Comparisons have been suggested as central to category learning, yet we are only beginning to understand how different types of comparisons affect what people learn. Prior research has established that different ways of learning affect what information learners acquire, suggesting that different types of comparisons may also affect learning in different ways. An important comparison-type distinction in category learning is between-category versus within-category comparisons. The results of prior studies looking at these types of comparisons are mixed, so it remains unclear how each type of comparison affects category learning. This chapter lays out a framework based on the idea that the benefits of comparisons depend on both the type of comparison being made as well as what information needs to be learned. Specifically, between-category comparisons highlight distinguishing information between categories while within-category comparisons highlight commonalities and the relational structure of items.
