Social psychology and health Flashcards
Psychological stress
Sense that challenges and demands surpass one’s current capacities, resources and energies. It is persistent.
Define rumination and explain why we experience it vs other animals
As humans, we experience rumination: consistently thinking about negative (stressful) events/emotions. Other animals live in the moment…stress goes away when there is no more danger.
Explain Selye’s concept of general adaptation syndrome
The body mounts a similar set of responses to a broad array of stressors.
Stress is “the nonspecific response of the body
to any demand” and these responses mobilize the organism for action, but can make you sick if they go on for too long
Explain how Hans Selye’s work contributed to understanding of stress
Working on rats, Selye was studying a newly discovered ovarian hormone. When injected with this hormone, these rats developed ulcers, enlarged adrenal glands, shrunken immune tissues
BUT same effects on control group…it was actually linked with the way Selye was clumsy with the rats
What is the function of the hypothalamus
- key role in coordinating motivated behaviors required for survival (ex: flight-or-flight response)
- control both the quick and slow response processes
- inputs “neural alarm system”
Describe the quick pathway for processing of events
SNS permits an immediate response to an arousal initiated by the hypothalamus. SNS= Survival, stress responses
After the emergency, the PNS inhibits SNS, and restores the body
How does the SNS perform the fight or flee response?
(steps)
- Arousal initiated by the hypothalamus
2.Stimulation of the adrenal glands–>secretion of epinephrine - Increased blood pressure, heart rate, sweating, etc.
Describe the slow pathway for processing of events (and the steps)
HPA axis
1. Stressful event stimulates the amygdala
2. Hypothalamus initiates a chemical cascade, stimulation of the pituitary gland
3. Stimulation of the adrenal glands
4. Release of cortisol
How does cortisol works on our physiology
- mobilizes sugar for fuel
-increasing heart rate, blood pressure - directs attention towards threat
- contributes to the formation of “flashbulb memories”
How can chronic stress affect the cardiovascular system
Contribute to plaque build-up on arterial walls, increasing the risk of heart attacks
(Chronic stress can impair PNS activation…SNS ++ activated…heart rate/blood pressure constantly higher)
How can chronic stress affect the immune system
- slow down wound healing
*ex: experiment on students during exam period vs.
vacation - virus contraction
*ex: experiment with cold virus exposure…most
people who got sick were chronically stressed
-glucocorticoid resistance: immune cells can no longer respond to cortisol
… prolonged inflammatory response
Contrast the biomedical and biopsychosocial models of health and disease
Biomedical: Diseases are caused by issues coming from the body only…mind-body dualism
Biopsychosocial: Health is derived from the interaction of biological factors, as well as psychosocial factors…Mind processes can produce bodily changes
What allows human brain capable to anticipate and dwell on potential and past experiences, prolonging our stress?
Highly developed prefrontal cortex
What causes stress-related diseases?
Frequent activation of physiological systems designed for acute emergencies, because of long-term worrying.
Describe the Trier Social Stress Test and explain how it utilizes these two ingredients
Interview speech given in front of panel judges, followed by surprise mental math task.
- Uncontrollability: Lack of social feedback + Math task
- Social-evaluative threat
