摘要

A series of experiments was conducted to evaluate the effects of dynamic facial expressions on judgments of emotion. The effects of contextual cues on emotional expression evaluation have been studied before, usually by pairing a situational description with a facial expression or presenting two contrasting facial expressions. Here, context was manipulated by creating dynamic faces, faces that morphed from one emotional expression to another. In this way, the effects of a preceding video clip on the interpretation of an emotional facial expression could be evaluated.;Results showed that dynamic facial expressions provided a salient contextual cue. The valence of neutral expressions was interpreted differently depending on the video clip preceding the expression. A neutral face at the end of an angry to neutral morph was rated positively whereas a neutral face at the end of a happy to neutral morph was rated negatively (Experiment 1A). The strength of this effect depended on the dynamic movement since bias effects were attenuated when the dynamic faces were replaced with static faces (Experiment 1B). Similar bias effects were observed for neutral faces and faces that were 25% emotive, but strongly emotional expressions were not susceptible to bias effects (Experiment 2). Different negative emotional expressions (angry vs. sad) had comparable effects on the subsequent judgment of a neutral face (Experiment 3). The duration of the dynamic video clips subtly modulated bias effects with longer durations leading to larger biases (Experiment 4). The degree to which static emotional faces affected expression judgment was manipulated by varying the exposure duration of the starting face and the delay between the starting face and the ending face (Experiment 5). These findings are similar to those from previous research exploring the effects of context on emotional facial expressions and bear some resemblance to representational momentum and face aftereffects.;Dynamic faces provided a new way to study the effect of context on emotional expression perception and emphasize the importance of considering both spatial and temporal contextual influences.
