David Donner (Leatherhead, Surrey) contributes his views to the recent debate on dyslexia in the letters pages of Optician
For instance, Hutzler et al1 (2006) investigated eye movements by showing dyslexics and control groups of consonants, such as DSB, LQWB and VPLL. The subjects had to say whether each group of consonants had a double letter in them or not. This meant that the subjects had to look at each 'word' in a similar manner to reading, but no higher skills of language and sound recognition were required. No differences in the eye movement patterns between dyslexics and non-dyslexics were found.
