The role of perceptual similarities in determining the asymmetric mixed-category advantage.

What is it about?

Our visual environment is a diverse collection of stimuli sourced from various categories. Research has shown that memory performance is better when different categories of stimuli are combined, rather than when a single category is presented. However, recent studies have revealed that not all combinations of stimuli produce comparable memory enhancement, which has resulted in an unresolved asymmetry in the mixed-category advantage. Our findings, in contrast to previous interpretations that primarily rely on high-level cognitive processing, demonstrate that low-level encoding processes also impact memory enhancement. Specifically, our study provides evidence that the perceptual similarities between stimuli derived from different categories have an effect on the extent of the mixed-category advantage.
