![]() ![]() As such, it supports most cognitive tasks but it is limited in capacity. Visual working memory (VWM) allows us to temporarily store and process relevant information from the visual world across temporary interruptions such as saccades. Thus, the Gestalt principle of similarity benefits visual perception, but it can provide benefits to VWM as well. In short, the VWM performance benefit derived from similarity was constrained by spatial proximity such that similar items need to be near each other. Experiment 2 replicated and extended this finding by showing that similarity was only effective when the similar stimuli were proximal. Experiment 1 established the basic finding that VWM performance could benefit from grouping. Here, we investigated whether grouping by similarity benefits VWM. One prevalent Gestalt principle, similarity, has not been examined with regard to facilitating VWM. ![]() This introduces the question: do these perceptual benefits extend to VWM? If so, can this be an approach to enhance VWM function by optimizing the processing of information? Previous findings demonstrate that several Gestalt principles (connectedness, common region, and spatial proximity) do facilitate VWM performance in change detection tasks ( Woodman, Vecera, & Luck, 2003 Xu, 2002a, 2006 Xu & Chun, 2007 Jiang, Olson & Chun, 2000). Visual perception processing is facilitated by Gestalt principles of grouping, such as connectedness, similarity, and proximity. Visual working memory (VWM) is essential for many cognitive processes yet it is notably limited in capacity. ![]()
