Description

Lab Homework 1) Did parasympathetic activity change with relaxation? Arousal? Explain the physiological mechanisms causing the results. Parasympathetic should increase during relaxation. We would observe this by seeing a decrease in heart rate and EDA. The opposite should happen during stress. 2) Describe a biofeedback program for “stress management.” Include details such as the physiological variable(s) you would measure. There are numerous physiological variables that could be measured and shown to the participant in order to teach about the effects of stress on their body. Potential variables to measures would include HR, EDA, EEG, blood pressure, and ECG. 3) Name the branches of the autonomic nervous system and briefly explain their function. Sympathetic ( fight or flight) and Parasympathetic (digest and rest) nervous system. 4) In your own words define Biofeedback and explain in general terms how it works. Numerous answers possible. Briefly, biofeedback involves using measures of our own physiology to learn about our responses to stimuli. By seeing a real-time measure of our physiological response, we can learn to decrease harmful sympathetic nervous system activity by controlling our responses to stimuli. 5) Why is EDA a useful measure for biofeedback training? Any stressful situation would be expected to increase electrodermal activity (EDA). EDA is an indirect measure of the sympathetic nervous system. The sympathetic nervous system increases activity of sweat glands, therefore increasing electrical conductivity of the skin....
