A dissociation of right and left hemispheric effects for recognizing emotional tone and verbal content.
Emotionally intoned sentences (happy, sad, angry, and neutral voices) were dichotically paired with monotone sentences. A left ear advantage was found for recognizing emotional intonation, while a simultaneous right ear advantage was found for recognizing the verbal content of the sentences. The results indicate a right hemispheric superiority in recognizing emotional stimuli. These findings are most reasonably attributed to differential lateralization of emotional functions, rather than to subject strategy effects. No evidence was found to support a hypothesis that each hemisphere is involved in processing different types of emotion.
