Individuals with developmental disorders, such as Autism Spectrum Disorder (ASD) or Attention Deficit/Hyperactivity Disorder (ADHD), tend to have atypical characteristics in visual information processing. Individuals with ASD often show superior performance on the Embedded Figures Test (EFT), which has been explained as indicating superior local processing in visual information processing. In the present study, 20 typically developing young adults (mean age, 21.61 years; SD, 1.62 years) completed the EFT and a set of Picture Completion Tests (PCTs) specifically made for this study. Relationships between performance in these tasks and individual differences in the Autism-Spectrum Quotient (AQ) and the Adult ADHD Self Report Scale (ASRS) were investigated. Multiple regression analysis revealed that high ASRS scores were linked to better EFT and worse PCT performance, while AQ scores did not affect either EFT or PCT performance. The results were discussed with relation to global/local processing of visual information.
