| Outline of Final Research Achievements |
Difficulties to avoid obstacles are frequently be observed in individuals with autism spectrum disorders (ASD). We hypothesized that these features are linked to atypical peripersonal space surrounding their body. Ide & Hidaka (2013) have reported that temporal order judgements (TOJ) of visuo-tactile stimuli becomes difficult when they see a line-drawing of a hand. In the current study, we found that the phenomenon of degraded visuo-tactile temporal resolution by visibility of a body part less occur in neurotypical individuals with higher autistic traits. We also found that a case of ASD had excessively higher temporal resolution at 10 times in comparison with neurotypical individuals. These results would indicate that the excessively superior or inferior temporal resolution of sensory stimuli, and resulting difficulty to integrate them, is underlying of atypical peripersonal space of body in individuals with ASD.
