Psychophysiological Stress Assessment Using Biofeedback

Locus of control, learned helplessness, and control of heart rate using biofeedback
Abstract:
Subjects were 24 male undergraduate students. False biofeedback was provided to give the impression of success or failure (helplessness) on a preliminary task. Authentic biofeedback was then provided for control of heart rate. Subjects were administered pre- and post-locus of control scales using Levenson's multidimensional scales. A significant relationship between locus of control and success or failure conditions added validity to Levenson's approach. Results and future research are discussed.

Regulation of Heart Rates
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
