研究心理时间在运动刺激上的非稳定特征，探讨心理时间和空间维度的动态关联。被试根据屏幕呈现的多种运动刺激，复制运动时间。结果表明：直线、弧线、未封闭圆环、未封闭方框四种运动形状，前两者运动时间的反应值显著高于后两者；直线和弧线的比较中，时距的主效应显著，从左到右、从上到下两方向反应值的均值显著高于从右到左、从下到上；对弧线运动的时间估计，相比较与其运动轨迹等长的直线运动，更加接近于与其弦长等长的直线运动。

This study explored the unstable characteristics of psychological time on moving stimulus to indicate some link between psychological time and space in dynamic conditions. Subjects reproduced the duration of movement displayed on the monitor. The results showed that:(1) the reproduced duration of line and arc was significantly higher than nonocclusive circle and square;(2) contrasting line and arc, the main effect of duration was significant and the mean reproduced duration on direction of left-to-right and up-to-down was significantly higher than right-to-left and down-to-up;(3) The time estimation of arc movement was more close to the linear movement with the arc length than the chord length.
