Abstract
Thirty three albino rats learned a successive B-W discrimination in Phase I and were then tested for induction in Phase II Both positive and negative induction-like effects appeared in Phase II, but no evidence for induction was found during Phase I discrimination training. The results were seen to be more nearly in line with a simple generalization decrement hypothesis rather than the classical Pavlovian induction hypothesis.
