STUDIES OF CLASSICAL HEART RATE CONDITIONING IN THE RAT,

Abstract

Four rat heart rate conditioning studies are presented. Measures were (1) HR changes during 8 sec. CS 9550 cps tone) and (2) immediately after the CS when the UCS (0.5 sec. shock) was not presented. Using analysis of variance, significant evidence of conditioning was found. The CR was a cardiac deceleration on early trials each day, followed by a cardiac accelera tion on later trials. The orienting response to tone was found to show similar changes as a function of trials. It was concluded that pre vous investigators would have also observed conditioned acceleration had they given a larger number of conditioning trials. The data were viewed as consistent with a stimulus substitu tion theory of conditioning, although other hypotheses were not ruled out. (Author)
