To investigate the effects of spectral overlays on reading performance of Brazilian elementary school children.
Sixty-eight children (aged 9-12 years) enrolled in the 5th and 6th grade were included in the study. The Rate of Reading Test (RRT - Brazilian Portuguese version) was used to evaluate reading speed and the Irlen Reading Perceptual Scale was used to allocate the sample according to reading difficulty/discomfort symptoms and to define the optimal spectral overlays.
A total of 13% of the children presented an improvement of at least 15% in reading speed with the use of spectral overlays. Pupils with severe reading difficulties tended to have more improvement in RRT with spectral overlays. Children with severe reading discomfort obtained the highest gains in RRT, with an average of 9.6% improvement with intervention, compared to a decrease of -8.2% in the control group. Participants with severe discomfort had an odds ratio of 3.36 to improve reading speed with intervention compared to the control group.
The use of spectral overlays can improve reading performance, particularly in those children with severe visual discomfort.
探讨光谱叠加对巴西小学生阅读能力的影响。
本研究纳入了68名五、六年级的儿童（年龄9 - 12岁）。使用阅读速度测试（RRT - 巴西葡萄牙语版）评估阅读速度，并使用伊尔伦阅读感知量表根据阅读困难/不适症状对样本进行分组，并确定最佳光谱叠加。
共有13%的儿童在使用光谱叠加后阅读速度提高了至少15%。阅读困难严重的学生在使用光谱叠加后阅读速度测试（RRT）的改善往往更大。阅读不适严重的儿童在RRT中获得的提高最大，干预后平均提高9.6%，而对照组下降了-8.2%。与对照组相比，严重不适的参与者通过干预提高阅读速度的优势比为3.36。
使用光谱叠加可以提高阅读能力，特别是对于那些有严重视觉不适的儿童。
