The hemispheric alpha asymmetries of a group of normal males, normal females, fluent aphasic males and dysfluent aphasic males were investigated during the auditory presentation of sentences, a short story and a resting condition in the absence of linguistic stimuli. No differences were found for the groups' mean alpha ratio scores during the resting condition. Fluent aphasics were found to demonstrate greater right hemispheric alpha suppression than the other groups for the sentence and story conditions. The dysfluent aphasics showed greater right hemispheric alpha suppression for the sentence condition than either of the normal groups. Results are discussed in terms of the right hemisphere's contribution to language recovery following unilateral left hemispheric damage resulting in aphasia.
在句子、一篇短篇小说的听觉呈现过程中以及没有语言刺激的静息状态下，对一组正常男性、正常女性、流畅性失语男性和非流畅性失语男性的半球间阿尔法不对称性进行了研究。在静息状态下，未发现各组的平均阿尔法比率得分有差异。发现在句子和故事条件下，流畅性失语者比其他组表现出更大的右半球阿尔法抑制。在句子条件下，非流畅性失语者比任何一个正常组都表现出更大的右半球阿尔法抑制。根据右半球对单侧左半球损伤导致失语后语言恢复的贡献对结果进行了讨论。
