Abstract

Despite the adaptative nature of working memory (WM) refinement (e.g. repulsion), a fundamental question remains unaddressed: what constitutes the unit of WM refinement? Specifically, does the refinement process apply to the entire object (object-based), specific features (feature-based), or potentially involve other mechanisms? Utilizing dual-feature objects and the continuous memory task, we examined whether the repulsion distortion induced in one feature (the trigger feature) could be transmitted to other features (the dependent feature) of the same object. Across one preliminary experiment and five formal experiments, we supported that the WM refinement is neither strictly object-based nor feature-based, but occurs dynamically and sequentially across distinct features. Specifically, the repulsion induced by the trigger feature was transmitted to the dependent feature only during extended maintenance periods, not during short maintenance. Our findings supported the dynamic sequential refinement of WM: refinement induced by a trigger feature could extend to other features, but this transmission is time-consuming.

特征的多米诺骨牌：工作记忆表征的动态顺序细化

尽管工作记忆（WM）细化具有适应性（如排斥），但一个基本问题仍未得到解决：WM细化的单位是什么？具体来说，精化过程是应用于整个对象（基于对象）、特定的特性（基于特性），还是潜在地涉及其他机制？利用双特征对象和连续记忆任务，我们研究了在一个特征（触发特征）中引起的排斥扭曲是否可以传递到同一对象的其他特征（依赖特征）。通过一个初步实验和五个正式实验，我们支持WM的细化既不是严格基于对象的，也不是基于特征的，而是动态地、顺序地跨不同的特征进行的。具体地说，触发特征引起的斥力只在延长的维护期间传递给依赖特征，而不是在短暂的维护期间。我们的发现支持WM的动态顺序细化：由触发特征引起的细化可以扩展到其他特征，但这种传递是耗时的。

期刊介绍： Cognition is an international journal that publishes theoretical and experimental papers on the study of the mind. It covers a wide variety of subjects concerning all the different aspects of cognition, ranging from biological and experimental studies to formal analysis. Contributions from the fields of psychology, neuroscience, linguistics, computer science, mathematics, ethology and philosophy are welcome in this journal provided that they have some bearing on the functioning of the mind. In addition, the journal serves as a forum for discussion of social and political aspects of cognitive science.
