人们越来越有兴趣使用 Cogmed-RM 等适应性训练干预措施来提高工作记忆 (WM) 的容量，但这种干预措施的设计可能并非最佳。例如，Cogmed-RM 可以针对 WM 容量的主内存 (PM) 组件，但不能针对辅助内存 (SM) 组件。本研究假设 Cogmed-RM 不针对 SM 能力，因为它使用的简单跨度练习可能不会导致训练期间 PM 丢失足够量的信息。为了进行调查，我们将参与者随机分配到标准（简单范围；N = 31）或修改后（复杂范围；N = 30）训练条件。主要发现表明，即使在改进的训练条件下，SM 能力也没有提高。因此，基于跨度的 WM 干预措施的效力不能简单地通过将简单的跨度练习转换为复杂的跨度练习来增加。 (C) 2012 年记忆和认知应用研究学会。由爱思唯尔公司出版。保留所有权利。
There has been growing interest in using adaptive training interventions such as Cogmed-RM to increase the capacity of working memory (WM), but this intervention may not be optimally designed. For instance, Cogmed-RM can target the primary memory (PM) component of WM capacity, but not the secondary memory (SM) component. The present study hypothesized that Cogmed-RM does not target SM capacity because the simple span exercises it uses may not cause a sufficient amount of information to be lost from PM during training. To investigate, we randomly assigned participants to either a standard (simple span; N = 31) or a modified (complex span; N = 30) training condition. The main findings showed that SM capacity did not improve, even in the modified training condition. Hence, the potency of span-based WM interventions cannot be increased simply by converting simple span exercises into complex span exercises.
