B. Based on the data from Table 14.1, did the effects of the parasympathetic nervous system change with biofeedback? Explain the physiological mechanisms causing the results.

From the data, it cannot be found that whether the parasympathetic nervous system change with biofeedback. The maximum, minimum and average heart rates were greater for the arousal state than the relaxed state. But, both the parasympathetic and sympathetic nervous system is dominating the heart rate. Heart rate will be increased if the subject is under more pressure. However, the reason why it occurred as there was short-term response to acute stress, flight or fight response, from the sympathetic nervous system.

C. Describe a biofeedback program for “stress management.” Include details such as the physiological variable(s) you would measure, the transducers needed, and your criterion for a successful training program.

A biofeedback program for “stress management” would measure heart rate and EDA. The transducers needed would be an EDA and ECG transducer. Small and portable devices would be better, with data sent to smartphone or biofeedback watch, people could monitor respiration

Define biofeedback and explain in general terms how it works.

Biofeedback is used as a signal to learn controlling physiological processes. In order to learn controlling the desired response by the individuals, the sequence that produces the desired response is reinforced by the signal.

F. What change, if any, did your EDA recording show when you were aroused? Relaxed?

In most of the time, the EDA recording increases when aroused. In contrast, the EDA decreases when relaxed.

G. Why is EDA a useful measure for biofeedback training?

EDA mainly measure the sympathetic system. The EDA will decrease if biofeedback is used to increase relaxation. The relationship of EDA to sympathetic activity is a complex response due to EDA response slowly to sympathetic activity and various neurotransmitters is
