Q

Cytotoxic cells

A

type of T cell

“Killer cells” equipped with receptors that match one specific antigen

53
Q

Helper Cell

A

type of T cell

Sentries that travel through the bloodstream hunting antigens and secreting chemical messengers (lymphokines), which stimulate other immune cells

54
Q

Suppressor cells

A

type of T cell

Produce chemicals that suppress immune responding, also alert T and B cells when an antigen is vanquished

55
Q

Primary and Secondary Response

A

With a B CELL
an antigen activates the B cell to produce daughter plasma cells and memory cells as a primary response to fighting infection

Plasma cells manufacture antibodies

subsequent encounters with the antigen cause the memory cells to attack and divide, producing new plasma and memory cells

A

sympatho-adreno-medullary axis

the body’s inital rapid acting repsonse to stress, involving teh release of epinephrine and norepinephrine from the adrenal medulla under the sympathetic nervous system

64
Q

HPA

A

the field of research that emphasizes that interaction of psychological, neural and immunological processes in stress and illness.

Ader and Cohen: Demonstrated immune system could be conditioned

Pert: Found brain receptors for immune molecules that enable brain to influence brain activity

66
Q

Role of the Brain and Nervous System

A

Reticular formation to thalamus to
hypothalamus to limbic system to cerebral cortex
Route for information about a potential stressor
Higher brain regions to reticular formation to target organs, muscles, and glands controlled by sympathetic nervous system
Body mobilized for defensive action

67
Q

General Adaptation Syndrome

A 
GAS
Selye's term for the body's reaction to stress, which consists of three stages:
alarm
resistance
exhaustion

there is a decreased resistance to stress in the beginning, followed by a rebound in resistance to stress. if teh resistance is prol;onged, it will run out, and exhaustion is reached. if exhaustion is reached one is vulnerable to a variety of health problems

68
Q

transactional model

A

LAZARUS
theory that the experience of stress depends as much on the individual’s cognitive appraisal of a potential stressor’s impact as it does on the event or situation itself

Primary appraisal: irrelevant; benign-positive; threatening
Secondary appraisal
Cognitive reappraisal

primary is initial
secondary we assess the coping resources available for meeting the challenge
reappraisal is the constant updating of perception of success or failure

Situations or events are not inherently stressful or unstressful.

Cognitive appraisals are extremely susceptible to changes in mood, health, motivation.

The body’s stress response is nearly the same, whether a situation is actually experienced or merely imagined.

69
Q

Diathesis-Stress Model

A

Individual’s susceptibility to stress and illness is determined by two interacting factors:
Predisposing factors (in the person)
Genetic vulnerability
Acquired behavioral or personality traits
Biological system reactivity

Precipitating factors (from the environment)
Traumatic experiences
70
Q

Post-Traumatic Stress Disorder (PTSD)

A

Psychological disorder triggered by exposure to an extreme traumatic stressor

Associated with combat and catastrophic environmental events

Recognized as an independent disorder during the Vietnam War

Psychological symptoms include haunting memories and nightmares, mental distress, flashbacks

71
Q

Daily hassles

A

Concern about weight, health, appearance, too much to do
May impact the unborn
May be symptoms of stress
Can interact with background stress

Hassles have proven to be a better predictor of health problems than major life events or the frequency of daily uplifts.

72
Q

Daily uplifts

A

Relating well with friends, completing a task, getting enough sleep

73
Q

Work overload

A

People who feel they have to work too long
and hard at too many tasks feel more stressed, have poorer health habits, experience more accidents and more health problems.

74
Q

Role overload

A

Problem associated with juggling multiple roles simultaneously
Scarcity hypothesis
Enhancement hypothesis

Scarcity hypothesis
Because time is limited, multiple roles are damaging
Enhancement hypothesis
The benefits of meaningful work in enhancing self-esteem outweigh the costs

75
Q

Burnout

A

Job-related state of physical and psychological exhaustion

Jobs that involve responsibility for other people appear to have higher levels of burnout.
For example:
Nurses
Firefighters
Air traffic controllers

Burnout is not an inevitable employment consequence.

76
Q

Significant life events

A

Holmes and Rahe research: Life change units (LCUs)

The Social Readjustment Rating Scale (SRRS) attempts to quantify life events in terms of life change units.
First systematic effort to link stress and illness
Faulted for subjectivity and failing to consider individual differences in cognitive appraisal

77
Q

Problem-focused coping

A

efforts to deal directly with a stressor by applying problem-solving skills to anticipate and prevent potential stressors or by directly confronting the source of the stress

78
Q

emotion-focused coping

A

efforts to control your emotional response to a stressor either by distancing yourself from it or changing how you appraise it

79
Q

gender differences in coping

A

Physiological differences
Men: Stronger catecholamine reactivity to stressors
May reflect tendency of men to be more hostile than women
Emphasize problem-focused coping

Women: Stronger glucocorticoid response
May help explain gender differences in coronary disease
Emphasize emotion-focused coping

80
Q

Resilience

A

Ability of some children to spring back from sometimes overwhelming stressors that might otherwise disrupt well-being
Associated with many adult characteristics including forgiveness, sense of coherence and life purpose, self-efficacy, less depression, anxiety, and perceived stress
Origins
Individual traits: easy temperaments; high self-esteem; sense of personal control; well-developed academic, social, and creative skills (social cognition)
Social support

81
Q

Explanatory style

A

Person’s propensity to attribute outcomes to positive causes or negative causes

82
Q

Pessimism

A

Negative explanatory style

Attributions that are global, stable, and internal

Tendency to ruminate and passively disengage

Associated with anger, hostility, depression, smoking, alcohol and drug abuse; linked to early mortality

Pessimists experience more unpleasant events, which have been linked to shorter lives.

Pessimists believe that “nothing I do matters,” so they are less likely than optimists to comply with medical regimens or take preventive actions (such as exercising).

Pessimists are more likely to be diagnosed with major depressive disorder, which is associated with mortality.

Pessimists have weaker immune systems than optimists.

83
Q

Optimism

A

Positive emotions increase a person’s physical, cognitive, and social resources.
Positive explanatory style and active engagement
Related to shorter hospital stays, faster recoveries, longer and healthier lives
Promotes healthier lifestyles
May also help sustain immune functioning
(C-reactive protein)

Broaden-and-build theory
Positive emotions increase physical, cognitive, and social resources, which in turn help people cope more effectively with stressful experiences and live healthier lives.

Unrealistic optimism
If a person thinks good outcomes are bound to happen, he/she may not do anything in the face of illness.

Optimistic bias
Belief that other people are more likely than oneself to develop a disease, be injured, or experience other negative events

Learned optimism can occur when early life identified pessimism changes to optimism.
Adversity
Beliefs
Consequences

84
Q

Personal Control and Choice

A

The belief that people make their own decisions and determine what they do or what others do to them

Self-efficacy (Albert Bandura)

Associated with adaptive, problem-focused coping and healthier lifestyle behavior

85
Q

Regulatory control

A

Ways in which people modulate their thinking, emotions, and behavior over time and across changing circumstances
Good regulatory control
Calmer, able to delay gratification, control emotions, more problem-focused coping

Less effective control (under-controlled)
Impulsive, unable to delay gratification, aggressive, venting

86
Q

Social Support

A

Companionship from others that conveys emotional concern, material assistance, or honest feedback

People who perceive strong social support experience:
Faster recoveries
Fewer medical complications
Lower mortality rates at any age (Alameda
County study)
Less distress in the face of terminal illness

Buffering hypothesis
May mitigate stress indirectly through the use of more effective coping strategies

Direct effect hypothesis
May enhance the body’s physical responses to challenging situations
Better immune functioning
Encourages healthier lifestyles
Better relationships with doctors, nurses, etc.

People with better social skills receive more support.

Angry and hostile people receive less support than agreeable people do.

Angry people report more negative life events.

Angry people make others feel more stress.
Social support may actually backfire when:
It is not wanted or is inadequate
The type of support offered is not what
is needed at the moment
Too much social

87
Q

Relaxation Therapies

A

Progressive muscle relaxation

Relaxation response - a meditative state of relaxation in which metabolism slows and blood pressure lowers

Deep breathing and visualization

Positive self-affirmation or self-talk
