Developmental dyslexia has been associated with a deficit in temporal processing, 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 dyslexia but suggest that limitations in auditory temporal processing might be compensated for by a well-functioning visual sensory modality.
发育性阅读障碍与时间加工缺陷有关，但假定的这种缺陷是全感官性的还是仅限于听觉通道仍存在争议。我们展示了诵读困难儿童听觉和视觉时间加工能力的心理物理学评估数据。虽然没有一个诵读困难儿童在视觉感官通道上表现出时间加工异常，但听觉时间得分较低的诵读困难儿童在视觉方面达到了高水平表现。我们的结果并未证实阅读障碍存在一般性时间加工缺陷的假设，而是表明听觉时间加工方面的局限可能会通过功能良好的视觉感官通道得到补偿。
