Colour discrimination difficulties
Colour vision deficiencies are important because they can be a contributory factor in learning difficulties. Although they are not treatable, teachers and parents can help students adjust to this condition. Learning activities in the classroom must be adapted to allow for any colour vision problems detected in the student. In rare cases, dyslexic students can suffer from colour anomia – i.e. a neurological deficit which affects the extent and speed with which they are able to name colours. About 10% of dyslexic students have been reported to have this difficulty, which appears to be connected with visual and verbal memory in some way (Mattocks and Hynd, 1986).
