Using the Autism Quotient (AQ; Baron-Cohen et al., 2001), a 50-item scale that characterizes self-reported behaviors across five domains (social skills, attention switching, attention to detail, communication, and imagination), the average threshold of autistic traits was found to be elevated in Japan compared with the United Kingdom (Wakabayashi et al., 2006). Studies suggest that on a scale of 0 to 50, a Japanese person scores more than 4 points higher than those in the United Kingdom, although the clinical range for the AQ remains the same in both countries. This suggested that, on average, autistic traits were exhibited to a greater extent within the neurotypical Japanese population on existing measures.
