Abstract: Categorization can have paradoxical effects on memory. According to a Bayesian model, it can cause memories to be biased while also causing them to be more accurate.  The rationality of categorization depends on how well the category mirrors the actual distribution of objects in the environment.  This talk will present evidence that categories are learned out of direct experience with objects, that they capture feature correlations within object distributions, and that they are used to adjust memories of individual objects in a rational Bayesian manner.
