Schizophrenia is a worldwide, prevalent disorder with a multifactorial but highly genetic aetiology. A constant prevalence rate in the face of reduced fecundity has caused some to argue that an evolutionary advantage exists in unaffected relatives. Here, I critique this adaptationist approach, and review – and find wanting – Crow's “speciation” hypothesis. In keeping with available biological and psychological evidence, I propose an alternative theory of the origins of this disorder. Schizophrenia is a disorder of the social brain, and it (...) exists as a costly trade-off in the evolution of complex social cognition. Paleoanthropological and comparative primate research suggests that hominids evolved complex cortical interconnectivity (in particular, frontotemporal and frontoparietal circuits) to regulate social cognition and the intellectual demands of group living. I suggest that the ontogenetic mechanism underlying this cerebral adaptation was sequential hypermorphosis and that it rendered the hominid brain vulnerable to genetic and environmental insults. I argue that changes in genes regulating the timing of neurodevelopment occurred prior to the migration of Homo sapiens out of Africa 100,000–150,000 years ago, giving rise to the schizotypal spectrum. While some individuals within this spectrum may have exhibited unusual creativity and iconoclasm, this phenotype was not necessarily adaptive in reproductive terms. However, because the disorder shared a common genetic basis with the evolving circuitry of the social brain, it persisted. Thus schizophrenia emerged as a costly trade-off in the evolution of complex social cognition. Key Words: cortical connectivity; evolution; heterochrony; metarepresentation; primates; psychiatry; schizophrenia; social brain; social cognition. (shrink)

Research seeking a scientific foundation for the theory of art appreciation has raised controversies at the intersection of the social and cognitive sciences. Though equally relevant to a scientific inquiry into art appreciation, psychological and historical approaches to art developed independently and lack a common core of theoretical principles. Historicists argue that psychological and brain sciences ignore the fact that artworks are artifacts produced and appreciated in the context of unique historical situations and artistic intentions. After revealing flaws in the (...) psychological approach, we introduce a psycho-historical framework for the science of art appreciation. This framework demonstrates that a science of art appreciation must investigate how appreciators process causal and historical information to classify and explain their psychological responses to art. Expanding on research about the cognition of artifacts, we identify three modes of appreciation: basic exposure to an artwork, the artistic design stance, and artistic understanding. The artistic design stance, a requisite for artistic understanding, is an attitude whereby appreciators develop their sensitivity to art-historical contexts by means of inquiries into the making, authorship, and functions of artworks. We defend and illustrate the psycho-historical framework with an analysis of existing studies on art appreciation in empirical aesthetics. Finally, we argue that the fluency theory of aesthetic pleasure can be amended to meet the requirements of the framework. We conclude that scientists can tackle fundamental questions about the nature and appreciation of art within the psycho-historical framework. (shrink)

This article compares the ability to track individuals lacking mental states with the ability to track intentional agents. It explains why reference to individuals raises the problem of explaining how cognitive agents track unique individuals and in what sense reference is based on procedures of perceptual-motor and epistemic tracking. We suggest applying the notion of singular-files from theories in perception and semantics to the problem of tracking intentional agents. In order to elucidate the nature of agent-files, three views of the (...) relation between object- and agent-tracking are distinguished: the Independence, Deflationary and Organism-Dependence Views. The correct view is argued to be the latter, which states that perceptual and epistemic tracking of a unique human organism requires tracking both its spatio-temporal object-properties and its agent-properties.

In our commentary we elaborate on Barresi & Moore's use of language as a tool. In particular, we highlight the importance of cognitive linguistic research with its emphasis on the relation between morpnosyntax and intentional schemes. We also speculate about how language itself might play a role in children's integration of first and third person knowledge.

The question of whether AI systems such as robots can or should be afforded moral agency or patiency is not one amenable either to discovery or simple reasoning, because we as societies constantly reconstruct our artefacts, including our ethical systems. Consequently, the place of AI systems in society is a matter of normative, not descriptive ethics. Here I start from a functionalist assumption, that ethics is the set of behaviour that maintains a society. This assumption allows me to exploit the (...) theoretical biology of sociality and autonomy to explain our moral intuitions. From this grounding I extend to consider possible ethics for maintaining either human- or of artefact-centred societies. I conclude that while constructing AI systems as either moral agents or patients is possible, neither is desirable. In particular, I argue that we are unlikely to construct a coherent ethics in which it it is ethical to afford AI moral subjectivity. We are therefore obliged not to build AI we are obliged to.

Daniel Kahneman was not the first to suggest that attention and effort are closely associated, but his 1973 book Attention and Effort, which claimed that attention can be identified with effort, cemented the association as a research paradigm in the cognitive sciences. Since then, the paradigm has rarely been questioned and appears to have set the research agenda so that it is self-reinforcing. In this article, we retrace Kahneman's argument to understand its strengths and weaknesses. The central notion of effort (...) is not clearly defined in the book, so we proceed by constructing the most secure inferences we can from Kahneman's argument regarding effort: it is cognitive, objective, metabolic expenditure, and it is attention. Continuing, we find from Kahneman's argument that effort-attention must be a special case of sympathetic dominance of the autonomic nervous system that is also an increase in metabolic activity in the brain that has crossed a threshold of magnitude. We then weigh this conception of effort against evidence in Kahneman's book and against more recent evidence, finding that it does not warrant the conclusion that effort can be equated with attention. In support of an alternative perspective, we briefly review diverse studies of behavior, physiology and neuroscience on attention and effort, including meditation and studies of the LC-NE system, where we find evidence for the following: 1) Attention seems to be associated not with the utilization of metabolic resources per se but with the readying of metabolic resources in the form of adaptive gain modulation. This occurs under sympathetic dominance and can be experienced as effortful. 2) Attention can also occur under parasympathetic dominance, in which case it is likely experienced as effortless.

Knowledge of one's own states of mind is one of the varieties of self-knowledge. Do any nonhuman animals have the capacity for this variety of self-knowledge? The question is open to empirical inquiry, which is most often conducted with primate subjects. Research with a bottlenose dolphin gives some evidence for the capacity in a nonprimate taxon. I describe the research and evaluate the metacognitive interpretation of the dolphin's behaviour. The research exhibits some of the difficulties attached to the task of (...) eliciting behaviour that both attracts a higher-order interpretation while also resisting deflationary, lower-order interpretations. Lloyd Morgan's Canon, which prohibits inflationary interpretations of animal behaviour, has influenced many animal psychologists. There is one defensible version of the Canon, the version that warns specifically against unnecessary intentional ascent. The Canon on this interpretation seems at first to tell against a metacognitive interpretation of the data collected in the dolphin study. However, the model of metacognition that is in play in the dolphin studies is a functional model, one that does not implicate intentional ascent. I explore some interpretations of the dolphin's behaviour as metacognitive, in this sense. While this species of metacognitive interpretation breaks the connection with the more familiar theory of mind research using animal subjects, the interpretation also points in an interesting way towards issues concerning consciousness in dolphins.

Patients may show a more-or-less complete deviation of the head and eyes towards the right (ipsilesional) side [that is, to the same side of egocentric space as the brain lesion responsible for their disorder]. If addressed by the examiner from the left (contralesional) side [the opposite side to their lesion], patients with severe extrapersonal neglect may fail to respond or may look for the speaker in the right side of the room, turning head and eyes more and more to the (...) right. Frequently these patients will not pick up food from the left half of the plate. Given a crossword puzzle, they may complete only the squares to the right. If walking is not prevented by hemiparesis, neglect patients may lose their bearings, since they do not make use of left sided cues. (shrink)

Looking back on the development of computer technology, particularly in the context of manufacturing, we can distinguish three big waves of technological exuberance with a wave length of roughly 30 years: In the first wave, during the 1950s, mainframe computers at that time were conceptualized as “electronic brains” and envisaged as central control unit of an “automatic factory”. Thirty years later, during the 1980s, knowledge-based systems in computer-integrated manufacturing were adored as the computational core of the “unmanned factory”. Both waves (...) dismally stranded on the contumacies of reality. Nevertheless, again thirty years later, we now experience the departure of the “smart factory” based on networks of “artificially intelligent” multi-agent or “cyber-physical systems”. From the very beginning, these technological exuberances rooted in mistaken metaphors describing the artifacts and, hence, in delusions about the true nature of computer systems. The behaviour of computers is, as computing science teaches us, strictly restrained to executing computable functions by means of algorithms, it thus neither resembles the performance of a brain as part of a complex sensitive living body nor is it in any meaningful sense “knowledgeable” or “intelligent”. When the delusion of being able to implement “smart factories”, despite the countless accomplishment failures before, gains momentum anew, it appears absolutely essential to reflect on underlying misconceptions.

Representationalists argue that phenomenal states are intentional states of a special kind. This paper offers an account of the kind of intentional state phenomenal states are: I argue that they are underived intentional states. This account of phenomenal states is equivalent to two theses: first, all possible phenomenal states are underived intentional states; second, all possible underived intentional states are phenomenal states. I clarify these claims and argue for each of them. I also address objections which touch on a range (...) of topics, including meaning holism and concept empiricism. I conclude with a brief discussion of the consequences of the proposed view for the project of naturalizing consciousness. (shrink)

Some current attempts to go beyond the narrow scope of rational choice theory (RCT) in the social sciences and the artificial reconstructions it sometimes provides focus on the arguments that people give to justify their beliefs and behaviors themselves. But the available argumentation theories are not constructed to fill this gap. This article argues that relevance theory, on the contrary, suggests interesting tracks. This provocative idea requires a rereading of Sperber and Wilson's theory. Actually, the authors do not explicitly support (...) RCT, and Sperber has even strongly criticized methodological individualism, which most of the time underlies RCT, in favor of infra-individualism. A key point of the argument presented here is to show that Sperber and Wilson do not firmly distinguish between infra-individualism and subintentionality. Only subintentionality is needed. Key Words: argumentation • rational choice • relevance theory • methodological individualism. (shrink)

A common deflationary tendency has emerged recently in both philosophical accounts and comparative animal studies concerned with how subjects understand the actions of others. The suggestion emerging from both arenas is that the default mechanism for understanding action involves only a sensitivity to the observable, behavioural (non-mental) features of a situation. This kind of ‘smart behaviour reading’ thus suggests that, typically, predicting or explaining the behaviour of conspecifics does not require seeing the other through the lens of mental state attribution. (...) This paper aims to explore and assess this deflationary move. In §1 I clarify what might be involved in a smart behaviour reading account via looking at some concrete examples. Then in §2 I critically assess the deflationary move, arguing that, at least in the human case, it would in fact be a mistake to assume that our default method of action understanding proceeds without appeal to mental state attribution. Finally in §3 I consider briefly how the positive view proposed here relates to discussions about standard two-system models of cognition. (shrink)

In the past decades, reductionism has dominated both research directions and funding policies in clinical psychology and psychiatry. The intense search for the biological basis of mental disorders, however, has not resulted in conclusive reductionist explanations of psychopathology. Recently, network models have been proposed as an alternative framework for the analysis of mental disorders, in which mental disorders arise from the causal interplay between symptoms. In this target article, we show that this conceptualization can help explain why reductionist approaches in (...) psychiatry and clinical psychology are on the wrong track. First, symptom networks preclude the identification of a common cause of symptomatology with a neurobiological condition; in symptom networks, there is no such common cause. Second, symptom network relations depend on the content of mental states and, as such, feature intentionality. Third, the strength of network relations is highly likely to depend partially on cultural and historical contexts as well as external mechanisms in the environment. Taken together, these properties suggest that, if mental disorders are indeed networks of causally related symptoms, reductionist accounts cannot achieve the level of success associated with reductionist disease models in modern medicine. As an alternative strategy, we propose to interpret network structures in terms of D. C. Dennett's (1987) notion ofreal patterns, and suggest that, instead of being reducible to a biological basis, mental disorders feature biological and psychological factors that are deeply intertwined in feedback loops. This suggests that neither psychological nor biological levels can claim causal or explanatory priority, and that a holistic research strategy is necessary for progress in the study of mental disorders.

The theory of mind (ToM) framework has been criticised by emerging alternative accounts. Each alternative begins with the accusation that ToM's validity as a research paradigm rests on the assumption of the ‘unobservability’ of other minds. We argue that the critics' discussion of the unobservability assumption (UA) targets a straw man. We discuss metaphysical, phenomenological, epistemological, and psychological readings of UA and demonstrate that it is not the case that ToM assumes the metaphysical, phenomenological, or epistemological claims. However, ToM supports (...) the psychological UA as a claim about cognitive processes responsible for mindreading. The latter can be interpreted as a claim that (a) neither the other's ‘mindedness’ in general nor the other's particular mental states are observable (i.e. apprehended perceptually); (b) particular mental states are unobservable, whereas some aspects indicative of ‘mindedness’ are observable; (c) some mental states are unobservable but some are also observable. Whereas the critics tend to attribute (a) to ToM, most ToM accounts actually take positions (b) or (c). We conclude that the allegations against ToM for positing UA are seriously misdirected. We further bring out an important stipulation of any account of observability of mental states: mental states are not observable in the same way as the sensory properties of physical objects.

We investigated whether (a) people positively reevaluate the characters of recently dead others and (b) supernatural primes concerning an ambient dead agent serve to curb selfish intentions. In Study 1, participants made trait attributions to three strangers depicted in photographs; one week later, they returned to do the same but were informed that one of the strangers had died over the weekend. Participants rated the decedent target more favorably after learning of his death whereas ratings for the control targets remained (...) unchanged between sessions. This effect was especially pronounced for traits dealing with the decedent’s prosocial tendencies (e.g., ethical, kind). In Study 2, a content analysis of obituaries revealed a similar emphasis on decedents’ prosocial attributes over other personality dimensions (e.g., achievement-relatedness, social skills). Finally, in Study 3, participants who were told of an alleged ghost in the laboratory were less likely to cheat on a competitive task than those who did not receive this supernatural prime. The findings are interpreted as evidence suggestive of adaptive design. (shrink)

This paper argues that, while there is a difference between personal and sub-personal explanation, claims of autonomy should be treated with scepticism. It distinguishes between horizontal and vertical explanatory relations that might hold between facts at the personal and facts at the sub-personal level. Noting that many philosophers are prepared to accept vertical explanatory relations between the two levels, I argue for the stronger claim that, in the case of at least three central personal level phenomena, the demands of explanatory (...) adequacy require postulating horizontal explanatory relations.

While inanimate objects can neither experience nor express emotions, in principle they can be expressive of emotions. In particular, music is a paradigmatic example of something expressive of emotions that surely cannot feel anything at all. The Contour theory accounts for music expressiveness in terms of those resemblances that hold between its external and perceivable properties and the typical contour of human emotional behavior. Provided that some critical aspects are emended – notably, the stress on the perception of similarity instead (...) of the more plausible hypothesis that the listener perceives manifestations that are similar – we are inclined to endorse contour theory. In particular, we share its basic idea that expressive properties are perceived. Although other kinds of processes – high-level conceptual inferences, imagination – sometimes characterize our encounters with music, still perception constitutes the standard process underlying the detection of expressiveness. Moreover, we propose to extend contour theory to visual arts. Taking into consideration, as a case study, depicted landscapes, we observe that they frequently cannot but express emotions such as joy, sadness, liveliness or melancholy. The fact that pictures, unlike music, lack any temporal dimension is a prima facie reason for doubting the extendibility of contour theory’s conceptual arsenal to them. Nevertheless, while being obviously unable to behave somehow, we claim that depicted landscapes can perfectly convey dynamic information. If this is the case, the extension of the notion of contour to visuals art via the stress on the notion of dynamism would represent a second interesting revision of contour theory. (shrink)

In these notes, unadorned page numbers under 350 refer to Dennett (1987) - The Intentional Stance, hereafter referred to as Stance - and ones over 495 refer to Dennett (1988) - mostly to material by him but occasionally to remarks of his critics. Since the notes will focus on disagreements, I should say now that I am in Dennett’s camp and am deeply in debt to his work in the philosophy of mind, which I think is wider, deeper, more various (...) and more fruitful than mine or anyone else’s. Still, I have some ideas and emphases that I think he could profit from. In the final chapter of Stance Dennett compares his work with that of several others, including me. He sees me as having a position like his, the main difference being that I think (as he doesn’t) that our attributions of mental content can always be highly determinate (pp. 347f). In fact, there are differences between us but this isn’t one of them. I want to get this straight, so as to clear the decks for the positive points I am going to make. There is some indeterminacy and there could be lots of it; Dennett’s case for that is unanswerable. As for how much there actually is: I don’t know and don’t even suspect; there is simply no declared issue between Dennett and myself on that. Nor do we disagree on a related matter. If there is no evidence that settles whether the animal believes that P or believes that Q, should we say that nevertheless one of these is right, and it’s just that we can’t know which it is? Dennett says No. I perfectly agree. (shrink)

In this article, I address the issue of evil and roboethics in the context of management studies and suggest that management scholars should locate evil in the realm of the human rather than of the artificial. After discussing the possibility of addressing the reality of evil machines in ontological terms, I explore users’ reaction to robots in a social context. I conclude that the issue of evil machines in management is more precisely a case of technology anthropomorphization.

No philosopher has worked harder than Dan Dennett to set the possibility of machine mentality on firm philosophical footing. Dennett’s defense of this possibility has both a positive and a negative thrust. On the positive side, he has developed an account of mental activity that is tailor-made for the attribution of intentional states to purely mechanical contrivances, while on the negative side, he pillories as mystery mongering and skyhook grasping any attempts to erect barriers to the conception of machine mentality (...) by excavating gulfs to keep us “bona fide” thinkers apart from the rest of creation. While I think he’s “won” the rhetorical tilts with his philosophical adversaries, I worry that Dennett’s negative side sometimes gets the better of him, and that this obscures advances that can be made on the positive side of his program. In this paper, I show that Dennett is much too dismissive of original intentionality in particular, and that this notion can be put to good theoretical use after all. Though deployed to distinguish different grades of mentality, it can (and should) be incorporated into a philosophical account of the mind that is recognizably Dennettian in spirit. (shrink)

The crucial point of the mind-body-problem appears to be that mental phenome- na (events, properties, states) seem to have features which at first sight make it impossible to integrate these phenomena into a naturalistic world view, i.e. to identify them with, or to reduce them to, physical phenomena.1 In the contemp- orary discussion, there are mainly two critical features which are important in this context. The first of these is the feature of intentional states, e.g. beliefs and desires, to have (...) a representational or semantic content. The problem of the naturalization of these states I will call the problem of intentionality. The second critical feature is the property of other mental states, e.g. perceptions and sensations, to have a qualitative aspect, i.e. that it is somehow, or feels in a characteristic way, to be in one of those states. The problem of the naturalization of these states is generally called the qualia-problem. (shrink)

Cimpian & Salomon's characterization of a domain-general inherence heuristic, available to young children, underplays the importance of our early interest in and recognition of agency, intentionality, and mental life. A consideration of the centrality of desires, goals, and agency in our earliest reasoning suggests an alternative, perhaps complementary, account of our tendency to be satisfied with the status quo.

We consider the various criticisms and requests for clarification made by the commentators of our framework for understanding intentional relations. Our response is organized according to the main themes in the target article: general theory, phylogeny, development, and autism. We also add some discussion of further issues, such as simulation and moral theory, that were not addressed in the target article.

Several recent criticisms of the somatic marker hypothesis (SMH) identify multiple ambiguities in the way it has been formulated by its chief proponents. Here we provide evidence that this hypothesis has also been interpreted in various different ways by the scientific community. Our diagnosis of this problem is that SMH lacks an adequate computational-level account of practical decision making. Such an account is necessary for drawing meaningful links between neurological- and psychological-level data. The paper concludes by providing a simple, five-step (...) model of practical decision making. Recasting SMH in terms of this model generates more precise and empirically tractable computational-level hypotheses about the various ways that somatic markers might influence practical decisions.

Barresi & Moore contrast two theories of autism: (1) in autism there is a general inability to integrate first and third person information (of any kind), and (2) in autism there is a specific inability to represent an agent's perceptual or volitional mental state being about another agents mental state. Two lines of experimental evidence suggest that the first of these is too broad, favoring instead the more specific “theory of mind” account.

According to what I call the ‘Vagueness Thesis’ about belief, ‘believes’ is a vague predicate. On this view, our concept of belief admits of borderline cases: one can ‘half-believe’ something or be ‘in-between believing’ it. In this article, I argue that VT is false and present an alternative picture of belief. I begin by considering a case—held up as a central example of vague belief—in which someone sincerely claims something to be true and yet behaves in a variety of other (...) ways as if she believes that it is not. I argue that, even from the third-person perspective prioritised by proponents of VT, the case does not motivate VT. I present an alternative understanding of the case according to which the person in question believes as they say they do yet also has a belief-discordant implicit attitude otherwise. Moreover, I argue that, independently of the interpretation of any particular case, VT fails to accommodate the first-person perspective on belief. Belief is not only an item of one’s psychology that helps explain one’s behaviour; it is what one takes to be true. This fact about belief manifests itself in the nature of deliberation concerning whether to believe something and that of introspection regarding whether one believes something. Attending to these phenomena reveals that VT is not merely unmotivated, but untenable. (shrink)
