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)

Introduction -- Evidence from children -- Evidence form infants and non-human animals -- Evidence from neuroimaging and neuropsychology -- Evidence from adults -- The cognitive basis of mindreading -- Elaborating and applying the theory.

Various dichotomies have been proposed to characterize the nature and development of human mindreading capacities, especially in light of recent evidence of mindreading in infants aged 7 to 18 months. This article will examine these suggestions, arguing that none is currently supported by the evidence. Rather, the data support a modular account of the domain-specific component of basic mindreading capacities. This core component is present in infants from a very young age and does not alter fundamentally thereafter. What alters with (...) development are the interactions between core mindreading and other systems, including executive systems, and forms of learning that do not require radical conceptual change.

The lack of consensus on how to characterize humans’ capacity for belief reasoning has been brought into sharp focus by recent research. Children fail critical tests of belief reasoning before 3 to 4 years (Wellman, Cross, & Watson, 2001; Wimmer & Perner, 1983), yet infants apparently pass false belief tasks at 13 or 15 months (Onishi & Baillargeon, 2005; Surian, Caldi, & Sperber, 2007). Non-human animals also fail critical tests of belief reasoning but can show very complex social behaviour (e.g., (...) Call & Tomasello, 2005). Fluent social interaction in adult humans implies efficient processing of beliefs, yet direct tests suggest that belief reasoning is cognitively demanding, even for adults (e.g., Apperly, Samson & Humphreys, 2005). We interpret these findings by drawing an analogy with the domain of number cognition, where similarly contrasting results have been observed. We propose that the success of infants and non-human animals on some belief reasoning tasks may be best explained by a cognitively efficient but inflexible capacity for tracking belief-like states. In humans this capacity persists in parallel with later-developing, more flexible but more cognitively demanding theory of mind abilities. (shrink)

To date, emotion research has primarily focused on the experience and display of the emoter. However, of equal, if not more, importance is how such displays impact and guide the behavior of an observer. We incorporate a functionalist framework of emotion to examine the development of differential responding to discrete emotion, theorize on what may facilitate its development, and hypothesize the functions that may underlie such behavioral responses. Although our review is focused primarily on development, the theoretical and methodological ideas (...) laid out are relevant for researchers of emotion at all ages. (shrink)

In two experiments, we investigated whether 13-month-old infants expect agents to behave in a way consistent with information to which they have been exposed. Infants watched animations in which an animal was either provided information or prevented from gathering information about the actual location of an object. The animal then searched successfully or failed to retrieve it. Infants’ looking times suggest that they expected searches to be effective when—and only when—the agent had had access to the relevant information. This result (...) supports the view that infants’ possess an incipient metarepresentational ability that permits them to attribute beliefs to agents. We discuss the viability of more conservative explanations and the relationship between this early ability and later forms of ‘theory of mind’ that appear only after children have become experienced verbal communicators.

We review recent anticipatory looking and violation-of-expectancy studies suggesting that infants and young preschoolers have spontaneous (implicit) understanding of mind despite their known problems until later in life on elicited (explicit) tests of false-belief reasoning. Straightforwardly differentiating spontaneous and elicited expressions of complex mental state understanding in relation to an implicit-explicit knowledge framework may be challenging; early action predictions may be based on behavior rules that are complementary to the mentalistic attributions under consideration. We discuss that the way forward for (...) diagnosing early mentalism is to analyze whether young candidate mind-readers’ visual orienting cohere across different belief-formation by belief-use combinations. Adopting this formal cognitive analysis, we conclude that whilst some studies come tantalizingly close to sign-posting mentalism in infants and young children’s spontaneous responses, the bulk of evidence for early mentalism grades into behaviorism.
