比较了14名法国阅读障碍儿童在视觉搜索和文本阅读两项任务中的眼动。有阅读障碍的参与者在阅读时更倾向于向右注视。他们在两个任务中同时处理的字母数量相同，而正常阅读者在阅读中处理的字母数量要多得多。重要的是，儿童的VA跨越能力与阅读中同时处理的字母数量有关。因此，一些阅读困难的读者在阅读时的非典型眼球运动似乎反映了根据任务要求增加他们的视觉广度的困难。(C) 2007 Elsevier Ltd.版权所有。
The eye movements of 14 French dyslexic children having a VA span reduction and 14 normal readers were compared in two tasks of visual search and text reading. The dyslexic participants made a higher number of rightward fixations in reading only. They simultaneously processed the same low number of letters in both tasks whereas normal readers processed far more letters in reading. Importantly, the children's VA span abilities related to the number of letters simultaneously processed in reading. The atypical eye movements of some dyslexic readers in reading thus appear to reflect difficulties to increase their VA span according to the task request. (C) 2007 Elsevier Ltd. All rights reserved.
