The potential role of visual processing deficits in reading difficulty was brought to public attention by claims that a large proportion of children with dyslexia suffer from a perceptual dysfunction currently referred to as Meares-Irlen syndrome (MISViS). A previous study showing that visual perceptual measures involving visual memory and discrimination predict independent variance in reading achievement [J. Learn. Disabil. 28 (1995) 216] provides a basis to examine their relationships with the diagnostic criteria of MISViS. This study examined these visual processing characteristics in 36 eight- to ten-year-old children, half of whom were experiencing reading difficulty. Children were assessed for MISViS by Irlen screeners; approximately half of the participants in each group were positively identified. Concurrent performance on standardized visual processing tests showed that while a positive diagnosis of MISViS is not indicative of reading ability, nor in particular of a visual-processing deficit subtype identified by Watson and Willows [J. Learn. Disabil. 28 (1995) 216], MISViS can indicate visual processing difficulties potentially related to visual attention inefficiency.
很大一部分诵读困难儿童患有目前被称为米尔斯 - 厄伦综合征（MISViS）的感知功能障碍。先前一项研究表明，涉及视觉记忆和辨别的视觉感知测量能够预测阅读成绩中的独立差异[《学习障碍杂志》28（1995年）216页]，这为研究它们与MISViS诊断标准之间的关系提供了依据。本研究调查了36名8至10岁儿童的这些视觉处理特征，其中一半儿童存在阅读困难。通过厄伦筛查工具对儿童进行MISViS评估；每组中约一半参与者被确诊。标准化视觉处理测试的同时表现表明，虽然MISViS的阳性诊断并不表明阅读能力，尤其不能表明由沃森和威洛斯[《学习障碍杂志》28（1995年）216页]所确定的视觉处理缺陷亚型，但MISViS可表明可能与视觉注意力低效相关的视觉处理困难。
