In this study we report a convergence of behavioural and neuroanatomical evidence in support of an amygdala hypothesis of autism. We find that people with high-functioning autism (HFA) show neuropsychological profiles characteristic of the effects of amygdala damage, in particular selective impairment in the recognition of facial expressions of fear,(More)
In 2002, we published a paper [Brock, J., Brown, C., Boucher, J., Rippon, G., 2002. The temporal binding deficit hypothesis of autism. Development and Psychopathology 142, 209-224] highlighting the parallels between the psychological model of 'central coherence' in information processing [Frith, U., 1989. Autism: Explaining the Enigma. Blackwell, Oxford](More)
Two experiments were carried out assessing autistic children's recognition, discrimination, and fixation of unfamiliar faces and unfamiliar buildings. The experiments showed that (i) unfamiliar face recognition is impaired relative to normal peers, non-verbal ability matched and verbal ability matched controls. Relative to verbal ability matched controls(More)
Frith has argued that people with autism show "weak central coherence," an unusual bias toward piecemeal rather than configurational processing and a reduction in the normal tendency to process information in context. However, the precise cognitive and neurological mechanisms underlying weak central coherence are still unknown. We propose the hypothesis(More)
It has been suggested that language impairment in autism is behaviorally, neurobiologically, and etiologically related to specific language impairment (SLI). In this article, the authors review evidence at each level and argue that the vast majority of data does not support the view that language impairment in autism can be explained in terms of comorbid(More)
It is well established that certain aspects of play in young children are related to their emerging linguistic skills. The present study examined the relationships between functional play, symbolic play, non-verbal ability, and expressive and receptive language in normally developing children aged between 1 and 6 years using standardized assessment(More)
People with autism have consistently been found to outperform controls on visuo-spatial tasks such as block design, embedded figures, and visual search tasks. Plaisted, O'Riordan, and others (Bonnel et al., 2003; O'Riordan & Plaisted, 2001; O'Riordan, Plaisted, Driver, & Baron-Cohen, 2001; Plaisted, O'Riordan, & Baron-Cohen, 1998a, 1998b) have suggested(More)
Autistic people have specific memory difficulties. The effects of these difficulties on communication in relatively able autistic children and learning impaired controls were assessed in three experiments. The experiments tested the ability to: (1) carry out instructions; (2) ask questions without repetition; and (3) answer questions about past activities.(More)
Relatively able children with autism were compared with age- and language-matched controls on assessments of (1) familiar voice-face identity matching, (2) familiar face recognition, and (3) familiar voice recognition. The faces and voices of individuals at the children's schools were used as stimuli. The experimental group were impaired relative to the(More)
This experiment was designed to test the hypothesis that perceptual abnormalities in autism might be associated with alteration of induced gamma activity patterns overlying visual cortical regions. EEG was recorded from six adolescents with autism and eight controls matched on chronological age, and verbal and nonverbal mental age, whilst identifying the(More)
