Abstract:

Classical conditioning procedures were used to evaluate the development and extinction of conditioned HR changes in the albino rat. The data suggest that the experimental group a developed a generalized HR response to the apparatus, their HR remaining consistently and on Day 4 of conditioning, significantly above that of the control group during the 2 hr pre-conditioning period b showed an anticipatory HR increase during the CS presentation which was maximum after 4 to 6 sec of CS and was then followed by increases of less magnitude until just prior to and during the UCS period on non reinforced trials c demonstrated a localized conditioned HR response immediately post-UCS on non reinforced trials which appeared to reflect most adequately conditioned HR changes d showed signs of retention of conditioned HR responses on Day 5 and 30 of extinction.
