The present study was aimed at investigating different aspects of Executive Functions (EF) in children with Developmental Dyslexia (DD). A neuropsychological battery tapping verbal fluency, spoonerism, attention, verbal shifting, short-term and working memory was used to assess 60 children with DD and 65 with typical reading (TR) abilities. Compared to their controls, children with DD showed deficits in several EF domains such as verbal categorical and phonological fluency, visual-spatial and auditory attention, spoonerism, verbal and visual short-term memory, and verbal working memory. Moreover, exploring predictive relationships between EF measures and reading, we found that spoonerism abilities better explained word and non-word reading deficits. Although to a lesser extent, auditory and visual-spatial attention also explained the increased percentage of variance related to reading deficit. EF deficits found in DD are interpreted as an expression of a deficient functioning of the Central Executive System and are discussed in the context of the recent temporal sampling theory.
本研究旨在探究发展性阅读障碍（DD）儿童执行功能（EF）的不同方面。我们使用神经心理学测试工具，包括词语流畅性、倒语、注意力、词语转换、短期记忆和工作记忆，评估了 60 名 DD 儿童和 65 名具有典型阅读（TR）能力的儿童。与对照组相比，DD 儿童在多个 EF 领域存在缺陷，如言语类别和语音流畅性、视觉空间和听觉注意力、倒语、言语和视觉短期记忆以及言语工作记忆。此外，我们还探讨了 EF 测量与阅读之间的预测关系，发现倒语能力可以更好地解释单词和非单词阅读缺陷。虽然程度较小，但听觉和视觉空间注意力也解释了与阅读缺陷相关的更多百分比的方差。在 DD 中发现的 EF 缺陷被解释为中央执行系统功能缺陷的表现，并在最近的时间采样理论背景下进行了讨论。
