为了评估阅读障碍者和正常读者的同时视觉处理，使用了多元素处理任务，该任务需要报告简要呈现的多数字阵列中的单个数字。诵读困难的读者在 4 位和 6 位数字上表现出较高的识别阈值，但在 2 位数字阵列上则不然。多数字阵列上的个体识别阈值与阅读期间的眼球运动次数相关。阅读障碍的多元素处理缺陷并不伴有连贯运动检测缺陷或视觉优先检测缺陷，并且与语音意识和快速命名的缺陷无关。然而，只有大约一半的阅读困难读者表现出多元素处理缺陷。 (C) 2004 Elsevier Ltd. 保留所有权利。
For assessing simultaneous visual processing in dyslexic and normal readers a multi-element processing task was used which required the report of a single digit of briefly presented multi-digit arrays. Dyslexic readers exhibited higher recognition thresholds on 4- and 6-digit, but not on 2-digit arrays. Individual recognition thresholds on the multi-digit arrays were associated with number of eye movements during reading. The dyslexic multi-element processing deficit was not accompanied by deficient coherent motion detection or deficient visual precedence detection and was independent from deficits in phonological awareness and rapid naming. However, only about half of the dyslexic readers exhibited a multi-element processing deficit. (C) 2004 Elsevier Ltd. All rights reserved.
