| Research Abstract |
The purpose of the present study is to investigate whether manual asymmetries occur to response time(RT) and accuracy in pointing movement for visual target. In reaction time, the results indicate that the RT of the right hand is slower in left visual field than that in right visual field, and that the RT of the left hand is slower in right visual field than that in left visual field. In accuracy, the results show that in left visual field, the only vertical error of pointing movement is less than that in right visual field regardless of right or left hand, and that it is different from the typical S-R compatibility. In the present study, S-R compatibility was obtained in the only RT and not in the accuracy of the visually aimed movement. The findings in reaction time support popular interpretation of these manual asymmetries.
