microexpressions
Brief involuntary faces
Microexpressions are brief, involuntary facial movements that reveal emotions a person may be trying to conceal.
Lasting only a fraction of a second, they flash across the face before conscious control can suppress them.
The concept figures prominently in discussions of lie detection and emotional intelligence: Trained investigators learn to read microexpressions for signs of deception.
