Abstract:
Two groups of pigeons, one given high shock and the other low shock, were trained to peck at a key for food reinforcement. Responses were reinforced in the presence of a tone and extinguished in its absence. Following training, Ss were given the opposite shock intensity and tested for generalization under conditions of extinction to a series of seven auditory stimuli varying in intensity. The predicted drive-stimulus interaction effect seems to occur only briefly after a drive shift. An analysis of the gradients in terms of successive trial blocks showed that the generalization curves, regardless of the direction of the shift in shock level, tended to shift past SD away from Sdelta. This tendency increased as a function of the extinction process. Several alternative explanations for these effects are discussed but the data do not allow the establishment of the validity of one explanation over another. Author
