Imitation, the replication of observed behaviors, has been proposed as the crucial social learning mechanism for the generation of humanlike cultural complexity. To date, the single published experimental microsociety study that tested this hypothesis found no advantage for imitation. In contrast, the current paper reports data in support of the imitation hypothesis. Participants in “microsociety” groups built weight-bearing devices from reed and clay. Each group was assigned to one of four conditions: three social learning conditions and one asocial learning control (...) condition. Groups able to observe other participants building their devices, in contrast to groups that saw only completed devices, show evidence of successive improvement. These results are consistent with the hypothesis that imitation is required for cumulative cultural evolution. This study adds crucial data for understanding why imitation is needed for cultural accumulation, a central defining feature of our species. (shrink)

We present an account of semantics that is not construed as a mapping of language to the world but rather as a mapping between individual meaning spaces. The meanings of linguistic entities are established via a “meeting of minds.” The concepts in the minds of communicating individuals are modeled as convex regions in conceptual spaces. We outline a mathematical framework, based on fixpoints in continuous mappings between conceptual spaces, that can be used to model such a semantics. If concepts are (...) convex, it will in general be possible for interactors to agree on joint meaning even if they start out from different representational spaces. Language is discrete, while mental representations tend to be continuous—posing a seeming paradox. We show that the convexity assumption allows us to address this problem. Using examples, we further show that our approach helps explain the semantic processes involved in the composition of expressions. (shrink)

Gergely and Csibra's theory, known as "natural pedagogy theory", is meant to explain how infants fast-learn generic knowledge from adults. In this paper, my goal is to assess the explanatory import of this theory in a particular case, namely the phenomena known as "A-not-B errors". I first propose a clarification of natural pedagogy theory's fundamental hypotheses. Then, I describe Topál et al.'s (Science, 321, 1831-1834, 2008) experiments, which consist in applying natural pedagogy theory's framework to the A-not-B errors. Finally, I (...) show that natural pedagogy theory, in its actual stage of development, does not suffice to choose between various interpretations of Topál et al.'s experimental results. (shrink)

Skepticism toward the existence of neonatal differential imitation is fostered by views that assign it an excessive significance, making it foundational for social cognition. Moreover, a misleading theoretical framework may generate unwarranted expectations about the kinds of findings experimentalists are supposed to look for. Hence we propose a theoretical analysis that may help experimentalists address the empirical question of whether early differential imitation really exists. We distinguish three models of early imitation. The first posits automatic visuo-motor links evolved for sociocognitive (...) functions and we call it Genetically Programmed Direct Matching. The second is Meltzoff and Moore’s Active Intermodal Matching, which postulates a comparison between the acts of self and other. The third is the alternative we propose and we call it “Association by Similarity Theory”, as it relies on the tacit functioning of this domain-general process. AST describes early imitation merely as the differential induction or elicitation of behaviors that already tend to occur spontaneously. We focus on the contrast between AIM and AST, and argue that AST is preferable to AIM for two reasons. First, AST is more parsimonious and more plausible, especially because it does not require infants to be able to recognize self-other similarities. Second, whereas the extant findings tend to disqualify AIM, AST can account for them adequately. Furthermore, we suggest that AST has the potential to give new impulse to empirical research because it discriminates promising lines of inquiry from unproductive ones. (shrink)

In contemporary philosophy of the cognitive sciences, proponents of the ‘Hypothesis of Extended Cognition’ have focused on demonstrating how cognitive processes at times extend beyond the boundaries of the human body to include external physical devices. In recent years the HEC framework has been put to use in cases of “socially” extended cognition. The guiding intuition in this paper is that exploring the cognitive incorporations of genuinely social elements may advance HEC debates. The paper provides an analysis of emotion regulation (...) in ‘dyadic synchronic interaction’ between infant and caretaker and argues that some ‘socially extended’ cases of cognition cannot be captured with the HEC. Instead, the ‘Hypothesis of Emergent Extended Cognition’ is introduced that complements the HEC and helps in understanding how cognitive properties are sometimes irreducibly emergent, non-programmed properties of coupled social systems. It will be concluded that operating with the HEEC leads to both a more precise grip on the explanandum and to a more robust explanans. (shrink)

In this paper, we draw on developmental findings to provide a nuanced understanding of background emotions, particularly those in depression. We demonstrate how they reflect our basic proximity (feeling of interpersonal connectedness) to others and defend both a phenomenological and a functional claim. First, we substantiate a conjecture by Fonagy & Target (International Journal of Psychoanalysis 88(4):917–937, 2007) that an important phenomenological aspect of depression is the experiential recreation of the infantile loss of proximity to significant others. Second, we argue (...) that proximity has a particular cognitive function that allows individuals to morph into a cohesive dyadic system able to carry out distributed emotion regulation. We show that elevated levels of psychological suffering connected to depressive background emotions may be explained not only in terms of a psychological loss, but also as the felt inability to enter into dyadic regulatory relations with others—an experiential constraint that decreases the individual’s ability to adapt to demanding situations.

This commentary focuses on the parts of psychological game theory dealing with preference, as illustrated by team reasoning, and supports the conclusion that these theoretical notions do not contribute above and beyond existing theory in understanding social interaction. In particular, psychology and games are already bridged by a comprehensive, formal, and inherently psychological theory, interdependence theory (Kelley & Thibaut 1978; Kelley et al. 2003), which has been demonstrated to account for a wide variety of social interaction phenomena.

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 principal aim of this paper is to analyze the relationship between intersubjectivity and grammar. We argue that intersubjectivity represents, on the one hand, a prerequisite for the development of language as a symbolic system, and therefore also for the development of grammar. Furthermore, we attempt to show that language, and especially grammar, codify intersubjectivity. That is to say, grammatical constructions represent the intersubjective interactions that situated agents maintain in different pragmatic contects. We call this phenomenon the meta-representational capacity of (...) language. Our main object of analysis is the development of the ditransitive construction in the Spanish language. The evolution of this construction makes it clear that there is an important correlation between the degree of complexity of the codified intersubjective interaction and grammatically obligatory nature and the prominence of the grammatical construction that codifies it: the greater the complexity, the greater its obligatoriness, and vice versa.

What is the role of language in social interaction? What does language bring to social encounters? We argue that language can be conceived of as a tool for interacting minds, enabling especially effective and flexible forms of social coordination, perspective-taking and joint action. In a review of evidence from a broad range of disciplines, we pursue elaborations of the language-as-a-tool metaphor, exploring four ways in which language is employed in facilitation of social interaction. We argue that language dramatically extends the (...) possibility-space for interaction, facilitates the profiling and navigation of joint attentional scenes, enables the sharing of situation models and action plans, and mediates the cultural shaping of interacting minds.

How is linguistic communication possible? How do we come to share the same meanings of words and utterances? One classical position holds that human beings share a transcendental “platonic” ideality independent of individual cognition and language use (Frege 1948). Another stresses immanent linguistic relations (Saussure 1959), and yet another basic embodied structures as the ground for invariant aspects of meaning (Lakoff and Johnson 1999). Here we propose an alternative account in which the possibility for sharing meaning is motivated by four (...) sources of structural stability: 1) the physical constraints and affordances of our surrounding material environment, 2) biological constraints of our human bodies, 3) social normative constraints of culture and society, and 4) the local history of social interactions. These structures and constraints interact in dynamical ways in actual language usage situations: local dialogical and social dynamics motivate and stabilize the profiling of a conceptual space already highly structured by our shared biology, culture, and environment. We will substantiate this perspective with reference to recent studies in experimental pragmatics and semiotics in which participants interact linguistically to solve cooperative tasks. Three main cases will be considered: The dynamic grounding of linguistic categories, the construction of conceptual models to relate entities in a scene, and the construction of shared conceptual scales for assessing and appraising subjective experiences.

In this paper, we distinguish between a number of different phenomena that have been called imitation, and identify one form—a high fidelity mechanism for social learning—considered to be crucial for the development of language. Subsequently, we consider a common claim in the language evolution literature, which is that prior to the emergence of vocal language our ancestors communicated using a sophisticated gestural protolanguage, the learning of some parts of which required manual imitation. Drawing upon evidence from recent work in neuroscience, (...) primatology, and archeology, we argue that while gestural communication undoubtedly played a crucial role in language evolution, the grounds for thinking that manual imitation did are currently unconvincing.

It is widely believed that what distinguishes the social cognition of humans from that of other animals is the belief–desire psychology of four–year–old children and adults (so–called theory of mind). We argue here that this is actually the second ontogenetic step in uniquely human social cognition. The first step is one year old children's understanding of persons as intentional agents, which enables skills of cultural learning and shared intentionality. This initial step is ‘the real thing’ in the sense that it (...) enables young children to participate in cultural activities using shared, perspectival symbols with a conventional/normative/reflective dimension—for example, linguistic communication and pretend play—thus inaugurating children's understanding of things mental. Understanding beliefs and participating in collective intentionality at four years of age—enabling the comprehension of such things as money and marriage—results from several years of engagement with other persons in perspective–shifting and reflective discourse containing propositional attitude constructions.

I introduce the special issue by: (1) outlining something of the relationship between mainstream cognitive science and the study of nonhuman primate cognition; (2) providing a brief overview of the scientific study of primate cognition and how the papers of this special issue fit into that scientific paradigm; and (3) explicating my own views about the relationship between nonhuman primate cognition and human cognition.

We propose a mentalistic and nativist view of human early mental and social life and of the ontogeny of mindreading. We define the mental state of sharedness as the primitive, one-sided capability to take one's own mental states as mutually known to an i nteractant. We argue that this capability is an innate feature of the human mind, which the child uses to make a subjective sense of the world and of her actions. We argue that the child takes all (...) of her mental states as shared with her caregivers. This a llows her to interact with her caregivers in a mentalistic way from the very beginning and provides the grounds on which the later maturation of mindreading will build. As the latter process occurs, the child begins to understand the mental world in terms of differences between the mental states of different agents; subjectively, this also corresponds to the birth of privateness. ?

We set out an account of how self-domestication plays a crucial role in the evolution of language. In doing so, we focus on the growing body of work that treats language structure as emerging from the process of cultural transmission. We argue that a full recognition of the importance of cultural transmission fundamentally changes the kind of questions we should be asking regarding the biological basis of language structure. If we think of language structure as reflecting an accumulated set of (...) changes in our genome, then we might ask something like, “What are the genetic bases of language structure and why were they selected?” However, if cultural evolution can account for language structure, then this question no longer applies. Instead, we face the task of accounting for the origin of the traits that enabled that process of structure-creating cultural evolution to get started in the first place. In light of work on cultural evolution, then, the new question for biological evolution becomes, “How did those precursor traits evolve?” We identify two key precursor traits: the transmission of the communication system through learning; and the ability to infer the communicative intent associated with a signal or action. We then describe two comparative case studies—the Bengalese finch and the domestic dog—in which parallel traits can be seen emerging following domestication. Finally, we turn to the role of domestication in human evolution. We argue that the cultural evolution of language structure has its origin in an earlier process of self-domestication. (shrink)

On the classical instrumental view, practical reason is an all-things-considered enterprise, concerned not merely with identifying and evaluating appropriate means to the realization of ends construed as uncriticizable, but also with coordinating achievement of their sum. The concept of a totality of ranked concerns is the cornerstone of the theory of utility. This paper discusses some of the ways that practical reasoning, on the ground, is not instrumental in this sense. The paper will demonstrate that some of what goes on (...) by way of practical reasoning on the ground involves a certain simple inference schema—to be called “imitative reasoning”—that involves mobilization of what has been alternately referred to as archetypes, scripts, stereotypes and schemas including most importantly self-schemas or self-concepts. Imitative reasoning, as the paper will argue, is especially hostile to deliberations that involve the sorts of tradeoffs that applications of utility theory routinely advise. It is therefore no expression or realization, however imperfect, of the notion of maximization. What is more, this framework routinely evokes as authoritative the norms of privilege, however removed from or irrelevant to the matter at hand, which might be as simple as where to go for dinner. For it is the basis of—among other things—class and race consciousness. Furthermore, it is highly subject to manipulation by the unscrupulous; such as, for example, by those who market consumer goods, especially to children. For this form of reasoning is employed so as to protect or enhance self-concepts: imitative reasoning is a form of motivated reasoning. Laying it out in schema form will shed light on the sort of reasoning processes that transpire in many cases of cognitive dissonance reduction. (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.

Contrary to Vaesen, we argue that a small number of key traits are sufficient to explain modern human tool use. Here we outline and defend the cultural intelligence (CI) hypothesis. In doing so, we critically re-examine the role of social transmission in explaining human tool use.

This paper presents a series of 4 single subject experiments aimed to investigate whether children with autism show more social engagement when interacting with the Nao robot, compared to a human partner in a motor imitation task. The Nao robot imitates gross arm movements of the child in real-time. Different behavioral criteria (i.e. eye gaze, gaze shifting, free initiations and prompted initiations of arm movements, and smile/laughter) were analyzed based on the video data of the interaction. The results are mixed (...) and suggest a high variability in reactions to the Nao robot. The results are as follows: For Child2 and Child3, the results indicate no effect of the Nao robot in any of the target variables. Child1 and Child4 showed more eye gaze and smile/laughter in the interaction with the Nao robot compared to the human partner and Child1 showed a higher frequency of motor initiations in the interaction with the Nao robot compared to the baselines, but not with respect to the human-interaction. The robot proved to be a better facilitator of shared attention only for Child1. Keywords: human-robot interaction; assistive robotics; autism. (shrink)

The present study explores the idea that human linguistic communication co-opted a pre-existing population-wide behavioural system that was shared among social group members and whose structure reflected the structure of the environment. This system is hypothesized to have emerged from interactions among individuals who had evolved the capacity to imitate arbitrary, functionless behaviour. A series of agent-based computer simulations test the separate and joint effects of imitation, pattern completion behaviour, environment structure and level of social interaction on such a population-wide (...) behavioural system. The results support the view that a system that could be co-opted for linguistic communication might arise in a population of agents equipped with arbitrary imitation for the purposes of pattern completion interacting in certain kinds of structured environments. Such pre-linguistic behavioural system could have bootstrapped communication and paved the way for biological capacities widely believed to be necessary for communication, such as shared intentionality and symbolicity, to evolve.

The neurocognitive structure of the acting self has recently been widely studied, yet is still perplexing and remains an often confounded issue in cognitive neuroscience, psychopathology and philosophy. We provide a new systematic account of two of its main features, the sense of agency and the sense of ownership, demonstrating that although both features appear as phenomenally uniform, they each in fact are complex crossmodal phenomena of largely heterogeneous functional and representational levels. These levels can be arranged within a gradually (...) evolving, onto- and phylogenetically plausible framework which proceeds from basic non-conceptual sensorimotor processes to more complex conceptual and meta-representational processes of agency and ownership, respectively. In particular, three fundamental levels of agency and ownership processing have to be distinguished: The level of feeling, thinking and social interaction. This naturalistic account will not only allow to “ground the self in action”, but also provide an empirically testable taxonomy for cognitive neuroscience and a new tool for disentangling agency and ownership disturbances in psychopathology.

Verb tenses play an important role in managing deictic relations between the narrator, the audience and the events happening in the story world. Across languages, the Simple Past is considered the conventional story-telling tense, reflecting the prototypical deictic configuration of stories in which the narrator is positioned at some distance from the events unfolding in the story. The Simple Present, on the other hand, is considered a marked option for narration, assumed to automatically result in a shift to a subjective (...) perspective. This paper reports on an analysis of a corpus made up of Dutch fictional short stories, news reports and feature articles. The results suggest that conventions for use and interpretation of verb tenses in narrative contexts are in fact genre-dependent. In the news genres, the Simple Present tense dominated in narration. This did not automatically result in a subjective mode or narration, but was naturally used to express a default narration of story events that temporally overlap with the temporal deictic center of the communicative ground. These findings suggest that previous analyses of verb tenses in relation to narration reflect an over-generalization based on the situational characteristics of prototypical narrative genres such as literary fiction and personal anecdotes.

One of the central explananda in the debate on social cognition is the interpretation of other people in terms of reasons for action. There is a growing dissatisfaction among participants in the debate concerning the descriptive adequacy of the traditional belief-desire model of action interpretation. Applying this model as an explanatory model at the subpersonal level threatens to leave the original explanandum largely unarticulated. Against this background we show how Brandom’s deontic scorekeeping model can be used as a valuable descriptive (...) tool for making folk psychology explicit. Following Brandom’s non-formalist and non-mentalistic account of reason discourse, we suggest that the process of making sense of others is best captured as proceeding from a ‘factive’ baseline. According to this picture the ascription of beliefs and desires is not the default interpretation strategy, but rather the result of prior scaffolding of the agent’s deontic score. We close by discussing Brandom’s model in the light of empirical findings on the ontogeny of reason attribution. (shrink)

Many philosophers working today on the normativity of language have concluded that linguistic activity is not a matter of rule following. These conversations have been framed by a conception of linguistic normativity with roots in Wittgenstein and Kripke. In this paper I use conceptual resources developed by the classical American pragmatists and their descendants to argue that punctate linguistic acts are governed by rules in a sense that has been neglected in the recent literature on the normativity of language. In (...) the course of arguing for this conclusion I defend a Kantian conception of rationality as rule-obeying activity, and I argue that this conception is compatible with a naturalistic understanding of ourselves as rational beings governed by rules of thought and action.

What kind mechanisms one deems central for the evolutionary process deeply influences one's understanding of the nature of organisms, including cognition. Reversely, adopting a certain approach to the nature of life and cognition and the relationship between them or between the organism and its environment should affect one's view of evolutionary theory. This paper explores this reciprocal relationship in more detail. In particular it argues that the view of living and cognitive systems, especially humans, as deeply integrated beings embedded in (...) and transformed by their genetic, epigenetic, behavioral, ecological, socio-cultural and cognitive-symbolic legacies calls for an extended evolutionary synthesis that goes beyond either a theory of genes juxtaposed against a theory of cultural evolution and or even more sophisticated theories of gene-culture coevolution and niche construction. Environments, particularly in the form of developmental environments, do not just select for variation, they also create new variation by influencing development through the reliable transmission of non-genetic but heritable information. This paper stresses particularly views of embodied, embedded, enacted and extended cognition, and their relationship to those aspects of extended inheritance that lie between genetic and cultural inheritance, the still gray area of epigenetic and behavioral inheritance systems that play a role in parental effect. These are the processes that can be regarded as transgenerational developmental plasticity and that I think can most fruitfully contribute to, and be investigated by, developmental psychology.

Experiences of art involve exercise of ordinary cognitive and perceptual capacities but in unique ways. These two features of experiences of art imply the mutual importance of aesthetics and cognitive science. Cognitive science provides empirical and theoretical analysis of the relevant cognitive capacities. Aesthetics thus does well to incorporate cognitive scientific research. Aesthetics also offers philosophical analysis of the uniqueness of the experience of art. Thus, cognitive science does well to incorporate the explanations of aesthetics. This paper explores this general (...) framework of expansionism : a research strategy that suggests that the explanatory goals and resources of both aesthetics and cognitive science should expand to include those of the other. Two relations are considered. First, what is the relation between aesthetics and more traditional cognitive science? Second, what is the relation between aesthetics and new developments in cognitive science that de-emphasize mental representation and emphasize body and action? (shrink)

This paper argues that the faculty of language comes essentially for free in evolutionary terms, by grace of a capacity shared with some evolutionarily quite distantly related animals for deliberatively planning action in the world. The reason humans have language of a kind that animals do not is because of a qualitative difference in the nature of human plans rather than anything unique to language.

Downes, Gerrans, and Sutton all raise important issues for the account of human social learning and cooperation developed in The Evolved Apprentice. Downes suggests that I have bought too uncritically into the view that hunting was economically critical to forager life; I remain unpersuaded, while conceding something to the alternative view that hunting was signaling. Downes also suggests that I consider extending the evolved apprentice model to contemporary issues in social epistemology; I wonder whether that might make the model so (...) general that it loses explanatory force. Gerrans probes the model on the relationship between social learning and imitation; I respond by arguing that imitation became important relatively late in the human social learning career, probably via learning to communicate via gesture. Sutton wonders whether the model of social learning developed is too intellectualist and individualist; I respond by emphasizing the varied task demands in different domains, and the change over time of the different elements involved in social learning.

The idea that natural language grammar and planned action are relatedsystems has been implicit in psychological theory for more than acentury. However, formal theories in the two domains have tendedto look very different. This article argues that both faculties sharethe formal character of applicative systems based on operationscorresponding to the same two combinatory operations, namely functional composition and type-raising. Viewing them in thisway suggests simpler and more cognitively plausible accounts of bothsystems, and suggests that the language faculty evolved in the (...) speciesand develops in children by a rather direct adaptation of a moreprimitive apparatus for planning purposive action in the world bycomposing affordances of objects or tools. Theknowledge representation that underlies such planning is alsoreflected in the natural language semantics of tense, mood, andaspect, which the paper begins by arguing provides the key tounderstanding both systems.

The portrayal of the actions of fictive characters for purposes of entertainment is a familiar phenomenon. Theories that seek to explain why we are attracted to such fictions and whether we learn from them have produced no consensus and no adequate overall account. In this paper, we present the hypothesis that entertainment relies on cognitive adaptations for pretend play. As a simplified model system, we draw on our field study of children's chase play, which is characterized by an elementary form (...) of pretense. The children pretend, at first without consciously representing their pretense, to be chased by predators. The details of this behavior, widespread among mammals, indicate that the biological function of the game may be to train predator-evasion strategies. Chase play, we suggest, evolved in early mammals because it enabled cheap and plentiful resources to be used to train strategies for events that are rare, dangerous, and expensive. More generally, we argue that pretense is used to access spaces of possible actions in order to locate and practice new strategies. It relies on the creation of a simulated scenario and requires sophisticated source monitoring. The simulation is experienced as intrinsically rewarding; boredom is a design feature to motivate the construction of a more appropriate pedagogical situation, while the thrill of play signals optimal learning conditions. The conscious narrative elaboration of chase games involves an elementary form of role play, where we propose a virtual agent is created that tracks and acts on the memories required for coherent action within the simulation. These complex if familiar design features, we suggest, provide a minimalist functional and adaptationist account of the central features of entertainment: that it is fun, that it involves us imaginatively and emotionally, and that it has a tacit pedagogical effect. The model provides a principled and testable account of fiction-based entertainment grounded in evolutionary and cognitive processes. (shrink)

In this article we frame a set of important issues in the emerging field of Mind, Brain, and Education in terms of three broad headings: methods, models, and morality. Under the heading of methods we suggest that the need for synthesis across scientific and practical disciplines entails the pursuit of usable knowledge via a catalytic symbiosis between theory, research, and practice. Under the heading of models the goal of producing usable knowledge should shape the construction of theories that provide comprehensive (...) accounts of human learning and development spanning multiple levels of analysis. Under the heading of morality usable knowledge must be put to good use: Its application and dissemination ought to be infused with moral considerations gleaned from dialogue among all those potentially affected. Generally, the field should be shaped not only by its constituent scientific disciplines but also by its applications to education and learning. Thus we argue for the adoption of a kind of pragmatism that would be best actualized by building research-school collaborations between researchers and practitioners. (shrink)

This paper begins by calling attention to a puzzling feature of our deep past: an apparent mis-match between morphological evolution in our lineage, including the expansion of our brain and neocortex, and changes in material culture. Three ideas might explain this mis-match. The apparent mis-match is an illusion: change in material culture is indeed driven by biological evolution, but of a kind difficult to identify in the fossil record; the mismatch is caused by the fact that material culture is sensitive (...) to the social and demographic environment, not just the native cognitive capacities of individual agents. Innovation and its uptake is more reliable in larger social worlds. The mis-match is made possible by adaptive phenotypic plasticity; in particular, cognitive plasticity. Just as material culture evolves through cumulative cultural learning, so too do cognitive skills, including ones which make innovations in, and the transmission of, material culture more efficient. This paper is targeted on the second of these ideas, and distinguishes three different versions of the view that increases in social scale support increases in the complexity of material culture. Those are: cultural selection is more efficient in larger social worlds; larger social worlds support more specialisation, which in turn supports a more complex material culture; cultural learning is more efficient in larger social worlds. The paper argues that the first two of these pathways are probably more important than the third in explaining otherwise puzzling features of the archaeological and ethnographic record. (shrink)

In this article, I present a substantive proposal about the timing and nature of the final stage of the evolution of full human language, the transition from so-called “protolanguage” to language, and on the origins of a simple protolanguage with structure and displaced reference; a proposal that depends on the idea that the initial expansion of communicative powers in our lineage involved a much expanded role for gesture and mime. But though it defends a substantive proposal, the article also defends (...) and illustrates a methodological proposal too. I argue that language is a special case of a more general phenomenon—cumulative cultural evolution—and while we rarely have direct information about communication, we have more direct information about the cumulative cultural evolution of technical skill, ecological strategies, and social complexity. These same factors also enable us to make a reasonable estimate of the intergenerational social learning capacities of these communities and of the communicative demands these communities face. For example, we can, at least tentatively, identify forms of cooperation that are stable only if third party information is transmitted widely, cheaply, and accurately. So we can use these more direct markers of information accumulation to locate, in broad terms, the period in our evolutionary history during which we became lingual. (shrink)

In this article I develop a big picture of the evolution of human cooperation, and contrast it to an alternative based on group selection. The crucial claim is that hominin history has seen two major transitions in cooperation, and hence poses two deep puzzles about the origins and stability of cooperation. The first is the transition from great ape social lives to the lives of Pleistocene cooperative foragers; the second is the stability of the social contract through the early Holocene (...) transition to complex hierarchical societies. The first of these transitions is driven, at least initially, by individual advantage: cooperation paid off for individual foragers, initially through mutualist interaction, then through reciprocation. This argument leads to a reanalysis of the role of violence and the nature of the freeriding threat to cooperation. But the conditions that select for cooperative individuals in the Pleistocene were eroded in the Pleistocene–Holocene transition. So we need an alternative account of the survival, and indeed the expansion, of cooperation in the Holocene. Group selection driven by intercommunal conflict really may well be central to this second transition. (shrink)

Debates in animal cognition are frequently polarized between the romantic view that some species have human-like causal understanding and the killjoy view that human causal reasoning is unique. These apparently endless debates are often characterized by conceptual confusions and accusations of straw-men positions. What is needed is an account of causal understanding that enables researchers to investigate both similarities and differences in cognitive abilities in an incremental evolutionary framework. Here we outline the ways in which a three-dimensional model of causal (...) understanding fulfills these criteria. We describe how this approach clarifies what is at stake, illuminates recent experiments on both physical and social cognition, and plots a path for productive future research that avoids the romantic/killjoy dichotomy.
