摘要

确定工作记忆的操作单元是理解工作记忆如何发挥作用的基本问题之一。认知研究中流行的基于对象的理论预测,记忆操作是在对象的层面上进行的。在这里,我们证明了工作记忆操作的基本单位是布尔图,这是一种描述瞬间可感知事物的数据结构。我们开发了四种新的操作任务(数据来自 80 名成人),结果表明,只有当操作的布尔图数量增加时,操作时间才会增加。增加操作方向的数量并不会导致操作时间的延长,这与布尔图理论的一个关键预测是一致的。我们的研究结果表明,布尔图是工作记忆的操作单元。

The Basic Units of Working Memory Manipulation Are Boolean Maps, Not Objects.

Determining the manipulation unit of working memory is one of the fundamental questions in understanding how working memory functions. The prevalent object-based theory in cognitive research predicts that memory manipulation is performed on the level of objects. Here we show instead that the basic units of working memory manipulation are Boolean maps, a data structure describing what can be perceived in an instant. We developed four new manipulation tasks (with data from 80 adults) and showed that manipulation times only increased when the number of Boolean maps manipulated increased. Increasing the number of orientations manipulated did not induce longer manipulation times, consistent with a key prediction of the Boolean map theory. Our results show that Boolean maps are the manipulation unit of working memory.
