Chapter 10 Flashcards
health psychology
an interdisciplinary field that investigates the links among behavior, cognition, and physical health
biopsychosocial model
a way of understanding what makes people healthy by recognizing that biology, psychology, and social context all combine to shape health outcomes
Biopsychosocial model and stress
uncertainty, lack of control, and concern with being evaluated
3 components of health
Biology, Psychology, and Social Context
Stress
a physiological response to an environmental event that is perceived as taxing or even exceeding one’s ability to adapt
general adaptation syndrome
a broad-based physiological response to a physical threat that unfolds in three stages: alarm, resistance, and exhaustion
Sympathetic-adreno-medullary (SAM) axis
a physiological system that governs the body’s immediate response to a stressful event, enabling the ability to flight or flight
Hypothalamic-pituitary-adrenal (HPA) axis
a physiological system that governs the body’s prolonged response to a stressful event, enabling the conservation of energy
challenge reactivity
a cardiovascular pattern of responding to a situation whereby the heart pumps out more blood and the vasculature dilates, allowing efficient circulation through the body
threat reactivity
a cardiovascular pattern of responding to a situation whereby the heart pumps out more blood but the vasculature constricts, preventing efficient circulation through the body
cortisol
a hormone produced by the adrenal cortex that is often elevated in response to stressful events
allostatic load
the sustained activation of many physiological systems in response to frequent or chronic stressors
gene x environment interactions
The interaction between environmental factors and person’s genetic predispositions that determine the unique phenotypes expressed in personality
diathesis-stress model
a model of clinical disorders suggesting that genes provide a susceptibility for a disorder that will manifest as symptoms only under certain levels of stress
differential sensitivities hypothesis
the idea that some people have a genetic predisposition to be more strongly affected by variation in their environment, especially during early childhood
