Both the amount and responsiveness of adult language input contribute to the language development of autistic and non-autistic children. From parent-child interaction footage, we measured the amount of adult language input, overall parent responsiveness, and six discrete parent responsive behaviours (imitations, expansions, open-ended questions, yes/no questions, comments and acknowledgements) to explore which types of responsiveness predicted autistic preschoolers' language five months later, after controlling for adult language input. We found expansions and particularly imitations to be more important for later language than overall responsiveness. This study emphasises the need to capture what exactly about parent language input influences child language acquisition, and adds to the evidence that imitating and expanding early language might be particularly beneficial for autistic preschoolers.
成人语言输入的数量和反应能力都有助于自闭症和非自闭症儿童的语言发展。从亲子互动的片段中，我们测量了成人语言输入的数量、整体家长反应能力以及六种不同的家长反应行为（模仿、扩展、开放式问题、是非问题、评论和认可），以探讨哪些类型的反应能力可以预测自闭症学龄前儿童五个月后的语言能力，在控制成人语言输入的情况下。我们发现扩展，特别是模仿，对后来的语言比整体反应能力更重要。这项研究强调了需要捕捉到关于家长语言输入到底是什么影响了孩子的语言习得，并增加了证据表明模仿和扩展早期语言可能对自闭症学龄前儿童特别有益。
