Research carried out in the last two decennia has shown that right brain damage could disturb the production and reception of suprasegmentals. Dextrals with right hemispheric lesions may find it difficult to intone speech and/or to discriminate between various intonations or accentuations. However, right brain damage does not invariably entail some kind of dysprosody. Detailed investigation of a righthanded male with right temporo-parietal excision failed to uncover any prosodic deficit. Moreover, critical review of the positive cases reported so far indicates that dysprosody, when it occurs following injury to the right hemisphere, results from a neuro-motor deficit or from disturbed auditory discrimination. As a consequence, it cannot be considered a specific language disturbance. Moreover, dysprosody may also result from damage to the left hemisphere in dextrals. Accordingly, there is little evidence to support a recent claim that the right hemisphere is dominant for affective prosody in much the same way as the left hemisphere is dominant for propositional speech.
