ToM tasks consisted of mistaken identity and contents tasks, two versions of unintended transfer tasks, and an emotional false-belief task. Attention problems were assessed using parent and teacher reports of behavior and child omission errors on the Continuous Performance Test (CPT). Auditory working memory was assessed using two subtests of the Woodcock–Johnson Psycho-Educational Battery—Revised. Impulsivity was assessed using parent and teacher reports of behavior, the Dimensional Change Card Sort (DCCS), commission errors on the CPT, and Luria's Hand Game (LHG). Controlling for age, language, and socioeconomic status (SES), ToM was significantly related to aggregate scores for attention problems, memory, impulsivity, and an overall executive functioning aggregate of all three components. In addition, parent and teacher ratings of social problems were negatively related to both ToM and overall executive functioning. Executive functioning and ToM may be indicators of metacognitive deficits that underlie social problems in clinical samples of children with disruptive behavior and attention problems.

First we summarize our evidence demonstrating teleological action explanations in one-year-olds. Then we shall briefly contrast the structure of teleological vs. causal mentalistic action explanations and outline four logical possibilities concerning the nature of the developmental relationship between them. We shall argue for the view that causal mentalistic action explanations are constructed as useful theoretical extensions of the earlier, purely teleological, nonmentalistic interpretational stance. Q: Why did the chicken cross the road? A1: To get to the other side. A2: It wanted to be on the other side.

Executive function abilities in autism and Tourette syndrome: An information processing approach

The performance of non-retarded autistic children was compared with that of two matched control groups, one with Tourette Syndrome and the other developmentally normal. Autistic subjects performed as well as controls on tasks requiring global-local processing and inhibition of neutral responses. In contrast to both control groups, however, the autistic sample was significantly impaired on a measure of cognitive flexibility. The performance of children with Tourette Syndrome did not differ from that of normal controls on any task. These results refine our knowledge about executive dysfunction in autism and suggest a new conceptual framework and general method for investigating the cognitive underpinnings of neurodevelopmental disorders.

A recent model of psychological sex differences suggests that this is a major dimension in which the sexes differ, with males being more drawn to systemize than females. Currently, there are no self-report measures to assess this important dimension. A second major dimension of sex differences is empathizing (the drive to identify mental states and respond to these with an appropriate emotion). Previous studies find females score higher on empathy measures. We report a new self-report questionnaire, the Systemizing Quotient (SQ), for use with adults of normal intelligence. It contains 40 systemizing items and 20 control items. On each systemizing item, a person can score 2, 1 or 0, so the SQ has a maximum score of 80 and a minimum of zero. In Study 1, we measured the SQ of n = 278 adults (114 males, 164 females) from a general population, to test for predicted sex differences (male superiority) in systemizing. All subjects were also given the Empathy Quotient (EQ) to test if previous reports of female superiority would be replicated. In Study 2 we employed the SQ and the EQ with n = 47 adults (33 males, 14 females) with Asperger syndrome (AS) or highfunctioning autism (HFA), who are predicted to be either normal or superior at systemizing, but impaired at empathizing. Their scores were compared with n = 47 matched adults from the general population in Study 1. In Study 1, as predicted, normal adult males scored significantly higher than females on the SQ and significantly lower on the EQ. In Study 2, again as predicted, adults with AS/HFA scored significantly higher on the SQ than matched controls, and significantly lower on the EQ than matched controls. The SQ reveals both a sex difference in systemizing in the general population and an unusually strong drive to systemize in AS/HFA. These results are discussed in relation to two linked theories: the 'empathizingsystemizing' (E-S) theory of sex differences and the extreme male brain (EMB) theory of autism.

This was done by investigating whether children with autism would rapidly and automatically enumerate a number of dots presented in a canonical form, or count each dot individually to obtain the total. The time taken to count stimuli was compared across three participant groups: children with autism, children with moderate learning difficulties, and normally developing children. There were 22 children in each group, and individuals were matched across groups on the basis of verbal mental age. Results implied that children with autism did show a tendency towards an analytic level of processing. However, though the groups differed on measures of counting speeds, the number or children showing patterns of global or analytic processing did not differ significantly across the groups. Whether these results implicate a weak drive for central coherence in autism, which is both specific to, and pervasive in the disorder, is discussed.

We report structural MRI data on 15 high-functioning individuals with autistic disorder. A voxel-based whole brain analysis identi®ed grey matter differences in an amygdala centered system relative to 15 age-and IQmatched controls. Decreases of grey matter were found in anterior parts of this system (right paracingulate sulcus, left inferior frontal gyrus). Increases were found in posterior parts (amygdala/peri-amygdaloid cortex, middle temporal gyrus, inferior temporal gyrus), and in regions of the cerebellum. These structures are implicated in social cognition by animal, imaging and histopathological studies. This study therefore provides converging evidence of the physiological basis of social cognition.

Despite this, we argue that even adults do not reliably use this sophisticated ability for the very purpose for which it is designed, to interpret the actions of others. In Experiment 1, a person who played the role of "director" in a communication game instructed a participant to move certain objects around in a grid. Before receiving instructions, participants hid an object in a bag, such that they but not the director would know its identity. Occasionally, the descriptions that the director used to refer to a mutually-visible object more closely matched the identity of the object hidden in the bag. Although they clearly knew that the director did not know the identity of the hidden object, they often took it as the referent of the director's description, sometimes even attempting to comply with the instruction by actually moving the bag itself. In Experiment 2 this occurred even when the participants believed that the director had a false belief about the identity of the hidden object, i.e. that she thought that a different object was in the bag. These results show a stark dissociation between an ability to reflectively distinguish one's own beliefs from others', and the routine deployment of this ability in interpreting the actions of others. We propose that this dissociation indicates that important elements of the adult's theory of mind are not fully incorporated into the human comprehension system. q

A new theory, the empathizing-systemizing (E-S) theory, is summarized, which argues two factors are needed to explain the social and nonsocial features of the condition. This is related to other cognitive theories such as the weak central coherence theory and the executive dysfunction theory. The E-S theory is also extended to the extreme male brain theory as a way of understanding the biased sex ratio in autism. Etiological predictions are discussed, as are the clinical applications arising from the E-S theory.

We report a patient, B.M., with early and temporally sequence behaviour. The findings are discussed with reference to models regarding the role of or congenital left amygdala damage who, by adulthood, had received the psychiatric diagnoses of schizophrenia the amygdala in the development of theory of mind and the degree of dissociation between theory of mind and and Asperger's syndrome. We conducted a series of experimental investigations to determine B.M.'s cognitive executive functioning. We conclude that theory of mind is not simply a function of more general executive functioning. In line with his diagnoses, B.M. was found to be severely impaired in his ability to represent mental functions, and that executive functions can develop and function on-line, independently of theory of mind. states. Following this, we conducted a second series of studies to determine B.M.'s executive functioning.

The intentional stance is a component of a broader social cognitive function, mentalizing. Here we report a study that investigates the neural substrates of "on-line" mentalizing, using PET, by asking volunteers to second-guess an opponent. In order to identify brain activity specifically associated with adoption of an intentional stance, we used a paradigm that allowed tight control of other cognitive demands. Volunteers played a computerised version of the children's game "stone, paper, scissors." In the mentalizing condition volunteers believed they were playing against the experimenter. In the comparison condition, volunteers believed they were playing against a computer. In fact, during the actual scanning, the "opponent" produced a random sequence in both conditions. The only difference was the attitude, or stance, adopted by the volunteer. Only one region was more active when volunteers adopted the intentional stance. This was in anterior paracingulate cortex (bilaterally). This region has been activated in a number of previous studies involving mentalizing. However, this is the first study suggesting a specific link between activity in this brain region and the adoption of an intentional stance. © 2002 Elsevier Science (USA)

The three principal approaches to explaining this development--theory theory, modular theory, and simulation theory--are described first. Next comes a description of infant precursors or protoforms of theory-of-mind knowledge in infancy, including a beginning awareness of the intentionality and goal-directedness of human actions. This discussion is followed by a summary of the postinfancy development of children's understanding of visual perception, attention, desires, emotions, intentions, beliefs, knowledge, pretense, and thinking. Briefly considered next are intracultural, intercultural, and interspecies differences in theory-of-mind development. The chapter then concludes with some guesses about the future of the field.
