Intermanual transfer means that training of one limb promote ability of other limb. The purpose of the study was to analyze that the direction of the intermanual transfer, whether difficulty of task affect or not and correlation between feedforward and the intermanual transfer through control of finger force by visuomotor information. 15 participants participated in this study and they were divided into 2 groups; right hand first and left hand first. The participants performed three types of task controlling pressing force: a feedforward task pressing suddenly until 5N, a straight task holding 5N and a curve task following sine curve. Participants showed that the intermanual transfer occurred only in the straight task which performed task of relatively low difficulty. In the straight task, the intermanual transfer occurred in not one way but two-way direction. In the feedback task, the intermanual transfer occured unlike that of in the feedforward task.
