Kawakami, Sayaka; Uono, Shota; Otsuka, Sadao; Yoshimura, Sayaka; Zhao, Shuo; Toichi, Motomi – Journal of Autism and Developmental Disorders, 2020
The present study examined the relationship between multisensory integration and the temporal binding window (TBW) for multisensory processing in adults with Autism spectrum disorder (ASD). The ASD group was less likely than the typically developing group to perceive an illusory flash induced by multisensory integration during a sound-induced…

Using the Japanese version of the Wechsler Intelligence Scale for Children-Third Edition (WISC-III), 26 girls with high-functioning (IQ greater than or equal to 70) pervasive developmental disorders (HFPDD) (mean age, 8.2 years) were compared with 116 boys with HFPDD (mean age, 9.0 years). Compared with the boys, the girls scored significantly…

Wakabayashi, Akio; Baron-Cohen, Simon; Uchiyama, Tokio; Yoshida, Yuko; Tojo, Yoshikuni; Kuroda, Miho; Wheelwright, Sally – Journal of Autism and Developmental Disorders, 2007
In the current study, the child AQ was administered in Japan, to examine whether the UK results for reliability and validity generalize to a different culture. Assessment groups were: Group 1: n = 81 children with Asperger Syndrome (AS) or high-functioning autism (HFA); Group 2: n = 22 children diagnosed PDD-NOS with average IQ; and Group 3: n =…

Wakabayashi, Akio; Baron-Cohen, Simon; Wheelwright, Sally; Tojo, Yoshikuni – Journal of Autism and Developmental Disorders, 2006
The AQ (Autism-Spectrum Quotient) is a self-administered instrument for measuring the degree to which an adult with normal intelligence has the traits associated with the autistic spectrum. The AQ was administered in Japan to test whether the UK results would generalize to a very different culture. Three groups of subjects, adults with AS or HFA…

Analysis of diagnostic questionnaires completed by Japanese parents of 141 autistic children below the age of 12 found that the Japanese peak of abnormal social behavior, including autistic symptoms as reported by parents, was from the ages of 3 to 9 years as compared with the U.S. and European peak of 3 to 6 years.
