Conditioned heart rate changes lack meaningful hemodynamic effects; leaves open relevance to clinical stress reactivity in larger cohorts.
Does classical aversive conditioning alter hemodynamic variables in human subjects?
Conditioned heart rate changes during classical aversive conditioning in humans are too small to significantly alter other hemodynamic variables like stroke index or cardiac index.
Gliner et al. (1977) studied this question. Discriminative classical aversive conditioning was evaluated on Hemodynamic changes (heart rate, stroke index, cardiac index). Discriminative classical aversive conditioning induced heart rate decreases in 10 of 11 subjects, but these changes were too small to alter other hemodynamic variables.
