Abstract

We report findings from a corpus-based investigation of three young children growing up in German-English bilingual environments (M = 3;0, Range = 2;3–3;11). Based on 2,146,179 single words and two-word combinations in naturalistic child speech (CS) and child-directed speech (CDS), we assessed the degree to which the frequency distribution of CDS predicted CS usage over time, and systematically identified CS that was over- or underrepresented in the corpus with respect to matched CDS baselines. Results showed that CDS explained 61% of the variance in CS single-word use and 19.3% of the variance in two-word combinations. Furthermore, the bilingual nature of the over or -underrepresented CS was partially attributable to factors beyond the corpus statistics, namely individual differences between children in their bilingual learning environment. In two out of the three children, overrepresented two-word combinations contained higher levels of syntactic slot redundancy than underrepresented CS. These results are discussed with respect to the role that redundancy plays in producing semiformulaic slot-and-frame patterns in CS.

双语习得中的频率、冗余和语境
我们报告了一项基于语料库的调查结果,调查对象是在德英双语环境中长大的三名幼儿(M = 3;0,范围= 2;3 - 3;11)。基于自然儿童语音(CS)和儿童导向语音(CDS)中的2,146,179个单字和双字组合,我们评估了CDS的频率分布随时间变化对CS使用的预测程度,并系统地识别了相对于匹配的CDS基线,语料库中代表性过高或不足的CS。结果表明,CDS解释了61%的CS单词使用方差和19.3%的CS双词组合方差。此外,在语料库统计之外的因素,即儿童在双语学习环境中的个体差异,也可部分地归因于儿童在双语学习环境中的双语特性。在三个孩子中的两个中,过度代表的两个单词组合比代表性不足的CS包含更高水平的句法槽冗余。这些结果讨论了冗余在CS中产生半公式化的槽帧模式中所起的作用。

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.
