微表情训练工具(METT)对中国被试的有效性研究

An Effectiveness Study of the training tools of micro expression (METT)

目的:检验METT对中国被试的有效性。方法:通过使用METT软件对63名中国大学生进行训练,比较训练前后微表情识别能力的差异。结果:被试使用METT进行训练后,其微表情识别能力提高非常显著(t=8.577,p<0.001),后测较前测得分提高14%;女生微表情识别能力的提高程度要大于男生(p<0.05)。结论:微表情训练工具(METT)对中国被试的训练是有效的。

Micro-expression is a kind of expressions and different from common expressions. Micro-expressions＇ duration is very short and usually considered to be 1/25 of a second to 1/5 of a second. The ability to detect micro-expression is an important skill for understanding a person＇s true emotional state. The researcher called Ekman made a micro-expression training tool（METT）in order to improve the recognition capability of micro expressions. This experiment selected 63 Chinese college students as subjects,and used METT to train the skills to detect their micro-expression. The experimental results showed that the trained grades improved significantly and the grades of post test increased 14% than the pretest.The grades had no significant difference between untrained male and female students. The trained grades of female students improved significantly more than male students.It concluded that the METT was effective for Chinese subjects and female students could have higher improvement on the ability of micro- expression recognition than male students.
