计算机控制心理学实验过程的计时误差分析

TIMING ERROR ANALYSIS IN COMPUTER-CONTROLLED PSYCHOLOGICAL EXPERIMENTS

计算机在控制心理学实验过程中，可能引入各种潜在的计时误差，特别在短时呈现各种实验刺激时，有些误差是不应忽略的。本文重点分析屏幕刷新率对实验设计的限制及可能产生的计时误差和解决方法。

In the process of controlled psychological experiment,the computer may introduce various potential timing errors.Some of the errors should not be ignored,especially when the experimental stimuli occur in a short period.This article mainly analysed the limit of the screen refresh rate to the experimental design and the timing error that might occur,as well as the methods for solving these problems.
