Cardiac-Metabolic Dissociation: Additional Heart Rates during Psychological Stress
The main focus of this chapter is on basic experimental research conducted to demonstrate that the large cardiac increases displayed by certain individuals during psychological stress are indeed over and above the adjustments dictated by the physical, or metabolic, demands of the situation. However, in addition to examining this cardiac-metabolic dissociation, the chapter provides a good opportunity to illustrate several of the points discussed in earlier chapters with examples from actual experiments. Some of the tasks discussed earlier, the basic psychophysiological strategy of investigating reactivity, and the phenomenon of individual differences in psychophysiological response to psychological challenge will all be encountered here.
