Differential contributions of the two cerebral hemispheres to the perception of happy and sad faces

Abstract Emotional and neutral facial expressions of the same individual were presented simultaneously, one to each visual field, and subjects were required to identify the side containing the affective face. Reaction time was faster to right vs left visual field presentations when the expression was happy and vice versa when it was sad. The data support the hypothesis of differential hemispheric specialization for positive and negative emotion.
