Document Summary
Explain the biopsychosocial model of health psychology. Emotional instability: e. g. , irritability and losing temper, hypersensitivity and crying, etc Problem solving difficulties: e. g. , trouble making decisions, poor choices, easily frustrated. Ruminative thinking: obsessively worrying and intrusive disturbing mental images. Catastrophizing: using extreme absolute language, over-reacting to minor problems, etc: explain how the sympathetic adrenal medullary (sam) system operates. Stress is perceived by the cerebral cortex which signals the hypothalamus to activate the sympathetic nervous system (fight or flight). This stimulates the adrenal medulla glands to secrete catecholimines, epinephrine, and norepinephrine. The effects are raised blood pressure, irregular heart rate, sweating, and constriction of peripheral blood vessels: explain problem-focused and emotion-focused coping. Problem-focused coping is aimed at reducing the demands of the stressful situation or expanding the resources available to deal with the stressor, i. e. , dealing directly with the problem or situation.
