In the last few decades, there has been a genuine ‘adaptive turn’ in psychiatry, resulting in evolutionary accounts for an increasing number of psychopathologies. In this paper, I explore the advantages and problems with the two main evolutionary approaches to depression, namely the mismatch and persistence accounts . I will argue that while both evolutionary theories of depression might provide some helpful perspectives, the accounts also harbor significant flaws that might question their authority and usefulness as explanations.

The subjective delight associated with the creative arts poses a well-known challenge to an integrated causal analysis of human psychology. Here we examine the distal causes of art in terms of an irreducibly risky search in a vast phase space of cognition and behavior. To explore means to engage in an activity that may result in a zero or negative payoff. Moreover, you may be unable to assess the risks with any certainty; the costs might spiral out of control. At (...) the same time, the known alternatives may simply not be viable; natural selection has no problems acting on the failure to locate new habitable subspaces. This represents the hard problem of evolution: there is no recurring procedure that will reliably deliver the benefits of a successful exploration. We propose to locate the emergence of play and art in the tension between the irreducible risks of exploration and its potential benefits and examine the complex suite of adaptations that has emerged to solve, however, imperfectly, the hard problem of evolution. This includes adaptations for lowering the cost of exploration and strategies for open-ended yet loosely targeted searches. We argue that the ability to become aware of possible actions, to evaluate their respective merits, and to explore and develop new strategies of perception, thinking, and action have had a major impact on human survival and reproduction and have been subject to persistent natural selection. The arts, we suggest, represent a distinct cognitive mode of pushing the boundaries of what is familiar and known into new areas of perceptual, emotional, and agentive exploration and discovery, characterized by a proximal motivation of intrinsic enjoyment.

In this article, I defend Neo-Gricean accounts of language and communication from an objection about linguistic development. According to this objection, children are incapable of understanding the minds of others in the way that Neo-Gricean accounts require until long after they learn the meanings of words, are able to produce meaningful utterances, and understand the meaningful utterances of others. In answering this challenge, I outline exactly what sorts of psychological states are required by Neo-Gricean accounts and conclude that there is (...) sufficient evidence that these types of psychological states are present in and capable of being understood by the children in question.

Since social skills are highly significant to the evolutionary success of humans, we should expect these skills to be efficient and reliable. For many Evolutionary Psychologists efficiency entails encapsulation: the only way to get an efficient system is via information encapsulation. But encapsulation reduces reliability in opaque epistemic domains. And the social domain is darkly opaque: people lie and cheat, and deliberately hide their intentions and deceptions. Modest modularity [Currie and Sterelny (2000) Philos Q 50:145–160] attempts to combine efficiency and (...) reliability. Reliability is obtained by placing social skills in un-encapsulated central cognition; efficiency by having the social system sensitive to encapsulated socially tagged cues. In this paper, I argue that this approach fails. I focus on eye-gaze as a plausible example of a socially significant encapsulated cue. I demonstrate contra modest modularity that eye-gaze is subject to influence from central cognition. (shrink)

Abstract.The biological and cognitive approach to religion has matured somewhat and reveals interesting results. Nevertheless, some questions arise about its foundation and development. The essay offers a review of current research in the cognitive field, focusing on its conclusions, the internal discussions, and the problems that need more study or correction. Emphasis is placed on a more intricate account of the factors involved in religious experience, discussing the proper use of the discoveries of biocognitive research and the limits that should (...) be placed on said conclusions.

Episodic memory has been analyzed in a number of different ways in both philosophy and psychology, and most controversy has centered on its self-referential,autonoeticcharacter. Here, we offer a comprehensive characterization of episodic memory in representational terms and propose a novel functional account on this basis. We argue that episodic memory should be understood as a distinctive epistemic attitude taken toward an event simulation. In this view, episodic memory has a metarepresentational format and should not be equated with beliefs about the (...) past. Instead, empirical findings suggest that the contents of human episodic memory are often constructed in the service of the explicit justification of such beliefs. Existing accounts of episodic memory function that have focused on explaining its constructive character through its role in future-oriented mental time travel do justice neither to its capacity to ground veridical beliefs about the past nor to its representational format. We provide an account of the metarepresentational structure of episodic memory in terms of its role in communicative interaction. The generative nature of recollection allows us to represent and communicate the reasons why we hold certain beliefs about the past. In this process, autonoesis corresponds to the capacity to determine when and how to assert epistemic authority in making claims about the past. A domain where such claims are indispensable are human social engagements. Such engagements commonly require the justification of entitlements and obligations, which is often possible only by explicit reference to specific past events. (shrink)

The phenomenon of religious belief has been much discussed in philosophy of religion. However, a priori argumentation alone cannot establish what religious belief is like as a psychological attitude. Recent advances in the cognitive science of religion have paved the way for a new, naturalized philosophy of religion. Taking into account the relevant results and hypotheses presented within these disciplines, it is possible to develop a more empirically informed philosophy of religious belief. Instead of asking whether believing is rational, it (...) is here asked how religious belief is cognitively possible. Combining Boyer's evolutionary account of religion with Sperber's and Cosmides and Tooby's theory of metarepresentation, we get the sort of conceptual toolkit needed to specify those cognitive mechanisms and operations that make religious belief possible. Religious belief is shown to require a unique combination of these mechanisms and operations. (shrink)

Research on folk epistemology usually takes place within one of two different paradigms. The first is centered on epistemic theories or, in other words, the way people think about knowledge. The second is centered on epistemic intuitions, that is, the way people intuitively distinguish knowledge from belief. In this paper, we argue that insufficient attention has been paid to the connection between the two paradigms, as well as to the mechanisms that underlie the use of both epistemic intuitions and theories. (...) We contend that research on folk epistemology must examine the use of both intuitions and theories in the pragmatic context of the game of giving and asking for reasons and, more generally, understand how these practices take place within the broader context of normative social cognition.

Currently, there is widespread skepticism that higher cognitive processes, given their apparent flexibility and globality, could be carried out by specialized computational devices, or modules. This skepticism is largely due to Fodor’s influential definition of modularity. From the rather flexible catalogue of possible modular features that Fodor originally proposed has emerged a widely held notion of modules as rigid, informationally encapsulated devices that accept highly local inputs and whose opera- tions are insensitive to context. It is a mistake, however, to (...) equate such features with computational devices in general and therefore to assume, as Fodor does, that higher cognitive processes must be non-computational. Of the many possible non-Fodorean architectures, one is explored here that offers possible solutions to computational problems faced by conventional modular systems: an ‘enzymatic’ architecture. Enzymes are computational devices that use lock-and-key template matching to iden- tify relevant information (substrates), which is then operated upon and returned to a common pool for possible processing by other devices. Highly specialized enzymes can operate together in a common pool of information that is not pre-sorted by information type. Moreover, enzymes can use molecular ‘tags’ to regulate the operations of other devices and to change how particular substrates are construed and operated upon, allowing for highly interactive, context-specific processing. This model shows how specialized, modular processing can occur in an open system, and suggests that skepti- cism about modularity may largely be due to failure to consider alternatives to the standard model.

The domain of “folk-economics” consists in explicit beliefs about the economy held by laypeople, untrained in economics, about such topics as, for example, the causes of the wealth of nations, the benefits or drawbacks of markets and international trade, the effects of regulation, the origins of inequality, the connection between work and wages, the economic consequences of immigration, or the possible causes of unemployment. These beliefs are crucial in forming people's political beliefs and in shaping their reception of different policies. (...) Yet, they often conflict with elementary principles of economic theory and are often described as the consequences of ignorance, irrationality, or specific biases. As we will argue, these past perspectives fail to predict the particular contents of popular folk-economic beliefs and, as a result, there is no systematic study of the cognitive factors involved in their emergence and cultural success. Here we propose that the cultural success of particular beliefs about the economy is predictable if we consider the influence of specialized, largely automatic inference systems that evolved as adaptations to ancestral human small-scale sociality. These systems, for which there is independent evidence, include free-rider detection, fairness-based partner choice, ownership intuitions, coalitional psychology, and more. Information about modern mass-market conditions activates these specific inference systems, resulting in particular intuitions, for example, that impersonal transactions are dangerous or that international trade is a zero-sum game. These intuitions in turn make specific policy proposals more likely than others to become intuitively compelling, and, as a consequence, exert a crucial influence on political choices. (shrink)

This article addresses issues in the philosophy of fiction from the perspective of a relevance theoretic approach to communication: first, how should we understand the notion of ‘voice’ as it is used in the analysis of free indirect style narratives; and, second, in what sense can the person responsible for free indirect representations of fictional characters' thoughts be regarded as a communicator? The background to these questions is the debate about the roles of pretence and attribution in free indirect style. (...) I argue that the role of expressives in sustaining the illusion that fictional characters speak their inner thoughts suggests that ‘voice’ should be understood in two distinct ways. On the one hand, there are cases in which the use of expressive devices leads to the formation of thoughts which are understood to resemble other (attributed) thoughts. On the other hand, there are other cases in which expressives are used as a means of simulating a fictional character's behaviour or style. At the same time, I argue that in order to accommodate free indirect thought representation in a relevance theoretic model of communication, the responsibility for ensuring that the effort of processing the text will be rewarded by optimal relevance must be decoupled from the point of view that is being represented. While the (constructed) author is responsible for orchestrating our interpretation of free indirect thought representations so that the effort of processing will result in optimal relevance, the reader does not necessarily assume this function is being performed by someone who intends to communicate their own thoughts: the relevance of the act of narration may instead lie in the sense of mutuality achieved between reader and character.

My hypothesis is that the cognitive challenge posed by death might have had a co-evolutionary role in the development of linguistic faculties. First, I claim that mirror neurons, which enable us to understand others’ actions and emotions, not only activate when we directly observe someone, but can also be triggered by language: words make us feel bodily sensations. Second, I argue that the death of another individual cannot be understood by virtue of the mirror neuron mechanism, since the dead provide (...) no neural pattern for mirroring: this cognitive task requires symbolic thought, which in turn involves emotions. Third, I describe the symbolic leap of the human species as a cognitive detachment from the here and now, allowing displaced reference: through symbols the human mind can refer to what is absent, possible, or even impossible (like the presence of a dead person). Such a detachment has had a huge adaptive impact: adopting a coevolutionary standpoint can help explain why language is as effective as environmental inputs in order to stimulate our bodily experience. In the end I suggest a further coevolutionary reversal : if language is necessary to understand the death of the other, it might also be true that the peculiar cognitive problem posed by the death of the other (the corpse is present, but the other is absent) has contributed to the crucial transition from an indexical sign system to the symbolic level, i.e., the cognitive detachment . Death and language, as Heidegger claimed, have an essential relation for humans, both from an evolutionary and a phenomenological perspective: they have shaped the symbolic consciousness that make us conceive of them.

The task of explaining language evolution is often presented by leading theorists in explicitly Gricean terms. After a critical evaluation, I present an alternative, non-Gricean conceptualization of the task. I argue that, while it may be true that nonhuman animals, in contrast to language users, lack the ‘motive to share information’ understood à la Grice, nonhuman animals nevertheless do express states of mind through complex nonlinguistic behavior. On a proper, non-Gricean construal of expressive communication, this means that they show to (...) their designated audience (without intentionally telling)—and their designated audience recognizes (without rationally inferring)—both how things are in the world and how things are with them. Recognizing that our nonhuman predecessors were already proficient—though non-Gricean—sharers of such information would free us to focus on the more tractable problem of explaining how linguistic expressive vehicles came to replace, augment, and transform the nonlinguistic expressive means to which nonhuman animals are consigned.

Sciences able to identify appropriate analytical units for their domain, their natural kinds, have tended to be more progressive. In the biological sciences, evolutionary natural kinds are adaptations that can be identified by their common history of selection for some function. Human brains are the product of an evolutionary history of selection for component systems which produced behaviours that gave adaptive advantage to their hosts. These structures, behaviour production systems, are the natural kinds that psychology seeks. We argue these can (...) be identified deductively by classing behaviour first according to its level of behavioural control. Early animals in our lineage used only reactive production, Vertebrates evolved motivation, and later Primates developed executive control. Behaviour can also be classified by the type of evolutionary benefit it bestows: it can deliver either immediate benefits (food, gametes), improvements in the individual’s position with respect to the world (resource access, social status), or improvements in the ability to secure future benefits (knowledge, skill). Combining history and function implies the existence of seven types of behaviour production systems in human brains responsible for reflexive, instinctual, exploratory, driven, emotional, playful and planned behaviour. Discovering scientifically valid categories of behaviour can provide a fundamental taxonomy and common language for understanding, predicting and changing behaviour, and a way of discovering the organs in the brain––its natural kinds––that are responsible for behaviour.

Although recent trends in politics and media make it appear that conspiracy theories are on the rise, in fact they have always been present, probably because they are sustained by natural dispositions of the human brain. This is also the case with medical conspiracy theories. This article reviews some of the most notorious health-related conspiracy theories. It then approaches the reasons why people believe these theories, using concepts from cognitive science. On the basis of that knowledge, the article makes normative (...) proposals for public health officials and health workers as a whole, to deal with conspiracy theories, in order to preserve some of the fundamental principles of medical ethics.
