Abstract:

Five groups of six rats per group were tested daily for 60 days on two-bottle 30-min. preference test in which one bottle contained water and the second bottle contained either water or a 4, 8, 16, or 32 sucrose solution. A classically conditioned aversion was induced by pairing the taste of sucrose with an exposure to 100 R of X-rays 5 Rmin. on 3 successive occasions. The rate of sucrose drinking prior to, and following each irradiation, as well as the degree of the conditioned aversion, varied directly with the concentration of the sucrose solution. This was interpreted as evidence for the applicability to classical conditioning of Premacks reinforcement theory in which the rate of reinforced responding is determined in part by the precontingency rate of the response.
