More than Words? Semantic Emotion Labels Boost Context Effects on Faces.

Semantic emotional labels can influence the recognition of isolated facial expressions. However, it is unknown if labels also influence the susceptibility of facial expressions to context. To examine this, participants categorized expressive faces presented with emotionally congruent or incongruent bodies, serving as context. Face-body composites were presented together, aligned in their natural form, or spatially misaligned with the head shifted horizontally beside the body-a condition known to reduce the contextual impact of the body on the face. Critically, participants responded either by choosing emotion labels or by perceptually matching the target expression with expression probes. The results show a label dominance effect: Face-body congruency effects were larger with semantic labels than with perceptual expression matching, indicating that facial expressions are more prone to contextual influence when categorized with emotion labels, an effect only found when faces and bodies were aligned. These findings suggest that the role of conceptual language in face-body context effects may be larger than previously assumed. © The Society for Affective Science 2021.
