When emotions run high: A critical role for context in the unfolding of dynamic, real-life facial affect.

= 245) watched videos portraying reactions to real-life highly positive situations and evaluated the affective valence of the target. Video information was controlled by: (a) truncating the movies after 5, 10, or 20 seconds from the start, and by (b) digitally manipulating the videos such that only the face was visible with no context, only the context was visible with no face, or the face appeared in context. Results indicate that during real-life intense positive situations, facial expressions alone were rated as negative and failed to convey diagnostic information about the positive situational valence even at the most extended presentation durations. By contrast, when contextual information appeared alone or with the face, participants accurately rated the target as feeling positive, and this positivity increased with extended viewing duration. These findings suggests poor coupling between facial valence and felt emotions, supporting the notion that when emotions run high, the diagnostic power of facial expressions is reduced. Conversely, the findings demonstrate an inherent role for contextual information in the recognition of real-life intense faces. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
