Dichotic test results for normal subjects and for temporal lobectomy patients

Test results obtained with Dichotic Consonant-Vowel (CV) test materials are reported for 50 normal subjects as well as for a total of 67 patients who underwent removal of the anterior portion of the right or left temporal lobe for control of seizures. All patients were tested before and after surgery. Results demonstrated that not all patients with temporal lobe seizures with subsequent temporal lobectomy demonstrated performance below the lower limits of normal established by the sample of normal subjects. Comparison of Dichotic CV and Staggered Spondaic Word test results is made on a subset of the patient population.
