Words are processed in both a global and local manner. Studies on global versus local processing styles in individuals with and without dyslexia are inconclusive. In the present study, we investigated whether distinct patterns of global/local visual processing were associated with more precisely defined dyslexia profiles. Previous studies on dyslexia provide evidence of accuracy- and rate-based subtypes, with impairment in one dimension alongside normal performance in the other. In the current study, three groups of adult readers: rate disability, accuracy disability, typical development, were presented with nonlinguistic global /local congruency task. The results revealed that the rate disability group had deficiencies performing the global task while the accuracy disability group had deficiencies in the local task. These results are discussed in the context of global/local word processing and in relation to dyslexia. Specifically, they suggest that different patterns of global/local processing are observed between different types of dyslexics, and imply that practitioners should modify their treatment based on the specific deficiency.
单词的处理方式既有整体的也有局部的。关于有阅读障碍和无阅读障碍个体的整体与局部处理方式的研究尚无定论。在本研究中，我们调查了不同的整体/局部视觉处理模式是否与更精确界定的阅读障碍类型相关。先前关于阅读障碍的研究提供了基于准确性和速度的亚型证据，即一个维度受损而另一个维度表现正常。在当前研究中，三组成年读者：速度障碍组、准确性障碍组、典型发育组，参与了非语言的整体/局部一致性任务。结果显示，速度障碍组在执行整体任务时有缺陷，而准确性障碍组在局部任务中有缺陷。这些结果将在整体/局部单词处理的背景下并与阅读障碍相关联进行讨论。具体而言，它们表明不同类型的阅读障碍者之间观察到了不同的整体/局部处理模式，这意味着从业者应根据特定缺陷调整他们的治疗方法。
