“…This process, called categorization, is a basic mental process in cognition, and without it the world would appear chaotic (Bueno & Megherbi, 2009).

In Experiment 2, we adopted an exemplar generation task and identified four alternative measures to describe the strength of the relationship between a given category and its exemplars: exemplar generation dominance, mean rank order, first occurrence, and exemplar availability.…”
