Subjects' extrapolations of a piecewise constant-velocity trajectory and constant-acceleration were mapped out over sequence trials that required only button-press response. Without any performance feedback, subjects' both trajectories approximated an acceleration segment followed by segment. With the approached optimal performance. Subsequent withdrawal feedback shifted entire extrapolated trajectory. These feedback-related changes in can be interpreted as two parameters cognitive representation movement pattern.
