Previous studies showed that rats preferred and also ran faster for multiple pellets than a single pellet of food. Here, we manipulated the rewarding effects of surface area occupied by food pellets on preference and running speed of rats trained on a T-maze. Twenty-two male adult Sprague-Dawley rats were trained to prefer one T-maze arm containing 30 food pellets scattered and the other arm with 30 pellets clustered. There was a significant preference for clustered food pieces over the scattered ones.
