The Theory Theory

Modularity theorists have challenged that there are, or could be, general learning mechanisms that explain theory-of-mind development. In response, supporters of the ‘scientific theory-theory’ account of theory-of-mind development have appealed to children's use of auxiliary hypotheses and probabilistic causal modeling. This article argues that these general learning mechanisms are not sufficient to meet the modularist's challenge. The article then explores an alternative domain-general learning mechanism by proposing that children grasp the concept belief through the progressive alignment of relational structure that (...) occurs as a result of structural-comparison. The article also explores the implications of the proposed account for Fodor's puzzle of conceptual learning. (shrink)

Alison Gopnik and Andrew Meltzoff have argued for a view they call the ‘theory theory’: theory change in science and children are similar. While their version of the theory theory has been criticized for depending on a number of disputed claims, we argue that there is a fundamental problem which is much more basic: the theory theory is multiply ambiguous. We show that it might be claiming that a similarity holds between theory change in children and (i) individual scientists, (ii) (...) a rational reconstruction of a Superscientist, or (iii) the scientific community. We argue that (i) is false, (ii) is non-empirical (which is problematic since the theory theory is supposed to be a bold empirical hypothesis), and (iii) is either false or doesn’t make enough sense to have a truth-value. We conclude that the theory theory is an interesting failure. Its failure points the way to a full, empirical picture of scientific development, one that marries a concern with the social dynamics of science to a psychological theory of scientific cognition.  2002 Elsevier Science Ltd.

Words, Thoughts and Theories arguesthat infants and children discover the physical and psychological featuresof the world by a process akin to scientific inquiry, more or less asconceived by philosophers of science in the 1960s (the theory theory).This essay discusses some of the philosophical background to analternative, more popular, ``modular'''' or ``maturational'''' account ofdevelopment, dismisses an array of philosophical objections to the theorytheory, suggests that the theory theory offers an undeveloped project forartificial intelligence, and, relying on recent psychological work oncausation, offers (...) suggestions about how principles of causal inference mayprovide a developmental solution to the ``frame problem''''.

Alison Gopnik and her collaborators have recently proposed a bold and intriguing hypothesis about the relationship between scientific cognition and cognitive development in childhood. According to this view, the processes underlying cognitive development in infants and children and the processes underlying scientific cognition are _identical_. We argue that Gopnik’s bold hypothesis is untenable because it, along with much of cognitive science, neglects the many important ways in which human minds are designed to operate within a social environment. This leads to (...) a neglect of _norms_ and the processes of _social_ _transmission_ which have an important effect on scientific cognition and cognition more generally. (shrink)

In this article we take issue with theory theory and simulation theory accounts of folk psychology committed to (i) the belief-desire (BD) model and (ii) the assumption of universality (AU). Recent studies cast doubt on the compatibility of these commitments because they reveal considerable cross-cultural differences in folk psychologies. We present both theory theory and simulation theory with the following dilemma: either (i) keep the BD-model as an account of the surface properties of specific explicit folk psychologies and give up (...) AU in light of the cross-cultural evidence; or (ii) defend AU with respect to core capacities underlying different culture-specific folk psychologies, and explain why the BD-model will be genuinely explanatory at this level.

Many philosophers and cognitive scientists claim that our everyday or "folk" understanding of mental states constitutes a theory of mind. That theory is widely called "folk psychology" (sometimes "commonsense" psychology). The terms in which folk psychology is couched are the familiar ones of "belief" and "desire", "hunger", "pain" and so forth. According to many theorists, folk psychology plays a central role in our capacity to predict and explain the behavior of ourselves and others. However, the nature and status of folk (...) psychology remains controversial. (shrink)

People are minded creatures; we have thoughts, feelings and emotions. More intriguingly, we grasp our own mental states, and conduct the business of ascribing them to ourselves and others without instruction in formal psychology. How do we do this? And what are the dimensions of our grasp of the mental realm? In this book, Alvin I. Goldman explores these questions with the tools of philosophy, developmental psychology, social psychology and cognitive neuroscience. He refines an approach called simulation theory, which starts (...) from the familiar idea that we understand others by putting ourselves in their mental shoes. Can this intuitive idea be rendered precise in a philosophically respectable manner, without allowing simulation to collapse into theorizing? Given a suitable definition, do empirical results support the notion that minds literally create surrogates of other peoples mental states in the process of mindreading? Goldman amasses a surprising array of evidence from psychology and neuroscience that supports this hypothesis. (shrink)

We contribute to the empirical debate on whether we understand and predict mental states by using simulation (simulation theory) or by relying on a folk psychological theory (theory theory). To decide between these two fundamental positions, it has been argued that failure to predict other people's choices would be challenging evidence against the simulation view. We test the specific claim that people prefer the rightmost position in choosing among equally valued objects, and whether or not this position bias can be (...) correctly predicted. A series of experiments shows that the bias appears only in a specific spatial arrangement and that it can be correctly predicted given adequate imaginative input. In concert with other recent findings on the correct prediction of choices these findings do actually strengthen, rather than challenge, the simulation account on the prediction of mental states.

Introspection is often seen as criterion to distinguish between theory theory (TT) and simulation theory (ST). Many empirical arguments against ST rely upon the thesis that ST is introspectionist and that it presupposes the Cartesian dictum that the mind is transparent to itself. According to Perner 1999 the capacity to introspect is so important for ST that it can be seen as the criterion that distinguishes ST from TT: "These two positions and their sub-varieties differ as to whether they presuppose (...) or explain the ability to introspect. Theory theory is extremely anti-introspectionist. Traditional simulation is based on the ability to introspect one's own mental states." (Perner 1999). (shrink)

We introduce a particular way of drawing the distinction between the use of theory and simulation in the prediction of people's decisions and describe an empirical method to test whether theory or simulation is used in a particular case. We demonstrate this method with two effects of decision making involving the choice between a safe option (take amount X) and a risky option (take double the amount X with probability 1/2). People's predictions of choice frequencies for trivial (€ 0.75) as (...) opposed to substantial (€ 18) amounts in Experiment 1 are quite accurate when they are presented with both conditions juxtaposed but are less accurate when only given one of the conditions. This result is interpreted to speak for the use of theory in prediction. In contrast people's predictions of the framing effect for substantial amounts (more risk seeking for positively than negatively framed problems) are accurate only for independent predictions but not for juxtaposed predictions, which speaks for the use of simulation.

According to the theory theory of folk psychology, our engagement in the folk psychological practices of prediction, interpretation and explanation draws on a rich body of knowledge about psychological matters. According to the simulation theory, in apparent contrast, a fundamental role is played by our ability to identify with another person in imagination and to replicate or re-enact aspects of the other person’s mental life. But amongst theory theorists, and amongst simulation theorists, there are significant differences of approach.

This paper is concerned. with the contrast between simulation- and deduction-based approaches to reasoning about physical objects. We show that linear logic can give a unified account of both simulation and deduction concerning physical objects; it also allows us to draw a principled distinction between simulation and deduction, since simulations correspond to cut-free proofs, whereas deductions correspond to proofs in general.

This paper is about the contemporary debate concerning folk psychology – the debate between the proponents of the theory theory of folk psychology and the friends of the simulation alternative.¹ At the outset, we need to ask: What should we mean by this term ‘folk psychology’?

Disagreeing with others about how to interpret a social interaction is a common occurrence. We often find ourselves offering divergent interpretations of others’ motives, intentions, beliefs, and emotions. Remarkably, philosophical accounts of how we understand others do not explain, or even attempt to explain such disagreements. I argue these disparities in social interpretation stem, in large part, from the effect of social categorization and our goals in social interactions, phenomena long studied by social psychologists. I argue we ought to expand (...) our accounts of how we understand others in order to accommodate these data and explain how such profound disagreements arise amongst informed, rational, well-meaning individuals.

Recent philosophical discussions of our capacity to attribute mental states to other human beings, and to produce accurate predictions and informative explanations of their behavior which make reference to the content of those states have focused on two apparently contrasting ways in which we might hope to account for these abilities. The first is that of regarding our competence as being under-girded by our grasp of a tacit psychological theory. The second builds on the idea that in trying to get (...) a grip on the mental lives of others we might be able to draw on the fact that we are ourselves subjects of mental states in order to simulate their mental processes. Call these the theory view and the simulation view. In this paper I wish to discuss an argument—which I shall call Collapse—to the effect that if our capacities can be explained in the way that the simulationist supposes then they can also be explained along lines that the advocate of the theory view favours. I am not the first person with simulationist sympathies to have addressed this argument. However, my response is somewhat less concessive than others in the literature: while they attempt to soften its force by attempting to reformulate the simulationist view in a way that evades the conclusion of the argument, I attempt to meet it head on and to show that it does not even succeed in refuting the version of simulationism which it takes as its target.

This paper explores the role and limits of cognitive simulation in understanding or explaining others. In simulation, one puts one's own cognitive processes to work on pretend input similar to that one supposes that the other plausibly had. Such a process is highly useful. However, it is also limited in important ways. Several limitations fall out from the various forms of cognitive diversity. Some of this diversity results from cultural differences, or from differences in individuals' cognitive biographies. Such diversity is (...) clearly important in history. Some sorts of such diversity are discussed, with attention to the results of contemporary cognitive science. It is argued that one must sometimes employ mixed (simulation-based/theory-based) strategies, and that sometimes what is done will be neither purely simulation nor purely theory-based. (shrink)

There is a paradox about how our social understanding develops if we take seriously both theory theory and the cognitivist dictum that all skilful interaction has robust conceptual underpinnings. On the one hand, it is clear that young infants demonstrate a capacity to reliably detect and respond to other’s intentions. For example, recent experimental evidence confirms that they have the capacity to appropriately parse what would otherwise be an undifferentiated behaviour stream at its mentalistic joints. If we follow the cognitivist (...) trend in thinking that having the appropriate concepts is an antecedent requirement for such recognitional capacities then it follows that we should ascribe to these infants the concept of intention (or, at least, a concept of intention). But if we also hold that mentalistic concepts are constituted by their links with other mentalistic concepts, such as belief and desire, as assumed by proponents of theory theory, then we ought to conclude that infants lack certain concepts, such as intention, because at their tender age they lack other concepts, such as belief, which are required to constitute their contents. I will consider two possible atomistic ways of squaring this circle, in the process ultimately rejecting cognitivism in favor of the idea that various nonconceptual capacities best account for our initial abilities for recognizing and responding to intentional agency. I hold that it is what these responses are directed at that remains common throughout the developments of our mentalistic concepts, enabling us to make sense of talk of conceptual change. Not only does this resolve the paradox with which theory theorists must content, it shows how we can start our folk psychological careers without a theory or even any concepts. (shrink)

We use a new model of metarepresentational development to predict a cognitive deficit which could explain a crucial component of the social impairment in childhood autism. One of the manifestations of a basic metarepresentational capacity is a ‘ theory of mind ’. We have reason to believe that autistic children lack such a ‘ theory ’. If this were so, then they would be unable to impute beliefs to others and to predict their behaviour. This hypothesis was tested using Wimmer (...) and Perner’s puppet play paradigm. Normal children and those with Down’s syndrome were used as controls for a group of autistic children. Even though the mental age of the autistic children was higher than that of the controls, they alone failed to impute beliefs to others. Thus the dysfunction we have postulated and demonstrated is independent of mental retardation and specific to autism. (shrink)

Thinking about the representational qualities of maps and models allows one to offer a new perspective on the nature of mindreading. The recent critiques of our dominant paradigms for mindreading, theory theory and simulation theory by enactivists such as Daniel Hutto reveal a flaw in the standard options for thinking about how we think about others. Views that rely on theorizing or simulation to account for the way in which we understand others often appear to over-intellectualize social interaction. In contrast, (...) enactivists champion embodied, non-representational forms of engagement with others. I claim that one can improve on the representational views of social cognition by moving away from talk of the mental manipulation of propositions in favor of the construction of maps and models of others. Furthermore, I claim that the current state of social neurobiology lends itself towards such a view. (shrink)

The paper first gives a conceptual distinction of the first, second and third person perspectives in social cognition research and connects them to the major present theories of understanding others (simulation, interaction and theory theory). It then argues for a foundational role of second person interactions for the development of social perspectives. To support this thesis, the paper analyzes in detail how infants, in particular through triangular interactions with persons and objects, expand their understanding of perspectives and arrive at a (...) self–other metaperspective. This allows them to grasp the other’s as well as their own perspective as such, which is equivalent to an explicit third person perspective and to an explicit first person perspective or self-consciousness. The paper describes the major steps towards these perspectives, pointing to a close interdependence of both developments. It argues that embodied second person interactions are not only an enabling, but the constitutive condition for the development of an explicit first and third person perspective. (shrink)

We argue that theory-of-mind (ToM) approaches, such as “theory theory” and “simulation theory”, are both problematic and not needed. They account for neither our primary and pervasive way of engaging with others nor the true basis of our folk psychological understanding, even when narrowly construed. Developmental evidence shows that young infants are capable of grasping the purposeful intentions of others through the perception of bodily movements, gestures, facial expressions etc. Trevarthen’s notion of primary intersubjectivity can provide a theoretical framework for (...) understanding these capabilities and his notion of secondary intersubjectivity shows the importance of pragmatic contexts for infants starting around one year of age. The recent neuroscience of resonance systems (i.e., mirror neurons, shared representations) also supports this view. These ideas are worked out in the context of an embodied “Interaction Theory” of social cognition. Still, for more sophisticated intersubjective interactions in older children and adults, one might argue that some form of ToM is required. This thought is defused by appeal to narrative competency and the Narrative Practice Hypothesis (or NPH). We propose that repeated encounters with narratives of a distinctive kind is the normal route through which children acquire an understanding of the forms and norms that enable them to make sense of actions in terms of reasons. A potential objection to this hypothesis is that it presupposes ToM abilities. Interaction Theory is deployed once again to answer this by providing an alternative approach to understanding basic narrative competency and its development. (shrink)

In this paper I defend interaction theory (IT) as an alternative to both theory theory (TT) and simulation theory (ST). IT opposes the basic suppositions that both TT and ST depend upon. I argue that the various capacities for primary and secondary intersubjectivity found in infancy and early childhood should not be thought of as precursors to later developing capacities for using folk psychology or simulation routines. They are not replaced or displaced by such capacities in adulthood, but rather continue (...) to operate as our ordinary and everyday basis for social cognition. I also argue that enactive perception rather than implicit simulation is the best model for explaining these capacities. (shrink)

I argue that there is no conflict between the simulation theory, once it is freed from certain constraints carried over from theory theory, and Gallagher's view that our primary and pervasive way of engaging with others rests on 'direct', non-mentalizing perception of the 'meanings' of others' facial expressions, gestures, and intentional actions.

The comment addresses central issues of a "theory theory" approach as exemplified in Gopnik' and Goldman's BBS-articles. Gopnik, on the one hand, tries to demonstrate that empirical evidence from developmental psychology supports the view of a "theory theory" in which common sense beliefs are constructed to explain ourselves and others. Focusing the informational processing routes possibly involved we would like to argue that his main thesis (e.g. idea of intentionality as a cognitive construct) lacks support at least for two reasons: (...) one methodological and one structural. On the other hand, Goldman raises an important question when he is asking how people ascribe mental states to themselves. Reasons why Goldman's attempt to understand common sense mental representations by using an analogy from visual perception is problematic are discussed. The role which is attributed to a phenomenology is evaluated. (shrink)

SHORT ABSTRACT: A number of accounts of the relationship between third-person mindreading and first-person metacognition are compared and evaluated. While three of these accounts endorse the existence of introspection for propositional attitudes, the fourth (defended here) claims that our knowledge of our own attitudes results from turning our mindreading capacities upon ourselves. The different types of theory are developed and evaluated, and multiple lines of evidence are reviewed, including evolutionary and comparative data, evidence of confabulation when self-attributing attitudes, phenomenological evidence (...) of “unsymbolized thinking”, data from schizophrenia, and data from autism.

In this dissertation an attempt is made to find a satisfactory account of the nature of commonsense psychological explanation of behavior. The starting point is the current debate in philosophy of mind between the theory theory of folk psychology and the simulation theory. The discussion in the first chapter shows that although simulationists claim that their view can replace the theory theory across the board, their arguments are directed merely at the strand of the theory theory that is to do (...) with the nature of the cognitive mechanism underlying our explanation-giving. ;In the second chapter the theory theory of the nature of commonsense psychological explanation is examined. The suggestion that the underlying motivation of theory theorists is that their view allows folk explanations to fit the covering law model is discussed and a proposal is made for the source of the type of law that is often put forward to play the role of commonsense psychological covering laws, i.e. ceteris paribus laws with completions in the vocabulary of some lower-level science. The viability of such a suggestion is weighed as is the suggestion that such laws are probabilisitic laws of one type or another. ;The third chapter lays out two well-known versions of the simulation theory of the cognitive mechanism that underlies our explanation-giving as well as the theoretical committments of each view. An attempt is then made to extend the simulation theory in order to provide it with a plausible formulation of simulation-based conditions for correct commonsense psychological explanation, a suggestion which is ultimately rejected. ;The fourth chapter summarizes the far-reaching implications of the arguments used in the rejection of the above two views and attempts to find an account of the nature of explanation that is satisfactory in that it draws the lines with respect to what qualifies as a correct commonsense psychological explanation where our pretheoretic intuitions tell us they should be and provides an answer to the questions that our preceding discussion has raised. A view that fills these two requirements is the view that says that a correct commonsense psychological explanation is one that cites the properties of states or events which, besides being causally and counterfactually relevant to the occurrence of the explanandum event, also satisfy certain conditions of pragmatic relevance, that is, reference to them provides true answers to commonsense 'why'-questions.

The predominant view in developmental psychology is that young children are able to reason with the concept of desire prior to being able to reason with the concept of belief. We propose an explanation of this phenomenon that focuses on the cognitive tasks that competence with the belief and desire concepts enable young children to perform. We show that cognitive tasks that are typically considered fundamental to our competence with the belief and desire concepts can be performed with the concept (...) of desire in the absence of competence with the concept of belief, whereas the reverse is considerably less feasible.

I argue that recent developments in animal cognition support the conclusion that HOT theory is consistent with animal consciousness. There seems to be growing evidence that many animals are indeed capable of having I-thoughts, including episodic memory, as well as have the ability to understand the mental states of others.
