Deficits in social functioning are a core feature of autistic spectrum disorders (ASD), being linked to various cognitive and developmental factors, but there has been little attempt to draw on normative models of social cognition to understand social behaviour in ASD. The current study explored the utility of Crick and Dodge’s (1994) information processing model to studying social cognition in ASD, and examined associations between social information processing patterns, theory of mind skills and social functioning. A matched-group design compared young people with Asperger syndrome with typically developing peers, using a social information processing interview previously designed for this purpose. The Asperger syndrome group showed significantly different patterns of information processing at the intent attribution, response generation and response evaluation stages of the information processing model. Theory of mind skills were found to be significantly associated with parental ratings of peer problems in the Asperger syndrome group but not with parental ratings of pro-social behaviour, with only limited evidence of an association between social information processing and measures of theory of mind and social functioning. Overall, the study supports the use of normative social information processing approaches to understanding social functioning in ASD.

ABSTRACT: BACKGROUND: One of the most consistent biological findings in autism is the elevated blood serotonin levels. Immune abnormalities, including autoimmunity with production of brain specific auto-antibodies, are also commonly observed in this disorder. Hyperserotonemia may be one of the contributing factors to autoimmunity in some patients with autism through the reduction of T-helper (Th) 1-type cytokines. We are the first to investigate the possible role of hyperserotonemia in the induction of autoimmunity, as indicated by serum anti-myelin-basic protein (anti-MBP) auto-antibodies, in autism. METHODS: Serum levels of serotonin and anti-MBP auto-antibodies were measured, by ELISA, in 50 autistic patients, aged between 5 and 12 years, and 30 healthy-matched children. RESULTS: Autistic children had significantly higher serum levels of serotonin and anti-MBP auto-antibodies than healthy children (P<0.001 and P<0.001, respectively). Increased serum levels of serotonin and anti-MBP auto-antibodies were found in 92% and 80%, respectively of autistic patients. Patients with severe autism had significantly higher serum serotonin levels than children with mild to moderate autism (P<0.001). Serum serotonin levels had no significant correlations with serum levels of anti-MBP auto-antibodies in autistic patients (P=0.39). CONCLUSIONS: Hyperserotonemia may not be one of the contributing factors to the increased frequency of serum anti-MBP auto-antibodies in some autistic children. These data should be treated with caution until further investigations are performed. However, inclusion of serum serotonin levels as a correlate may be useful in other future immune studies in autism to help unravel the long-standing mystery of hyperserotonemia and its possible role in the pathophysiology of this disorder.

This study explores the daily lives, particularly discretionary time, of adolescents with an autism spectrum disorder (ASD). We describe the activities and activity partners of adolescents, the factors associated with their discretionary time use, and the impact of time use on their autism symptoms. Mothers of 103 adolescents with an ASD completed two 24-hour time diaries to describe their adolescent’s activity participation during the third wave of a longitudinal study. Adolescents with an ASD spent considerable time in discretionary activities, with watching television and using a computer as the most frequent activities. They most frequently spent discretionary time alone or with their mothers. They spent little time engaged in conversations or doing activities with peers. Age, gender, the presence of intellectual disability, severity of autism symptoms and maladaptive behaviors, the number of siblings, maternal education, marital status, and family income were associated with adolescent time use. Notably, greater time spent in conversation and reading predicted future decreases in severity of social impairment. The way that adolescents with an ASD spend their free time may have implications for their development and the course of their autism symptoms.

This study examines Greek teachers’ perceptions related to the nature and management of autistic children. To investigate these issues, a statistically reliable number of questionnaires (n = 228) was distributed to a diversified teacher population. The questionnaire responses were analyzed statistically to identify the explanatory power of critical independent variables. The research findings support that teachers’ specialized training and working experience are critical inputs to improve teachers’ perceptions and efficient serving of autistic children. A cumulative joint effect of teachers’ previous specialized education and working experience working with autistic children was also indicated. This could be supportive of teachers upgrading their active leading role in team working with specialized scientific staff, parents and institutions on autistic children.

The aim of the present study was to investigate the influence of self-awareness of real-world behavior on treatment outcome in adolescents with ASD. For this purpose we followed 28 adolescents with ASD during their first year of specialized treatment. Results showed that better self-awareness at start of treatment was related with an increase in clinician-reported social functioning after 1 year of treatment. Additionally, an increase in self-awareness during treatment was related with a decrease of parent-reported problems in daily functioning. However, an increase in self-awareness was also related to an increase of self-reported daily and psychological problems. It is discussed that lowered self-awareness may result in an overestimation of personal real-world functioning and consequently may influence treatment course.
