Abstract (in Japanese) (See Japanese page) 
(in English) We examined the effects of spatial complexity defined by Garner’s rotation and reflection transformation principle on the capacity of visual short-term memory (VSTM) in individual differences along the Autism-spectrum Quotient (AQ) by using a change-detection task. On each trial, 9 line segments contained several orientations (0°, 45°, 90°, or 135°) were displayed in simple (ESS 1), medium (ESS 4), and complex (ESS 8) configurations (Howe, 1980). The participants (n = 28) were asked whether the orientations of line segments between two displays were same or different. On the basis of the AQ scores, the participants were divided into the groups with high AQ (n = 13) and low AQ (n = 12). The results showed that the VSTM capacity in the high AQ was larger than that in the low AQ in ESS 8. Moreover, we found that the effects of spatial complexity on the VSTM capacity were observed in the low AQ, but not in the high AQ (Experiment 1). These results were caused not by the differences in the rating ability of spatial complexity between the high and low AQ, but by the differences in the VSTM capacity between the high and low AQ (Experiment 2). We assumed that these results reflected the functional disconnectivity between processing of spatial configuration and VSTM capacity in the high AQ.
