Comprehension of affective and nonaffective prosody.

We studied patients with damage of either the right (RHD) or left hemisphere (LHD) and control subjects to determine whether the RHD patients had a global or limited prosodic defect. Compared with LHD patients and controls, RHD subjects had decreased comprehension of emotional prosody. Both LHD and RHD groups had more impaired comprehension of propositional prosody than controls, but the RHD and LHD groups did not differ. The right hemisphere, therefore, seems to be dominant for comprehending emotional prosody but not propositional prosody.
