A differing bidirectional impact on the recognition accuracy of facial expression

Area of Science:

• Psychology
• Cognitive Neuroscience
• Social Psychology

Background:

• Facial expression recognition is crucial for social interaction.
• Previous research has explored unidirectional influences on facial expression perception.
• The interplay between observer feedback and sender cues remains less understood.

Purpose of the Study:

• To investigate the bidirectional influence of observer and sender on facial expression recognition accuracy.
• To examine how an observer's facial feedback modulates expression recognition.
• To determine the effect of sender's facial features (mouth openness) on recognition accuracy.

Main Methods:

• A facial manipulation task was employed with Chinese participants.
• Observer facial feedback effects on expression recognition were assessed.
• Sender's mouth openness (open/closed) impact on recognition was analyzed.

Main Results:

• Recognition accuracy for sad facial expressions was uniquely affected by both sender and observer bidirectional cues.
• Sender's mouth openness influenced recognition of happy and neutral faces, but not observer's bodily state.
• Bidirectional impacts on facial expression recognition varied between emotional and neutral expressions.

Conclusions:

• The bidirectional influence on facial expression recognition is expression-dependent.
• Observer feedback and sender cues interact dynamically in social perception.
• Understanding these bidirectional effects is key to comprehending social cognition.
