Question

Quizplus · Accepted Answer

Garcia and colleagues accidentally discovered taste aversion when they studied the effects of radiation on rats. They found that the rats who consumed a novel-tasting substance before being exposed to radiation would later avoid the substance. This learning occurred quickly and without the need for repeated pairings, which is a characteristic of classical conditioning with taste as the conditioned stimulus. Thus, the correct answer is D, taste aversion. Anticipatory nausea and taste perception are not related to the accidental discovery of taste aversion. While a variant of classical conditioning could be argued as an answer, the accidental discovery was specifically the formation of a taste aversion without repeated pairings, which is not necessarily a common feature of classical conditioning.
