Predictability and number of pairings in Pavlovian fear conditioning

  • Robert A. Rescorla
Animal Behavior Avoidance and Punishment

Abstract

Three groups of dogs were Sidman avoidance trained. They then received different kinds of Pavlovian fear conditioning. For one group CSs and USs occurred randomly and independently; for a second group, CSs predicted the occurrence of USs; for a third group, CSs predicted the absence of the USs. The CSs were subsequently presented while S performed the avoidance response. CSs which had predicted the occurrence or the absence of USs produced, respectively, increases and decreases in avoidance rate. For the group with random CSs and USs in conditioning, the CS had no effect upon avoidance.
