This study investigated the extent to which parental language input to children with hearing loss (HL) prior to cochlear implant (CI) differs from input to children with typical hearing (TH). A 20-min parent–child interaction sample was collected for 13 parent–child dyads in the HL group and 17 dyads in the TH group during free play. Ten minutes were transcribed and were coded for four variables: (a) overall utterances, (b) high-quality utterances, (c) utterances in response to child communicative acts (i.e., overall responses), and (d) high-quality utterances in response to child communicative acts (i.e., high-quality responses). Differences were detected for both quantity and quality of parental language input across the two groups. Early language skills correlated with three out of the four parental variables in both groups. Post hoc analyses suggested that the lower rate of high-quality responses in parents of children with HL could be attributed to lower intelligibility of child communication.

人工耳蜗植入前父母对听力损失儿童的话语和反应的数量和质量

本研究调查了在人工耳蜗植入 (CI) 之前，父母对听力损失 (HL) 儿童的语言输入与对典型听力 (TH) 儿童的输入有何不同。在自由玩耍期间，为 HL 组的 13 对亲子对子和 TH 组的 17 对子对收集了 20 分钟的亲子互动样本。十分钟被转录并被编码为四个变量：（a）整体话语，（b）高质量话语，（c）回应儿童交流行为的话语（即总体反应），以及（d）高质量话语回应儿童的交流行为（即高质量的回应）。检测到两组之间父母语言输入的数量和质量存在差异。早期语言技能与两组中四个父母变量中的三个相关。
