节奏听觉串行添加任务（PASAT）对工作记忆缺陷的敏感性可以通过检查“二元组”（即，正确反应之前紧接着正确反应）作为传统正确总分的补充来增强。在 397 名主要是非洲裔美国人 (79%) 健康成年人的样本中，总二元分数和总正确分数高度相关 (r =.96，p <.001)；然而，这种关联的程度在更快的刺激呈现试验中减弱，特别是在工作记忆能力受损的参与者中。
The sensitivity of the Paced Auditory Serial Addition Task (PASAT) to working memory deficits may be enhanced by examining "dyads" (i.e., correct responses immediately preceded by a correct response) as a complement to the traditional total correct summary score. In a sample of 397 mostly Aftican American (79%) healthy adults, total dyad and total correct scores were highly correlated (r =.96, p < .001); however the magnitude of this association diminished in faster stimulus presentation trials, particularly among participants with impaired working memory abilities.
