三个问题被问到，探讨语言微调假设和父母如何可能模型语言：（i）父母显着调整到他们的孩子的生产性语言或非语言认知在玩？(ii)唐氏综合征（DS）人群的语言调整水平与典型发育（TD）匹配人群相比是否不同？和（iii）两个群体在标签请求和对请求的脚手架响应方面是否不同？在探索性的游戏条件下，父母与DS儿童使用的平均话语长度（MLU）显着高于MLU使用的年轻TD儿童的父母谁匹配的MLU。因此，DS父母具有更高的基线MLU，但DS组中的非显著相关性不支持父母MLU调节。然而，有证据表明，当DS儿童处于接受性句法和非言语认知的较低和平均水平时，父母使用许多不同的单词来调整儿童的词汇。此外，DS和TD父母要求新玩具标签的频率相同，这可能表明所有父母群体仍在探索和建立他们孩子的词汇。这是一个重要的发现，因为它可能有助于解释为什么患有DS的青少年和年轻人的词汇理解能力比从他们的生产和非语言认知的测量中预测的要高。
Three questions were asked that explored the linguistic fine‐tuning hypothesis and how parents might model language: (i) do parents significantly tune to their children's productive language or non‐verbal cognition during play? (ii) is the level of the linguistic tuning different in the Down syndrome (DS) population compared to a typically developing (TD)‐match group population? and (iii) do the two populations differ in requests for labels and the scaffolding responses to the requests? In an exploratory play condition, parents of children with DS used a mean length of utterance (MLU) significantly higher than the MLU used by the parents of younger TD children who were matched for MLU. Thus, the DS parents have a higher baseline MLU, but the non‐significant correlations in the DS group do not support parental MLU tuning. There was evidence, however, for parental tuning to the children's lexicon using a number of different words when the DS children were at lower and average levels of receptive syntax and non‐verbal cognition. In addition, DS and TD parents requested labels for novel toys with the same frequency, perhaps indicting that all groups of parents are still probing and building their children's lexicons. This is an important finding because it may help to explain why adolescents and young adults with DS have vocabulary comprehension skills greater than one would predict from measures of their production and non‐verbal cognition.
