The autism spectrum disorders (ASDs) are a group of conditions characterized by impairments in reciprocal social interaction and communication, and the presence of restricted and repetitive behaviours. Individuals with an ASD vary greatly in cognitive development, which can range from above average to intellectual disability. Although ASDs are known to be(More)
Neuropsychological and psychophysical studies report controversial results regarding local-global visual processing and motion perception in autism. Here, we investigate contour integration and motion perception in an accurately diagnosed sample of autistic children, using low-level psychophysical tasks. We measured detection thresholds for a closed chain(More)

Several studies on structural MRI in children with autism spectrum disorders (ASD) have mainly focused on samples prevailingly consisting of males. Sex differences in brain structure are observable since infancy and therefore caution is required in transferring to females the results obtained for males. The neuroanatomical phenotype of female children with(More)
SHANK3 is located on chromosome 22q13.3 and encodes a scaffold protein that is found in excitatory synapses opposite the pre-synaptic active zone. SHANK3 is a binding partner of neuroligins, some of whose genes contain mutations in a small subset of individuals with autism. In individuals with autism spectrum disorders (ASDs), several studies have found(More)
Although autism spectrum disorders (ASDs) have a substantial genetic basis, most of the known genetic risk has been traced to rare variants, principally copy number variants (CNVs). To identify common risk variation, the Autism Genome Project (AGP) Consortium genotyped 1558 rigorously defined ASD families for 1 million single-nucleotide polymorphisms (SNPs)(More)
Autism spectrum disorder (ASD) is a highly heritable disorder of complex and heterogeneous aetiology. It is primarily characterized by altered cognitive ability including impaired language and communication skills and fundamental deficits in social reciprocity. Despite some notable successes in neuropsychiatric genetics, overall, the high heritability of(More)
Visual cognition of observers with autism spectrum disorder (ASD) seems to show an unbalance between the complementary functions of integration and segregation. This study uses visual search and crowding paradigms to probe the relative ability of children with autism, compared to normal developments children, to extract individual targets from cluttered(More)
In this study, we have used an electrophysiological paradigm to investigate the neural correlates of the visual integration of local signals across space to generate global percepts in a group of low functioning autistic kids. We have analyzed the amplitude of key harmonics of the Visual Evoked Potentials (VEPs) recorded while participants observed(More)
BACKGROUND Child psychiatry has enjoyed a long tradition of using brief psychotherapy with children, but research on its efficacy and effectiveness in the setting of routine clinical care is remarkably sparse; the aim of this study was to evaluate the efficacy of an original model of brief psychodynamic psychotherapy (BPP) for children with emotional(More)
