Much of our communication is through body movements, facial expressions, and voice tones. Even seconds-long filmed slices of behavior can reveal feelings.

Women tend to read emotional cues more easily and to be more empathic. Their faces also express more emotion.

The meaning of gestures varies with culture, but facial expressions, such as those of happiness and sadness, are common the world over. Cultures also differ in the amount of emotion they express.

Research on the facial feedback effect shows that our facial expressions can trigger emotional feelings and signal our body to respond accordingly. We also mimic others’ expressions, which helps us empathize. A similar behavior feedback effect is the tendency of behavior to influence our own and others’ thoughts, feelings, and actions.
