3.7 - Stress (set C - Personalty Types A, B And C + Hardiness And Drug Therapy) Flashcards
(48 cards)
What is personality?
A set of characteristic behaviours , attitudes and general temperament that remain relatively stable and distinguish one individual from another
- fundamental thing that makes us who we are and different from others
Outline the characteristics of type A personality?
- impatient
- competitive
- hostile and aggressive
- time urgent
very time pressured (have to do it themselves, wont let others do it for them) and rushing - linked to stress, as they continue experience fight or flight response - increase in stress hormones (adrenaline) which can lead to CHD
Outline the characteristics of type B personality?
- relaxed
- one thing at a time
- patient
- express feelings
more laid back and patient so are less vulnerable to stress-related illnesses
Outline the characteristics of type C personality?
- people pleaser (try and accommodate everybody)
- suppression of negative emotions (do not show outward signs of anger)
- emotionally dysfunctional
- external locus of control (seek others for behaviour)
incur a risk of cancer due to some stressors activation the ANS and chronic stress impacting on the immune system
Outline the study conducted by Friedman and Rosenman on personality types?
Wanted to test hypothesis that type A individuals (noticed the impatience, hostility and competitiveness) were more likely to develop CHD than type Bs
- obtained a self-selected sample of 3200 men - longitudinal study which involved a structured interview (constantly interrupted participants and observed their behaviour in response) and a questionnaire
- assigned to either type A, B or X (equal amounts of A and B) - would then see the participants again 8 1/2 years later
Outline the findings of the study conducted by Friedman and Rosenman on personality types?
257 participants had developed CHD - 70% of them were classified as type A
Other factors known to be associated with heart disease (smoking, obesity and blood pressure) were taken into account
- compared to type B - type As were found to have higher levels of adrenaline and noradrenaline and cholesterol
significant but moderate positive correlation found between personality type and CHD
Outline research which distress with type A and its relation to CHD?
Ragland and brand - carried out follow up study
- study confirmed importance of CHD risk factors (age, smoking and high BP) found little evidence of a relationship between Type A behaviours and morality challenges Friedman and rosenman research
Outline research for personality type C - involving Vietnam veterans?
Studied 200 people from Vietnam war - 75 had cancer diagnosis
- completed self-report questionnaire - veterans diagnosed with cancer scored much higher on the repression of emotions but lower on depression scale compared to non-cancer group
- support idea that repressing emotions may increase vulnerability to illness (depression would not become evident as they have repressed acknowledging they feel depressed
Explain the 3 characteristics of hardy people suggested by Kobasa?
- commitment - hardy people throw themselves into life, believing they will get something valuable
- challenge - they are resilient and welcome change as opportunity rather than threat
- control - active rather than passive - believe they are in charge of what happens to them (internal locus of control)
people who thrive is stressful situations have hardiness
Outline and explain research by Kobasa?
- asked by workforce to identify people in workforce who are able to cope with stressful situations (Kobasa said hardy people are less likely to suffer from stress - can cope more effectively)
- 800 middle and upper level executives from large company - asked them about life events of last 3 years (gave them SRRS) and any illnesses in that period
Outline and explain findings and conclusion from Kobasa research?
- findings - 150 have high SRRS score - identifies 2 groups - first group had high stress and low illness (86) - second group had high stress and high illness (75)
- Kobasa found those that were highly stressed but experienced low illness scored high on all 3 hardiness characteristics - suggests that to have a hardy personality it modified the effects of stress and illness
Outline application for hardiness?
- US navy seals screen for hardiness to ensure recruits are capable of dealing with the struggles of war
- mental fitness now being assessed alongside physical
- can be applied to students to increase hardiness and how students deal with stress for exams
Explain what happens focusing on chemicals and internal activity when we experience stress?
Increase in neurotransmitter GABA
Increased activity within lambic system (which regulates ANS)
Increased activity in sympathetic nervous system
can not prevent these things happening when we experience a stressful situation - we can calm them down
Outline and explain how BZs work focus on their function with GABA?
1) BZs enhance the action of GABA
2) GABA is a neurotransmitter that natural helps calm the CNS
3) BZs bind to GABA receptors
4) receptors are blocked - making it difficult to be stimulated by other neurotransmitters (eg serotonin)
5) causes an overall calming effect on the CNS
Explain how BZs are used to treat stress - how do they work?
Most common drug used to treat stress and anxiety - slows down the CNS activity
1) GABA is neurotransmitter responsible for anxiety relief with 40% of neurones in brain responding to GABA
2) BZs enhance GABA by binding to its receptors and slowing activity of postsynaptic neurone boosting action of GABA and reducing serotonin activity in the brain (neurotransmitter which causes arousal - leading to less stress) this slows the CNS
Explain what the drug therapy beta-blockers (BB) do?
Reduces activity of adrenaline and noradrenaline (both involved in fight or flight response)
- initially developed for heart problems - application for stress and anxiety discovered
- effective in variety of stressful situations eg among musicians and in sports which are accuracy intensive (investigated 2000 musicians in orchestra and found that 27% reported taking BBs - those musicians who took BBs felt better about their performance)
Explain how beta-blockers work?
Bind to receptors on the cells of the heart and other parts of body stimulated during arousal - lowers adrenaline/noradrenaline action to reduce physical symptoms of anxiety
lower heart rate and less stress on heart - which causes fall in BP and decrease in anxiety
What is biofeedback?
Heart rate and BP are not under our voluntary control, controlled by ANS - biofeedback is a method were an individual learns to exert voluntary control over involuntary behaviours by being made away of what is happening in the ANS
Explain millers belief on biofeedback?
- showed that such autonomic processes (muscle tension and heart rate) were controllable - led to creation of biofeedback
- works on principles of operant conditioning (of involuntary responses) and psychology (relaxation techniques)
- considered a biological management method - involves playing attention to heart beat and BP
Explain how biofeedback treatment works?
- involves individual being connected to a machine via electrodes that provides feedback (visual or auditory) on ANS arousal signs of stress (heart rate or muscular tension)
- heart rate measured - feedback will indicate if its too high or OK
- series of things that you’ll do (relaxation techniques) to help reduce the responses of the SNS and activate the parasympathetic nervous system
Explain relaxation techniques used in biofeedback?
- relaxation techniques reduce the activity of SNS and activate the parasympathetic nervous system - slows heart rate and makes them feel relaxed (adrenaline and noradrenaline no longer produced)
- could be breathing techniques or muscle relaxation
- relaxation acts like a reward with feedback from monitor helping to positively reinforces the behaviour (will require practise to relax without feedback from monitor)
Outline research into biofeedback - looking at its effect on group of patients + which does not support technique?
Doctors taught techniques for biofeedback and used for around a month - reported reduced levels of stress (measured through questionnaire) compared to control group who didn’t get feedback
- also measured physiological symptoms (heart rate, BP) in same patients and found no significant changes - suggests it may act as a placebo effect
Outline research into biofeedback - focus on investigation in treating tension headaches?
Researcher assigned 18 participants who were experiencing tension headaches into 3 groups of 6 (group A, B and C)
Group A - had biofeedback sessions
Group B - were taught relaxation techniques
Group C - control - received no intevention
group a reported significant reduction in headaches - shows biofeedback can be effective
What are the advantages of biofeedback as a treatment for stress?
- can be used on children - drugs can not (due to risks and ethical problems)
- once trained if stress returns they will be capable of dealing]
- no side effects + wont get addicted
- research support suggests they work - study looking at treatment for tension headaches found group which were taught biofeedback reported significant decrease
