How does the number of features impact how people learn categories? In this work, we explore how the relationship between the number of features and the structure of categories influences learning in a category learning task. Experiments reported by Vong, Hendrickson, Navarro and Perfors (2019, Cognitive Science). The paper reports two experiments. Code and data are stored in the OSF repository.

• Experiment One (with timer)
• Experiment One (without timer)
• Experiment Two (with timer)
