HEART RATE CONDITIONING IN THE RAT,
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.
