This article presents the results of a lexical decision experiment in which the base frequency (BF) effect is explored in reading disabled children and skilled readers. Three groups of participants were created. The first group was composed of children with reading disorders, the second group of skilled readers matched with the first group for chronological age and the third group of skilled readers matched for vocabulary size. The results of the experiment showed strong effects for Group, BF and also for the Group by BF interaction. Children matched for chronological age with children with reading disorders were significantly faster and more accurate than children of the other groups, who did not show any difference from each other. The effect of BF showed that children responded faster to stimuli composed of frequent bases than to stimuli with less frequent bases. However, the analysis of the interaction between Group and BF showed that only the skilled readers matched to children with reading disorders for chronological age benefited from the BF effect. The results of the experiment are discussed in the framework of theoretical accounts of morphological processing in children as well as considering the role played by the experimental task.
本文呈现了一项词汇判断实验的结果，该实验旨在探究阅读障碍儿童和熟练读者的基本频率（BF）效应。研究创建了三组参与者。第一组由阅读障碍儿童组成，第二组由与第一组按年龄匹配的熟练读者组成，第三组由与词汇量匹配的熟练读者组成。实验结果显示出组间、BF 以及组间与 BF 相互作用的显著影响。与阅读障碍儿童按年龄匹配的儿童比其他组的儿童反应速度更快、准确性更高，而其他组的儿童之间没有差异。BF 的影响表明，儿童对由高频词组成的刺激反应更快，而对低频词组成的刺激反应较慢。然而，对组间与 BF 相互作用的分析表明，只有与阅读障碍儿童按年龄匹配的熟练读者从 BF 效应中受益。实验结果在儿童形态处理的理论解释框架内进行了讨论，同时考虑了实验任务所起的作用。
