ABSTRACT: This study examined the differences in processing between typical and
dyslexic readers in a lexical decision task in different modalities (visual,
auditory, and cross modality). In general, dyslexics exhibited slower reaction times and made more
mistakes when performing the task. The biggest gap between the two groups of
readers was found on the visual task. However, the dyslexics benefited from the
cross modality presentation, with differences between the two groups minimized.
The results of this study indicate that the slowness characteristic of
dyslexics’ stems mainly from slow processing of visual linguistic information
and that supporting both processing systems relevant to reading will assist
inter-sensory integration and may ease the word decoding process among
dyslexics.
