摘要
我们沉浸在持续不断的信息流中,这迫使我们的认知系统在必要的处理时间内保持相关元素的可访问性。本研究调查了工作记忆如何在面对繁重的处理过程时平衡这种必要存储的资源需求。在四项使用复杂跨度任务的实验中,我们考察了在另一个部分表现最佳的人在记忆和处理过程中的剩余表现。互惠的双任务成本表明这两种功能之间存在资源共享。然而,优先处理任务几乎取消了参与者的记忆表现,而在保持跨度记忆表现的同时,却保留了超过 60% 的处理能力。我们认为,这种不对称性在本质上可能是适应性的。工作记忆可能是作为一个以行动为导向的系统进化而来的,在这个系统中,短时记忆容量在结构上是有限的,以便腾出处理所保存信息所需的资源。(PsycInfo Database Record (c) 2024 APA, all rights reserved)。
Human cognitive system privileges processing over short-term storage: Asymmetry in working memory limitations.
The continuous flow of information in which we are immersed obliges our cognitive system to maintain accessible the relevant elements for the time necessary for their processing. The present study investigated how working memory balances the resource demands of this necessary storage in the face of demanding processing. In four experiments using a complex span task, we examined the residual performance in memory and processing of individuals who performed at their best in the other component. Reciprocal dual-task costs pointed toward a resource sharing between the two functions. However, whereas prioritizing processing almost abolished participants' memory performance, more than 60% of their processing capacities were preserved while maintaining memory performance at span. We argue that this asymmetry might be adaptive in nature. Working memory might have evolved as an action-oriented system in which short-term memory capacity is structurally limited to spare the resources needed for processing the information it holds.
