Abstract (in Japanese) (See Japanese page) 
(in English) We examined the effects of complexity on the pattern’s encoding efficiency in the general population differing on Autism-spectrum Quotient (AQ) scores. We compared brain activity (electroencephalography) during a same-different task for High and Low AQ groups. The same-different task was composed of identical comparison (IC) and categorical comparison (CC) conditions that presented simple or complex patterns. We found that the P3b and positive slow wave (PSW) were elicited in both groups. In the CC condition, the Low AQ showed large P3b and PSW amplitudes with simple patterns than with complex patterns, whereas the High AQ showed the same amplitude levels for these patterns. These results indicate that, similar to simple patterns, complex patterns are sufficiently encoded in the High AQ.
