This paper addresses issues of frequency and transparency in word recognition and their importance for the organization of the mental lexicon in Developmentally Language Impaired (DLI) francophones. A simple visual lexical decision task probes responses of DLI and control participants when presented with verbs. DLI participants are sensitive to whole-word frequency and show little or no transparency effects. These results are interpreted as indicating that words are not organized according to "morphological families" in the DLI mental lexicon, but rather according to a principle of frequency. These facts support the hypothesis that words in the DLI mental lexicon lack lexical features and morphological structure.
本文探讨了法语发育性语言障碍（DLI）患者在单词识别中的频率和透明度问题，以及它们对心理词库组织的重要性。一个简单的视觉词汇判断任务考察了DLI患者和对照组参与者在呈现动词时的反应。DLI患者对整词频率敏感，几乎没有或没有透明度效应。这些结果被解释为表明，在DLI心理词库中，单词不是按照“形态家族”组织的，而是按照频率原则组织的。这些事实支持了这样一种假设，即DLI心理词库中的单词缺乏词汇特征和形态结构。
