A crucial role for working memory in temporary information processing and guidance of complex behavior has been recognized for many decades. There is emerging consensus that working-memory maintenance results from the interactions among long-term memory representations and basic processes, including attention, that are instantiated as reentrant loops between frontal and posterior cortical areas, as well as sub-cortical structures. The nature of such interactions can account for capacity limitations, lifespan changes, and restricted transfer after working-memory training. Recent data and models indicate that working memory may also be based on synaptic plasticity and that working memory can operate on non-consciously perceived information.
数十年来，人们已经认识到工作记忆在临时信息处理和复杂行为引导中起着至关重要的作用。越来越多的共识认为，工作记忆的维持源于长期记忆表征与包括注意力在内的基本过程之间的相互作用，这些过程表现为额叶和后皮质区域以及皮质下结构之间的折返环路。这种相互作用的性质可以解释容量限制、寿命变化以及工作记忆训练后的有限迁移。最近的数据和模型表明，工作记忆也可能基于突触可塑性，并且工作记忆可以对无意识感知的信息进行操作。
