Abstract
Rats were given two-choice water-saccharin preference tests after saccharin had been paired with apomorphine hydrochloride for 1, 2, 4, 8, or 16 trials. The results indicated that the conditioned aversion is quite pronounced after only two trials and that suppression of single stimulus consumption of the CS substance during successive conditioning trials is not perfectly related to the preference data.
