Local and Global Visual Processing in Autism Spectrum Disorders (Van Eylen et al, 2015, JADD e-pub)

Local and global visual processing abilities and processing style were investigated in individuals with autism spectrum disorder (ASD) versus typically developingi ndividuals, children versus adolescents and boys versus girls. Individuals with ASD displayed more attention to detail in daily life, while laboratory tasks showed slightly reduced global processing abilities, intact local processing abilities, and a more locally oriented processing style. However, the presence of these group differences depended on particular task and sample (i.e., age and gender) characteristics. Most measures of local and global processing did not correlate with each other and were not associated with processing style. Significant associations between local–global processing and ASD symptom severity were observed, but the causality of these associations remains unclear.
