Brief Report: Effect of Spatial Complexity on Visual Short-Term Memory and Self-Reported Autistic-Like Traits in Typically Developed Individuals / Junichi TAKAHASHI in Journal of Autism and Developmental Disorders, 43-7 (July 2013)

During each trial, nine-line segments with various orientations were arrayed in simple or complex configurations and presented in both memory and test displays. Typically, VSTM capacity decreases with increasing configuration complexity. We found that VSTM capacity for simple configurations was larger than for complex configurations in individuals reporting low AQ, whereas for individuals reporting high AQ, there were no significant differences between these configurations. These results suggest that the effects of spatial complexity on VSTM capacity could be observed in individuals reporting low AQ, but not in individuals reporting high AQ.

Differences in the Efficiency of Pattern Encoding in Relation to Autistic-Like Traits: An Event-Related Potential Study / Junichi TAKAHASHI in Journal of Autism and Developmental Disorders, 44-11 (November 2014)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 44-11 (November 2014) . - p.2895-2907 Titre : Differences in the Efficiency of Pattern Encoding in Relation to Autistic-Like Traits: An Event-Related Potential Study Type de document : Texte imprimé et/ou numérique Auteurs : Junichi TAKAHASHI, Auteur ; Daichi YASUNAGA, Auteur ; Jiro GYOBA, Auteur Article en page(s) : p.2895-2907 Langues : Anglais (eng) Mots-clés : Autism spectrum quotient  Complexity  Encoding efficiency  Event-related potential Index. décimale : PER Périodiques Résumé : We examined the effects of complexity on the efficiency of pattern encoding 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 task was composed of identical comparison and categorical comparison (CC) conditions that presented simple or complex patterns. In the CC condition, the Low AQ showed large P3b amplitudes with simple patterns than with complex patterns, whereas the High AQ showed the same amplitude levels for these patterns. These indicate that, similar to simple patterns, complex patterns are efficiently encoded in the High AQ. Moreover, the High AQ had no impairment in the global pattern encoding compared with the Low AQ.
