Performance on a free-recall verbal dichotic listening task and cerebral dominance determined by the carotid amytal test.

Epileptic patients whose speech dominance had been ascertained using the carotid amytal technique were given a verbal dichotic listening test. Patients with left hemisphere speech dominance, like normal controls, showed a REA. Patients with right hemisphere speech representation, as a group, tended not to show a bias toward either ear. Moreover, repeated administrations of the verbal dichotic listening test yielded similar results.
