Abstract

Taste aversion conditioning is a uniquely learned behavior. In most laboratory cases, the subjects receive a dose of the drug in question and a bottle of saccharin (sacc). Ordinarily, rats will strongly prefer drinking sacc to water (Fig. 1). Whereas with taste aversion, rats develop an aversion to the sacc and choose to mainly drink water instead. If the rat avoids the water as well as the sacc, the dosage is probably so strong that the rat loses motivation to drink anything. The actual reason for taste aversion is not known. Garcia and Koelling (1966) have suggested that aversion is caused by “agents which produce nausea and gastric upset”.1 Others point out that psychoactive drugs are capable of producing conditioning responses in the absence of any signs of toxicity.2 There are many other hypotheses for why taste aversion happens.
