Robinson, Sally; Goddard, Lorna; Dritschel, Barbara; Wisley, Mary; Howlin, Pat – Brain and Cognition, 2009
Executive dysfunction is a characteristic impairment of individuals with Autism Spectrum Disorders (ASD). However whether such deficits are related to autism per se, or to associated intellectual disability is unclear. This paper examines executive functions in a group of children with ASD (N = 54, all IQ greater than or equal to 70) in relation…

Krysko, Krysko M.; Rutherford, M. D. – Brain and Cognition, 2009
Identifying threatening expressions is a significant social perceptual skill. Individuals with autism spectrum disorders (ASD) are impaired in social interaction, show deficits in face and emotion processing, show amygdala abnormalities and display a disadvantage in the perception of social threat. According to the anger superiority hypothesis,…

Bernier, R.; Dawson, G.; Webb, S.; Murias, M. – Brain and Cognition, 2007
Imitation ability has consistently been shown to be impaired in individuals with autism. A dysfunctional execution/observation matching system has been proposed to account for this impairment. The EEG mu rhythm is believed to reflect an underlying execution/observation matching system. This study investigated evidence of differential mu rhythm…

Kemner, C.; van der Geest, J. N.; Verbaten, M. N.; van Engeland, H. – Brain and Cognition, 2007
The looking behavior of children with pervasive developmental disorder (PDD) and age- and IQ-matched normal control children was studied using infrared oculography. Stimuli varying in complexity and topic were presented to test whether children with PDD have specific abnormalities in looking behavior to complex stimuli and/or to faces. All…

Mackinlay, Rachael; Charman, Tony; Karmiloff-Smith, Annette – Brain and Cognition, 2006
High functioning children with a diagnosis of autism or Asperger's syndrome (HF-ASD) often experience difficulties organising goal-directed actions in their day-to-day lives, requiring support to schedule daily activities. This study aimed to capture these everyday difficulties experimentally using multitasking, a methodology that taps into the…

Klin, Ami; Jones, Warren – Brain and Cognition, 2006
The weak central coherence (WCC) account of autism characterizes the learning style of individuals with this condition as favoring localized and fragmented (to the detriment of global and integrative) processing of information. This pattern of learning is thought to lead to deficits in aspects of perception (e.g., face processing), cognition, and…
