Abstract

Examined heart-rate (HR) classical conditioning, shuttle-box training, and bar-press self-stimulation in male albino rabbits in 3 experiments as a function of 3 intensities of electrical stimulation of the septal region. In the HR classical conditioning experiment (n = 24), CRs failed to occur in a low-intensity group even though reliable UCRs were elicited. In 2 higher intensity groups HR CRs were decelerative. 12 Ss from Exp. 1 made approach responses to the lowest UCS intensity, but escape responses to higher intensities when tested in the shuttle box. In the self-stimulation experiment, 8 naive Ss bar pressed at all 3 intensities. At the 2 highest values, bar pressing was accompanied by attempted escape responses. It is concluded that HR classical conditioning to septal stimulation requires an aversive component to the UCS. (35 ref.) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
