Abstract
Auditory tests and informal speech evaluations were performed on 4 patients with right infantile hemiplegia before and after removal of the abnormal left cerebral hemisphere. Both pre-and postoperative tests showed normal thresholds for pure tones and for speech in both ears. The ability to identify relatively difficult words presented at intensities above threshold was impaired in the right ear, contralateral to the pathologic hemisphere. The patients'' speech, while somewhat lacking in proper control of loudness or tempo, gave no evidence of aphasia. Vocabulary and language were commensurate with intellectual capacity and level of education. Speech was not affected adversely by the surgery.
