Evidence for training the ability to read microexpressions of emotion

Microexpressions are extremely quick facial expressions of emotion that appear on the face for less than A1/2 a s. To date, no study has demonstrated that the ability to read them can be trained. We present two studies that do so, as well as evidence for the retention of the training effects. In Study 1 department store employees were randomly assigned to a training or comparison group. The training group had significantly higher scores than the comparison group in microexpression reading accuracy at the end of the training; 2 weeks later the training group had better third-party ratings of social and communicative skills on the job. Study 2 demonstrated that individuals trained in reading microexpressions retained their ability to read them better than a comparison group tested 2-3 weeks after initial training. These results indicated that the ability to read microexpressions can be trained and are retained.
