摘要：

Gaze-shift dynamics of unrestrained seated subjects were examined. The subjects participated in two tasks, In the first task, they tapped sequences of 3-D targets located on a table in front of them, In the second task, they only looked at similar sequences of targets. The purpose of the task (tapping vs only looking) affected the dynamics of gaze-shifts. Gaze and eye-in-head peak velocities were higher and gaze-shift durations were shorter during tapping than during looking-only. We conclude that task variables affect gaze-shift dynamics, altering characteristics of the so-called saccadic ''main sequence'', (C) 1997 Elsevier Science Ltd.
