Several studies have demonstrated that patients with right hemisphere damage, when compared with left-hemisphere-damaged controls, are impaired at comprehending emotional prosody. Critics of these studies, however, note that selection may have been biased because left-hemisphere-damaged subjects had good verbal comprehension.Objective
To learn whether a subject with a large left hemisphere stroke and global aphasia could comprehend emotional prosody in spoken material.Method
The authors formally tested speech and language with the Western Aphasia Battery and comprehension of emotional prosody and emotional facial expression with the Florida Affect Battery.Results
The patient could not perform verbally mediated tests but demonstrated spared ability to match emotional prosody to emotional facial expressions under a variety of conditions.Conclusions
These observations further support the idea that verbal and emotional communication systems are independent and mediated by different hemispheres.
