本研究的目的是探讨表情持续时间对微表情识别的影响，微表情与欺骗密切相关。在两个实验中，参与者被简短地（从20毫秒到300毫秒）展示了六种基本表情中的一种，然后被要求识别这种表情。结果表明，被试对微表情的识别能力随着表情持续时间的增加而增加，在200 ms时达到一个转折点，然后趋于平稳。结果还表明，练习可以提高参与者的表现。本研究结果表明，微表情持续时间的适当上限可能在1/5秒左右，并证实了通过练习可以增强识别微表情的能力。
The purpose of this study was to investigate the effects of the duration of expressions on the recognition of microexpressions, which are closely related to deception.In two experiments, participants were briefly (from 20 to 300 ms) shown one of six basic expressions and then were asked to identify the expression.The results showed that the participants' performance in recognition of microexpressions increased with the duration of the expressions, reaching a turning point at 200 ms before levelling off. The results also indicated that practice could improve the participants' performance.The results of this study suggest that the proper upper limit of the duration of microexpressions might be around 1/5 of a second and confirmed that the ability to recognize microexpressions can be enhanced with practice.
