Abstract
Generalization of an instrumental response in the rat to stimuli varying in the size dimension was investigated under 12 and 48 hr. of food deprivation. Generalization gradients for the 48-hr. condition were higher and of steeper slope than those for 12 hr. The data conform rather precisely to the implications of a multiplicative theory of habit and drive. The group means of 2 response measures, speed of the 1st test response, and number of extinction responses to the test stimuli, were linearly related with a correlation of .99. Implications of such findings for a reaction-potential concept are discussed.Keywords
