以往的研究表明，认知控制功能有助于词汇干扰的解决。发展性阅读障碍（DD）的特征是认知控制（CC）缺陷和快速自动化阅读（RAN）任务中词汇提取速度的降低，但这些缺陷之间的关系以及它们与阅读问题之间的关系尚不完全清楚。为了研究这个问题，我们测试了青少年DD（n = 38），穷人的读者（PR; n = 25）和典型的读者（TR; n = 33）匹配的年龄和智商，在CC功能与Stroop，停止信号，西蒙，向后数字跨度和n-back任务和词汇检索和词汇冲突解决与RAN的图片在语义上同质与混合试验。正如预期的那样，在被阻止的RAN任务中，DD个体比TR参与者表现出更长的命名时间和更大的词汇冲突解决效果（通过同质和混合条件下命名时间的差异分数来指标）。我们还发现了CC措施的显着组间差异（TR = PR > DD）。阅读时间与认知能力有关，而词汇干扰效应与这组能力没有任何联系。这些结果表明，DD个体在多个认知功能，如认知控制，词汇提取和词汇冲突解决的障碍。我们的研究结果还表明，CC功能参与词汇提取，但我们还没有发现证据表明，他们参与词汇冲突解决过程。
Previous studies have revealed that cognitive control functions contribute to the resolution of lexical interference. Both cognitive control (CC) deficits and reduced speed of lexical retrieval in Rapid Automatized Naming (RAN) tasks are characteristics of Developmental Dyslexia (DD), but it is still not fully understood how these deficits relate to each other and to reading problems. To examine this question, we tested adolescents with DD (n = 38), poor readers (PR; n = 25) and typical readers (TR; n = 33) matched on age and IQ, on CC functions with Stroop, Stop Signal, Simon, Backward Digit Span and n-back tasks and on lexical retrieval and lexical conflict resolution with RAN of pictures in semantically homogeneous vs. mixed trials. As expected, in the blocked RAN Task DD individuals showed longer naming times and a greater effect of lexical conflict resolution (indexed by difference scores of naming times in the homogeneous and mixed conditions) than TR participants. We also found significant group differences (TR = PR > DD) in CC measures. Naming time was associated with CC, while the lexical interference effect did not show any association with this set of abilities. These findings suggest that DD individuals show impairments in multiple cognitive functions, such as cognitive control, lexical retrieval and lexical conflict resolution. Our results also suggest that CC functions are involved in lexical retrieval, but we have not found evidence for their involvement in lexical conflict resolution processes.
