Abstract

It is important to assess learning in both familiar and unfamiliar conditions to determine the extent of learning generalisation. In this study, we evaluated parent language outcomes of LENA Start™, a parent-implemented intervention, using distal measures derived from a parent–child free play interaction.

Forty-four parents and their child (mean: 20.8 months) participated in LENA Start™ or early childhood education curriculum intervention, in either English (n = 34) or Spanish (n = 10). We completed between- and within-group analyses using language and communication behaviour measures derived from parent–child interactions elicited outside the home with researcher-supplied materials (i.e., distal measures).

Group comparisons revealed significant differences on a subset of behavioural measures. Spanish-speaking parents in the LENA Start™ group demonstrated significant gains on three measures. While LENA Start™ has been associated with parent gains on proximal language measures, the results of this study reveal limited generalisation of skills based on distal measures.

利用亲子互动衍生的测量方法评估LENA Start™

评估在熟悉和不熟悉条件下的学习，以确定学习泛化的程度是很重要的。在这项研究中，我们评估了父母实施的干预措施LENA Start™的父母语言结果，采用了来自亲子自由游戏互动的远端测量。44位家长和他们的孩子（平均：20.8个月）参加了LENA Start™或早期儿童教育课程干预，英语（n = 34）或西班牙语（n = 10）。我们使用研究人员提供的材料（即远端测量），使用语言和交流行为测量方法，完成了组内和组间分析。这些测量方法来自于父母与孩子在家庭外的互动。组间比较显示，在行为测量的一个子集上存在显著差异。在LENA Start™组中，讲西班牙语的父母在三个指标上表现出显著的进步。虽然LENA Start™与父母在近端语言测量方面的收益有关，但本研究的结果显示，基于远端测量的技能泛化有限。

期刊介绍： A key publication in the field, Journal of Child Language publishes articles on all aspects of the scientific study of language behaviour in children, the principles which underlie it, and the theories which may account for it. The international range of authors and breadth of coverage allow the journal to forge links between many different areas of research including psychology, linguistics, cognitive science and anthropology. This interdisciplinary approach spans a wide range of interests: phonology, phonetics, morphology, syntax, vocabulary, semantics, pragmatics, sociolinguistics, or any other recognised facet of language study.
