多发性硬化症(MS)患者在信息处理过程中经常经历认知障碍。然而，加工速度能力和工作记忆能力对信息加工任务的相对贡献还没有被完全理解。目前的研究考察了处理速度和/或工作记忆能力对信息处理任务--跟踪任务(KTT)的影响程度。49名多发性硬化症患者接受了测试，以评估处理速度和工作记忆，以及KTT。回归分析表明，在MS组中，处理速度能力解释了KTT成绩的大部分解释差异。研究结果表明，加工速度对多发性硬化症患者的KTT表现有显著影响，并讨论了提高多发性硬化症患者加工速度能力的认知康复治疗的意义。
Individuals with multiple sclerosis (MS) often experience cognitive impairments in information processing. However, the relative contributions of processing speed abilities and working memory abilities to information-processing tasks are not yet fully understood. The current study examined the extent to which processing speed and/or working memory abilities contributed to an information-processing task, the Keeping Track Task (KTT). Forty-nine individuals with MS were given tests to assess processing speed and working memory, as well as the KTT. Regression analyses indicated that in the MS group, processing speed abilities accounted for the majority of the explained variance in KTT performance. The findings suggest that processing speed plays a significant role on KTT performance in MS. Implications for cognitive rehabilitation treatments aimed at improving processing speed abilities in MS are discussed.
