The Paced Auditory Serial Addition Task (PASAT) is a cognitive task purported to measure working memory, speed of information processing, and sustained and divided attention (Spreen, O. & Strauss, E. (1998). A compendium of neuropsychological tests: administration, norms, and commentary (2nd ed.). New York, NY: Oxford University Press.) The current study examined whether treating late responses on the PASAT as correct or as incorrect can significantly affect the outcome of the test in individuals with Multiple Sclerosis (MS). Subjects consisted of 59 individuals with MS and 37 healthy controls (HC). Scoring method was found to affect the number of individuals who were considered impaired on the PASAT. When participants were penalized for late responses significantly more participants, in both groups, were found to be impaired on the 2s trial of the task (MS: p<0.01; HC: p<0.05). Results indicate that that the specific scoring of the PASAT should be reported in studies that use the test.
听觉序列加法任务（PASAT）是一项认知任务，旨在测量工作记忆、信息处理速度以及持续性和分散性注意力（斯普林，O. & 施特劳斯，E.（1998年）。神经心理学测试纲要：施测、常模及评论（第2版）。纽约，纽约州：牛津大学出版社。）本研究考察了在多发性硬化症（MS）患者中，将PASAT中的延迟反应视为正确或错误是否会显著影响测试结果。研究对象包括59名MS患者和37名健康对照者（HC）。结果发现，评分方法会影响在PASAT测试中被判定为受损的个体数量。当参与者因延迟反应而受到惩罚时，两组中在任务的2秒试验中被发现受损的参与者明显更多（MS组：p<0.01；HC组：p<0.05）。结果表明，在使用该测试的研究中应报告PASAT的具体评分方法。
