Recognition of facial expressions is influenced by emotional scene gist.

Recognition of facial expressions has traditionally been investigated by presenting facial expressions without any context information. However, we rarely encounter an isolated facial expression; usually, we perceive a person's facial reaction as part of the surrounding context. In the present study, we addressed the question of whether emotional scenes influence the explicit recognition of facial expressions. In three experiments, participants were required to categorize facial expressions (disgust, fear, happiness) that were shown against backgrounds of natural scenes with either a congruent or an incongruent emotional significance. A significant interaction was found between facial expressions and the emotional content of the scenes, showing a response advantage for facial expressions accompanied by congruent scenes. This advantage was robust against increasing task load. Taken together, the results show that the surrounding scene is an important factor in recognizing facial expressions.
