Abstract
This experiment tests the effects of rewarding all three positions, or only the left and right positions, in three-stimuli oddity problems. After pretraining, Ss were assigned either to a simple oddity problem or to a dimension-abstracted oddity problem, with their nonpreferred dimension being variable and irrelevant. Rewarding all three positions in an array significantly improved performance on problems containing variable irrelevant dimensions. On simple problems, no differences due to reward positioning were found.
