S. Heim et al., Auditory temporal processing deficit in dyslexia is associated with enhanced sensitivity in the visual modality, NEUROREPORT, 12(3), 2001, pp. 507-510
Developmental dyslexia has been associated with a deficit in temporal proce
ssing, but it is controversial whether the postulated deficit is pansensory
or limited to the auditory modality. We present psychophysical assessment
data of auditory and visual temporal processing abilities in children with
dyslexia. While none of the dyslexic children displayed temporal processing
abnormalities in the visual sensory modality. dyslexics with poor auditory
temporal scores reached high-level visual performance. Our results do not
confirm the hypothesis of a general temporal processing deficit for dyslexi
a but suggest that limitations in auditory temporal processing might be com
pensated for by a well-functioning visual sensory modality. NeuroReport 12:
