A persistent methodological problem in primate social cognition research has been how to determine experimentally whether primates represent the internal goals of other agents or just the external goals of their actions. This is an instance of Daniel Povinelli’s more general challenge that no experimental protocol currently used in the field is capable of distinguishing genuine mindreading animals from their complementary behavior-reading counterparts. We argue that current methods used to test for internal-goal attribution in primates do not solve Povinelli’s problem. (...) To overcome the problem, a new type of experimental approach is needed, one which is supported by an alternative theoretical account of animal mindreading, called the appearance-reality mindreading (ARM) theory. We provide an outline of the ARM theory and show how it can be used to design a novel way to test for internal-goal attribution in chimpanzees. Unlike protocols currently in use, the experimental design presented here has the power, in principle and in practice, to distinguish genuine mindreading chimpanzees from those who predict others’ behavior solely on the basis of behavioral/environmental cues. Our solution to Povinelli’s problem has important consequences for a similar debate in developmental psychology over when preverbal infants should be credited with the ability to attribute internal goals. If what we argue for here in the case of nonhuman primates is sound, then the clearest tests for internal-goal attribution in infants will be those that test for attributions of discrepant or ‘false’ perceptions.

Sterelny’s Thought in a Hostile World ([ 2003 ]) presents a complex, systematically structured theory of the evolution of cognition centered on a concept of decoupled representation. Taking Godfrey-Smith’s ([ 1996 ]) analysis of the evolution of behavioral flexibility as a framework, the theory describes increasingly complex grades of representation beginning with simple detection and culminating with decoupled representation, said to be belief-like, and it characterizes selection forces that drive evolutionary transformations in these forms of representation. Sterelny’s ultimate explanatory target (...) is the evolution of human agency. This paper develops a detailed analysis of the main cognitive aspects. It is argued that some of the major claims are not correct: decoupled representation as defined doesn’t capture belief-like representation, and, properly understood, decoupled representation turns out to be ubiquitous among multicellular animals. However, some of the key ideas are right, or along the right lines, and suggestions are made for modifying and expanding the conceptual framework. (shrink)

Here I briefly discuss some comparative data on social play behaviour in hope of broadening the array of species in which researchers attempt to study animal morality. I am specifically concerned with the notion of ‘behaving fairly'. In the term ‘behaving fairly’ I use as a working guide the notion that animals often have social expectations when they engage in various sorts of social encounters the violation of which constitutes being treated unfairly because of a lapse in social etiquette. I (...) will cash this out below in my discussion of social play behaviour. (shrink)

Recent advances in evolutionary biology and ethology suggest that humans are not the only species capable of empathy and possibly morality. These findings are of no little consequence for theology, given that a nonhuman animal as a free moral agent would beg the question if human beings are indeed uniquely created in God's image. I argue that apes and some other mammals have moral agency and that a traditional interpretation of the imago Dei is incorrectly equating specialness with exclusivity. By (...) framing the problem in terms of metaphor, following the work of Paul Ricoeur and Sallie McFague, I propose that the concept of the imago Dei could be extended to accommodate moral species other than our own.

Studies of animal culture have not normally included a consideration of cetaceans. However, with several long-term field studies now maturing, this situation should change. Animal culture is generally studied by either investigating transmission mechanisms experimentally, or observing patterns of behavioural variation in wild populations that cannot be explained by either genetic or environmental factors. Taking this second, ethnographic, approach, there is good evidence for cultural transmission in several cetacean species. However, only the bottlenose dolphin (Tursiops) has been shown experimentally to (...) possess sophisticated social learning abilities, including vocal and motor imitation; other species have not been studied. There is observational evidence for imitation and teaching in killer whales. For cetaceans and other large, wide-ranging animals, excessive reliance on experimental data for evidence of culture is not productive; we favour the ethnographic approach. The complex and stable vocal and behavioural cultures of sympatric groups of killer whales (Orcinus orca) appear to have no parallel outside humans, and represent an independent evolution of cultural faculties. The wide movements of cetaceans, the greater variability of the marine environment over large temporal scales relative to that on land, and the stable matrilineal social groups of some species are potentially important factors in the evolution of cetacean culture. There have been suggestions of gene-culture coevolution in cetaceans, and culture may be implicated in some unusual behavioural and life-history traits of whales and dolphins. We hope to stimulate discussion and research on culture in these animals. (shrink)

Moral behaviour, based on social norms, is commonly regarded as a hallmark of humans. Hitherto, humans are perceived to be the only species possessing social norms and to engage in moral behaviour. There is anecdotal evidence suggesting their presence in chimpanzees, but systematic studies are lacking. Here, we examine the evolution of human social norms and their underlying psychological mechanisms. For this, we distinguish between conventions, cultural social norms and universal social norms. We aim at exploring whether chimpanzees possess evolutionary (...) precursors of universal social norms seen in humans. Chimpanzees exhibit important preconditions for their presence and enforcement: tolerant societies, well-developed social-cognitive skills and empathetic competence. Here, we develop a theoretical framework for recognizing different functional levels of social norms and distinguish them from mere statistical behavioural regularities. Quasi social norms are found where animals behave functionally moral without having moral emotions. In proto social norms, moral emotions might be present but cannot be collectivized due to the absence of a uniquely human psychological trait, i.e. shared intentionality. Human social norms, whether they are universal or cultural, involve moral emotions and are collectivized. We will discuss behaviours in chimpanzees that represent potential evolutionary precursors of human universal social norms, with special focus on social interactions involving infants. We argue that chimpanzee infants occupy a special status within their communities and propose that tolerance towards them might represent a proto social norm. Finally, we discuss possible ways to test this theoretical framework. (shrink)

According to the dual inheritance theory, cultural learning in our species is a biased and highly efficient process of transmitting cultural traits. Here we define a model of cultural learning where social learning is integrated as a complementary element that facilitates the discovery of a specific behavior by an apprentice, and not as a mechanism that works in opposition to individual learning. In that context, we propose that the emergence of the ability to approve or disapprove of offspring behavior, orienting (...) their learning, transformed primate social learning into a cultural transmission system, like that which characterizes our species. Assessor teaching facilitates the replication and/or reconstruction of behaviors that are difficult to imitate and helps to determine which behaviors should be imitated. We also explore the form in which assessor teaching has conditioned the evolution of our abilities to develop cultures in the hominin line, converting us into individuals equipped with what we call a suadens psychology. Our main point is to defend the hypothesis that suadens psychology determines the stability and dynamics that affect the trajectories of many cultural characters. We compare our proposal with other theories about cultural evolution, specifically with dual inheritance theory and cultural attraction theory. (shrink)

I argue for a soft compatibilist theory of free will, i.e., such that free will is compatible with both determinism and indeterminism, directly opposite hard incompatibilism, which holds free will incompatible both with determinism and indeterminism. My intuitions in this book are primarily based on an analysis of meditation, but my arguments are highly syncretic, deriving from many fields, including behaviorism, psychology, conditioning and deconditioning theory, philosophy of language, philosophy of mind, simulation theory, etc. I offer a causal/functional analysis of (...) meta-mental control, or 'metacausality', cashed out in counterfactual terms, to solve what I call the easy problem of free will.

Human language, hominin tool production modes, and multimodal communications systems of primates and other animals are currently well-studied for how they display compositionality or combinatoriality. In all cases, the former is defined as a kind of hierarchical nesting and the latter as a lack thereof. In this article, I extend research on combinatoriality and compositionality further to investigations of everyday primate skills. Daily locomotion modes as well as behaviors associated with subsistence practices, hygiene, or body modification rely on the hierarchical (...) nesting of different behavioral and cognitive actions into complex skills. I introduce a scheme which uses hierarchical organization to differentiate combinatorial from compositional skills. Combinatorial skills are defined either as aggregational or linearly hierarchical depending on whether the skill occurs momentarily in space or unfolds sequentially over time. Compositional skills are defined either as nested or interactionally hierarchical depending on whether the skill results in new constructs or in new interactions between existing constructs. The methodology I propose combines epistemological hierarchy theory with data from primatological field research and experimental and comparative psychological research and provides a means to integrate current constructionist and extended views on cognition and action with older research on behavioral logics in psychology and operational chain thinking in anthropology. The approach furthermore synchronizes with ongoing research on teleonomy, intentionality, and creativity. -/- . (shrink)

The evolution of human language, and the kind of thought the communication of which requires it, raises considerable explanatory challenges. These systems of representation constitute a radical discontinuity in the natural world. Even species closely related to our own appear incapable of either thought or talk with the recursive structure, generalized systematicity, and task-domain neutrality that characterize human talk and the thought it expresses. W. Tecumseh Fitch’s proposal (2004, in press) that human language is descended from a sexually selected, prosodic (...) proto-language that approximated its syntactic complexity, and later acquired semantics thanks to kin selection for its use as a means of pedagogical transmission, has the promise of meeting these explanatory challenges. However, Fitch’s theory raises two problems of its own: (1) according to Boyd and Richerson (1996, Proc. Br. Acad. 88: 77–93), circumstances in which pedagogy is adaptive are inevitably rare in nature, and (2) it is unlikely that our non-discursive precursors had generally systematic, task-domain neutral thoughts to communicate to their offspring. I propose solutions to these problems. Pedagogy would be favored in a population where complex rituals dominated diverse aspects of life. Prosodic proto-language could emerge as the medium of pedagogic transmission. As this medium was used to teach a greater variety of tasks, it would become increasingly general and domain neutral. The presence and importance of such a system of communication in hominid populations could then drive, via Baldwinian mechanisms, the evolution of a kind of ‘thinking for speaking’ (Slobin 1991, Pragmatics 1: 7–25) characterized by recursive structure, generalized systematicity, and task-domain neutrality.

I argue for two claims. First I argue against the consensus view that accurate behavioral prediction based on accurate representation of cognitive states, i.e. mind reading , is the sustaining function of propositional attitude ascription. This practice cannot have been selected in evolution and cannot persist, in virtue of its predictive utility, because there are principled reasons why it is inadequate as a tool for behavioral prediction. Second I give reasons that favor an alternative account of the sustaining function of (...) propositional attitude ascription. I argue that it serves a mind-shaping function. Roughly, propositional attitude ascription enables human beings to set up regulative ideals that function to mold behavior so as to make it easier to coordinate with. (shrink)

Toolmaking requires motor skills that in turn require handedness, so that there is no competition between the two sides of the brain. Thus, handedness is not necessarily linked to vocalization but to the origin of causal beliefs required for making complex tools. Language may have evolved from these processes.

The human primate is a deeply cultural species, our cognition being shaped by culture, and cultural transmission amounting to an “epidemic of mental representations” (Sperber, 1996). The architecture of this aspect of human cognition has been shaped by our evolutionary past in ways that we can now begin to discern through comparative studies of other primates. Processes of social learning (learning from others) are important for cognitive science to understand because they are cognitively complex and take many interrelated forms; they (...) shape traditions, cultures and nonsocial aspects of cognition; and in turn they may be shaped by their cultural context. The study of primate social learning and culture has in recent years enjoyed a renaissance, providing a wealth of new findings, key aspects of which are reviewed. The focus is on cognitive issues, including learning about the consequences, sequential structure and hierarchical organization of actions; relating stored knowledge to the assimilation of new social knowledge; feedback guiding the construction of imitations; conceptual grasp of imitation; and the reciprocal relationship between social learning and culture.

The consensus among cultural evolutionists seems to be that human cultural evolution is cumulative, which is commonly understood in the specific sense that cultural traits, especially technological traits, increase in complexity over generations. Here we argue that there is insufficient credible evidence in favor of or against this technological complexity thesis. For one thing, the few datasets that are available hardly constitute a representative sample. For another, they substantiate very specific, and usually different versions of the complexity thesis or, even (...) worse, do not point to complexity increases. We highlight the problems our findings raise for current work in cultural-evolutionary theory, and present various suggestions for future research. (shrink)

The zone of latent solutions hypothesis provides an alternative approach to explaining cultural patterns in primates and many other animals. According to the ZLS hypothesis, non-human great ape cultures consist largely or solely of latent solutions. The current competing hypothesis for ape culture argues instead that at least some of their behavioural or artefact forms are copied through specific social learning mechanisms and that their forms may depend on copying. In contrast, the ape ZLS hypothesis does not require these forms (...) to be copied. Instead, it suggests that several social learning mechanisms help determine the frequency of these behaviours and artefacts within connected individuals. The ZLS hypothesis thus suggests that increases and stabilisations of a particular behaviour’s or artefact’s frequency can derive from socially-mediated form reinnovations. Therefore, and while genes and ecology play important roles as well, according to the ape ZLS hypothesis, apes typically acquire the forms of their behaviours and artefacts individually, but are usually socially induced to do so. The ZLS approach is often criticized—perhaps also because it challenges the current null hypothesis, which instead assumes a requirement of form-copying social learning mechanisms to explain many ape behavioural forms. However, as the ZLS hypothesis is a new approach, with less accumulated literature compared to the current null hypothesis, some confusion is to be expected. Here, we clarify the ZLS approach—also in relation to other competing hypotheses—and address misconceptions and objections. We believe that these clarifications will provide researchers with a coherent theoretical approach and an experimental methodology to examine the necessity of form-copying variants of social learning in apes, humans and other species.

This article identifies already existing theoretical and methodological commonalities between evolutionary biology and phenomenology, concentrating specifically on their common pursuit of origins. It identifies in passing theoretical support from evolutionary biology for present-day concerns in philosophy, singling out Sartre’s conception of fraternity as an example. It anchors its analysis of the common pursuit of origins in Husserl’s consistent recognition of the grounding significance of Nature and in his consistent recognition of animate forms of life other than human. It enumerates and (...) exemplifies five basic errors of continental philosophers with respect to Nature, errors testifying to a philosophical fundamentalism that distorts the intricate interconnections and relationships of Nature in favor of a preferred knowledge rooted in ontological reductionism. It shows that to discover and appreciate the common ground, one must indeed study “the things themselves.”. (shrink)

In this paper I evaluate embodied social cognition, embodied cognition’s account of how we understand others. I identify and evaluate three claims that motivate embodied social cognition. These claims are not specific to social cognition; they are general hypotheses about cognition. As such, they may be used in more general arguments for embodied cognition. I argue that we have good reasons to reject these claims. Thus, the case for embodied social cognition fails. Moreover, to the extent that general arguments for (...) embodied cognition rest on these premises, they are correspondingly uncompelling. (shrink)

Communication is a fundamentally interactive phenomenon. Evolutionary biology recognises this fact in its definition of communication, in which signals are those actions that cause reactions, and where both action and reaction are designed for that reason. Where only one or the other is designed then the behaviours are classed as either cues or coercion. Since mutually dependent behaviours are unlikely to emerge simultaneously, the symmetry inherent in these definitions gives rise to a prediction that communication will only emerge if cues (...) or coercive behaviours do so first. They will then be co-opted for communication. A range of case studies, from animal signalling, evolutionary robotics, comparative psychology, and evolutionary linguistics are used to test this prediction. The first three are found to be supportive. However in the Embodied Communication Game, a recent experimental approach to the emergence of communication between adult humans, communication emerges even when cues or coerced behaviours are not possible. This suggests that humans are exceptional in this regard. It is argued that the reason for this is the degree to which we are able and compelled to read and interpret the behaviour of others in intentional terms. (shrink)

Research on mirror self-recognition where animals are observed for mirror-guided self-directed behaviour has predominated the empirical approach to self-awareness in nonhuman primates. The ability to direct behaviour to previously unseen parts of the body such as the inside of the mouth, or grooming the eye by aid of mirrors has been interpreted as recognition of self and evidence of a self-concept. Three decades of research has revealed that contrary to monkeys, most great apes have convincingly displayed the capacity to recognize (...) self by mirrors. The putative discontinuity in phylogeny of the ability suggests the existence of a so-called cognitive gap between great apes and the rest of the animal kingdom. However, methodological and theoretical inconsistencies regarding the empirical approach prevail. For instance, the observation of self-directed behaviour might not be as straightforward as it seems. In addition, the interpretation of mirror self-recognition as an index of self-awareness is challenged by alternative explanations, raising doubt about some assumptions behind mirror self-recognition. To evaluate the significance of the test in discussions of the concept of self this paper presents and analyses some major arguments raised on the mirror task. (shrink)

The human adventure in education is one of imperfect expression, punctuated by moments of insight. Education cultivates these epiphanies and nurtures their possible continuation. But even without major or minor insights, education cultivates the appreciation of the good, the beautiful, and the true. An experimentalist's sensibility lies amid the humanist's grasp of the myriad ways of trying to understand our existence. To bridge discourse is to appreciate the languages of other cultures, which reveal the nuances of life and experience.

Mind is seen as a collection of abilities to take decisions in biologically relevant situations. Mind shaping means to form habits and decision rules of how to proceed in a given situation. Problem-specific decision rules constitute a modular mind; adaptive mind-shaping is likely to be module-specific. We present examples from different behaviour ‘faculties’ throughout the animal kingdom, grouped according to important mind-shaping factors to illustrate three basically different mind-shaping processes: external stimuli guide the differentiation of a nervous structure that controls (...) a given behaviour; information comes in to direct a fixed behaviour pattern to its biological goal, or to complete an inherited behaviour program; specific stimuli activate or inactivate a pre-programmed behaviour. Mind-shaping phenomena found in the animal kingdom are suggested as ‘null-hypotheses’ when looking at how human minds might be shaped. (shrink)

The conclusions drawn from mirror self-recognition studies, in which nonhuman animals are tested for whether they detect a mark on their bodies which can be observed only in the mirror, are based on several presuppositions. These include that performance on the test is an indication of species wide rather than individual abilities, and that all the animals which pass the test are demonstrating the presence of the same psychological ability. However, further details about the results of the test indicate that (...) these presuppositions are false. Animals take the test as individuals, not as stand-ins for species, and members of different species rely on different cognitive mechanisms to pass the test. For nonhuman animals, passing the test seems to be a consequence of enculturation and practice. (shrink)

Current Perspectives in Philosophy of Biology.

This article critically examines the ways in which primatologists account for their research. Based on a series of unstructured interviews, it argues that the location of primates at the boundary between Western conceptions of nature and culture or human and animal has materially affected how primatologists talk about their research, what they find possible to write about in their research, and where they choose to publish their research. Through the discussion of a number of related topics, it outlines the reflexive (...) nature of primatologists’ response to the cultural positioning of their research subjects. (shrink)

De modo semelhante aos rompantes etnocêntricos de uma cultura humana frente a outras, as relações entre humanos e primatas não humanos incluem um estranhamento pontuado por atração e repulsa, identificação e diferença. Ciência, arte e mitologia são a expressão viva e atualizada disso. Desde 1960, a primatologia destaca-se nesse cenário por contribuir significativamente na revisão das definições sobre o comportamento dos primatas e, consequentemente, na redefinição do humano ao apresentar a polêmica proposição de existência de "culturas" entre animais não humanos. (...) Assim, a aproximação entre humanos e primatas não humanos parece inexorável e irreversível. Isso implica, por exemplo, em cogitar se esse processo engendra, ou não, a constituição de novas alteridades a partir de um novo outro (não humano), carregado de significados. Isso incluiria, por exemplo, a reformulação de representações e de categorias de classificação, bem como o aprofundamento do debate sobre os direitos dos animais não humanos. Ao dirigir tal tipo de desafio a situações de pesquisa antropológica deve-se ter aguda consciência de que o registro etnográfico das relações entre humanos e os outros primatas será uma construção empírica, perceptual e teórica. Dado o tipo particular de relação estabelecida entre humanos e outros primatas, pautada em um universo fronteiriço de incômodas semelhanças e diferenças, constituem-se aí coletivos híbridos em que o alcance e a profundidade das interações possíveis ainda são desconhecidos. The relations between humans and non-human primates resemble the ethnocentric reaction of one human culture in relation to others, and include an estrangement marked by attraction and rejection, identification and differentiation. Art, science and myths are the vivid and updated expression of these phenomena. Since the 1960's primatology stands out in that scenario for contributing significantly to the revision of the definitions about the behavior of primates and, consequently, for the redefinition of human beings, and for making the controversial proposal of the existence of non-human animal "cultures". Then, the close connection between humans and non-human primates seems relentless and irreversible - and raises the question on whether or not these processes engender a new kind of otherness deriving from a non-human other that is full of meaning. This would include, for example, the reformulation of the representations and categories of classification, as well as deepening the debate about the rights of non-human animals. When the challenge is taken up in situations of anthropological research that address the relationships between human beings and the other primates, the ethnographic register that describes the relations between human beings and other primates will be an equally sharp empirical, perceptual and theoretical construction. Given the peculiar type of relationship established between human beings and other primates, implemented in a frontier universe of uncomfortable similarities and differences, they constituted a hybrid collective where interactions are possible but we do not know exactly how complex or how depth they are.

Abstract: Focusing on early child pretend play from the perspective of developmental psychology, this article puts forward and presents evidence for two claims. First, such play constitutes an area of remarkable individual intentionality of second-order intentionality (or 'theory of mind'): in pretence with others, young children grasp the basic intentional structure of pretending as a non-serious fictional form of action. Second, early social pretend play embodies shared or collective we-intentionality. Pretending with others is one of the ontogenetically primary instances of (...) truly cooperative actions. And it is a, perhaps the, primordial form of cooperative action with rudimentary rule-governed, institutional structure: in joint pretence games, children are aware that objects collectively get assigned fictional status, 'count as' something, and that this creates a normative space of warranted moves in the game. Developmentally, pretend play might even be a cradle for institutional phenomena more generally. (shrink)

How do human children come up to carve up and think of the world around them in its most general and abstract structure? And to which degree are these general forms of viewing the world shared by other animals, notably by non-human primates? In response to these questions of what could be called comparative metaphysics, this paper discusses new evidence from developmental and comparative research to argue for the following picture: human children and non-human primates share a basic framework of (...) natural ontology: they think about their natural surroundings in essentialist ways in terms of natural kind objects constituted by their essential properties, and in generic terms as governed by general descriptive regularities. In contrast, there is a great divide when it comes to how human children and non-human primates carve up their social environment: only human children then go on to use their essentialist and generic thinking for developing a distinctively social ontology, to conceive of their surrounding in terms of socially constituted objects governed by general prescriptive norms.

There is disagreement in the literature about the exact nature of the phenomenon of empathy. There are emotional, cognitive, and conditioning views, applying in varying degrees across species. An adequate description of the ultimate and proximate mechanism can integrate these views. Proximately, the perception of an object's state activates the subject's corresponding representations, which in turn activate somatic and autonomic responses. This mechanism supports basic behaviors that are crucial for the reproductive success of animals living in groups. The Perception-Action Model, (...) together with an understanding of how representations change with experience, can explain the major empirical effects in the literature. It can also predict a variety of empathy disorders. The interaction between the PAM and prefrontal functioning can also explain different levels of empathy across species and age groups. This view can advance our evolutionary understanding of empathy beyond inclusive fitness and reciprocal altruism and can explain different levels of empathy across individuals, species, stages of development, and situations. Key Words: altruism; cognitive empathy ; comparative; emotion; emotional contagion; empathy ; evolution; human; perception-action; perspective taking. (shrink)

The author analyses, with semiotic tools, the behaviour of a dog that she observed in Trieste, along the famous promenade called “Barcola”. The animal had been playing with its masters on the seashore and then brought back onto the avenue ready to go home. The dog repeatedly tried, with different strategies, to convince its masters to return to shore and continue their play. The tripling of the trials that is so typical of fairy tales was observed to have been enacted: (...) exactly three times, the dog reproduced the sequence of running towards the parapet, glancing over the sea with guile, running towards its masters, jumping and imploring in front of them, renouncing and walking in a backward position with a lolling head. It is argued that this behaviour demonstrates a highly structured semantic, narrative and communicative competence. This study aims at connecting Semiotics and the ecological approach to cognition that takes into account not only strictly cognitive activities but a wider spectrum of strategies through which an animal develops the adaptive behaviour requested by specific environmental conditions.

The question of whether chimpanzees, like humans, reason about unobservable mental states remains highly controversial. On one account, chimpanzees are seen as possessing a psychological system for social cognition that represents and reasons about behaviors alone. A competing account allows that the chimpanzee's social cognition system additionally construes the behaviors it represents in terms of mental states. Because the range of behaviors that each of the two systems can generate is not currently known, and because the latter system depends upon (...) the former, determining the presence of this latter system in chimpanzees is a far more difficult task than has been assumed. We call for recognition of this problem, and a shift from experimental paradigms that cannot resolve this question, to ones that might allow researchers to intelligently determine when it is necessary to postulate the presence of a system which reasons about both behavior and mental states.

Research suggests that the mind contains a set of adaptations for detecting alliances: an alliance detection system, which monitors for, encodes, and stores alliance information and then modifies the activation of stored alliance categories according to how likely they will predict behavior within a particular social interaction. Previous studies have established the activation of this system when exposed to explicit competition or cooperation between individuals. In the current studies we examine if shared political opinions produce these same effects. In particular, (...) if participants will spontaneously categorize individuals according to the parties they support, even when explicit cooperation and antagonism are absent, and if party support is sufficiently powerful to decrease participants’ categorization by an orthogonal but typically-diagnostic alliance cue . Evidence was found for both: Participants spontaneously and implicitly kept track of who supported which party, and when party cross-cut race—such that the race of targets was not predictive of party support—categorization by race was dramatically reduced. To verify that these results reflected the operation of a cognitive system for modifying the activation of alliance categories, and not just socially-relevant categories in general, an identical set of studies was also conducted with in which party was either crossed with sex or age . As predicted, categorization by party occurred to the same degree, and there was no reduction in either categorization by sex or by age. All effects were replicated across two sets of between-subjects conditions. These studies provide the first direct empirical evidence that party politics engages the mind’s systems for detecting alliances and establish two important social categorization phenomena: that categorization by age is, like sex, not affected by alliance information and that political contexts can reduce the degree to which individuals are represented in terms of their race.

We examine the ontogeny and phylogeny of object and fantasy play from a functional perspective. Each form of play is described from an evolutionary perspective in terms of its place in the total time and energy budgets of human and nonhuman juveniles. As part of discussion of functions of play, we examine sex differences, particularly as they relate to life in the environment of evolutionary adaptedness and economic activities of human and nonhuman primates. Object play may relate to foraging activities. (...) Although fantasy play has been viewed as limited to humans, we speculate that certain types of fantasy play may be present in some nonhuman primates. Fantasy play may enable juveniles to see situations from different perspectives. We conclude that fantasy play may have immediate effects and object play may have deferred effects. (shrink)

Here I will develop a naturalistic account of epistemic reflection and its significance for epistemology. I will first argue that thought, as opposed to mere information processing, requires a capacity for cognitive self-regulation. After discussing the basic capacities necessary for cognitive self-regulation of any kind, I will consider qualitatively different kinds of thought that can emerge when the basic capacities enable the creature to interiorize a form of social cooperation. First, I will discuss second-personal cooperation and the kind of thought (...) that emerges from its interiorization. Then, I will discuss third-personal cooperation and the kind of thought that emerges from its interiorization. We will see that epistemic reflection is the interiorized version of interpersonal argumentation, which is the epistemic component of third-personal cooperation. In developing this account, I will draw heavily on the work of Michael Tomasello and other cognitive scientists advocating the “social intentionality hypothesis”. However, I will show how work done in the defeasible reasoning tradition can provide us with a deeper explanation of some claims made by advocates of the social intentionality hypothesis. Additionally, we will see that work done on social intentionality can help us better understand the significance of knowledge and justification as understood by the defeasible reasoning tradition. We will see that the social intentionality hypothesis and the defeasible reasoning tradition are mutually illuminating. By drawing equally on both, I will provide a novel account of the foundations of knowledge. (shrink)

Bering's argument that human beings are endowed with a cognitive system dedicated to forming illusory representations of psychological immortality relies on the claim that children's beliefs in the afterlife are not the result of religious teaching. We suggest four reasons why this claim is unsatisfactory.

Did protolanguage users use discrete words that referred to objects, actions, locations, etc., and then, at some point, combine them; or on the contrary did they have words that globally indexed whole semantic complexes, and then come to divide them? Our answer is: early humans were forming language units consisting of global and discrete dimensions of semiosis in dynamic opposition. These units of thinking-for-speaking, or ‘growth points’ (GPs) were, jointly, analog imagery (visuo-spatio-motoric) and categorically-contrastive (-emic) linguistic encodings. This discrete-global duality (...) was a new mode of embodied cognition that enabled thinking and acting in new ways: the dawn of protolanguage. Where did this mode of cognition come from? We have some suggestions based on the hypothesis that gestures gained the power to orchestrate actions, manual and vocal, with significances other than those of the actions themselves, giving rise to cognition framed in the proposed dual terms. Note, however, our proposal is not one of the ‘gesture-first’ theories of language origins. Such theories predict what did not evolve: a language of pantomime; rather than what did evolve: an integrated system of synchronized gestures and spoken forms. GP theory is an account of the cognition underlying such an integrated system. A scenario for the evolutionary selection of this cognitive mode is ‘Mead’s Loop’, a model in which one’s cognition is enriched by one’s own gestures, insofar as they are objects in social interactions.

In “Causality and Determination”, Anscombe stressed that, in her view, physical determinism and free action were incompatible. As the relevant passage suggests, her espousal of incompatibilism was not merely due to specific features of human ‘ethical’ freedom, but due to general features of agency, intentionality, and voluntariness. For Anscombe went on to tentatively suggest that lack of physical determination was required for the intentional conduct of animals we would not classify as ‚free‘, too. In this paper, I examine three different (...) lines of argument to establish Anscombe’s latter suggestion, which are based on general considerations about the causal efficacy of psychological-agential phenomena, the nature of agency, and the specific features of intentional agency. I start with Anscombe’s own claim from “The Causation of Action” that microphysical determinism would make psychological and personal phenomena epiphenomenal, before I turn to the view of ‘Agency Incompatibilism’, that genuine agency requires the absence of antecedent necessitation, and, lastly, to concerns about some crucial features of intentional agency which we find in both human and animal agents.
