Discrimination and identification of emotions in human voice by brain-damaged subjects.

Discrimination and identification of emotions in human voice was studied in normal controls and in 4 groups of brain-damaged subjects, subdivided along the right/left and anterior/posterior dimensions. Results showed a failure of right-brain-damaged patients, the right posterior group being significantly worse than all the other groups. Qualitative differences emerged as well: both a conceptual and an acoustic deficit seem to contribute to right posterior patient performance.
