title: Differential outcomes aid the formation of categorical relationships between stimuli.
abstract: The differential outcome effect is when learning is enhanced through the application of different outcomes to different conditions of a task. Here we explore whether one difference in learning with differential outcomes is an enhanced categorisation of objects. We demonstrate that participants learning conditional discriminations are better able to identify previously unpaired objects as belonging to the same category when differential outcomes were used in learning these stimuli.
