Abstract:

Slow potential EEG shifts SPSs recorded over Brocas area and the paired contralateral site preceding cued language acts have been reported to identify the language-dominant hemisphere. This method was applied to the comparative study of 10 hearing adults and 10 adult prelingually deaf persons whose first learned language was American Sign Language. Volunteers performed both language and non-language acts in both oral and manual expressive modes. The hearing group showed no lateralized SPS, failing to replicate previous reports. The deaf group showed a nonsignificant trend opposite in laterality to that of hearing groups in previous reports. Author
