Abstract
Two studies using partial or consistent large (500 mg) and small (45 mg) reward are presented. In both studies, after extended reward acquisition, differences are negligible or nonexistent. Results from the partial reward groups indicate extinction differences also disappear after extended training. These results do not seem to be in line with usual assumptions regarding the effects of reward magnitude.
