Impaired diachronic thinking--(the propensity and capacity to think about events spreading across time)--was demonstrated in a 2-Phase study in which children with autism were compared with age and ability matched controls. Identical tests of diachronic thinking were administered in both phases of the study, but to different participant groups,…

This study examined gestalt perception in high-functioning autism (HFA) and its relation to tasks indicative of local visual processing. Data on of gestalt perception, visual illusions (VI), hierarchical letters (HL), Block Design (BD) and the Embedded Figures Test (EFT) were collected in adult males with HFA, schizophrenia, depression and…

This research is the first part of a 2-year cognitive-behavioral-ecological (CB-E) social skills training for high-functioning children with autism spectrum disorder (HFASD). Current study examined efficacy of an individual CB-E intervention in facilitating children's dyadic interactions (immediately after treatment and 4 months later) and their…

Children with autism exhibit deficits in the imitation and spontaneous use of descriptive gestures. Reciprocal Imitation Training (RIT), a naturalistic imitation intervention, has been shown to increase object imitation skills in young children with autism. A single-subject, multiple-baseline design across five young children with autism was used…

Many people with the diagnosis of Asperger syndrome (AS) show poorly developed skills in understanding emotional messages. The present study addressed discrimination of speech prosody in children with AS at neurophysiological level. Detection of affective prosody was investigated in one-word utterances as indexed by the N1 and the mismatch…

Hyperserotonemia is the most consistent serotonin-related finding in autism. The basis of this phenomenon, and its relationship to the central serotonergic dysfunction remains unclear. Platelet serotonin level (PSL) in 53 autistic adults and 45 healthy controls was measured. Mean PSL in autistic group (75.7 [plus or minus] 37.4 ng/[microliters])…

The effects of SMART Board technology, an interactive electronic whiteboard, and a 3s constant time delay (CTD) procedure was evaluated for teaching sight word reading to students with moderate intellectual disabilties within a small group arrangment. A multiple probe design across three word sets and replicated with three students was used to…

This study examines the decision-making process used for differential diagnosis of a sample of Hispanic children referred for autism spectrum disorders (ASDs). Of the sample of 28 children, 18 were diagnosed with ASDs. Of the 10 children who were not diagnosed with ASDs, 80% were found to have multiple diagnostic labels or comorbidities.…

This review discusses the laboratory and clinical research supporting the rationale for the efficacy of donepezil (Aricept[R] USA) in enhancing cognition in autism, Alzheimer disease, Down syndrome, traumatic brain injury, Attention Deficit Hyperactivity Disorder (ADHD), and schizophrenia. While preliminary animal models have shown effective,…

This paper identifies family characteristics associated with use of autism-related services. A telephone or in-person survey was completed during 2003-2005 by 383 North Carolina families with a child 11 years old or younger with ASD. Access to care is limited for racial and ethnic minority families, with low parental education, living in…

The effectiveness of a social skills training group for adolescents with Asperger syndrome and high-functioning autism (AS/HFA) was evaluated. Parents of six groups of adolescents (n = 46, 61% male, mean age 14.6) completed questionnaires immediately before and after the 12-week group. Parents and adolescents were surveyed regarding their…

Patients diagnosed with Autism Spectrum Disorder, show impaired integration of information across different senses. The processing-level from which this impairment originates, however, remains unclear. We investigated low-level integration of auditory and visual stimuli in subjects with Autism Spectrum Disorder. High-functioning adult subjects…

There is considerable controversy over reasons for observed increases in the prevalence of autism spectrum disorders. We examined trends in British Columbia education database coding of children with autism from 1996 to 2004. There was a significant linear increase in autism prevalence. The proportion of children identified by age 6 increased…

Children with Duchenne or Becker muscular dystrophy (MD) have delayed language and poor social skills and some meet criteria for Pervasive Developmental Disorder, yet they are identified by molecular, rather than behavioral, characteristics. To determine whether comprehension of facial affect is compromised in boys with MD, children were given a…

While deficits in social interaction are central to autism, the sibling relationship has been found to provide a key medium for the development of such skills. Naturalistic observations of sibling pairs including children with autism and controls with Down syndrome were made across two time periods, twelve months apart. Consistent with the…
