Abstract
This study investigated the relationship between autism-spectrum quotient and self and other face recognition. To examine the strength of attention to detail for self-faces, sixty-five undergraduate and graduate students answered a seven point scale on "how much the face looked like their own" for their unmodified, and four types of modified self-faces. Similarly, to examine the strength of attention to detail for other faces, the same participants viewed unfamiliar faces in a ten second video and then answered a seven point scale on "how much the face resembled the presented face" for unmodified and four types of modified other-faces. Subsequently, the participants completed the Autism Spectrum Quotient questionnaire (AQ). The results showed that the high AQ group showed a significantly lower evaluation value for "how much the face looks like their own" for the modified self-face compared to the low AQ group, but no significant difference was observed between the high and low AQ groups for "how much the presented face looks like the others" for modified other faces. In other words, Autism Spectrum affects the strength of attention to detail regarding one's own face, but does not affect attention to detail regarding other faces.
