对80名3~6岁正常儿童和5名青壮年儿童，以不同的词语同时到达双耳(双耳听)和单耳(单耳听)的方式，观察了双耳和单耳分离能力的发展。结果表明，在双耳听的情况下，右耳识别的单词显著多于左耳。另一方面，在单耳听力中，每只耳朵的结果几乎是相同的。各年龄段儿童的单耳分离能力均低于双耳分离能力。双耳和单耳分离，能力随着年龄的增长而发展。6岁的儿童和年轻人取得的结果几乎是相同的。在3岁组，GILS在双耳分离能力和单耳分离能力上都优于男孩，但在年龄较大的年龄组中，男孩和女孩之间没有差异。
Paired spoken words were presented to 80 normal children with range from 3 to 6 years and 5 young, adults in such a way that different words arrived simultaneously at the two ears (dichotic listening) and at the one ear (monaural listening) to observe the development of dichotic and monaural separation abilities. The results demonstrated that in case of dichotic listening, significantly more words were recognized from the right ear than from the left ear. On the other hand, in monaural listening the results were almost identical for each ear. The monaural separation ability is inferior to the dichotic separation ability in all age groups. Dichotic and monaural separation, abilities develop as with ageing. Six-year old children and young adults achieve almost identioal results. In group age 3, gils are superior to boys on both dichotic and monaural separation abilities but there is no difference between boys and girls in the older age groups.
