Spontaneous sign-language samples were collected in a controlled interactive situation from 20 young hearing-impaired children and their mothers. Inflectional morphemes in the samples were described by cher attributes and classified for syntactic function within utterances. Inflectional morpheme productivity did not increase significantly with age; mean manual English morphemes per utterance did increase with age. The first six inflectional morphemes used by the children studied were the same as those used by normal-hearing children. A good predictor of the child's use of inflectional morphemes was the mother's use of these morphemes.
在可控的互动情境中,收集了20名听力受损儿童及其母亲的自发手语样本。通过特征描述样本中的屈折语素,并对其在话语中的句法功能进行分类。屈折语素的产出能力并未随年龄显著增加;平均每个话语中的人工英语语素数量确实随年龄增长。所研究儿童使用的前六个屈折语素与听力正常儿童使用的相同。儿童对屈折语素的使用情况的一个良好预测指标是母亲对这些语素的使用情况。
