Individual differences in vocabulary development may affect academic or social opportunities. It has been proposed that individual differences in word reading could affect the rate of vocabulary growth, mediated by the amount of reading experience, a process referred to as a Matthew effect (Stanovich, 1986).
In the current study, assessments of written word-reading skills in the 4th grade and oral vocabulary knowledge collected in kindergarten and in the 4th, 8th, and 10th grades from a large epidemiologically based sample (n = 485) allowed a test of the relationship of early word-reading skills and the subsequent rate of vocabulary growth.
Consistent with the hypothesis, multilevel modeling revealed the rate of vocabulary growth after the 4th grade to be significantly related to 4th-grade word reading after controlling for kindergarten vocabulary level, that is, above average readers experienced a higher rate of vocabulary growth than did average readers.
Vocabulary growth rate differences accumulated over time such that the effect on vocabulary size was large.
词汇发展中的个体差异可能会影响学业或社交机会。有人提出,单词阅读方面的个体差异可能会影响词汇增长速度,这一过程由阅读经验的多少介导,被称为马太效应(斯坦诺维奇,1986年)。
在本研究中,从一个基于流行病学的大样本(n = 485)中收集了四年级书面单词阅读技能评估以及幼儿园、四年级、八年级和十年级的口语词汇知识评估,从而能够检验早期单词阅读技能与随后词汇增长速度之间的关系。
与假设一致,多层模型显示,在控制了幼儿园词汇水平后,四年级后的词汇增长速度与四年级单词阅读显著相关,也就是说,阅读水平高于平均水平的读者比平均水平的读者经历了更高的词汇增长速度。
词汇增长率差异会随着时间积累,以至于对词汇量的影响很大。
