which is the best conclusion?
it’s mainly chronic stress and not short term stress that is bad for physical health
Vast quantity of peer-reviewed articles is one of the reasons why scientific literature is important. How many peer-reviewed articles are there published in overall science?
3-4/min
What is the difference between physical and psychological stressors?
Physical stressors relate to direct threat, while psychological stressors relate to perceived threat.
What is the correct order in which organs influence each other?
cerebral cortex -> hypothalamus -> pituitary gland -> target organs
What is the function of cardiovascular and hormonal changes in the fight-or-flight response?
Take extra oxygen and fuel to the muscles, suppress other physiological activity, limit tissue damage and strong sensations.
A keyword profile is important for finding cutting edge knowledge and…
a literature review must be variable and replicable
Human stress = preparation without action. What is meant by this?
In stress situations humans, unlike animals, only prepare themselves for action (particularly flight-or-fight response), but are rarely or never able or allowed to perform this action.
Which of the following statements best expresses the essence of the ‘yoked’ control design by Brady, Weiss and others, used to investigate the effect of controllability or predictability of stress on animals?
Both animals are subjected to the same amount of aversiveness, but the animal that has control will experience the most stress.
Sapolsky names at least three traits that result in highest cortisol levels in baboons and correspond reasonably well with human traits that constitute a risk of developing cardiovascular diseases. What are they?
Not releasing frustration; not taking the initiative in a threatening situation; not distinguishing between threatening and neutral situations
Type A personality is found to be the most powerful predictor of cardiovascular disease. Which of its components appeared to be most predictive?
hostility
Low socio-economic status (SES) is found to be a risk factor for disease and premature death. This high risk is due to the fact that compare to people with a relatively higher SES, people with a relatively low SES…
… run this higher risk because of factors such as an unhealthy life style, lower education, and lower income and -independent from these factors- also because they suffer more stress.
Atherosclerosis (clogging/hardening of arteries) is one of the most important chronic diseases in the western world. How can stress contribute to its development?
Stress can cause constant high blood pressure resulting in damage to and inflammation of the blood vessel walls, on which fatty and other materials are deposited.
Why was the discovery of the link between stress and the immune system so important for health?
The immune system is a major defense system against disease agents
Which statement is false? In the stress response, the functions of cortisol include:
a) to support the stress response and to suppress the immune system
b) to support the stress response and at the same time limit damage caused by long-term stress response
c) to support the stress response and strengthen negative sensations such as pain
d) to release extra sugars and fatty acids for burning in the muscles
C) F
Within a stress response, the function of suppressing the immune response (after an initial
increase) is not entirely clear. What is now regarded as the probable function, according to Sapolsky?
To ensure that the initial increase does not cause an autoimmune disease (= ‘attacking the body’s own tissue’)
The best answer to Sapolsky’s ‘Why zebra’s don’t get ulcers’ is:
Animals get fewer stress-related somatic diseases because they experience fewer long-term stressors
