An important part of our Theory of Mind—the ability to reason about other people's unobservable mental states—is the ability to attribute false beliefs to others. We investigated whether processing these false beliefs, as well as similar but nonmental representations, is reliant on language. Participants watched videos in which a protagonist hides a gift and either takes a photo of it or writes a text about its location before a second person inadvertently moves the present to a different location, thereby rendering (...) the belief and either the photo or text false. At the same time, participants performed either a concurrent verbal interference task (rehearsing strings of digits) or a visual interference task (remembering a visual pattern). Results showed that performance on false belief trials did not decline under verbal interference relative to visual interference. We interpret these findings as further support for the view that language does not form an essential part of the process of reasoning online (“in the moment”) about false beliefs. (shrink)

I accept the main thesis of the article according to which representation of knowledge is more basic than representation of belief. But I question the authors’ contention that humans' unique capacity to represent belief does not underwrite the capacity for the accumulation of cultural knowledge.

1. Philosophical arguments (Schweikard & Schmid, 2013) and empirical evidence (Tomasello, Carpenter, Call, Behne, & Moll, 2005) support the idea that the capacity to engage in joint actions is a ke...

To corroborate the music and social bonding hypothesis, we propose that future investigations isolate specific components of social bonding and consider the influence of context. We deconstruct and operationalize social bonding through the lens of social psychology and provide examples of specific measures that can be used to assess how the link between music and sociality varies by context.

Language and Theory of Mind come together in communication, but their relationship has been intensely contested. I hypothesize that pragmatic markers connect language and Theory of Mind and enable their co-development and co-evolution through a positive feedback loop, whereby the development of one skill boosts the development of the other. I propose to test this hypothesis by investigating two types of pragmatic markers: demonstratives and articles. Pragmatic markers are closed-class words that encode non-representational information that is unavailable to consciousness, but (...) accessed automatically in processing. These markers have been associated with implicit Theory of Mind because they are used to establish joint attention and mark shared knowledge. Here I develop a theoretical account of how joint attention is the basis for children’s later tracking of common ground. The developmental path from joint attention to common ground parallels language change, with demonstrative forms giving rise to definite articles. This parallel opens the possibility of modelling the emergence of Theory of Mind in human development in tandem with its routinization across language communities and generations of speakers. I therefore propose that, in order to understand the relationship between language and Theory of Mind, we should study pragmatics at three parallel timescales: during language acquisition, language use, and language change.

It is generally recognized that descriptive and normative individualism are logically independent theses. This paper defends the stronger view that recognition of the falsehood of descriptive individualism is crucial to understanding the evolutionary and developmental basis of normative individualism. The argument given for this is not analytic; rather, it is based on empirical generalizations about the evolution of markets with specialized labor, about the nature of information processing in large markets, and about the socialization of human children.

Distinguishing intentional behavior from accidental behavior is a crucial component of social cognition and a major developmental achievement. It has often been assumed that developmental changes in intentional reasoning result from a gradual sophistication in the ability to discern intentions in action. We take issue with this notion, demonstrating that data from cognitive, developmental, and social psychology are more consistent with the hypothesis that it is instead a gradual sophistication in the ability to understand accidents that drives developmental change.

This paper outlines how the focus on how communicative signals might emerge and how the capacity to interpret them might develop, does not yet explain what type of motivation is required to actually deal with those signals. Without the consistent production of appropriate responses to the production of communicative signals, there would be no point in producing any signal. If language is a tool to accomplish things with others, we need to understand what would lead to cooperation. The first step (...) consists in avoiding the blind belief that all cooperation requires some prosocial attitude. A great deal of cooperation can occur while each participant in the interaction is selfishly attempting to maximize their own benefits or minimizing damaging consequences.I describe how different types of turn-taking can be achieved via different levels of cognitive complexity and how interpretive turn-taking requires a great deal of cognitive abilities that great apes possess. Finally, I provide empirical evidence of social manipulation in non-human primates. Given our awareness of the occurrence of social manipulation during cooperation among human adults, it seems necessary to reconsider to what degree human communication and language evolution require unique prosocial motivations.

There is converging evidence that over the course of the second year children become good at various fairly sophisticated forms of pro-social activities, such as helping, informing and comforting. Not only are toddlers able to do these things, they appear to do them routinely and almost reliably. A striking feature of these interventions, emphasized in the recent literature, is that they show precocious abilities in two different domains: they reflect complex ‘ theory of mind’ abilities as well as ‘altruistic motivation’. (...) Our aim in this paper is to present a theoretical hypothesis that bears on both kinds of developments. The suggestion is that children’s ‘instrumental helping’ reflects their budding understanding of practical reasons. We can put the basic idea in the familiar terminology of common coding : toddlers conceive of the goals of others’ actions in the same format as the goals of their own actions: in terms of features of their situation that provide us with reasons to act.

Social thinkers often use the concept of intersubjectivity to mark out a problem of theoretical sociology: If people are unable to look into each others' minds, why do they often understand each other nonetheless? This issue has been debated extensively by philosophers and sociologists in three largely disconnected discourses. The article investigates the three discourses for isolable ideas that can be fitted into a sociological answer to the problem of intersubjectivity. An interactional solution, fully coherent with key insights from the (...) discourses, is offered at the end of the article. Its main point is to identify coordinative interactional mechanisms that compel participants to "make themselves understandable" vis-à-vis their interaction partners. (shrink)

Many believe that moral education can cause moral progress. At first glance, this makes sense. A major goal of moral education is the improvement of the moral beliefs, values and behaviors of young people. Most would also consider all of these improvements to be important instances of moral progress. Moreover, moral education is a form of social learning, and there are good reasons to think that social learning processes shape episodes of progressive moral change. Despite this, we argue that instead (...) of being a cause of moral change, the main effect of moral education is often to provide stability or continuity. In addition, we will argue that even when the conditions are right for moral education to contribute to moral change, it is far from clear that the resulting changes will always, or even most of the time, end up being progressive.

Children improve at word learning during the 2nd year of life—sometimes dramatically. This fact has suggested a change in mechanism, from associative learning to a more referential form of learning. This article presents an associative exemplar-based model that accounts for the improvement without a change in mechanism. It provides a unified account of children's growing abilities to (a) learn a new word given only 1 or a few training trials (“fast mapping”); (b) acquire words that differ only slightly in phonological (...) form; (c) generalize word meanings preferentially along particular dimensions, such as object shape (the “shape bias”); and (d) learn 2nd labels for already-named objects, despite a persisting resistance to doing so (“mutual exclusivity”). The model explains these improvements in terms of increased attention to relevant aspects of form and meaning, which reduces memory interference. The interaction of associations and reference in word learning is discussed. (shrink)

In Why We Cooperate, Tomasello addresses the problem of human uniqueness, which has become the focus for a lot of recent research at the frontier between the Humanities and the Life Sciences. Being both a developmental psychologist and a primatologist, Tomasello is especially well suited to tackle the subject, and the present book is the most recent one in a series of books and papers by himself and his colleagues. Tomasello’s basic position is squarely a dual-inheritance account, in which human (...) uniqueness is explained both through genetics and through culture. The main idea is that the phylogenetic specificity of humankind rests in its species-specific adaptation for sociability. The account offered by Tomasello contrasts human cooperation and altruism with nonhuman primate competition, and proposes that human altruism leads to shared intentionality. The evolutionary explanation Tomasello offers is that human ancestors were led through some kind of selection pressure to common foraging leading to collaboration and sharing. After outlining Tomasello’s position as it is described in the book, as well as the comments by Dweck, Spelke, Silk, and Skyrms which follow, I discuss Tomasello’s thesis, noting a few problems with his approach. These criticisms are based on his own work and on a number of his own other books and papers, as well as on other relevant work in the domain. (shrink)

The study of animal culture is a flourishing field, with culture being recorded in a wide range of taxa, including non-human primates, birds, cetaceans, and rodents. In spite of this research, however, the concept of culture itself remains elusive. There is no universally assented to concept of culture, and there is debate over the connection between culture and related concepts like tradition and social learning. Furthermore, it is not clear whether culture in humans and culture in non-human animals is really (...) the same thing, or merely loose analogues that go by the same name. The purpose of this paper is to explicate core desiderata for a concept of culture and then to construct a concept that meets these desiderata. The paper then applies this concept in both humans and non-human animals. (shrink)

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)

Against the view that symbol-based semiosis is a human cognitive uniqueness, we have argued that non-human primates such as African vervet monkeys possess symbolic competence, as formally defined by Charles S. Peirce. Here I develop this argument by showing that the equivocal role ascribed to symbols by “folk semiotics” stems from an incomplete application of the Peircean logical framework for the classification of signs, which describes three kinds of symbols: rheme, dicent and argument. In an attempt to advance in the (...) classifying semiotic processes, Peirce proposed several typologies, with different degrees of refinement. Around 1903, he developed a division into ten classes. According to this typology, symbols can be further analysed in three subclasses (rheme, dicent, argument). I proceed to demonstrate that vervet monkeys employ dicent symbols. There are remarkable implications of this argument since ‘symbolic species theory’ fails to explore the vast Peircean semiotic philosophy to frame questions regarding the emergence and evolution of symbolic processes.

Robots seemingly in possession of an experiential mind, as well as humans allegedly incapable thereof, have been reported to elicit feelings of eeriness in their perceivers. The current work re-examined this claim, asking participants to rate both robots and humans in various social situations regarding their mind capacities, non-mind qualities, and overall appeal. It was found that feelings of eeriness towards both targets formed a distinct emotional response that was separable from simple dislike. Yet, unexpectedly, eeriness towards both targets intensified, (...) the less they were seen as possessing a typical human mind. For robots, however, this association was less consistent. Moreover, eeriness towards robots, but not towards humans, was most strongly predicted by a lack of perceived usefulness. These results indicate that mind attributions affect people’s attitudes towards each other more strongly than their attitudes towards humanoid robots. (shrink)

Confucianism has attracted some attention in business ethics, in particular as a form of virtue ethics. This paper develops ideas about Confucianism in business ethics by extending discussion about Confucian ideas of ritual. Ritual has figured in literature about organisational culture, but Confucian accounts can offer additional ideas about developing ethically desirable organisational cultures. Confucian ritual practice has diverged from doctrine and from the classical emphasis on requirements for concern and respect as parts of ritual. Despite some differences of emphasis (...) amongst early writers, classical texts like the Analects and Mencius allow for the importance of ritual as opportunity for interpersonal encounter. These are texts that bring out the flexibility and context-sensitivity of ritual, with associated implications about the need for care and attention to other individuals. They eschew ritual as unthinking repetition, in favour of ritual as meaningful expression. The mutual awareness such ritual can engender is an important part of human existence. Such ritual is a means to solving coordination problems through common knowledge, as opposed to unthinking routine. Undue routinisation can be one problem with organisational ritual, while another can be use of ritual as a means of oppressive control. In organisations, ritual should satisfy general requirements of concern and respect, and should maintain opportunities for mutual encounter. The difference between arrangements which do or do not offer such opportunities may suggest lines of development for virtue ethics in business. (shrink)

Many digital technologies, designed and controlled by intensive data-driven corporate platforms, have become ubiquitous for many of our daily activities. This has raised political and ethical concerns over how they might be threatening our personal autonomy. However, not much philosophical attention has been paid to the specific role that their hyper-designed (sensorimotor) interfaces play in this regard. In this paper, we aim to offer a novel framework that can ground personal autonomy on sensorimotor interaction and, from there, directly address how (...) technological design affects personal autonomy. To do this, we will draw from enactive sensorimotor approaches to cognition, focusing on the central notion of habits, understood as sensorimotor schemes that, in networked relations, give rise to sensorimotor agency. Starting from sensorimotor agency as a basis for more complex forms of personal autonomy, our approach gives us grounds to analyse our relationship with technology (in general) and to distinguish between autonomy-enhancing and autonomy-diminishing technologies. We argue that, by favouring/obstructing the enactment of certain (networks of) habits over others, technologies can directly act upon our personal autonomy, locally and globally. With this in mind, we then discuss how current digital technologies are often being designed to be autonomy-diminishing (as is the case of “dark patterns” in design), and sketch some ideas on how to build more autonomy-enhancing digital technologies.

Philosophical views of language have traditionally been focused on notions of truth. This is a reconstructive view in that we try to extract from an utterance in context what the sentence and speaker meaning are. This focus on meaning extraction from word sequences alone, however, is challenged by utterances which combine different types of figures. This paper argues that what appears to be a special case of ironic utterances—ironic metaphorical compounds—sheds light on the requirements for psychological plausibility of a theory (...) of communication and thus presents a different view of communication and language to that dominant in philosophy of language. In the view presented here, the hearer does not extract the speaker’s communicative intention from the sequence of words in the utterance, but from other channels, so as to constrain the inferential space for the sentence and speaker meaning. Specifically, we examine an example of ironic metaphor discussed by Stern. He argues that ironic content is logically dependent on metaphorical content, but makes no claims about how psychologically plausible this is in terms of the processing order. We argue that a straightforward translation of logical order into temporal order makes little sense. The primary sticking point is that without a prior understanding of the speaker’s communicative intentions, it is computationally more challenging to process the sub-component meanings. An alternative solution based on communicative channels leads us to a more psychologically plausible account of the structure of communicative acts and intentions. This provides support for the psychological realism of a richer theory of communicative intent. (shrink)

Research has shown that observers automatically align their attention with another’s gaze direction. The present study investigates whether inferring another’s attended location affects the observer’s attention in the same way as observing their gaze direction. In two experiments, we used a laterally oriented virtual human head to prime one of two laterally presented targets. Experiment 1 showed that, in contrast to the agent with closed eyes, observing the agent with open eyes facilitated the observer’s alignment of attention with the primed (...) target location. Experiment 2, where either sunglasses or occluders concealed the agent’s eye direction, showed that only the agent with the sunglasses facilitated the observer’s alignment of attention with the target location. Taken together, the data demonstrate that head orientation alone is not sufficient to trigger a shift in the observer’s attention, that gaze direction is crucial to this process, and that inferring the region to which another person is attending does facilitate the alignment of attention.

Two of the main theoretical approaches to the evolution of language are biolinguistics and usage-based approaches. Both are often conceptualized as belonging to seemingly irreconcilable ‘camps.’ Biolinguistic approaches assume that the ability to acquire language is based on a language-specific genetic foundation. Usage-based approaches, on the other hand, stress the importance of domain-general cognitive capacities, social cognition, and interaction. However, there have been a number of recent developments in both paradigms which suggest that biolinguistic and usage-based approaches are actually moving (...) closing together. For example, theoretical advancements such as evo-devo and complex adaptive systems theory have gained traction in the language sciences, leading to changed conceptions of issues like the relative influence of “nature” and “nurture.” In this paper, we outline points of convergence between current minimalist biolinguistic and usage-based approaches regarding four contentious issues: a) modularity and domain-specificity, b) innateness and development, c) cultural and biological evolution, d) knowledge of language and its description. We show that across both paradigms, researchers have come to increasingly embrace more complex views of these issues. They also have come to appreciate the view that biological and cultural evolution are closely intertwined, which leads to an increased amount of common ground between minimalist biolinguistics and usage-based approaches.

In recent years, multiple researchers working on the evolution of language have put forward the idea that the theoretical framework of usage-based approaches and Construction Grammar is highly suitable for modelling the emergence of human language from pre-linguistic or proto-linguistic communication systems. This also raises the question of whether usage-based and constructionist approaches can be integrated with the analysis of animal communication systems. In this paper, we review possible avenues where usage-based, constructionist approaches can make contact with animal communication research, (...) which in turn also has implications for theories of language evolution. To this end, we first give an overview of key assumptions of usage-based and constructionist approaches before reviewing some key issues in animal communication research through the lens of usage-based, constructionist approaches. Specifically, we will discuss how research on alarm calls, gestural communication and symbol-trained animals can be brought into contact with usage-based, constructionist theorizing. We argue that a constructionist view of animal communication can yield new perspectives on its relation to human language, which in turn has important implications regarding the evolution of language. Importantly, this theoretical approach also generates hypotheses that have the potential of complementing and extending results from the more formalist approaches that often underlie current animal communication research.

According to one currently influential line of thinking, the evolution of ostensive communication was a prerequisite for the evolution of human language. In this article, I distinguish between a strong and a weak version of this view and offer a sustained argument against the former. More specifically, the strong version of this view would have it that ostensive communication was a prerequisite not just for the evolution of fully modern language but for any language-like system of communication. I argue that (...) this version is too strong: I show how some distinctive and important features of language may well have been assembled prior to the evolution of ostensive communication. Put another way, I argue that a protolanguage before ostensive communication scenario is a real possibility. I conclude by briefly arguing that such an evolutionary scenario coheres better with archaeological evidence from the early Pleistocene as well as evidence from developmental psychology pertaining to the nature of our mind reading abilities.

La atención conjunta se da cuando dos sujetos atienden al mismo objeto a la vez, y el hecho es cognitivamente abierto. Existen dos enfoques al respecto: el primero reconoce que cada sujeto sabe que el otro está percibiendo lo mismo, es decir, es un co-perceptor; se trata, entonces, de explicar en qué consiste ser un co-perceptor. El segundo enfoque resalta que los sujetos saben que el objeto está siendo percibido por ambos; en dicho caso, se trata de explicar en qué (...) consiste que un objeto sea percibido como perceptualmente compartido. En este texto se analizan las razones del primer enfoque para mostrar por qué es desorientador; y se dan razones para validar el segundo enfoque.

Our target article proposed that language production and comprehension are interwoven, with speakers making predictions of their own utterances and comprehenders making predictions of other people's utterances at different linguistic levels. Here, we respond to comments about such issues as cognitive architecture and its neural basis, learning and development, monitoring, the nature of forward models, communicative intentions, and dialogue.

Currently, production and comprehension are regarded as quite distinct in accounts of language processing. In rejecting this dichotomy, we instead assert that producing and understanding are interwoven, and that this interweaving is what enables people to predict themselves and each other. We start by noting that production and comprehension are forms of action and action perception. We then consider the evidence for interweaving in action, action perception, and joint action, and explain such evidence in terms of prediction. Specifically, we assume (...) that actors construct forward models of their actions before they execute those actions, and that perceivers of others' actions covertly imitate those actions, then construct forward models of those actions. We use these accounts of action, action perception, and joint action to develop accounts of production, comprehension, and interactive language. Importantly, they incorporate well-defined levels of linguistic representation. We show how speakers and comprehenders use covert imitation and forward modeling to make predictions at these levels of representation, how they interweave production and comprehension processes, and how they use these predictions to monitor the upcoming utterances. We show how these accounts explain a range of behavioral and neuroscientific data on language processing and discuss some of the implications of our proposal. (shrink)

Pietraszewski provides a compelling case that representations of certain interaction-types are the “cognitive primitives” that allow all tokens of group-in-conflict to be represented within the mind. Here, I argue that the folk concept GROUP encodes shared intentions and goals as more central than these interaction-types, and that providing a computational theory of social groups will be more difficult than Pietraszewski envisages.

Why is interaction so simple? This article presents a theory of interaction based on the use of shared representations as “coordination tools” (e.g., roundabouts that facilitate coordination of drivers). By aligning their representations (intentionally or unintentionally), interacting agents help one another to solve interaction problems in that they remain predictable, and offer cues for action selection and goal monitoring. We illustrate how this strategy works in a joint task (building together a tower of bricks) and discuss its requirements from a (...) computational viewpoint. (shrink)

I argue that analyses of various kinds of cooperation will benefit from an account of the cognitive and communicative functions required for the cooperation. In particular, I focus on the role of intersubjectivity , which has not been sufficiently considered in game theory. Intersubjectivity will here be divided into representing the emotions, desires, attention, intentions, and beliefs of others. I then analyze some kinds of cooperation—reciprocal altruism, indirect reciprocity, cooperation on future goals, and conventions—with respect to their cognitive and communicative (...) prerequisites. It is argued that uniquely human forms of cooperation depend on advanced forms of intersubjectivity. (shrink)

In this paper I put forward a thesis regarding the anatomy of “cultural evolution”, in particular the way the “cultural” transmission of behavioral patterns came to piggyback, through us humans, on the transmission effected by genetic evolution. I claim that what grounds and supports this new kind of transmission is a complex behavioral “meta-pattern” that makes it possible to grasp a pattern as something that “ought to be”, i.e. that transforms the pattern into what we can call a rule. (Here (...) I draw especially on the philosophical insights of Wilfrid Sellars.) In this way I interlink empirical research done in evolution theory with some more speculative philosophical theories, thus shedding new light on the former and adding an empirical footing to the latter.

In virtue of their capacity for political agency, political agents can possess special rights, powers, and responsibilities, such as rights to political participation and freedom of speech. Traditionally, political theorists have assumed that only cognitively unimpaired adult humans are political agents, and thus that only those humans can be the bearers of these rights, powers, and responsibilities. However, recent work in animal rights theory has extended the concept of political agency to nonhuman animals. In this article, I develop an account (...) of political agency that identifies the capacities that one must possess to be a political agent and captures the fact that political action is a distinctive type of action. Crucially, this account makes sense of the standard assumption that only some humans count as political agents, and explains why few nonhuman animals, human infants, and severely cognitively impaired humans are likely to possess the capacity for political agency. I go on to reject the view, recently advanced by Sue Donaldson and Will Kymlicka, that nonhuman animals can be ‘nonintentional political agents’. I conclude by suggesting that most nonhuman animals, as well as human infants and humans with severe cognitive impairments, cannot straightforwardly be assigned rights to political participation.

Over the last quarter century, the dominant tendency in comparative cognitive psychology has been to emphasize the similarities between human and nonhuman minds and to downplay the differences as (Darwin 1871). In the present target article, we argue that Darwin was mistaken: the profound biological continuity between human and nonhuman animals masks an equally profound discontinuity between human and nonhuman minds. To wit, there is a significant discontinuity in the degree to which human and nonhuman animals are able to approximate (...) the higher-order, systematic, relational capabilities of a physical symbol system (PSS) (Newell 1980). We show that this symbolic-relational discontinuity pervades nearly every domain of cognition and runs much deeper than even the spectacular scaffolding provided by language or culture alone can explain. We propose a representational-level specification as to where human and nonhuman animals' abilities to approximate a PSS are similar and where they differ. We conclude by suggesting that recent symbolic-connectionist models of cognition shed new light on the mechanisms that underlie the gap between human and nonhuman minds. (shrink)

Scholars have long pointed to the power of music as a primary source in instruction for bringing past actors into sharper view and engender deeper connections with the past. By employing Dimitri Shostakovich's 7th Symphony, composed amidst the Nazi siege of Leningrad during the Second World War, we sought to explore, more precisely, the nature of how music, as a primary source, enhances the study of history among students. Through the formulation, execution, and assessment of a two-day lesson with students (...) in five secondary history classes, three of which listened to the symphony and two of which did not, we found that the incorporation of the symphony resulted in students’ enhanced empathetic understanding of the past. Implications include details regarding profound opportunities for, as well as challenges to, cultivating historical empathy through the use of music as a primary source. (shrink)

Michael Tomasello ( 2016 ) prominently defends the view that there are uniquely human capacities required for shared intentions, therefore great apes do not share intentions. I show that these uniquely human capacities for abstraction are not necessary for shared intentionality. Excluding great apes from shared intentions because they lack certain capacities for abstraction assumes a specific interpretation of shared intentionality, which I call the Roleplaying Model. I undermine the necessity of abstraction for shared intentionality by presenting an alternative model (...) of shared intentionality, which I call the Normative Model. It is a modification of Margaret Gilbert’s ( 2013 ) Plural Subject theory, which I modify such that it is, in principle, compatible with nonhuman shared intentionality. To do this, I substitute Gilbert’s account of obligation for Kristin Andrews’ ( 2020 ) account of animal social norms. In this Normative Model, uniquely human capacities for abstraction are not required for shared intentionality. By undermining the necessity of uniquely human abstraction, I make cases of prima-facie cooperation in chimpanzees plausible instances of shared intentionality. The Roleplaying Model’s denial of nonhuman shared intentionality creates a problem insofar as apparent shared intentional activity cannot be fully analyzed. The Normative Model resolves this problem.
