基于工作记忆与错误检测的关系，本研究探讨了训练对阅读障碍者工作记忆的影响，以及训练对阅读障碍者错误检测机制的影响。27名阅读障碍者和34名对照者，都是大学生，参加了这项研究。ERP方法和行为措施，采用之前，之后立即，6个月后的培训。CogniFit个人教练计划，其中包括24个会议的直接训练的工作记忆技能，被使用。两组读者都从培训计划中获益，但阅读障碍读者的获益明显更多。在阅读障碍组，数字广度从9.84±3.15增加到10.79±3.03。工作记忆训练使每分钟正确阅读的单词数显著增加了14.73%。成年人的大脑活动改变了训练的结果，证明了工作记忆容量和错误相关负波（ERN）组件（24.71%）的幅度增加。当ERN振幅增加时，斯滕贝格测试的错误百分比降低。我们认为，通过扩大工作记忆容量，更大的信息单位保留在系统中，使更有效的错误检测。中央执行作为工作记忆的一个子组件的重要功能也进行了讨论。
Based on the relationship between working memory and error detection, we investigated the capacity of adult dyslexic readers' working memory to change as a result of training, and the impact of training on the error detection mechanism. 27 dyslexics and 34 controls, all university students, participated in the study. ERP methodology and behavioral measures were employed prior to, immediately after, and 6 months after training. The CogniFit Personal Coach Program, which consists of 24 sessions of direct training of working memory skills, was used. Both groups of readers gained from the training program but the dyslexic readers gained significantly more. In the dyslexic group, digit span increased from 9.84±3.15 to 10.79±3.03. Working memory training significantly increased the number of words per minute read correctly by 14.73%. Adult brain activity changed as a result of training, evidenced by an increase in both working memory capacity and the amplitude of the Error-related Negativity (ERN) component (24.71%). When ERN amplitudes increased, the percentage of errors on the Sternberg tests decreased. We suggest that by expanding the working memory capacity, larger units of information are retained in the system, enabling more effective error detection. The crucial functioning of the central-executive as a sub-component of the working memory is also discussed.
