大多数关于阅读障碍的研究都是在儿童中进行的，这引发了一个问题，即青少年阅读障碍的特征是否与成年阅读障碍的特征相似。本研究的目的是验证青少年阅读障碍者在阅读和阅读相关任务上的认知缺陷在成人阅读障碍者中是否相似。本研究测试了四年级阅读困难和正常阅读者两组，以及补偿阅读困难和正常阅读者两组学生。通过比较青少年阅读障碍者和对照组以及成年阅读障碍者与对照组在研究措施上的差异，可以清楚地看出，在成年组中，正常阅读者和阅读困难者在拼写任务上的差异明显较小，这种差异在成年人的语音任务中增加。这项研究的发现强化了这样的假设，即阅读障碍患者在语音-听觉通道上特别困难。另一个主要发现是语言和非语言任务的处理速度都很慢。可以假设，这些问题从很小的时候就开始出现，并在代偿性成人阅读障碍中持续存在。版权所有(C)2005 John Wiley&Sons，Ltd.
Most of the research into dyslexia has been carried out among children and has raised the question whether the characteristics of young dyslexics are similar to those of adult dyslexics. The aim of this research was, therefore, to confirm whether the cognitive deficits, which appear among young dyslexics on reading and reading related tasks, are similar among adult dyslexics.Four groups of subjects were tested in this study: two groups of fourth graders, dyslexic and normal readers, and two groups of students, compensated dyslexics and normal readers.A comparison of the differences in research measures between the young dyslexics and their control group, and between the adult dyslexics and their control group, clearly indicates that the difference between regular readers and dyslexics is significantly smaller in the adult group on orthographic tasks, and this difference increases in adults on phonological tasks.The findings of this study reinforce the assumption that dyslexics have particular difficulty with the phonological-auditory channel. Another main finding is the slow speed of processing in verbal and non-verbal tasks. It can be assumed that these problems start at a young age and persist in compensated adult dyslexics.
