人类如何能够在记忆中保持视觉项目的详细表征？当需要进行精细区分时，我们有时会隐式地将记忆表征彼此区分开来，以减少项目间的混淆。然而，这种表征的分离可能会在不经意间导致记忆被回忆时偏离其他记忆项目，这种现象被称为排斥偏见。使用非视网膜特异性工作记忆范式，我们发现更强的排斥偏见与更长的工作记忆延迟，但只有当项目积极维持。这些结果表明：(1)排斥偏向可以反映一种助记现象，不同于知觉驱动的排斥偏向观察；(2)助记排斥偏向在维持过程中持续存在，依赖于对内部维持记忆项目的注意。这些结果支持了工作记忆项目相互依赖表征的理论，并进一步揭示了在维持过程中对工作记忆项目的强烈关注会增加它们之间的排斥偏差的背景。
How are humans capable of maintaining detailed representations of visual items in memory? When required to make fine discriminations, we sometimes implicitly differentiate memory representations away from each other to reduce inter-item confusion. However, this separation of representations can inadvertently lead memories to be recalled as biased away from other memory items, a phenomenon termed repulsion bias. Using a non-retinotopically specific working memory paradigm, we found stronger repulsion bias with longer working memory delays, but only when items were actively maintained. These results suggest that (1) repulsion bias can reflect a mnemonic phenomenon, distinct from perceptually driven observations of repulsion bias, and (2) mnemonic repulsion bias is ongoing during maintenance and dependent on attention to internally maintained memory items. These results support theories of working memory where items are represented interdependently and further reveals contexts where stronger attention to working memory items during maintenance increases repulsion bias between them.
