What is biofeedback and how does it work?
• Biofeedback: mind-body technique that helps teach patients how to influence their autonomic nervous systems - the part of the body that controls involuntary physical functions such as blood pressure, heart rate, muscle tension, and brainwave frequency.
What is the role of positive feedback in the thyroid?
Most physiologic control systems function under positive feedback mechanisms. When thyroxine (T4) in the thyroid is low, it triggers the pituitary to increase thyroid stimulating hormone (TSH), which then increases T4 secretion.
What does biofeedback read out in degrees Fahrenheit?
Biofeedback devices typically read out in degrees Fahrenheit as the indicator of peripheral vasoconstriction; thus only indirect access to peripheral vasoconstriction is possible in biofeedback Three tasks of an emg machine? a.
What is the difference between operant conditioning and feedback?
Getting feedback helps people learn to control functions. - Operant conditioning is a form of feedback. It is feedback provided in the form of positive or negative results of a particular behavior. **What is biofeedback?
What determines the nature of a stress response?
b. The nature of a stress response is determined by the objective severity of the stressor.
Which gland is responsible for growth, metabolism, and maturation?
d. The pituitary gland is ultimately responsible for growth, metabolism, and maturation, all of which are important when the body is stressed.
Which factor stimulates the release of norepinephrine?
b. The corticotropin-releasing factor stimulates the release of norepinephrine, which is responsible for "fight-or-flight" reaction to stress.
What is the acute stress reaction associated with?
d. primarily, this acute stress reaction is associated with stimulation of the autonomic nervous system that causes stiffness in the joints.
What is feedback in psychology?
Getting feedback helps people learn to control functions. - Operant conditioning is a form of feedback. It is feedback provided in the form of positive or negative results of a particular behavior.
What degree is biofeedback read out in?
d. Biofeedback devices typically read out in degrees Fahrenheit as the indicator of peripheral vasoconstriction; thus only indirect access to peripheral vasoconstriction is possible in biofeedback
What is the goal setting of a patient?
b. Goal setting - help patients identify and assess their goals and make them manageable, explicit, operational
Why was behavioral medicine developed?
a. Behavioral Medicine developed because traditional medical approaches were insufficient for managing and treating many chronic diseases or maladaptive behaviors
Can biofeedback measure peripheral blood vessels?
a. Biofeedback device cannot directly measure the changing diameter of peripheral blood vessels or the smooth muscle activity that brings about these changes
