The aim of the present study was to examine the effects of colored filters on reading performance and eye movement control in children with and without dyslexia.
Eighteen children with dyslexia and 18 children without dyslexia were seated on a chair with their heads stabilized by a forehead and chin support. The children read different texts under the following three filter conditions: no filter, yellow filter, and green filter. The children's eye movements were recorded with a Mobile EyeBrain Tracker. Reading total time, duration of fixation between two successive saccades, pro-saccades amplitude and number of pro- and retro-saccades were obtained.
Children with dyslexia read the fastest and had the shortest fixation time in the green filter condition compared with the other conditions. Furthermore, children with dyslexia showed the shortest fixation time in the green filter condition with respect to the other conditions.
Taken together, these results suggested that the green filter improved reading performance in children with dyslexia because the filter most likely facilitated cortical activity and decreased visual distortions.
本研究旨在探讨有色滤光片对伴或不伴阅读障碍儿童阅读表现和眼球运动控制的影响。
18 名阅读障碍儿童和 18 名非阅读障碍儿童坐在带额托和颏托的椅子上，头部固定。儿童在以下三种滤光片条件下阅读不同的文本：无滤光片、黄色滤光片和绿色滤光片。使用 Mobile EyeBrain Tracker 记录儿童的眼球运动。获得阅读总时间、两个连续眼跳之间注视时间、前向眼跳幅度和前向、后向眼跳数量。
与其他条件相比，阅读障碍儿童在绿色滤光片条件下阅读速度最快，注视时间最短。此外，阅读障碍儿童在绿色滤光片条件下的注视时间最短。
综上所述，这些结果表明绿色滤光片改善了阅读障碍儿童的阅读表现，因为滤光片可能促进了皮质活动并减少了视觉扭曲。
