Abstract

We challenge the central idea proposed in Hulleman & Olivers (H&O) by arguing that the “item” is still useful for understanding visual search and for developing new theoretical frameworks. The “item” is a flexible unit that represents not only an individual object, but also a bundle of objects that are grouped based on prior knowledge. Uncovering how the “item” is represented based on prior knowledge is essential for advancing theories of visual search.
