The "theory of mind" framework has been the fastest growing body of empirical research in contemporary psychology. It has given rise to a range of positions on what it takes to relate to others as intentional beings. This book brings together disparate strands of ToM research, lays out historical roots of the idea, and indicates better alternatives.

A major challenge for research in artificial intelligence is to develop systems that can infer the goals, beliefs, and intentions of others (i.e., systems that have theory of mind, ToM). In this research, we propose a cognitive ToM framework that uses a well-known theory of decisions from experience to construct a computational representation of ToM. Instance-based learning theory (IBLT) is used to construct a cognitive model that generates ToM from the observation of other agents' behavior. The (...) IBL model of the observer distinguishes itself from previous models of ToM that make unreasonable assumptions about human cognition, are hand-crafted for particular settings, complex, or unable to explain a cognitive development of ToM compared to human's ToM. The IBL model learns from the observation of goal-directed agents' behavior in a gridworld navigation task, and it infers and predicts the behaviors of the agents in new gridworlds across different degrees of decision complexity in similar ways to the way human observers do. We provide evidence for the alignment of the IBL observer's predictions under various levels of decision complexity. We also advance the demonstration of the IBL predictions using a classic test of false beliefs (the Sally–Anne test), which is commonly used to test ToM in humans. We discuss our results and the potential of the IBL observer model to improve human–machine interactions. (shrink)

Whether any non-human animal can attribute mental states to others remains the subject of extensive debate. This despite the fact that several species have behaved as if they have a ‘theory of mind’ in various behavioral tasks. In this paper, we review the reasons of skeptics for their doubts: That existing experimental setups cannot distinguish between ‘mind readers’ and ‘behavior readers’, that results that seem to indicate ‘theory of mind’ may come from studies that are (...) insufficiently controlled, and that our own intuitive biases may lead us to interpret behavior more ‘cognitively’ than is necessary. The merits of each claim and suggested solution are weighed. The conclusion is that while it is true that existing setups cannot conclusively demonstrate ‘theory of mind’ in non-human animals, focusing on this fact is unlikely to be productive. Instead, the more interesting question is how sophisticated their social reasoning can be, whether it is about ‘unobservable inner experiences’ or not. Therefore, it is important to address concerns about the setup and interpretation of specific experiments. To alleviate the impact of intuitive biases, various strategies have been proposed in the literature. These include a deeper understanding of associative learning, a better knowledge of the limited ‘theory of mind’ humans actually use, and thinking of animal cognition in an embodied, embedded way; that is, being aware that constraints outside of the brain, and outside of the body, may naturally predispose individuals to produce behavior that looks smart without requiring complex cognition. To enable this kind of thinking, a powerful methodological tool is advocated: Computational modeling, namely agent-based modeling and, particularly, cognitive modeling. By explicitly simulating the rules and representations that underlie animal performance on specific tasks, it becomes much easier to look past one’s own biases and to see what cognitive processes might actually be occurring.

Theory of mind” consists in the ability to use concepts of intentional mental states, such as beliefs, emotions, intentions, goals, and perceptual states, in order to predict and interpret behavior. Functional magnetic resonance imaging studies have revealed a distinctive network of neural regions that is active during theory-of-mind tasks, including the temporal-parietal junction, the posterior superior temporal sulcus, the medial prefrontal cortex, the precuneus, and the temporal poles (Van Overwalle 2009). Deficits in theory-of-mind abilities, (...) which are common in autism spectrum disorder (Tager-Flusberg 2007), typically correlate with broader difficulties in social understanding. -/- Many scholars have suggested that theory of mind is an innate adaptation for social cognition, emerging very early in development and playing a crucial role in social learning and the acquisition of language (Baron-Cohen 1997). However, others have argued that theory of mind is the product of largely domain-general learning processes and is acquired gradually over the course development through social experience (Wellman 2014). A third view argues that humans possess two systems for theory of mind: an innate, domain-specific “implicit” system and a learned, domain-general “explicit” system (Apperly and Butterfill 2009).

Research on theory of mind has primarily focused on demonstrating and understanding the ability to represent others' non‐factive mental states, for example, others' beliefs in the false‐belief task. This requirement confuses the ability to represent a particular kind of non‐factive content (e.g., a false belief) with the more general capacity to represent others' understanding of the world even when it differs from one's own. We provide a way of correcting this. We first offer a simple and theoretically motivated (...) account on which tracking another agent's understanding of the world and keeping that representation separate from one's own are the essential features of a capacity for theory of mind. We then show how these criteria can be operationalized in a new experimental paradigm: the “diverse‐knowledge task.”. (shrink)

ABSTRACTThe recognition of emotional facial expressions is often subject to contextual influence, particularly when the face and the context convey similar emotions. We investigated whether spontaneous, incidental affective theory of mind inferences made while reading vignettes describing social situations would produce context effects on the identification of same-valenced emotions as well as differently-valenced emotions conveyed by subsequently presented faces. Crucially, we found an effect of context on reaction times in both experiments while, in line with previous work, we (...) found evidence for a context effect on accuracy only in Experiment 1. This demonstrates that affective theory of mind inferences made at the pragmatic level of a text can automatically, contextually influence the perceptual processing of emotional facial expressions in a separate task even when those emotions are of a distinctive valence. Thus, our novel findings suggest that language acts as a contex... (shrink)

Both mindreading and stereotyping are forms of social cognition that play a pervasive role in our everyday lives, yet too little attention has been paid to the question of how these two processes are related. This paper offers a theory of the influence of stereotyping on mental-state attribution that draws on hierarchical predictive coding accounts of action prediction. It is argued that the key to understanding the relation between stereotyping and mindreading lies in the fact that stereotypes centrally involve (...) character-trait attributions, which play a systematic role in the action–prediction hierarchy. On this view, when we apply a stereotype to an individual, we rapidly attribute to her a cluster of generic character traits on the basis of her perceived social group membership. These traits are then used to make inferences about that individual’s likely beliefs and desires, which in turn inform inferences about her behavior. (shrink)

Theory of Mind (ToM) or mentalization is the ability to understand and foresee the behavior referring to one's own and others' mental states (Premack & Woodruff, 1978; Wimmer & Perner, 1983). This capacity, which is considered the most representative mechanism of social cognition, is a multifaceted set of competences liable to influence--and be influenced by--a manifold of psychosocial aspects. Studies on typical and atypical/clinical development during life showed that ToM is frequently delayed (e.g. in deafness) or impaired in (...) many clinical conditions (e.g. Autism Spectrum Disorder, Attention Deficit Hyperactivity Disorder, Schizophrenia, Borderline Personality Disorder, Parkinson's Disease, Alzheimer's Disease) and, on the other hand, may not be unequivocally a positive experience. It is therefore possible to consider the existence of multiple kinds of Theory of Mind. In fact, ToM may vary along a quantitative and a qualitative continuum. As for the quantitative dimension, the continuum is constituted by the fluctuation between high and low levels of ToM ability in different clinical conditions. Along this continuum, impairment can mean "not enough" ToM (for example in Autism Spectrum Disorder) as well as "too much" ToM (for example in Schizophrenia and Borderline Personality Disorder). The qualitative dimension--highly interrelated with the quantitative one--regards the shift between adaptive (e.g. prosocial, nice ToM) vs. unadaptive (e.g. antisocial, nasty ToM) mental states content. The issue is discussed in light of recent evidence from outstanding researchers working on typical and atypical/clinical populations along the life-span. Findings from the fields of psychology, neuropsychology and neuroscience enrich the research topic argumentation"--Page 2. (shrink)

Henry Wellman and colleagues have provided evidence of a robust developmental progression in theory-of-mind (or as we will say, “mindreading”) abilities, using verbal tasks. Understanding diverse desires is said to be easier than understanding diverse beliefs, which is easier than understanding that lack of perceptual access issues in ignorance, which is easier than understanding false belief, which is easier than understanding that people can hide their true emotions. These findings present a challenge to nativists about mindreading, and are (...) said to support a social-constructivist account of mindreading development instead. This article takes up the challenge on behalf of nativism. Our goal is to show that the mindreading-scale findings fail to support constructivism because well-motivated alternative hypotheses have not yet been controlled for and ruled out. These have to do with the pragmatic demands of verbal tasks. (shrink)

Whereas Phillips and colleagues argue that knowledge representations are more basic than belief representations, we argue that an accurate analysis of what is fundamental to theory of mind may depend crucially on the context in which mental-state reasoning occurs. Specifically, we call for increased study of the developmental trajectory of mental-state reasoning within socially evaluative contexts.

Publisher Summary This chapter describes the different aspects of the theory of mind and autism. Difficulty in understanding other minds is a core cognitive feature of autism spectrum conditions. It is found that normal 3- to 4-year-olds already know that the brain has a set of mental functions, such as dreaming, wanting, thinking, and keeping secrets. In contrast, children with autism appear to know about the physical functions, but typically fail to mention any mental function of the brain. (...) Children with autism, when studied under experimental conditions, have been shown to have difficulties both in the production of deception and in understanding when someone else is deceiving them. People with autism-spectrum conditions are clearly having mentalizing difficulties for reasons different from those seen in people with learning difficulties or those who are blind or deaf, since a deficit can be revealed even in the highest functioning individuals with an autism-spectrum condition in whom general comprehension problems can be ruled out.

Armstrong's Materialist Theory of Mind is one of a handful of texts that began the physicalist revolution in the philosophy of mind. In this collection, distinguished philosophers examine what we still owe to it, how to expand it, as well as looking back on how it came about.

The neuropsychological and functional characterisation of mental state attribution (‘‘theory of mind’’ (ToM)) has been the focus of several recent studies. The literature contains opposing views on the functional specificity of ToM and on the neuroanatomical structures most relevant to ToM. Studies with brain-lesioned patients have consistently found ToM deficits associated with unilateral right hemisphere damage (RHD). Also, functional imaging performed with non-braininjured adults implicates several specific neural regions, many of which are located in the right hemisphere. The (...) present study examined the separation of ToM impairment from other deficits associated with brain injury. We tested 11 patients with unilateral right hemisphere damage (RHD) and 20 normal controls (NC) on a.. (shrink)

We tested if the newly designed ToMotion task reflects a single construct and if the atypical groups differ in their performance compared to typically developing peers. Furthermore, we were interested if ToMotion maps a developmental sequence in a Theory of Mind performance as exemplified by increasing difficulty of the questions asked in every item. The sample consisted of 13 adolescents that have been diagnosed with a developmental language disorder and 14 adolescents that are deaf or hard of hearing. (...) All of these adolescents were in special schools for secondary vocational education. The control group existed of 34 typical developing adolescents who were in regular intermediate vocational education, ranging from level 2 to 4. The ToMotion, available in a spoken Dutch version and in a version in Sign Language of the Netherlands, was used to map ToM abilities. An attempt has been made to fill the gap of missing studies of ToM in adolescents by developing a new measuring instrument. In conclusion, assessing ToM with the ToMotion results in a picture that DHH adolescents score lower than TD peers. However, their scores are as consistent as those of the TD peers. The picture of DLD adolescents is the reverse. They show no differences in ToM scores, but seem to be somewhat more inconsistent compared to TD peers. We provide a discussion on those results and its implications for future research. What this paper adds? The current study introduces a new visual Theory of Mind task, ToMotion, designed specifically to assess ToM in adolescents in an ecologically valid way and adapted to the needs of adolescents with language and communication difficulties.

Whether to treat autism as exculpatory in any given circumstance appears to be influenced both by models of autism and by theories of moral responsibility. This article looks at one particular combination of theories: autism as theory of mind challenges and moral responsibility as requiring appropriate experience of the reactive attitudes. In pursuing this particular combination of ideas, we do not intend to endorse them. Our goal is, instead, to explore the implications of this combination of especially prominent (...) ideas about autism and about moral responsibility. These implications can be quite serious and practical for autists and those who interact directly with autists, as well as for broader communities as they attend to the fair, compassionate, and respectful treatment of increasing numbers of autistic adults. We find that these theories point to a limited range of situations in which autists should not be blamed for transgressive actions for which neurotypical individuals should be blamed. We build on what others have written on these issues by bringing in a recent cognitive model of the role theory of mind plays in empathy, by discussing the social implications of the theoretical findings, and by raising questions about the compatibility of reactive attitude theories of moral responsibility with the neurodiversity approach to autism.

Descartes is possibly the most famous of all writers on the mind, but his theory of mind has been almost universally misunderstood, because his philosophy has not been seen in the context of his scientific work.

For Clarke, the key is to interpret his philosophical efforts as an attempt to reconcile his scientific pursuits with the (...) theologically orthodox views of his time. (shrink)

This paper explores the idea that when dealing with certain kinds of narratives, ‘like it or not’, consumers of fiction will bring the same sorts of skills (or at least a subset of them) to bear that they use when dealing with actual minds. Let us call this the ‘Same Resources Thesis’. I believe the ‘Same Resources Thesis’ is true. But this is because I defend the view that engaging in narrative practices is the normal developmental route through which children (...) acquire the capacity to make sense of what it is to act for a reason. If so, narratives are what provide crucial resources for dealing with actual minds – at least those of a certain sophisticated sort. I argue however that to the extent that we mindread at all, it is likely that we – i.e. those with the appropriate linguistically scaffolded abilities to make mental attributions – rely on our basic mind minding capacities to do so. So theory only comes into play when we mind guess, but theory of mind doesn’t come into it at all, neither when we deal with actual or fictional minds. (shrink)

Intuitively, even very young children can act jointly. For instance, a child and her parent can build a simple tower together. According to developmental psychologists, young children develop theory of mind by, among other things, participating in joint actions like this. Yet many leading philosophical accounts of joint action presuppose that participants have a robust theory of mind. In this article, I examine two philosophical accounts of joint action designed to circumvent this presupposition, and then I (...) proffer my own novel account of what makes (at least some) interactions between very young children and others joint. I argue that children can take up without deliberation intentions with a joint content that have been transmitted to them by others. In doing so, children can come to share intentions with others, and by acting on these shared intentions they can come to act jointly, all without employing a robust theory of mind. (shrink)

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

Theory of mind refers to the human capacity for reasoning about others’ mental states based on observations of their actions and unfolding events. This type of reasoning is notorious in the cognitive science literature for its presumed computational intractability. A possible reason could be that it may involve higher-order thinking. To investigate this we formalize theory of mind reasoning as updating of beliefs about beliefs using dynamic epistemic logic, as this formalism allows to parameterize ‘order of (...) thinking.’ We prove that theory of mind reasoning, so formalized, indeed is intractable. Using parameterized complexity we prove, however, that the ‘order parameter’ is not a source of intractability. We furthermore consider a set of alternative parameters and investigate which of them are sources of intractability. We discuss the implications of these results for the understanding of theory of mind. (shrink)

The case for computationalism about the mind is in doubt when we acknowledge that there are mental phenomena that require, for a proper accounting, that we get below the level of symbol processing. Such phenomena show us that a computational theory of mind cannot be complete. Chief among these phenomena is emotion.

The theory of mind (ToM) deficit associated with autism spectrum disorder has been a central topic in the debate about the modularity of the mind. In a series of papers, Philip Gerrans and Valerie Stone argue that positing a ToM module does not best explain the deficits exhibited by individuals with autism (Gerrans 2002; Stone & Gerrans 2006a, 2006b; Gerrans & Stone 2008). In this paper, I first criticize Gerrans and Stone’s (2008) account. Second, I discuss various (...) studies of individuals with autism and argue that they are best explained by positing a higher-level, domain-specific ToM module. (shrink)

Theory of Mind (ToM) is one of the most relevant concepts in the field of social cognition, particularly in the case of Autism Spectrum Disorders (ASD). Literature showing that individuals with ASD display deficits in ToM is extensive and robust. However, some related issues deserve more research: the heterogeneous profile of ToM abilities in children with ASD and the association between different levels of ToM development and social, pragmatic, and adaptive behaviors in everyday life. The first objective of (...) this study was to identify profiles of children with ASD without intellectual disability (ID), based on explicit and applied ToM knowledge, and compare these profiles with a group of children with typical development (TD). A second objective was to determine differences in symptom severity, adaptive/social behavior, and pragmatic abilities between the profiles identified. Fifty-two children with a clinical diagnosis of ASD without ID and 37 children with TD performed neuropsychological ToM tasks and two vocabulary and memory tests. In addition, all of their mothers completed different questionnaires about applied ToM abilities, severity of ASD symptoms, adaptive/social skills, and pragmatic competence. Two subgroups were identified in the cluster analysis carried out with explicit and applied ToM indicators. The “Lower ToM abilities” profile obtained significantly lower scores than the “Higher ToM abilities” profile on all the ToM measures. Furthermore, the analysis of covariance, controlling for vocabulary and working memory (ANCOVAs), showed statistically significant differences in applied ToM abilities between the two groups of children with ASD without ID and the group with TD. However, only the group with “Higher ToM abilities” achieved similar performance to the TD group on the verbal task of explicit ToM knowledge. Finally, the “Lower ToM abilities” cluster obtained significantly higher scores on autism symptoms (social and communication domains) and lower scores on adaptive behavior and pragmatic skills than the cluster with “Higher ToM abilities”. Taken together, these findings have implications for understanding the heterogeneity in ToM skills in children with ASD without ID, and their differential impact on social, communicative, and adaptive behaviors.

Aron Gurwitsch’s Gestalt-inspired “field theory of consciousness” was introduced in the same period as Wolfgang Köhler’s theory of “electrical brain fields.” I consider parallels between these theories, drawing on results that have emerged in the last five years. First, I consider the claim that fields of consciousness supervene on electromagnetic fields in the brain, then I outline Gurwitsch’s field theory of consciousness, and finally I consider how the structures described by Gurwitsch might relate to structures in the (...) brain’s electro-magnetic field. Along the way, I expose a dogma (that qualia are paradigmatic conscious states) and develop an interpretation of Gurwitsch’s field theory. (shrink)

In everyday life it is often important to have a mental model of the knowledge, beliefs, desires, and intentions of other people. Sometimes it is even useful to to have a correct model of their model of our own mental states: a second-order Theory of Mind. In order to investigate to what extent adults use and acquire complex skills and strategies in the domains of Theory of Mind and the related skill of natural language use, we (...) conducted an experiment. It was based on a strategic game of imperfect information, in which it was beneficial for participants to have a good mental model of their opponent, and more specifically, to use second-order Theory of Mind. It was also beneficial for them to be aware of pragmatic inferences and of the possibility to choose between logical and pragmatic language use. We found that most participants did not seem to acquire these complex skills during the experiment when being exposed to the game for a number of different trials. Nevertheless, some participants did make use of advanced cognitive skills such as second-order Theory of Mind and appropriate choices between logical and pragmatic language use from the beginning. Thus, the results differ markedly from previous research. (shrink)

There is a thesis often aired by some philosophers of psychology that syntax is all we need and there is no need to advert to intentional/semantic properties of symbols for purposes of psychological explanation. Indeed, the worry has been present since the first explicit articulation of so-called Computational Theory of Mind (CTM). Even Fodor, who has been the most ardent defender of the Language of Thought Hypoth- esis (LOTH) (which requires the CTM), has raised worries about its apparent (...) consequences.

Representational theories of mind cannot individuate the sense modalities in a principled manner. According to representationalism, the phenomenal character of experiences is determined by their contents. The usual objection is that inverted qualia are possible, so the phenomenal character of experiences may vary independently of their contents. But the objection is inconclusive. It raises difficult questions about the metaphysics of secondary qualities and it is difficult to see whether or not inverted qualia are possible. This paper proposes an alternative (...) test of representationalism. Do experiences in different sense modalities have the same phenomenal character when they share content? Psychological work on the perception of shape through vision and spatial hearing is discussed. This work shows that visual and auditory experiences differ in phenomenal character even in so far as they represent similar properties. This objection to representationalism does not invite questions about secondary qualities or depend on establishing metaphysical possibilities. (shrink)

The ability to understand other minds is key to communication, social organization, and culture, and actively researched in disciplines such as psychology, ethology, and primatology. The German philosopher Edmund Husserl (1859-1938) developed an elaborate theory of how we understand others, then commonly referred to as empathy (Theorie der Einfühlung). Much recent work on Husserl's theory has interpreted him in opposition to Theory of Mind (ToM), but Husserl's layered account of empathy has received little attention, and so (...) have the more recent versions of ToM, which work with orders of intentionality, and which are applied widely in social cognition research today. This article focuses on Husserl's layered approach, highlighting the main takeaways of his theory, while also providing a commentary, which reflects on his work from a contemporary perspective. This yields a rather different interpretation of him, one which reveals hitherto unnoticed connections with diverse areas of social cognition scholarship. (shrink)

Conversational and neurological explanations for deficits in mental state understanding are considered in relation to recent evidence from studies of deaf, (...) autistic, and normally developing children with varied levels of access to talk about mental states at home with family members during the preschool years.

Do children have a theory of mind? If they do, at what age is it acquired? What is the content of the theory, and how does it differ from that of adults? The Child's Theory of Mind integrates the diverse strands of this rapidly expanding field of study. It charts children's knowledge about a fundamental topic - the mind - and characterizes that developing knowledge as a coherent commonsense theory, strongly advancing the understanding (...) of everyday theories as well as the commonsense theory of mind. Wellman presents evidence that children as young as age three do possess a commonsense theory of mind - that they grasp the distinction between mental constructs and physical entities and that they have an understanding of the relationship between individuals' mental states and their overt actions. He delves in detail into questions about the nature of adults' commonsense theories of mind and about the nature of commonsense theories. Wellman then examines the content of the three-year-old's theory of mind, the nature of children's notions of mind before age three, the changes in the theory during subsequent development from ages three to six, and the young child's conception of mind in comparison with those of older children and adults.

There is growing acceptance among language evolution researchers that an increase in our ancestors’ theory of mind capacities was critical to the origins of language. However, little attention has been paid to the question of how those capacities were in fact upgraded. This article develops a novel hypothesis, grounded in contemporary cognitive neuroscience, on which our theory of mind capacities improved as a result of an increase in our System-2 thinking capacities, in turn based in an (...) increase in our working memory capacities. I contrast this hypothesis with what would appear to be the default position among language evolution researchers, namely, that our theory of mind became more powerful as a result of genetic change to a domain-specific mindreading system which we share with other great apes. While the latter hypothesis is not implausible, it arguably enjoys less empirical support at present than does the alternative hypothesis I develop. (shrink)

The ascription of desires or beliefs to other people is a milestone of human sociality. It allows us to understand, explain, and predict human behaviour. During the last years, research on children's knowledge about the mental world, better known as theory of mind research, has become a central topic in developmental psychology and the role of cultural impact is subject of various theoretical yet hitherto few empirical accounts. This book is the result of intensive collaboration between anthropologists and (...) psychologists in the field of cross-cultural research on social cognitive development. Five interdisciplinary research teams, coming from the University of Heidelberg, were investigating five Pacific Island societies. All together, they were interested in the question of how and when children in these different cultures come to assign mental states to others. This unique research project combines sound ethnography of different Pacific cultures with thoroughly conducted experimental work, done by developmental psychologists; it presents a shared, thoughtful analysis of the results and provides deeper insight into current debates on the ontogeny of theory of mind competencies.
