Posers were requested to produce happy and sad emotional expressions, deliberately accentuated on the left and right sides of the face. Raters judged the emotional intensity of expressions when presented in original and mirror-reverse orientation. Left-side-accentuated sad expressions were rated as more intense than right-side-accentuated sad expressions. Raters were biased to judge expressions as more intense when the accentuated side was to their left. The findings indicated that the perceiver bias in weighting information from the side of the face in left hemispace extends to judgments of emotional intensity.
