Expression is an important nonverbal act of human expressing their emotional information. Studies have found that the ability to recognize facial expression of the major depressive disorder (MDD) are damaged. The reaction time for recognizing sad expression is longer, and shows a severe negative tendency. As a result, depression patients may not accurately identify subtle changes on facial expression under social situations. Micro-expression is a facial expression which is difficult to detect. It leaks when one tries to suppress or hide his true feelings but it is very short and can not be controlled by himself. In this study, we are trying to examine if there are difference when depression patients discriminate micro一expression compared with that of macro expression. We used two groups, clinical and subclinical depression patients, to examine their difference with healthy people when identifying macro expression, quick expression and micro-expression.
In study 1，we investigated the characteristics of facial expression recognition in subclinical depression patients. Using three research paradigms, we investigate the accuracy difference between inclination to depression graduate students and healthy ones in recognizing macro expression, transient expression, and micro-expression. We Found that there was no significant accuracy difference in identifying macro and BART between the two group, but in the micro-expression test, the accuracy of inclination to depression graduate students i0ecognizing sad expression was significantly lower than that of healthy ones. The HAMD score was correlated with the accuracy of positive expression recognition in BART.
In order to further verify whether the ability of expression recognition between depression patients and healthy people are different, we used clinical subjects instead of subclinical ones in Study 2. we selected hospital-diagnosed depression patients and healthy people, using the carne three tests as the first study, and found that the accuracy of expression recognition of depression patients was generally lower than that of healthy people. On macro expression recognition, there was significant accuracy difference in recognizing 100% happy, neutral and 100% sadness faces There was also significant accuracy difference on recognizing neutral expression in BART. However, in the improved JACBART，there was a significant Performed accuracy difference on sad expression recognition. Depression patients worse In micro-expression recognition than that in the macro expression recognition.
Through the above two studies, we found that depression patients recognized expression and micro-expression worse than healthy people. Clinical and subclinical people were different from healthy ones in recognizing negative expression, which is an important discovery of our study. Previous studies have focused on examining the depression patients recognizing common facial expression (ie, macro-expression), and there is no empirical study on micro-expression recognition. This study fills the gaps in studying micro-expression in depression patients, which provides a new enlightenment for studying micro-expression research in the future.
