视觉工作记忆能力与整体认知能力密切相关,可以在神经回路水平上理解,并且易于测量,因此引起了人们的极大兴趣。最近的研究表明,能力影响着从扫视目标到类比推理的各种任务。关于容量是否受到有限数量的离散表示或无限可分资源的限制,已经出现了争论,但经验证据和神经网络模型目前倾向于离散项目限制。个体和群体之间的记忆能力差异很大,最近的研究表明,其中一些差异反映了存储能力的真正差异,而另一些则反映了有效利用记忆能力的差异。
Visual working memory capacity is of great interest because it is strongly correlated with overall cognitive ability, can be understood at the level of neural circuits, and is easily measured. Recent studies have shown that capacity influences tasks ranging from saccade targeting to analogical reasoning. A debate has arisen over whether capacity is constrained by a limited number of discrete representations or by an infinitely divisible resource, but the empirical evidence and neural network models currently favor a discrete item limit. Capacity differs markedly across individuals and groups, and recent research indicates that some of these differences reflect true differences in storage capacity whereas others reflect variations in the ability to use memory capacity efficiently.
