Previous research into face processing in autism spectrum disorder (ASD) has revealed atypical biases toward particular facial information during identity recognition. Specifically, a focus on features (or high spatial frequencies [HSFs]) has been reported for both face and nonface processing in ASD. The current study investigated the development…

Daily living skills (DLS), such as personal hygiene, meal preparation, and money management, are important to independent living. Research suggests that many individuals with autism spectrum disorder exhibit impairments in daily living skills relative to their cognitive skills. This study examined predictors of daily living skills attainment and…

The aim of our study was to compare two neurodevelopmental disorders (Williams syndrome and autism) in terms of the ability to recognize emotional and nonemotional facial expressions. The comparison of these two disorders is particularly relevant to the investigation of face processing and should contribute to a better understanding of social…

We used neuropsychological tasks to investigate integrity of brain circuits linking orbitofrontal cortex and amygdala (orbitofrontal-amygdala), and dorsolateral prefrontal cortex and hippocampus (dorsolateral prefrontal-hippocampus), in 138 individuals aged 7-18 years, with and without autism. We predicted that performance on…

Background: It is not known whether those with co-morbid fragile X syndrome (FXS) and autism represent a distinct subtype of FXS; whether the especially severe cognitive delays seen in studies of young children with co-morbid FXS and autism compared with those with only FXS continue into adolescence and young adulthood; and whether autism in those…

Examined empathy and conservation abilities of nonretarded children with autism and compared their performance to that of normally developing children. Autistic children performed surprising well, but not as well as normal children. There was a closer association between cognitive abilities and affective understanding among the autistic children…

Evaluation of 17 children with autism at the ages of 6 to 15 and then again at ages 13 to 25, suggested that, for the majority of people with autism, there may be little development of a theory of mind. For a minority, development may extend to the equivalent of a 3- to 4-year-old level by the teenage years. (JDD)

Sixteen individuals with autism and sixteen with Down's Syndrome, aged 10-29, were matched for verbal mental age. The groups' scores did not differ on the Vineland Adaptive Behavior Scales. However, the adaptive skills of Down's Syndrome individuals kept pace with mental age, while the skills of autistic subjects did not change. (Author/JDD)

The usefulness of the Preschool Preposition Test (PPT) as a cognitive screening and diagnostic tool for handicapped children is demonstrated through results of eight independent studies. The subjects were 354 children and youths, aged two to 20 years, with various handicaps: mentally retarded, autistic-like, moderately emotionally disturbed,…
