Abstract | Background Coloured overlay and extra-large letter spacing may improve reading speed and accuracy in individuals with dyslexia; however, research has yet to identify which types of reading errors are diminished. Aim To determine the impact of extra-large letter spacing and colour overlay on reading and assess the impact of both interventions on reading errors. Sample Thirty-two dyslexic children were matched on age, verbal and non-verbal IQ with 27 children with no diagnosis of dyslexia. The average age of each group was 13 years. Method Participants read four texts with either standard or extra-large letter spacing with or without a coloured overlay. Results Extra-large letter spacing significantly improved reading speed more substantially for the dyslexia group. In addition, extra-large letters significantly reduced the number of missed word errors made by the dyslexia group. In contrast, coloured overlays did not significantly impact reading speed or the reduction of errors. Conclusion Increasing letter spacing is an effective way for teachers to improve reading skills in students with dyslexia. |
