Stimulus generalization as a function of level of motivation.

Abstract

Employed the key-pecking response in the pigeon to study stimulus generalization as a function of level of hunger. Response strength appeared to be negatively accelerated increasing function of weight loss. In addition, the slope of the gradient varies with the drive level at time of test but independent of drive level during training. Results question any position which views response strength as a single entity, to be considered independent of its associational and motivational components.
