The purpose of this study was to clarify the influence of the postural condition on themental rotation task of hands among people with autism spectrum disorder (ASD). Nine people with ASD and seventeen age-matched healthy people participated in this study. Based on a previous developmental study, it was hypothesized that ASD participants would show a larger effect of hand posture than healthy participants. Four line drawings of hands; palm and back view of both left and right hands were presented to the participants on the computer screen at four different rotation angles. (0°,90°,180°, and 270°) The participants were asked to answer whether the presented picture was the left or right hand in the two different hand conditions, the palms-up posture or the backs-up posture. The participants' response time (RT) and the percentage of the correct responses were analyzed by ANOVA. Percentage of the correct response showed that the simple main effect of posture was significant for the ASD but not for healthy group. That is, when participants' hands were in the backs-up posture, the ASD group was more accurate for the back-view stimulus than palm-view stimulus. Concerning RTs, the ASD group tended to respond faster when their posture and the stimulus were matching than when the two were mismatching (p<0.09 for backs-up posture, p< 0.2 for palms-up posture). In contrast, the postural effect on the healthy group was limited to the backs-up posture as reported by the previous research. Thus, in terms of both accuracy and speed, the posture may have a larger effect on people with ASD than healthy people. To show more clear-cut group differences, additional data with more ASD participants are needed.
