这项研究跟踪了18名患有发育障碍的儿童，他们在研究开始时的年龄在3岁到6岁之间，历时两年。在最初的观察中，儿童主要通过语言前手势、发声和单字发声进行交流。儿童的语言技能每6个月通过修订后的沟通发展量表(D.E.Hedrick，E.M.Praise，&A.R.Tobin，1984)进行评估。在每一次观察中也测量了语言前传播率和父母的反应性。随着时间的推移，参与者之间的语言发展情况有所不同，这取决于他们的初级交流。分层线性模型表明，儿童的手势水平、沟通速度和父母反应偶然性是语言结果的显著预测因素。
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, & 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.
