Previous research on the effects of word-level factors on lexical acquisition has shown that frequency and concreteness are most important. Here, we investigate CDI data from 1,030 Dutch children, collected with the short form of the Dutch CDI, to address (i) how word-level factors predict lexical acquisition, once child-level factors are controlled, (ii) whether effects of these word-level factors vary with word class and age, and (iii) whether any interactions with age are due to differences in receptive vocabulary. Mixed-effects regressions yielded effects of frequency and concreteness, but not of word class and phonological factors (e.g., word length, neighborhood density). The effect of frequency was stronger for nouns than predicates. The effects of frequency and concreteness decreased with age, and were not explained by differences in vocabulary knowledge. These findings extend earlier results to Dutch, and indicate that effects of age are not due to increases in vocabulary knowledge.

早期词汇习得的决定因素:单词和儿童水平因素对荷兰儿童单词习得的影响

先前关于词级因素对词汇习得影响的研究表明,频率和具体性是最重要的。在这里,我们调查了来自 1,030 名荷兰儿童的 CDI 数据,这些数据使用荷兰语 CDI 的缩写形式收集,以解决(i)一旦儿童水平因素得到控制,单词水平因素如何预测词汇习得,(ii)这些因素的影响是否单词级别的因素随单词类别和年龄而变化,以及 (iii) 与年龄的任何交互是否是由于接受词汇的差异。混合效应回归产生频率和具体性的影响,但不是词类和语音因素(例如,词长、邻域密度)的影响。频率对名词的影响比谓词强。频率和具体性的影响随着年龄的增长而降低,并没有用词汇知识的差异来解释。这些发现将早期的结果扩展到荷兰语,并表明年龄的影响不是由于词汇知识的增加。
