Conversational replies were examined in two groups of children with comparable vocabularies and speech limited to single-word utterances: children with specific language impairment, ages 2:10 to 3:6 (years:months); and children, ages 1:5 to 1:11, who were developing language normally. In interactions with adults the language-impaired children produced a greater number and variety of replies to both questions and statements than the normal-language children. The findings suggest that language-impaired children can serve as responsive conversationalists when syntactic skill is not a factor and that comprehension, world knowledge, and/or experience with conversations permit considerable variability in conversational skill even within the same level of expressive language ability.
一组是年龄在2岁10个月至3岁6个月的特定语言障碍儿童；另一组是年龄在1岁5个月至1岁11个月、语言发育正常的儿童。在与成人的互动中，语言障碍儿童对问题和陈述给出的回应在数量和种类上都比语言正常的儿童更多。研究结果表明，当句法技能不是一个影响因素时，语言障碍儿童可以成为有回应的对话者，并且即使在相同的表达语言能力水平内，理解能力、世界知识和/或对话经验也会使对话技能存在相当大的差异。
