A Novel Procedure for Evaluating the Reinforcing Properties of Tastants in Laboratory Rats: Operant Intraoral Self-administration AnneMarie Levy1, Cheryl L. Limebeer1, Justin Ferdinand1, Ucal Shillingford1, Linda A. Parker1, Francesco Leri1 1Department of Psychology, University of Guelph The current study evaluates a novel procedure for assessing the reinforcing effects of palatable solutions in laboratory rats: intraoral self-administration.
