Angry faces are important cues of threat that should be expected to be salient across cultures. In the current study we tested salience effects in a new manner, by comparing how long it took until anger and happiness ceased to be recognized in a dynamic flow of emotional expressions. Thirty Chinese and 30 European-American participants were asked to stop morphing movies that changed from an emotion expression to another, when they ceased to see the original emotion (anger vs. happiness). As expected, anger was cross-culturally seen longer than happiness. Moreover, participants saw anger longer on in-group than on out-group faces, suggesting that anger might sometimes signal threat of exclusion. Results are discussed considering the role of context in emotion perception.
