This study compared the neuropsychological profiles of individuals with high-functioning autism (HFA) and Asperger's syndrome (AS). In comparison with matched controls, both groups were impaired on executive function tests. Only the HFA group demonstrated deficits in theory of mind and verbal memory, performing more poorly than both controls and AS subjects. These results suggest that: (1) HFA and AS are empirically distinguishable on measures independent of diagnostic criteria, and (2) impairment on theory of mind measures is not universally found among individuals with autistic spectrum conditions. The primacy of executive function and theory of mind deficits to autism is discussed.  相似文献

Abstract— The present study investigated theory of mind in two groups of autistic children with markedly different verbal mental ages but comparable nonverbal ability and chronological ages, using a range of theory of mind belief tasks. The aims were to look for evidence of developmental progression of theory of mind ability in autistic children and to examine the role played by verbal ability in task performance. The results showed hierarchical patterns of performance across tasks, suggesting a developmental sequence of emerging aspects of theory of mind ability. There was clear evidence that verbal ability is an important contributor to successful task performance.  相似文献

Theory of mind (ToM), the specific ability to attribute thoughts and feelings to oneself and others is generally impaired in schizophrenia. Previous studies demonstrated a deficit of the attribution of intentions to others among patients having formal thought disorder. During nonverbal tasks, such a function requires both the visual perception of human figures and the understanding of their intentions. These processes are considered to involve the superior temporal sulcus and the medial prefrontal cortex, respectively. Are the functional patterns of activation associated with those processes abnormal in schizophrenia? Seven schizophrenic patients on medication performed a nonverbal attribution of intentions task as well as two matched physical logic tasks, with and without human figures, while H2O15 PET-scanning was performed. Data from the patients were compared to those of eight healthy controls matched for verbal IQ and sex. The experimental design allowed dissociating the effect of the perception of human figures from that of the attribution of intentions. During attribution of intentions, significant activations in the right prefrontal cortex were detected in the control subjects. Those activations were not found in the schizophrenic group. However, in both groups, the perception of human figure elicited bilateral activation of the occipitotemporal regions and of the posterior part of the superior temporal sulcus. Schizophrenic patients performing a nonverbal attribution of intentions task have an abnormal cerebral activity.  相似文献

Abstract The aim of the present study was to assess the ability of 21 children and adolescents with Asperger syndrome (AS) of normal intelligence to infer mental states in a story context using Happés [15] Strange Stories test. The participants in the AS group were compared with an age-matched control group (N=20) of normally developing children and adolescents on a test of social understanding. The test material comprised social communication such as Pretence, Joke, Lie, White Lie, Figure of Speech, Misunderstanding, Persuasion, Irony, Double Bluff and Contrary Emotions, Appearance/Reality and Forgetting. As compared to the controls, the participants in the AS group performed less well on these tasks, and answered fewer correct mental state inferences, but performed well on a physical state control task. This study supports the main finding of earlier studies, showing that even individuals with AS of normal intelligence have problems in using mental state terms context-appropriately when tested on the Strange Stories test.  相似文献

Emanuel Miller lecture: confusions and controversies about Asperger syndrome   总被引:13,自引:0,他引:13  
BACKGROUND: Hans Asperger drew attention to individuals who show the core symptoms of autism in the presence of high verbal intelligence. METHODS: A review of the literature explores current issues concerning the diagnosis and nature of Asperger syndrome. RESULTS: The behavioural and neurophysiological evidence to date suggests that Asperger syndrome is a variant of autism typically occurring in high-functioning individuals, and not a separate disorder. One of the problems of diagnosis is that the typical impairment of social communication may be difficult to identify in early childhood, and can be camouflaged in adulthood by compensatory learning. The range and nature of the social impairments in Asperger syndrome are still in need of investigation, but appear to be less severe than in autism. Experimental evidence suggests that individuals with Asperger syndrome may lack an intuitive theory of mind (mentalising), but may be able to acquire an explicit theory of mind. Brain imaging studies pinpoint a network that links medial prefrontal and temporal cortex as the neural substrate of intuitive mentalising. This network shows reduced activation and poor connectivity in Asperger syndrome. While some individuals with Asperger syndrome have written eloquently about their lives, their ability to talk about their own emotions appears to be impaired (alexithymia). This impairment may be linked to depression and anxiety, which is common in adulthood. Little is as yet known about the often considerable cognitive strengths in Asperger syndrome, or about the difficulties observed in higher-level executive skills. CONCLUSIONS: Studies are needed that define the developmental course of the disorder and the nature of the strengths and weaknesses in both social and non-social domains. This requires more sensitive assessment instruments than are currently available. Questions about the prevalence of Asperger syndrome, about associated and secondary features, and about optimal education and management, urgently call for such studies.  相似文献
