This essay is a sustained attempt to bring new light to some of the perennial problems in philosophy of mind surrounding phenomenal consciousness and introspection through developing an account of sensory and phenomenal concepts. Building on the information-theoretic framework of Dretske (1981), we present an informational psychosemantics as it applies to what we call sensory concepts, concepts that apply, roughly, to so-called secondary qualities of objects. We show that these concepts have a special informational character and semantic structure that closely (...) tie them to the brain states realizing conscious qualitative experiences. We then develop an account of introspection which exploits this special nature of sensory concepts. The result is a new class of concepts, which, following recent terminology, we call phenomenal concepts: these concepts refer to phenomenal experience itself and are the vehicles used in introspection. On our account, the connection between sensory and phenomenal concepts is very tight: it consists in different semantic uses of the same cognitive structures underlying the sensory concepts, such as the concept of red. Contrary to widespread opinion, we show that information theory contains all the resources to satisfy internalist intuitions about phenomenal consciousness, while not offending externalist ones. A consequence of this account is that it explains and predicts the so-called conceivability arguments against physicalism on the basis of the special nature of sensory and phenomenal concepts. Thus we not only show why physicalism is not threatened by such arguments, but also demonstrate its strength in virtue of its ability to predict and explain away such arguments in a principled way. However, we take the main contribution of this work to be what it provides in addition to a response to those conceivability arguments, namely, a substantive account of the interface between sensory and conceptual systems and the mechanisms of introspection as based on the special nature of the information flow between them.

The way physics and other parts of science work can be explained in the framework of radical constructivism. However, this constructivist view itself shows that a uniquily accepted epistemology, constructivism or any other, would not be an advantage for the developmentof science. Unlike physics some parts of science successfully use constructivist concepts inside their theories. Because this is the case particularly in learning theory, constructivist ideas can help to improve physics teaching.

Studies of perception have focussed on sensation, though more recently the perception of action has, once more, become the subject of investigation. These studies have looked at acute experimental situations. The present paper discusses the subjective experience of those with either clinical syndromes of loss of movement or sensation (spinal cord injury, sensory neuronopathy syndrome or motor stroke), or with experimental paralysis or sensory loss. The differing phenomenology of these is explored and their effects on intention and agency discussed. It (...) is shown that sensory loss can have effects on the focussing of motor command and that for some a sense of agency can return despite paralysis. (shrink)

One of the most striking manifestations of schizophrenia is thought insertion. People suffering from this delusion believe they are not the author of thoughts which they nevertheless own as experiences. It seems that a person’s sense of agency and their sense of the boundary between mind and world can come apart. Schizophrenia thus vividly demonstrates that self awareness is a complex construction of the brain. This point is widely appreciated. What is not so widely appreciated is how radically schizophrenia challenges (...) our assumptions about the nature of the self. Most theorists endorse the traditional doctrine of the unity of consciousness, according to which a normal human brain generates a single consciousness at any instant in time. In this paper we argue that phenomenal consciousness at each instant is actually a multiplicity: an aggregate of phenomenal elements, each of which is the product of a distinct consciousness-making mechanism in the brain. We then consider how certain aspects of self might emerge from this manifold substrate, and speculate about the origin of thought insertion. (shrink)

I defend Frank Jackson's knowledge argument against physicalism in the philosophy of mind from a criticism that has been advanced by Laurence Nemirow and David Lewis. According to their criticism, what Mary lacked when she was in her black and white room was a set of abilities; she did not know how to recognize or imagine certain types of experience from a first-person perspective. Her subsequent discovery of what it is like to experience redness amounts to no more than her (...) acquisition of these abilities. The physicalist can admit this, since it does not commit one to the view that there are any facts of which Mary was ignorant . I argue against this view, on the grounds that the knowledge of what an experience is like cannot be equated with the possession of any set of abilities. (shrink)

A common view about the phenomenology of episodic remembering has it that when we remember a perceptual experience, we can relive or re-experience many of its features, but not its characteristic presence. In this paper, we challenge this common view. We first say that presence in perception divides into temporal and locative presence, with locative having two sides, an objective and a subjective one. While we agree with the common view that temporal and objective locative presence cannot be relived in (...) remembering, we argue that subjective locative presence – the feeling of being immersed in a certain scene – can be so. Our argument for this claim starts by determining independently the underpinning mechanisms of subjective locative presence in quasi-perceptual imagination. These mechanisms are self-projection, imaginative pretence, and attentional focus. We then proceed to establish that they have been found to underpin conscious states of episodic remembering too. We conclude that episodic remembering can bring us to relive the subjective locative presence characteristic of a perceptual experience, and that the common view is mistaken. Our view – ‘mnemonic immersivism’ – has important consequences regarding the relationships between memory and imagination and the phenomenology of episodic remembering. (shrink)

In recent philosophy of science there has been much discussion of both pluralism, which embraces scientific terms with multiple meanings, and eliminativism, which rejects such terms. Some recent work focuses on the conditions that legitimize pluralism over eliminativism – the conditions under which such terms are acceptable. Often, this is understood as a matter of encouraging effective communication – the danger of these terms is thought to be equivocation, while the advantage is thought to be the fulfilment of ‘bridging roles’ (...) that facilitate communication between different scientists and specialisms. These theories are geared towards regulating communication between scientists qua scientists. However, this overlooks an important class of harmful equivocation that involves miscommunication between scientists and nonscientists, such as the public or policymakers. To make my case, I use the example of theory of mind, also known as ‘mindreading’ and ‘mentalizing’, and broadly defined as the capacity to attribute mental states to oneself and others. I begin by showing that ‘theory of mind’ has multiple meanings, before showing that this has resulted in harmful equivocations of a sort and in a way not accounted for by previous theories of pluralism and eliminativism.

The aim of this chapter is to shed new light on the question of what newly sighted subjects are capable of seeing on the basis of previous experience with mind- independent, external objects and their properties through touch alone. This question is also known as "Molyneux’s question." Much of the empirically driven debate surrounding this question has been centered on the nature of the representational content of the subjects' visual experiences. It has generally been assumed that the meaning of "seeing" (...) deployed in these disputes is more or less clear and unproblematic, and therefore requires no analysis or clarification. In this chapter, we wish to challenge this assumption. We argue that getting clear on the meaning of "seeing" is the only feasible way to determine whether the empirical attempts to answer Molyneux’s question accurately capture what newly sighted subjects are in fact capable of seeing. Specifically, we show that the dominant interpretations of the empirical results from a recent study (Held et al., 2011) fail to take into account that seeing can be not only purely visual but also epistemic in that it requires background knowledge (such as what an object with a particular viewpoint-independent shape looks like from a particular perspective).

Human consciousness is a phenomenon that occurs not only in the brain but also in an external network, a symbolic system. This symbolic system is defined as an exocerebrum. The exocerebrum is a system of artificial cultural prostheses that substitute functions the brain cannot carry out through exclusively biological means. The exocerebrum is a symbolic system that substitutes the cerebral circuits that are incapable by themselves of completing functions that are characteristic of human mental behavior. The brain is not capable (...) of processing symbols without the help of an external system essentially made up of speech, symbols, the non-discursive forms of communication, and the exterior artificial memories. We are in the presence of a continual spectrum, one in which there is no need to draw a dividing line between the brain and the exocerebrum, between the neuronal circuits and the cultural prostheses.

In recent years, philosophers have looked to empirical findings about psychopaths to help determine whether moral agency is underwritten by reason, or by some affective capacity, such as empathy. Since one of psychopaths’ most glaring deficits is a lack of empathy, and they are widely considered to be amoral, psychopaths are often taken as a test case for the hypothesis that empathy is necessary for moral agency. However, people with autism also lack empathy, so it is reasonable to think that (...) any empirically-informed attempt to answer the question of whether empathy is necessary for moral agency should give due attention to autism as well as psychopathy. Jeanette Kennett’s thought-provoking paper ‘Autism, Empathy and Moral Agency’ (2002) is an early and arguably the most notable example of such an attempt. Kennett argues that although autistic people and psychopaths both lack empathy, autistic people possess a ‘reverence for reason’ that enables them to become capable moral agents. By contrast, psychopaths lack this rational capacity, and it is this defect of reason rather than an empathic impairment that explains why they are amoral. Kennett thus concludes that empathy is not necessary for moral agency. In this chapter, I challenge Kennett’s argument. First, I review the empirical evidence in order to demonstrate that there is a component of empathy called affective empathy that is impaired in psychopaths but largely preserved in autistics. As such, the claim that psychopaths and autistics share a common lack of empathy is unjustified. Second, I challenge Kennett’s claim that empathy plays no role in explaining the moral difference between psychopaths and autistics. Instead, I contend that the intact affective empathy of autistic people is a crucial component of their capacity to act from reverence for reason. (shrink)

In this paper, I critically assess the enactive account of visual perception recently defended by Alva Noë (2004). I argue inter alia that the enactive account falsely identifies an object’s apparent shape with its 2D perspectival shape; that it mistakenly assimilates visual shape perception and volumetric object recognition; and that it seriously misrepresents the constitutive role of bodily action in visual awareness. I argue further that noticing an object’s perspectival shape involves a hybrid experience combining both perceptual and imaginative elements—an (...) act of what I call ‘make‐perceive’. (shrink)

Social cognition researchers have become increasingly interested in the ways that behavioral, physiological, and neural coupling facilitate social interaction and interpersonal understanding. We distinguish two ways of conceptualizing the role of such coupling processes in social cognition: strong and moderate interactionism. According to strong interactionism (SI), low-level coupling processes are alternatives to higher-level individual cognitive processes; the former at least sometimes render the latter superfluous. Moderate interactionism (MI) on the other hand, is an integrative approach. Its guiding assumption is that (...) higher-level cognitive processes are likely to have been shaped by the need to coordinate, modulate, and extract information from low-level coupling processes. In this paper, we present a case study on Möbius Syndrome (MS) in order to contrast SI and MI. We show how MS—a form of congenital bilateral facial paralysis—can be a fruitful source of insight for research exploring the relation between high-level cognition and low-level coupling. Lacking a capacity for facial expression, individuals with MS are deprived of a primary channel for gestural coupling. According to SI, they lack an essential enabling feature for social interaction and interpersonal understanding more generally and thus ought to exhibit severe deficits in these areas. We challenge SI’s prediction and show how MS cases offer compelling reasons for instead adopting MI’s pluralistic model of social interaction and interpersonal understanding. We conclude that investigations of coupling processes within social interaction should inform rather than marginalize or eliminate investigation of higher-level individual cognition. (shrink)

How the Body Shapes the Mind is an interdisciplinary work that addresses philosophical questions by appealing to evidence found in experimental psychology, neuroscience, studies of pathologies, and developmental psychology. There is a growing consensus across these disciplines that the contribution of embodiment to cognition is inescapable. Because this insight has been developed across a variety of disciplines, however, there is still a need to develop a common vocabulary that is capable of integrating discussions of brain mechanisms in neuroscience, behavioural expressions (...) in psychology, design concerns in artificial intelligence and robotics, and debates about embodied experience in the phenomenology and philosophy of mind. Shaun Gallagher's book aims to contribute to the formulation of that common vocabulary and to develop a conceptual framework that will avoid both the overly reductionistic approaches that explain everything in terms of bottom-up neuronal mechanisms, and inflationistic approaches that explain everything in terms of Cartesian, top-down cognitive states. Gallagher pursues two basic sets of questions. The first set consists of questions about the phenomenal aspects of the structure of experience, and specifically the relatively regular and constant features that we find in the content of our experience. If throughout conscious experience there is a constant reference to one's own body, even if this is a recessive or marginal awareness, then that reference constitutes a structural feature of the phenomenal field of consciousness, part of a framework that is likely to determine or influence all other aspects of experience. The second set of questions concerns aspects of the structure of experience that are more hidden, those that may be more difficult to get at because they happen before we know it. They do not normally enter into the content of experience in an explicit way, and are often inaccessible to reflective consciousness. To what extent, and in what ways, are consciousness and cognitive processes, which include experiences related to perception, memory, imagination, belief, judgement, and so forth, shaped or structured by the fact that they are embodied in this way?

This chapter offers an overview of methodological issues within science education research and considers the extent to which this area of scholarship can be understood to (actually and potentially) be scientific. The chapter considers the nature of education and educational research, how methodological issues are discussed in educational research and the range of major methodological strategies commonly used. It is suggested that the way research is discussed, undertaken and reported seems quite different in science education from research in the natural (...) sciences as science education studies are informed by quite diverse paradigmatic commitments. The nature of educational phenomena is such that it is unlikely that science education could adopt the kind of disciplinary matrix that can guide researchers in the natural sciences (by allowing much methodological thinking to be implicit and taken for granted within a field). However, Lakatos’s ‘scientific research programmes’ (SRP) offer a view of research traditions that can encompass social science research. From this perspective, it is possible for progressive SRP to operate in science education. (shrink)

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

We humans have a formidable armamentarium of social display behaviours, including song-and-dance, the visual arts, and role-play. Of these, role-play is probably the crucial adaptation which makes us most different from other apes. Human childhood, a sheltered period of ‘extended irresponsibility’, allows us to develop our powers of make-believe and role-play, prerequisites for human cooperation, culture, and reflective consciousness. Social mirror theory, originating with Dilthey, Baldwin, Cooley and Mead, holds that there cannot be mirrors in the mind without mirrors in (...) society. I will present evidence from the social and behavioural sciences to argue that self-awareness depends on social mirrors and shared experiential worlds. The dependence of reflectivity on shared experience requires some reframing of the ‘hard problem’, and suggests a non-trivial answer to the zombie question. (shrink)

This paper examines what it is for a condition to be a disease. It falls into two sections. In the first I examine the best existing account of disease (as proposed by Christopher Boorse) and argue that it must be rejected. In the second I outline a more acceptable account of disease. According to this account, by disease we mean a condition that it is a bad thing to have, that is such that we consider the afflicted person to have (...) been unlucky, and that can potentially be medically treated. All three criteria must be fulfilled for a condition to be a disease. The criterion that for a condition to be a disease it must be a bad thing is required to distinguish the biologically different from the diseased. The claim that the sufferer must be unlucky is needed to distinguish diseases from conditions that are unpleasant but normal, for example teething. Finally, the claim that for a condition to be a disease it must be potentially medically treatable is needed to distinguish diseases from other types of misfortune, for example economic problems and legal problems.

Economic models of addiction are choice-based. These models push the choice paradigm too far by modeling addiction as rational, normative behavior. Heyman's target article provides a sensible alternative to this economic approach by emphasizing that addiction is characterized by ambivalence and a perceived loss of self control. However, matching may not be a satisfactory platform on which to build this alternative model. Matching experiments do not provide evidence of ambivalence or perceived loss of self control.

Heyman makes a convincing case that a melioration choice strategy is sufficient to produce addictive behavior. But given a plethora of addiction theories, the question is whether melioration theory is superior to rivals more sophisticated than a simple disease model or operant conditioning account. Heyman offers little direct evidence that melioration actually causes the addictions we observe.

Numerous individual differences determine the effectiveness of the multiple external reinforcement contingencies that control drug seeking behavior. Differences in the capacity to frame reinforcement and also the toxic effects of drugs modulate susceptibility to addiction. As a result, not all individuals are at the same degree of risk for addiction.

Research findings on addiction are contradictory. According to biographical records and widely used diagnostic manuals, addicts use drugs compulsively, meaning that drug use is out of control and independent of its aversive consequences. This account is supported by studies that show significant heritabilities for alcoholism and other addictions and by laboratory experiments in which repeated administration of addictive drugs caused changes in neural substrates associated with reward. Epidemiological and experimental data, however, show that the consequences of drug consumption can significantly (...) modify drug intake in addicts. The disease model can account for the compulsive features of addiction, but not occasions in which price and punishment reduced drug consumption in addicts. Conversely, learning models of addiction can account for the influence of price and punishment, but not compulsive drug taking. The occasion for this target article is that recent developments in behavioral choice theory resolve the apparent contradictions in the addiction literature. The basic argument includes the following four statements: First, repeated consumption of an addictive drug decreases its future value and the future value of competing activities. Second, the frequency of an activity is a function of its relative (not absolute) value. This implies that an activity that reduces the values of competing behaviors can increase in frequency even if its own value also declines. Third, a recent experiment (Heyman & Tanz 1995) shows that the effective reinforcement contingencies are relative to a frame of reference, and this frame of reference can change so as to favor optimal or suboptimal choice. Fourth, if the frame of reference is local, reinforcement contingencies will favor excessive drug use, but if the frame of reference is global, the reinforcement contingencies will favor controlled drug use. The transition from a global to a local frame of reference explains relapse and other compulsive features of addiction. (shrink)

This paper provides a brief overview and critique of the dominant objectivist understanding and use of illness narrative in Enlightenment (scientific) medicine and ethics, as well as several revisionist accounts, which reflect the evolution of this approach. In light of certain limitations and difficulties endemic in the objectivist understanding of illness narrative, an alternative phronesis approach to medical ethics influenced by Charles Taylor’s account of the interpretive nature of human agency and language is examined. To this end, the account of (...) interpretive medical responsibility previously described by Schultz and Carnevale as "clinical phronesis" (based upon Taylor’s notion of "strong" or "radical evaluation") is reviewed and expanded. The thesis of this paper is that illness narrative has the ability to benefit patients as well as the potential to cause harm or iatrogenic effects. This benefit or harm is contingent upon how the story is told and understood. Consequently, these tales are not simply "nice stories," cathartic gestures, or mere supplements to scientific procedures and decision making, as suggested by the objectivist approach. Rather, they open the agent to meanings that provide a context for explanation and evaluation of illness episodes and therapeutic activities. This understanding provides indicators (guides) for right action. Hence, medical responsibility as clinical phronesis involves, first, the patient and provider’s coformulation and cointerpretation of what is going on in the patient’s illness narrative, and second, the patient and provider’s response to interpretation of the facts of illness and what they signify–not simply a response to the brute facts of illness, alone. The appeal to medical responsibility as clinical phronesis thus underscores the importance of getting the patient’s story of illness right. It is anticipated that further elaboration concerning the idea of clinical phronesis as interpretive illness narrative will provide a new foundation for medical ethics and decision making. (shrink)

This essay defends virtue reliabilism against a line of argument put forward by Duncan Pritchard. In the process, it discusses (1) the motivations for virtue reliabilism, (2) some analogies between epistemic virtue and moral virtue, and (3) the relation between virtue (epistemic and otherwise) and luck (epistemic and otherwise). It argues that considerations about virtue and luck suggest a solution to Gettier problems from the perspective of a virtue theory.

Considering the close relation between language and theory of mind in development and their tight connection in social behavior, it is no big leap to claim that the two capacities have been related in evolution as well. But what is the exact relation between them? This paper attempts to clear a path toward an answer. I consider several possible relations between the two faculties, bring conceptual arguments and empirical evidence to bear on them, and end up arguing for a version (...) of co-evolution. To model this co-evolution, we must distinguish between different stages or levels of language and theory of mind, which fueled each other’s evolution in a protracted escalation process. (shrink)

The binding problem is frequently discussed in consciousness research. However, it is by no means clear what the problem is supposed to be and how exactly it relates to consciousness. In the present paper the nature of the binding problem is clarified by distinguishing between different formulations of the problem. Some of them make no mention of consciousness, whereas others are directly related to aspects of phenomenal experience. Certain formulations of the binding problem are closely connected to the classical philosophical (...) problem of the unity of consciousness and the currently fashionable search for the neural correlates of consciousness. Nonetheless, only a part of the current empirical research on binding is directly relevant to the study of consciousness. The main message of the present paper is that the science of consciousness needs to establish a clear theoretical view of the relation between binding and consciousness and to encourage further empirical work that builds on such a theoretical foundation.

Philosophers tend to assume that we have excellent knowledge of our own current conscious experience or 'phenomenology'. I argue that our knowledge of one aspect of our experience, the experience of visual imagery, is actually rather poor. Precedent for this position is found among the introspective psychologists of the late nineteenth and early twentieth centuries. Two main arguments are advanced toward the conclusion that our knowledge of our own imagery is poor. First, the reader is asked to form a visual (...) image, and it is expected that answering questions about certain basic features of that experience will be difficult. If so, it seems reasonable to suppose that people could be mistaken about those basic features of their own imagery. Second, it is observed that although people give widely variable reports about their own experiences of visual imagery, differences in report do not systematically correlate with differences on tests of skills that psychologists have often supposed to require visual imagery, such as mental rotation, visual creativity, and visual memory.

In contrast to mainstream accounts which explain the aesthetic experience of people with autism spectrum disorder (ASD) in terms of cognitive abilities, this paper suggests as an alternative explanation the “emotional abilities approach”. We present an example of a person with ASD who is able to exercise a variety of emotional abilities in aesthetic contexts but who has difficulties exhibiting their equivalents in interpersonal relations. Using an autobiographical account, we demonstrate first that there is at least one precedent where a (...) person with ASD can exercise a series of emotional abilities when engaging with art works. Second, we offer also an explanation about why aesthetic contexts might enable this person to exercise emotional abilities which in interpersonal contexts seem to be blocked. (shrink)

The volume analyses and develops David Makinson’s efforts to make classical logic useful outside its most obvious application areas. The book contains chapters that analyse, appraise, or reshape Makinson’s work and chapters that develop themes emerging from his contributions. These are grouped into major areas to which Makinsons has made highly influential contributions and the volume in its entirety is divided into four sections, each devoted to a particular area of logic: belief change, uncertain reasoning, normative systems and the resources (...) of classical logic. Among the contributions included in the volume, one chapter focuses on the “inferential preferential method”, i.e. the combined use of classical logic and mechanisms of preference and choice and provides examples from Makinson’s work in non-monotonic and defeasible reasoning and belief revision. One chapter offers a short autobiography by Makinson which details his discovery of modern logic, his travels across continents and reveals his intellectual encounters and inspirations. The chapter also contains an unusually explicit statement on his views on the role of logic in philosophy. (shrink)

RésuméFred Dretske a développé, à titre de composante de sa théorie de la conscience, une théorie de I'introspection. Celle-ciprésente une plausibilityé indépendante, elle résiste à des objections qui affectent nombre d'autres théories et elle suggère des liens très féconds dans plusieurs domaines de la science cognitive. La version qu'en donne Dretske est restreinte à la connaissance introspective des états perceptuels. Mon objectif ici est d'étendre la théorie à tous les états mentaux. Le mécanisme qui est fondamental dans cette approche est (...) celui de la «conscience déplacée», c'est-à-dire le fait d'en venir à connaître quelque chose via l'expérience consciente que nous avons de quelque chose d'autre. Nous atteignons la connaissance introspective par l'application à notre propre expérience consciente du monde (et de nos corps) de la connaissance que nous avons de ce qui est de l'ordre du mental.

Any theoretician constructing a serious model of consciousness should carefully assess the details of empirical data generated in the neurosciences and psychology. A failure to account for those details may cast doubt on the adequacy of that model. This paper presents a case in point. Dennett and Kinsbourne's (Dennett, D., & Kinsbourne, M. (1992). Time and the observer: The where and when of consciousness in the brain. Behavioral and Brain Sciences, 15, 183-243) assault on the materialist version of the Cartesian (...) Theater model of the mind relies significantly on the superiority of their Multiple Drafts model of consciousness as an explanation of the phenomenon of metacontrast. However, their description of metacontrast is, in important ways, inadequate. The result is that their explanation of how the Multiple Drafts model handles this phenomenon fails to account for the actual data. In this paper I offer a more complete description of metacontrast, show how Dennett and Kinsbourne's explanation fails, and argue that there are good theoretical reasons for choosing the so-called Stalinesque model over the so-called Orwellian model.

Heyman's target article is an analytical tour de force, but it makes too hard a distinction between voluntary and driven behavior. It is more fruitful to think about brain and behavior as shifting, interacting “agents,” represented by multiple neural circuits. This has the virtue of better connecting behavioral analysis with wet neuroscience.

For use in applied settings, the melioration model will need to incorporate changes in the shapes of local value functions over time, treat current value as a continuous function of time since previous choices, and take into account discounting of the effects of current behavior on future value. The policy implications of the model for regulating drugs are limited.

Addictive behavior has never seemed rational because it persists in spite of drastic aversive consequences. This is a particular problem for models of addiction such as operant psychology which hold that behavior is controlled by its consequences. Inspite of claims to the contrary, Heymans target article illustrates how operant psychology resolves this contradiction. By using the matching law, Heyman suggests a mechanism that explains why delayed aversive events may not control behavior, and a conceptual framework in which we can understand (...) successful therapies. (shrink)

Heyman's target article makes a strong case for a behavioral approach to addiction, yet some important assumptions require justification, and promising behavioral alternatives to the author's melioration approach should be considered. In particular, the behavioral economic approach to addiction appears well developed and comprehensive. How does the melioration approach complement or improve on a behavioral economic account?

I address a number of issues related to building an autonomous social robot. I review different approaches to social cognition and ask how these different approaches may inform the design of social robots. I argue that regardless of which theoretical approach to social cognition one favors, instantiating that approach in a workable robot will involve designing that robot on enactive principles.

It is commonplace for both philosophers and cognitive scientists to express their allegiance to the "unity of consciousness". This is the claim that a subject’s phenomenal consciousness, at any one moment in time, is a single thing. This view has had a major influence on computational theories of consciousness. In particular, what we call single-track theories dominate the literature, theories which contend that our conscious experience is the result of a single consciousness-making process or mechanism in the brain. We argue (...) that the orthodox view is quite wrong: phenomenal experience is not a unity, in the sense of being a single thing at each instant. It is a multiplicity, an aggregate of phenomenal elements, each of which is the product of a distinct consciousness-making mechanism in the brain. Consequently, cognitive science is in need of a multi-track theory of consciousness; a computational model that acknowledges both the manifold nature of experience, and its distributed neural basis.

Humans are capable of understanding an incredible variety of actions performed by other humans. Even though these range from primary biological actions, like eating and fleeing, to acts in parliament or in poetry, humans generally can make sense of each other’s actions. Action understanding is the cognitive ability to make sense of another person’s action by integrating perceptual information about the behavior with knowledge about the immediate and sociocultural contexts of the action, understanding of relevant meanings and one’s own experience. (...) Given the importance of action understanding in every domain of human life and society, and in light of the complexities that surround it, a comprehensive scientific understanding of this capacity is needed. Scholars are increasingly dissatisfied with monodisciplinary approaches to understanding human action, like when an action is interpreted only in sociocultural terms while overlooking cognitive constraints, or when an action is understood in biological terms while neglecting its psychological impact on the agent. Recent interdisciplinary endeavors demonstrate how an interdisciplinary approach is possible when investigating complex functions like action understanding. Ever more insight is gained in the mutual influences between biological, cognitive and sociocultural processes that together contribute to action and action understanding. The purpose of this chapter is to describe how a ‘mechanistic explanation’, or a ‘mechanism-based explanation’ of action understanding provides a theoretical framework for integrating various and often conflicting disciplinary insights. By applying the heuristics of ‘definition’, ‘decomposition’ and ‘localization’, researchers can determine the phenomenon that they collaboratively investigate while at the same time dividing this task into smaller component tasks of which the results must eventually be put together. Some researchers, for example, can apply a hermeneutic approach to the sociocultural environment in which action understanding takes place, while others aim to specify the cognitive processes or the neuro-electrical pathways that are activated under those conditions. After having presented a step-by-step analysis of an interdisciplinary investigation of action understanding by way of developing a mechanistic explanation the chapter closes with some suggestions for testing its result and mentions some limitations of this approach.

It is argued that the emotional feeling comprises the following two emotional qualia. (1) A nucleus feeling or primary emotional quale, which is the phenomenological counterpart of the end product of appraisal by the central nervous system. (2) The experience of being urged to emotion-related reflection or secondary emotional quale, which is the phenomenological counterpart of the brain's decision to inhibit pre-programmed emotional behaviour, and to initiate emotion-related reflections. Different brain modules regulate these two qualia, and thus each can be (...) experienced independently of the other. The primary emotional quale is related to activation of the amygdala, it is emotion specific, and neutral with respect to affect. The secondary emotional quale is related to activation of the orbito-prefrontal cortex (O-PFC), and includes affective aspects.It is argued that emotional behaviour is regulated by the following three neural mechanisms, two of which two are directly related to the two qualia. (1) An evolutionary ancient system (amygdala-system), which comprises the amygdalae and subcortical nuclei, and which activates pre-programmed emotional behaviour. (2) An evolutionary recent system (PFC-system), comprising the prefrontal cortex, which inhibits pre-programmed emotional behaviour, activates emotional reflection, generates and evaluates behavioural alternatives. In contrast to the pre-programmed behaviour, the behavioural alternatives are more likely to serve long-term goals. (3) A default mechanism, which gives rise to default (i.e., “just do something”) behaviour. The first two systems are mutually competitive, while the third mechanism takes over if either the competition between the first two mechanisms, or the decision process of the PFC-system, takes too long. This default mechanism involves the function of the medial-prefrontal cortex (M-PFC). (shrink)

This paper offers an inconsistent model of motion perception. It was prompted by work on inconsistent motion due to Hegel and, following him, Priest. But the paper skirts Hegel's full scale idealism, by proposing that the inconsistency is with the cognitive contents of motion perception. The paper draws on work in the psychology of perception, and in the theory of inconsistency. I begin by noting the prima facie argument that temporal change threatens inconsistency, and canvassing ways in which this might (...) be avoided. The orthodox reply to the prima facie argument is that one and the same thing can have different incompatible properties at different times. This is plausible when applied to motion in the physical world. However, applied to cognition, it can be seen that the phenomenon of phi or beta, combined with the mechanism of a Reichardt detector, lends support to one key step in the prima facie argument, namely re-identification over time. The inconsistency of the model is then seen to follow from application of the Fade Principle. Advantages of the model are stressed: including a simple explanation of the debilitating condition of akinetopsia, that is, motion blindness; and a suggestion as to how to account for the “moving now.”.

: Sociologists of Scientific Knowledge sometimes claim to study scientists belonging to other forms of life. This claim causes difficulties, as traditionally Wittgensteinians have taken it to be the case that other forms of life are incomprehensible to us. This paper examines whether, and how, sociologists might gain understanding of another form of life, and whether, and how, this understanding might be passed on to readers. I argue that most techniques proposed for gaining and passing on understanding are inadequate, but (...) I end by describing a method that might work. (shrink)

In philosophy, the last thirty years or so has seen a split between 'simulation theorists' and 'theory-theorists', with a number of variations on each side. In general, simulation theorists favour the idea that our knowledge of others is based on using ourselves as a working model of what complex psychological creatures are like. Theory-theorists claim that our knowledge of complex psychological creatures, including ourselves, is theoretical in character and so more like our knowledge of the world in general. The body (...) of this paper is divided into three parts. In Part I, I introduce the 'contrastive case' of autism. Autism is a developmental disorder that has recently become the focus of sustained philosophical and psychological attention because of the selective way in which it affects individuals' social capacities. Theory-theorists argue that autistic children's unique profile of assets and deficits is most fruitfully explained by their inability to develop and deploy a theory of mind. After considering the strengths of this hypothesis, I claim theory-theorists face two unresolved difficulties: explaining why high-functioning autistics who develop some theory of mind capacities still fail to engage in normal psychological knowing; and explaining why autistics are generally as unknowable to us in the privileged sense of normal psychological knowing as we are to them. In Part II, I provide the theoretical framework for addressing these challenges by developing an account of normal psychological knowing as psycho-practical expertise. In Part III, I return to the problem of autism, showing how this psycho-practical approach to normal psychological knowing may further suggest how to encompass various aspects of the disorder that tend to be ignored under the prevailing theory-theory approach.

The explanatory gap and theknowledge argument are rooted in the conflationof propositional and phenomenal knowledge. Thebasic knowledge argument is based on theconsideration that ``physical information'' aboutthe nervous system is unable to provide theknowledge of a ``color experience'' . The implication is that physicalism isincomplete or false because it leaves somethingunexplained. The problem with Jackson'sargument is that physical information has theform of highly symbolic propositional knowledgewhereas phenomenal knowledge consists in innateneurophysiological processes. In addition totheir fundamental epistemological differences,clinical, anatomical, pathological and brainimaging (...) studies demonstrate that phenomenal andpropositional knowledge are fundamentallydifferent neurobiological processes. Propositional knowledge is phylogeneticallynew, highly symbolic, culturally acquired,exclusively human and expressible in differentnatural and artificial languages. By contrast,phenomenal knowledge consists inqualitative experiences and phenomenal conceptsthat provide an internal, language-independentreference to the properties of objects and theneeds of the organism. Language andpropositional knowledge are exclusively humanattributes implemented in specific regions ofthe dominant hemisphere. This contrastssharply with the phylogenicallysensory areas that are common to animals andhumans, which implement qualitativeexperiences. Experiences are hard-wiredneurobiological processes that can neither betransmitted nor re-created through thesymbolism of propositions. Thus, I concludethat the fallacy in the explanatory gap and inthe knowledge argument is a fallacy ofequivocation that results from ignoringfundamental neurobiological differences betweenphenomenal and propositional knowledge.

Recent years have seen enticing empirical approaches to solving the epistemological problem of the theory-ladenness of observation. I group these approaches in two categories according to their method of choice: testing and refereeing. I argue that none deliver what friends of theory-neutrality want them to. Testing does not work because both evidence from cognitive neuroscience and perceptual pluralism independently invalidate the existence of a common observation core. Refereeing does not work because it treats theory-ladenness as a kind of superficial, removable (...) bias. Even if such treatment is plausible, there is likely no method to ascertain that effects of this bias are not present. More importantly, evidence from cognitive neuroscience suggests that a deeper, likely irremovable kind of theory-ladenness lies within the perceptual modules. (shrink)

Modern belief revision theory is based to a large extent on partial meet contraction that was introduced in the seminal article by Carlos Alchourrón, Peter Gärdenfors, and David Makinson that appeared in 1985. In the same year, Alchourrón and Makinson published a significantly different approach to the same problem, called safe contraction. Since then, safe contraction has received much less attention than partial meet contraction. The present paper summarizes the current state of knowledge on safe contraction, provides some new results (...) and offers a list of unsolved problems that are in need of investigation. (shrink)

Heyman's analysis of addiction suggests that drug taking is irrational. The irrationality of drug taking, however, may depend on the acceptance of mainstream society's view of what is valuable. Consideration of the addict's viewpoint and cultural aspects of drug taking may be useful in trying to fathom the “rationality” of drug taking.

This paper is prompted by the charge that the prevailing Western paradigm of medical knowledge is essentially Cartesian. Hence, illness, disease, disability, etc. are said to be conceived of in Cartesian terms. The paper attempts to make use of the critique of Cartesianism in medicine developed by certain commentators, notably Leder (1992), in order to expose Cartesian commitments in conceptions of disability. The paper also attempts to sketch an alternative conception of disability — one partly inspired by the work of (...) Merleau-Ponty. In particular, three key Cartesian claims are identified and subjected to criticism. These are as follows: (a) The claim that the body is an object, (b) what is termed here ‘the modularity thesis’, and (c) the claim that the body cannot be constitutive of the self (i.e. since the soul/mind/brain is). In opposition to these claims, it is argued that the body is properly viewed as a subject; that there are neither purely mental, nor purely physical disabilities; and that selves are constituted, at least in part, by their bodies.
