短时距估计中刺激物的动态变化效应

用两个实验考查了时距估计中刺激物的动态变化效应。结果发现,刺激物的运动、速度和旋转角度显著地影响着被试的时间判断,刺激物速度的时距延长效应对于较长时距(18s-24s)来说更加明显;运动刺激与较短、较准确的时距判断相关联;旋转角度的减少使得被试低估时距,而旋转角度的增加使得时距估计呈高估倾向。被试在时间估计过程中表现出长时距低估和短时距高估现象,本研究得到的时间估计转换点是11.4s,此点与先前的有关研究基本一致。

The Motion-change Effects of Stimulants on Short Duration Estimation

Two experiments were conducted to investigate the motion-change effects on short duration estimation.The results showed that motion speed and rotating angle significantly affected the subjects'time judgments,the duration-lengthened effects of stimulus speed in the longer duration(18s-24s) were more significant than in the shorter duration(6s-12s);the movement of stimulus corresponded to the short duration estimation and the accuracy of time judgments;with the decrease of the rotating angle,the subjects underestimated the duration,and with the increase of the rotating angle,the judgment of value of time increased.All subjects overestimated the shorter durations and underestimated the longer durations,the transational point in duration estimations computed in this study was 11.4s,which was the same as the result of past studies in some extent.
