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. However, 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 have demonstrated that several Gestalt principles (connectedness, common region, and spatial proximity) do facilitate VWM performance in change detection tasks (Jiang, Olson, & Chun, 2000 Woodman, Vecera, & Luck, 2003 Xu, 2002, 2006 Xu & Chun, 2007). Visual perception processing is facilitated by Gestalt principles of grouping, such as connectedness, similarity, and proximity. Organization: The second stage of the perceptual process the process through which we mentally arrange information into meaningful and digestible patterns.Visual working memory (VWM) is essential for many cognitive processes, yet it is notably limited in capacity. Gestalt Laws of Grouping: A set of principles in psychology that explains how humans naturally perceive stimuli as organized patterns and objects.
