Blocking Experiment

The effect of prior excitatory conditioning to a stimulus not included in the compound conditioning phase of the typical blocking experiment was assessed in three CER studies. The first experiment, in which rat subjects received A +, C +, or a combination of A + /C + trials prior to AB + conditioning, showed that A + /C + or C + training produced as robust blocking as A + training relative to a control group with no prior conditioning. A second experiment which was designed to assess the role of background cues in mediating the blocking effect indicated that background cues were not responsible for the A + or C + effects, while a third experiment showed these same effects were not mediated by stimulus generalization. The findings of these experiments are interpreted in the context of pseudoconditioning-induced rehearsal of a US representation in short-term memory.

Recent Developments

Recent developments in the study of stimulus generalization by means of operant conditioning methods require a re-examination of the problem of stimulus generalization and a review of the role of this concept in description and analysis of behavior. No final view of the outlines of learning theory can be achieved until more complete and fundamental information about generalization has been obtained. It has been established that in the pigeon orderly and reproducible bidirectional gradients can be obtained for individual Ss along the light-wavelength continuum. A dilemma is posed by the finding that these gradients are orderly on a physical scale; but not on an equal-discriminability scale. The form of the generalization function raises questions as the interpretation and meaning of the just-noticeable-difference concept. The problem of multidimensional stimulus generalization is discussed. The understanding of stimulus relationships in the generalization phenomenon is proposed as an issue of greater significance and difficulty than that of the control of generalization by such conventionally more prominent variables as drive and reinforcement.
