Enhanced consumption of an aversively conditioned taste following the presentation of a "medicine" taste.
Rats given presentations of a citric acid solution while recovering from LiCl-induced illness (i.e., a "medicine effect" treatment) subsequently drank more of an aversively conditioned NaCl solution at test, when the NaCl presentation was immediately preceded by citric acid. That is, citric acid passed a summation test of conditioned inhibition. Such an effect was not observed in a group given explicitly unpaired presentations of LiCl and citric acid. It is proposed that enhanced consumption of an aversive taste due to the previous presentation of a "medicine" taste can provide an animal model of human maladaptive behavior in regards to food consumption.
