“向后数字广度”（DSB）是临床神经心理学中最常用的评估工作记忆能力的测试。然而，目前尚不清楚这项任务是如何在认知上解决的。本研究旨在探讨视觉和语言认知策略在DSB中的应用。此外，基于同步存储和处理任务（Oberauer et al., 2003），研究了DSB与复杂跨任务之间的关系。在双任务条件下（r(PB) = .23），只有当相关数字以视觉方式呈现时，视觉化者的表现才比语言化者好。在所有条件下，DSB的表现与复杂跨度任务的相关性都很弱
The "digit span backwards" (DSB) is the most commonly used test in clinical neuropsychology to assess working memory capacity. Yet, it remains unclear how the task is solved cognitively. The present study was conducted to examine the use of visual and verbal cognitive strategies in the DSB. Further, the relationship between the DSB and a complex span task, based on the Simultaneous Storage and Processing task (Oberauer et al., 2003), was investigated. Visualizers performed better than verbalizers in the dual task condition (r(PB) = .23) only when the relevant digits were presented optically. Performance in the DSB correlated only weakly with the complex span task in all conditions (all tau
