This study followed 18 children with developmental disabilities, whose chronological ages were between 3 years and 6 years at the start of the study, over a 2-year period. At initial observation, children communicated primarily through prelinguistic gestures, vocalizations, and single-word utterances. Children's language skills were measured every 6 months with the Sequenced Inventory of Communication Development-Revised (D. E. Hedrick, E. M. Prather, and A. R. Tobin, 1984). Prelinguistic communication rate and parental responsiveness were also measured at each observation. Development of language over time differed between participants in accordance with their entry-level communication. Hierarchical linear modeling indicated that children's level of gestural attainment, rate of communication, and parent response contingency were significant predictors of language outcome.
本研究对18名发育障碍儿童进行了为期2年的跟踪，这些儿童在研究开始时的实际年龄在3岁至6岁之间。在初始观察时，儿童主要通过前语言手势、发声和单词表达进行交流。每6个月用修订后的《沟通发展顺序量表》（D.E.赫德里克、E.M.普拉瑟和A.R.托宾，1984年）对儿童的语言技能进行测量。每次观察时还测量前语言沟通率和家长反应性。随着时间的推移，不同参与者的语言发展因其初始沟通水平而异。分层线性模型表明，儿童的手势掌握水平、沟通率和家长反应的偶然性是语言结果的重要预测因素。
