Abstract
In Experiment I rats received 10 consecutive daily injections of either apomorphine hydrochloride or NaCl followed by 4 days of saccharin solution exposure paired with apomorphine or NaCl injections. Relative consumption of saccharin solution and water during conditioning indicated that preconditioning apomorphine UCS habituation retarded acquisition of a conditioned saccharin aversion. In Experiment II rats received 6 days of saccharin solution exposure paired with injections of either apomorphine hydrochloride or NaCl, then 10 daily injections of either apomorphine hydrochloride or NaCl, followed by 4 days of saccharin preference testing (no drug injections). Postconditioning apomorphine UCS habituation did not interfere with retention of saccharin aversion acquired in initial conditioning phase. These results showed that novelty of UCS is crucial in acquisition of but not retention of conditioned taste aversions.
