Research suggests that a central difficulty in dyslexia may be impaired rapid temporal processing. Good temporal processing is also needed for musical perception, which relies on the ability to detect rapid changes. Our study is the first to measure the perception of adults with and without dyslexia on all three dimensions of music (rhythm, pitch, and spectrum), as well as their capacity for auditory imagery and detection of slow changes, while controlling for working memory. Participants were undergraduate students, aged 20–35 years: 26 readers with dyslexia and 30 typical readers. Participants completed a battery of tests measuring aptitude for recognizing the similarity/difference in tone pitch or rhythm, spectral resolution, vividness/control of auditory imagination, the ability to detect slow changes in auditory stimuli, and working memory. As expected, readers with dyslexia showed poorer performance in pitch and rhythm than controls, but outperformed them in spectral perception. The data for each test was analyzed separately while controlling for the letter-number sequencing score. No differences between groups were found in slow-change detection or auditory imagery. Our results demonstrated that rapid temporal processing appears to be the main difficulty of readers with dyslexia, who demonstrated poorer performance when stimuli were presented quickly rather than slowly and better performance on a task when no temporal component was involved. These findings underscore the need for further study of temporal processing in readers with dyslexia. Remediation of temporal processing deficits may unmask the preserved or even superior abilities of people with dyslexia, leading to enhanced ability in all areas that utilize the temporal component.

阅读障碍者中与音乐相关的能力。

研究表明，诵读困难的中心困难可能是快速的颞叶处理受损。音乐感知还需要良好的时间处理，这取决于检测快速变化的能力。我们的研究是首次测量成年人在音乐的所有三个维度（节奏，音调和频谱）上是否患有诵读困难的知觉，以及他们在控制工作记忆的同时听觉图像和缓慢变化的检测能力。参加者是年龄在20-35岁之间的大学生：26位阅读障碍的读者和30位典型的读者。参加者完成了一系列测试，这些测试测量了用于识别音调或节奏的相似性/差异，频谱分辨率，听觉想象力的生动性/控制力，检测听觉刺激的缓慢变化的能力以及工作记忆的能力。正如预期的那样，患有阅读障碍的读者在音调和节奏上的表现比对照组差，但在频谱感知方面却胜过他们。在控制字母数字顺序得分的同时，分别分析了每个测试的数据。在慢变化检测或听觉图像中未发现组之间的差异。我们的结果表明快速的时态处理似乎是阅读障碍的读者的主要困难，当快速地而不是缓慢地施加刺激时，他们表现出较差的表现，而在没有涉及时间的情况下，表现出更好的任务表现。这些发现强调需要对阅读障碍的读者进行时间加工的进一步研究。暂时性处理缺陷的补救措施可能会掩盖阅读障碍者的能力甚至保持其较高水平，从而导致在利用颞部成分的所有领域中的能力得​​到增强。
