Sixty pairs of dichotically presented CV syllables were administered to matched samples of bilingual Native American Crow and monolingual Anglo subjects. While sex and grade were not significant factors, a significant variance was found between the performance of the bilingual Native American Crow and the monolingual Anglo subjects. As predicted (1) the bilingual children demonstrated a more symmetrical cerebral representation for language processing than the monolingual children; and (2) the bilingual primary Crow speakers had a greater right hemisphere involvement in receptive language processing than the monolingual English speakers. Possible factors influencing these results are discussed.
向相匹配的美洲原住民克劳族双语样本和单语盎格鲁族受试者呈现了60对双耳分听的CV音节。虽然性别和年级不是显著因素，但在双语美洲原住民克劳族和单语盎格鲁族受试者的表现之间发现了显著差异。正如所预测的那样：（1）双语儿童在语言处理方面表现出比单语儿童更对称的大脑表征；（2）以克劳语为主要语言的双语者在接受性语言处理方面比单语英语使用者有更大的右半球参与度。文中讨论了影响这些结果的可能因素。
