![]() ![]() ![]() In particular, we review the findings of the three main neuro-cognitive theories of autism: theory-of-mind deficit, weak central coherence and executive dysfunction. In this paper, recent developments in the field of autism are outlined. Individuals with autism may have difficulty seeing the ‘bigger picture’. It cannot, however, explain the non-social impairments and skills shown by people with autism. However, advances in these fields are expected as methodological difficulties are overcome. How autism affects seeing the ‘big picture’, Difficulties with Central Coherence. The hypothesis that people with autism have a specific deficit in ‘theory of mind’ has been successful in explaining the characteristic triad of social, communication and imagination impairments. The study of the behavioural and underlying cognitive deficits in autism has advanced ahead of the study of the underlying brain abnormalities and of the putative genetic mechanisms. Since a biological basis of autism was accepted, approaches from developmental cognitive neuroscience have been applied to further our understanding of the autism spectrum. However, the signs and symptoms of autism are still puzzling. The general public is now more aware of the high prevalence of this lifelong disorder, with ca. The consequences of this disorder for everyday life adaptation are extremely variable. ![]() Possible explanations for the clinical groups' weak central coherence are explored.Autism is a developmental disorder characterized by impaired social interaction and communication as well as repetitive behaviours and restricted interests. Of the two clinical groups, the autism group had the greater deficit, and it applied to the majority of the group. social-cognitive deficits (Frith, 2003 Happ and Frith, 2006. Individuals with an autistic disorder are less able to integrate visual elements. Happ and Ronald (2008) refer to the ‘satisfactory working theories for the various different aspects of autism’, namely, those that posit a specific ‘theory of mind’ deficit, executive dysfunction and weak central coherence (p. Key words: weak central coherence, autism spectrum disorders, visual processing. A second condition presented just a single piece of an object and participants were required to identify objects from a single piece.īoth clinical groups were significantly impaired in their ability to integrate pieces holistically, but they were unimpaired in their ability to identify an object from a single piece. The participants were required to conceptually integrate the fragments in order to identify the object. ![]() A modified version of the Hooper Visual Organisation Test was used in which line drawings depicting simple objects had been cut into pieces and arranged in a puzzle-like fashion. The strategy breaks down the learning of new concepts into small steps, which may be better suited to individuals with autism. All were normally intelligent and were matched with members of the general population of Cambridge. A new study suggests that a strategy called dynamic assessment may help individuals with autism transcend their central coherence deficits. Two groups with autistic disorder were recruited: adults with either autism or Asperger syndrome. Weak central coherence refers to the detail-focused processing style proposed to characterise autism spectrum disorders (ASD). Individuals with autism are thought to have weak central coherence so the prediction was that these individuals would show an impaired ability to integrate visual information. Visuoconceptual integration was explored as a test of central coherence theory (Frith, 1989). ![]()
