 We examined the relationship between the Wechsler Adult Intelligence Scale Ⅲ (WAIS-Ⅲ) and the Autism-Spectrum Quotient (AQ) in 30 Japanese patients with autism spectrum disorder (ASD) with average intelligence quotients (IQs). Patients with ASD showed higher abilities in verbal cognition than they did in other cognitive functions. Furthermore, the performance IQ and the picture arrangement scores of the WAIS-Ⅲ were positively correlated with the attention switching and communication scores of the AQ. The patients with ASD that had higher abilities for the performance IQ or picture arrangement had higher subjective difficulty. It is suggested that we should interpret the scores of the WAIS-Ⅲ and AQ carefully to use them as assistance tools for diagnosing ASD.
