. But can educators critically question technology, since educational institutions seem to be unconditionally committed to promoting technological progress? While tracing this professional dilemma, we call for educational responsibility and autonomy to question technology when it is at odds with sustainability. To this end, we outline technological literacy that introduces the arts of (a) seeing technology, (b) living with technology, and (c) delegating or sustainably assimilating technology. (shrink)

Self-relevance has been demonstrated to impair instrumental learning. Compared to unfamiliar symbols associated with a friend, analogous stimuli linked with the self are learned more slowly. What is not yet understood, however, is whether this effect extends beyond arbitrary stimuli to material with intrinsically meaningful properties. Take, for example, stimulus valence an established moderator of self-bias. Does the desirability of to-be-learned material influence self-learning? Here, in conjunction with computational modelling (i.e. Reinforcement Learning Drift Diffusion Model analysis), a probabilistic selection (...) task was used to establish if and how stimulus valence (i.e. desirable/undesirable posters) impacts the acquisition of knowledge relating to object-ownership (i.e. owned-by-self vs. owned-by-friend). Several interesting results were observed. First, undesirable posters were learned more rapidly for self compared to friend, an effect that was reversed for desirable posters. Second, learning rates were accompanied by associated differences in reward sensitivity toward desirable and undesirable choice selections as a function of ownership. Third, decisional caution was greater for self-relevant (vs. friend relevant) responses. Collectively, these findings inform understanding of self-function and how valence and stimulus relevance mutually influence probabilistic learning. (shrink)

Stem cell tourism is a growing industry in which patients pursue unproven stem cell therapies for a wide variety of illnesses and conditions. It is a challenging market to regulate due to a number of factors including its international, online, direct-to-consumer approach. Calls to provide education and information to patients, their families, physicians, and the general public about the risks associated with stem cell tourism are mounting. Initial studies examining the perceptions of patients who have pursued stem cell tourism (...) indicate many are highly critical of the research and regulatory systems in their home countries and believe them to be stagnant and unresponsive to patient needs. We suggest that educational material should include an explanation of the translational research process, in addition to other aspects of stem cell tourism, as one means to help promote greater understanding and, ideally, curb patient demand for unproven stem cell interventions. The material provided must stress that strong scientific research is required in order for therapies to be safe and have a greater chance at being effective. Through an analysis of educational material on stem cell tourism and translational stem cell research from patient groups and scientific societies, we describe essential elements that should be conveyed in educational material provided to patients. Although we support the broad dissemination of educational material on stem cell translational research, we also acknowledge that education may simply not be enough to engender patient and public trust in domestic research and regulatory systems. However, promoting patient autonomy by providing good quality information to patients so they can make better informed decisions is valuable in itself, irrespective of whether it serves as an effective deterrent of stem cell tourism.

Stem cell tourism is a form of medical tourism in which patients travel to receive unproven or untested stem cell-based interventions for many different diseases and conditions. A few studies indicate that patients and the public have several reasons for seeking these treatments for themselves or for their loved ones. Among these are the feeling of not having any other clinical options left, distrust of or frustration with their home country’s health care system, and a perception that their home country (...) has a burdensome or sluggish regulatory system for the approval of novel stem cell therapies. These last two viewpoints may contribute to a certain sense of distrust of regulatory agencies governing the conduct of clinical research, and perhaps the perception of a health care system that seems unresponsive to the needs of patients suffering from severe conditions.

Traditional approaches to human information processing tend to deal with perception and action planning in isolation, so that an adequate account of the perception-action interface is still missing. On the perceptual side, the dominant cognitive view largely underestimates, and thus fails to account for, the impact of action-related processes on both the processing of perceptual information and on perceptual learning. On the action side, most approaches conceive of action planning as a mere continuation of stimulus processing, (...) thus failing to account for the goal-directedness of even the simplest reaction in an experimental task. We propose a new framework for a more adequate theoretical treatment of perception and action planning, in which perceptual contents and action plans are coded in a common representational medium by feature codes with distal reference. Perceived events (perceptions) and to-be-produced events (actions) are equally represented by integrated, task-tuned networks of feature codes – cognitive structures we call event codes. We give an overview of evidence from a wide variety of empirical domains, such as spatial stimulus-response compatibility, sensorimotor synchronization, and ideomotor action, showing that our main assumptions are well supported by the data. Key Words: action planning; binding; common coding; event coding; feature integration; perception; perception-action interface. (shrink)

This chapter tries to make sense of a particular aspect of our contemporary experience: the so-called “post-truth era.” This era is characterized by strong polarization where it seems like the arguments and opinions of the opposing sides are informed by different realities. When beliefs are still held despite being debunked by contradicting evidence, it is easy to dismiss the opponent as “irrational,” resulting in breakdown of communication. This chapter argues that such beliefs may still feel right because they connect to (...) something deeper in the bodily awareness and lived experience, which Eugene Gendlin calls the “felt sense” or “felt meaning.” When we are disconnected from this bodily sense, it can result in various articulations which do not make sense at a surface level but critiquing the surface level articulations while ignoring their source often results in frustration and anger. Rather than dismissing people’s rationality, we should assume they have reasons for holding their beliefs, although they may not be able to articulate those reasons. Drawing on the works of Gendlin I argue for a sympathetic yet critical listening to the bodily sense which requires attention to the whole situation of our social environment. (shrink)

A recent study suggests that vaccine hesitancy amongst key demographics – including females, younger individuals, and certain ethnic groups – could undermine the pursuit of herd immunity against COVID-19 in the United Kingdom. At the same time, the UK Joint Committee on Vaccination and Immunization (JVCI) indicated that it will not facilitate the choice between available COVID-19 vaccines. This paper reflects upon lessons from the introduction of the UK’s combined Measles, Mumps and Rubella (MMR) vaccine strategy of the 1980s when (...) Member of Parliament Miss Julie Kirkbride argued that had parents been allowed to choose between vaccine variants, then the crisis of low herd immunity – and subsequent outbreaks – could have been avoided. This paper explores this argument, as applied to the COVID-19 vaccination strategy, by considering how three key elements of informed consent – disclosure of risk, benefit, and reasonable alternatives – may be employed to tackle vaccine hesitancy and build vaccine confidence.

“Don’t think, but look!” (Wittgenstein 2009: § 66). This insistient advice has served as methodological inspiration for several influential thinkers in the broad range of ‘empirically informed’ philosophy, which has flourished over the last decades. There is, however, a worrisome tension between Wittgenstein’s work and these turns to practices, history, science, field work, and everyday life: Wittgenstein is in general doing something different from what the thinkers who claim to be inspired by him are doing. An argument for the legitimacy (...) of the move from Wittgenstein to empirically informed philosophy is so far missing in the literature. This article shows how this move can be justifiable within a Wittgensteinian frame, philosophically beneficial, and at times even necessary. (shrink)
