EXTINCTION OF SENSORY PRECONDITIONING USING CER TRAINING

Gave 80 male hooded rats 16 sensory preconditioning (SPC) trials, with preconditioning stimuli presented in either forward or backward order. The SPC was followd by 0, 1, 4, 14, or 64 extinction trials and then CER training. The SPC, as indicated by suppression of consummatory drinking, occurred with forward but not backward conditioning. Amount of forward SPC was a decreasing function of the number of extinction trials. Results corresponded to comparable effects found in classical conditioning.
