Relationship between adaptation of motor control and cognition of environmental dynamics.

This paper considers the analysis of dynamics of human operators when the environmental dynamics changes. When an operator conducts a task with his arm, the adaptation on his manipulating dynamics occurs according to the dynamics of environment. We assume that the adaptation has a certain relation to the cognition of the change of environmental dynamics. To confirm the assumption, we have planned the experiment in which subjects are required to perform several kinds of tracking tasks. It is shown in the experiment that the dynamics of manipulation correlates with the cognition of the change of environmental dynamics.
