Unifying Approaches to Understanding Capacity in Change Detection

Abstract

To navigate changes within a highly dynamic and complex environment, it is crucial to compare current visual representations of a scene to previously formed representations stored in memory. This process of mental comparison requires integrating information frommultiple sources to inform decisions about changeswithin the environment. In the present article, we combine a novel systems factorial technology change detection task (Blunden et al., 2022) with a set sizemanipulation. Participants were required to detect 0, 1, or 2 changes of low and high detectability between a memory and probe array of 1–4 spatially separated luminance discs. Analyses using systems factorial technology indicated t..
