20 Navajo children were matched to 20 Anglo children according to sex, chronological age, and handedness at 2 different age levels. These matched subjects were administered 30 pairs of dichotically presented consonant-vowel (CV) syllables. An analysis of the children's performance on the dichotic task revealed that, while sex was not a factor, there was a distinct left-ear effect among the Navajo children as compared with the expected right-ear effect as found with the Anglo children. Furthermore, a developmental trend was evidenced. These results suggest that there are developmental preferences among Navajo children in processing receptive language in the right cerebral hemisphere. This oppositional preference is thought to be related to the linguistic characteristics of the Navajo language.
根据性别、实足年龄和用手习惯，在两个不同年龄水平将20名纳瓦霍儿童与20名盎格鲁儿童进行匹配。这些匹配的受试者接受了30对双声道呈现的辅音-元音（CV）音节测试。对儿童在双耳分听任务中的表现进行分析后发现，性别不是一个因素，但与盎格鲁儿童中预期的右耳效应相比，纳瓦霍儿童中存在明显的左耳效应。此外，还证明了一种发展趋势。这些结果表明，纳瓦霍儿童在右半球处理接受性语言时存在发展偏好。这种相反的偏好被认为与纳瓦霍语的语言特征有关。
