Investigating appraisal-driven facial expression and inference in emotion communication.

Theory and research on emotion expression, both on production and recognition, has been dominated by a categorical emotion approach suggesting that discrete emotions are elicited and expressed via prototypical facial muscle configurations that can then be recognized by observers, presumably via template matching. This tradition is increasingly challenged by alternative theoretical approaches. In particular, appraisal theorists have suggested that specific elements of facial expressions are directly produced by the result of certain appraisals and have made detailed predictions about the facial patterns to be expected for these appraisal configurations.

Dynamic Facial Expression of Emotion and Observer Inference.

Research on facial emotion expression has mostly focused on emotion recognition, assuming that a small number of discrete emotions is elicited and expressed via prototypical facial muscle configurations as captured in still photographs. These are expected to be recognized by observers, presumably via template matching. In contrast, appraisal theories of emotion propose a more dynamic approach, suggesting that specific elements of facial expressions are directly produced by the result of certain appraisals and predicting the facial patterns to be expected for certain appraisal configurations.
