Abnormal Psych Ch. 5 Flashcards
Health psychology
the effects of stress and other psychological factors in the development and maintenance of physical problems
behavioral medicine
Concerned with psychological factors that may predispose an individual to medical problems
stressors
an event, situation, or external stimulus that an individual perceives as a threat or challenge, and that causes a stress response in the body
coping strategies
efforts to deal with stress
distress
(bad stress) has the potential to do more damage
Hans Selye noted that stress __________
could occur not only in negative situations but also positive ones
predisposing factors
characteristics that increase the likelihood of a problem developing
Individual characteristics identified as improving one’s ability to handle stress include:
-higher levels of optimism
-greater psychological control or mastery
-increased self-esteem
-better social support
stress tolerance
a person’s ability to withstand stress without becoming severely impaired
The key factors that make one stressor more serious than another are:
-The severity of the stressor
-Its chronicity (how long it lasts)
-Its timing
-How closely it affects our own lives
-How expected it is
-How controllable it is
crisis
times when a stressful situation threatens to exceed, or does exceed, the adaptive capacities of a person
resilience
Healthy psychological and physical functioning after a potentially traumatic event
allostatic load
the biological cost of adapting to stress
Sympathetic-adrenomedullary (SAM) system
one of two major components of the stress systems
a physiological response that helps the body maintain homeostasis, or return to a state of balance, in response to stress
Hypothalamus-pituitary-adrenal (HPA) system
one of two major components of the stress systems
a neuroendocrine system that regulates the body’s stress response
your body’s main way of responding to stress
cortisol
a hormone that helps the body manage stress, blood pressure, and immune function
Psychoneuroimmunology
the study of the interactions between the nervous system and the immune system
Stress-induced immunosuppression
when a person’s behavior and psychological state affect immune system functioning
immune system
a complex network of cells, tissues, and organs that protects the body from disease and infection
Leukocytes (lymphocytes)
“white blood cells”
-a type of blood cell that help the body fight infection and disease
-immune cell that is made in the bone marrow and is found in the blood and in lymph tissue
Two types of leukocytes
1) B-Cells: mature in the bone marrow
2) T-Cells: mature in the thymus
Antigens
foreign bodies like viruses and bacteria, as well as internal invaders like tumors and cancer cells
Cytokines
small protein molecules
-Serve as chemical messengers
-Allow immune cells to communicate with each other
-Play an important role in mediating the inflammatory and immune response
two categories of cytokines
1) Proinflammatory (IL-1, IL-6, and TNF) affects the healing of wounds when production is disrupted
2) Anti-inflammatory (IL-4, IL-10, IL-13) decrease the response that the immune system makes
