视觉工作记忆（VWM）的容量是非常有限的。以往的研究表明，完形原则可以促进VWM的形成，但完形原则的类型、刺激的特征和实验设计的性质等因素是否会影响分组的有益效果仍存在争议。特别是，研究表明，感知分组可以提高与分组相关的特征的记忆性能，但不清楚是否存在与分组无关的特征的相同改善。本研究采用实证研究和元分析的方法，探讨知觉分组对视觉工作记忆的影响。在实证研究中，我们采用了Kanizsa错觉，其中的记忆项目被分组的错觉轮廓的分组效果进行了研究。我们发现，即使测试的功能是分组无关的分组项目的记忆性能得到改善，并改善是没有显着不同的效果分组的物理连通性或固体闭塞。在元分析研究中，我们通过从所有合格的研究中提取结果，系统地和定量地检验了知觉分组对VWM的影响，发现有益的分组效应是稳健的，但效果的大小可以受到几个调节因素的影响。分组方法的类型、记忆显示的持续时间和布局以及被试特征的特征等因素会调节分组效应，而是否采用线索或言语抑制任务则不会。我们的研究表明，潜在的机制的分组利益可能是不同的分组相关性的存储功能。对VWM的分组效应可以独立于对分组相关特征的注意，但是可以依赖于对分组不相关特征的注意优先化。
The capacity of visual working memory (VWM) is found to be extremely limited. Past research shows that VWM can be facilitated by Gestalt principles of grouping, however, it remains controversial whether factors like the type of Gestalt principles, the characteristics of stimuli and the nature of experimental design could affect the beneficial effect of grouping. In particular, studies have shown that perceptual grouping could improve memory performance for a feature that is relevant for grouping, but it is unclear whether the same improvement exists for a feature that is irrelevant for grouping. In this article, an empirical study and a meta-analytic study were conducted to investigate the effect of perceptual grouping on VWM. In the empirical study, we examined the grouping effect by employing a Kanizsa illusion in which memory items were grouped by illusory contour. We found that the memory performance was improved for the grouped items even though the tested feature was grouping irrelevant, and the improvement was not significantly different from the effect of grouping by physical connectedness or by solid occlusion. In the meta-analytic study, we systematically and quantitatively examined the effect of perceptual grouping on VWM by pulling the results from all eligible studies, and found that the beneficial grouping effect was robust but the magnitude of the effect can be affected by several moderators. Factors like the types of grouping methods, the duration and the layout of the memory display, and the characteristics of the tested feature moderated the grouping effect, whereas whether employing a cue or a verbal suppression task did not. Our study suggests that the underlying mechanism of the grouping benefit may be distinct with regard to grouping relevancy of the to-be-stored feature. The grouping effect on VWM may be independent of attention for a grouping relevant feature, but may rely on attentional prioritization for a grouping irrelevant feature.
