In class we replicated the McDaniels et al. (2014) Builders and Diggers category learning experiment. Half of the class learned to categorize Builder and Digger animals using a simple rule, while the other half focused on perceptual similarities. At test, new animals of two types were presented: good transfer items and bad transfer items. Good transfer items were perceptually similar to the category for whom the rule applied. Bad transfer items met the rule for belonging to one category, but were more perceptually similar to the other category. What was the pattern of reuslts in this experiment?
