Although early intensive behavior interventions have been efficient in producing positive behavior outcome in young children with Autism Spectrum Disorder, there is a considerable variety in the children's progress. Research has suggested that parental and treatment factors are likely to affect children's response to treatment. The purpose of the current(More)
We conducted a longitudinal study of 30 preschool children with autism spectrum disorders (ASDs) to evaluate the potential benefits of the Treatment and Education of Autistic and related Communication Handicapped Children (TEACCH). Fifteen children following a low intensity TEACCH program were assessed four times for autism severity, adaptive functioning,(More)
Although recent studies have shown that catatonia can occur in patients with autism spectrum disorders (ASDs), the overlap of the behavioral features between these disorders raises many diagnostic challenges. In fact, in clinical practice it is common to misinterpret catatonic symptoms, including mutism, stereotypic speech, repetitive behaviors, echolalia,(More)
BACKGROUND Observing another person performing a complex action accelerates the observer's acquisition of the same action and limits the time-consuming process of learning by trial and error. Learning by observation requires specific skills such as attending, imitating and understanding contingencies. Individuals with autism spectrum disorder (ASD) exhibit(More)

Some key behavioural traits of Autism Spectrum Disorders (ASD) have been hypothesized to be due to impairments in the early activation of subcortical orienting mechanisms, which in typical development bias newborns to orient to relevant social visual stimuli. A challenge to testing this hypothesis is that autism is usually not diagnosed until a child is at(More)
The ability to imagine future events (episodic future thinking—EFT) emerges in preschoolers and further improves during middle childhood and adolescence. In the present study, we focused on the possible cognitive factors that affect EFT and its development. We assessed the ability to mentally project forward in time of a large cohort of 135 6- to(More)
