Children acquire language naturally, but there is variation in language acquisition patterns. Indeed, different internal and external variables play a role in acquiring language. However, there are open research questions about the contribution of different variables to language development. Moreover, with societal changes and due to the pandemic situation, there has been a growing interest in testing digitalization related to indirect language acquisition assessment. In this study, a web-based assessment survey was developed to (1) describe the relation between expressive vocabulary, Socio-Conversational Skills (SCS), gender, parental education, executive functions (EFs), and pretend play; (2) determine whether the survey can detect differences between late talkers (LTs) and children with typical language development; (3) identify children with "overall high" and "overall low" communicative-language scores to test the validity of expressive vocabulary as a main indicator to detect LTs. The parents of 108 Italian children (51 males) aged 24-36 months participated in the study. The results showed that expressive vocabulary correlates with measures of SCS (assertiveness and responsiveness) and is reliable in identifying LTs (d = 2.73). Furthermore, SCS and EFs contribute to better characterizing the developmental profile of children aged 24-36 months.
儿童自然而然地习得语言，但语言习得模式存在差异。事实上，不同的内部和外部变量在语言习得中发挥作用。然而，关于不同变量对语言发展的贡献仍存在一些开放性的研究问题。此外，随着社会的变化和大流行情况的出现，人们对与间接语言习得评估相关的数字化测试越来越感兴趣。在这项研究中，开发了一个基于网络的评估调查，以：(1)描述表达词汇、社交对话技能 (SCS)、性别、父母教育、执行功能 (EF) 和假装游戏之间的关系；(2)确定该调查是否可以检测出语言迟缓者 (LTs) 和具有典型语言发展的儿童之间的差异；(3)识别具有“整体高”和“整体低”交际语言分数的儿童，以测试表达词汇作为检测 LTs 的主要指标的有效性。研究招募了 108 名 24-36 个月大的意大利儿童（51 名男性）的家长参与。结果表明，表达词汇与 SCS（自信和响应性）的测量相关，并且能够可靠地识别语言迟缓者（d = 2.73）。此外，SCS 和 EF 有助于更好地描述 24-36 个月儿童的发展特征。
