Abstract
The purpose of this study is to investigate the effect of interaction between a leader and a follower on the higher brain function from the relation between the force applied by the operators and the activity level of the higher brain function. Subjects are labeled by the following three kinds of method; [Task 1] Subjects aren't designated the leader nor the follower, [Task 2] Each subject are designated the leader or the follower, and target points are shown to both of them, [Task 3] Each subject are designated the leader or the follower, and target points aren't shown to the leader but not to the follower. Higher brain function activity level in motor area is measured when operators perform above mentioned the three tasks. The experimental results showed that there were significant differences in the higher brain activity level between the leader and the follower.
