Reading is known to be primarily a linguistic task. However, to successfully decode written words, children also need to develop good visual-perception skills. Furthermore, motor skills are implicated in letter recognition and reading acquisition. Three studies have been designed to determine the link between reading, visual perception, and visual-motor integration using the Developmental Test of Visual Perception version 2 (DTVP-2). Study 1 tests how visual perception and visual-motor integration in kindergarten predict reading outcomes in Grade 1, in typical developing children. Study 2 is aimed at finding out if these skills can be seen as clinical markers in dyslexic children (DD). Study 3 determines if visual-motor integration and motor-reduced visual perception can distinguish DD children according to whether they exhibit or not developmental coordination disorder (DCD). Results showed that phonological awareness and visual-motor integration predicted reading outcomes one year later. DTVP-2 demonstrated similarities and differences in visual-motor integration and motor-reduced visual perception between children with DD, DCD, and both of these deficits. DTVP-2 is a suitable tool to investigate links between visual perception, visual-motor integration and reading, and to differentiate cognitive profiles of children with developmental disabilities (i.e. DD, DCD, and comorbid children).

众所周知，阅读主要是一项语言任务。然而，为了成功解码书面文字，儿童还需要培养良好的视觉感知技能。此外，运动技能与字母识别和阅读习得有关。已经设计了三项研究，使用视觉感知发展测试第二版（DTVP - 2）来确定阅读、视觉感知和视觉 - 运动整合之间的联系。研究1测试了幼儿园儿童的视觉感知和视觉 - 运动整合如何预测正常发育儿童一年级时的阅读成绩。研究2旨在查明这些技能是否可被视为阅读障碍儿童（DD）的临床指标。研究3确定视觉 - 运动整合和减少运动的视觉感知是否能根据是否患有发育协调障碍（DCD）来区分阅读障碍儿童。结果表明，语音意识和视觉 - 运动整合能预测一年后的阅读成绩。DTVP - 2显示了阅读障碍儿童、发育协调障碍儿童以及同时患有这两种缺陷的儿童在视觉 - 运动整合和减少运动的视觉感知方面的异同。DTVP - 2是一种合适的工具，可用于研究视觉感知、视觉 - 运动整合与阅读之间的联系，并区分发育障碍儿童（即阅读障碍儿童、发育协调障碍儿童和共病儿童）的认知特征。版权所有© 2017约翰·威利父子有限公司。
