Q

What waves are involved with stage 0 of sleep?

A

This is the waking stage.
Beta waves emerge when you are alert, responsive, and are able to hold intelligible conversation
They are high frequency low amplitude waves with an irregular pattern
Alpha waves emerge when you close your eyes and start to relax- you can get hypnagogic images or jerks

37
Q

What is pain?

A

The body’s response to stimuli intense enough to cause real or threatened tissue damage
It is unpleasant, but functions as a warning signal that our wellbeing is threatened. This allows us to remove the source of pain to try to heal ourselves

38
Q

What is the biomedical vs subjective view of pain?

A

Biomedical: The extent of pain severity is proportional to the amount of tissue damage.
Everyone with the same injury should experience the same amount of pain
Subjective: People with the same amount of tissue damage experience different pain, which has to do with psychological state

39
Q

What are the three theories of chronic pain?

A

Gate-control theory
Operant conditioning theory
Cognitive behavioural theory

40
Q

What is the gait-control theory of pain

A

A ‘gate’ exists at the spinal cord, receiving information in 2 directions:
Messages going up carry pain messages to the brain
Messages going down (psychological) can close or open the gate, involving context, interpretation, attention and past experience

41
Q

What is the operant conditioning theory of pain?

A

Our natural response to pain is to move away from the source, making it negative reinforcement- we remove the negative stimulus and are less likely to seek it out again
However, with chronic pain, positive reinforcement may emerge in the form of sympathy or negative reinforcement in that we don’t have to do something because we’re sore. This can reinforce the behaviour and cause it to continue

42
Q

What is the cognitive behavioural model theory of pain?

A
  • Patients’ appraisals and coping strategies are crucial as pain perception is in the brain
    Negative expectations about control can maintain pain
    Passive coping strategies (ie inactivity) can maintain pain
    Active coping encourages a problem solving attitude
43
Q

What are behavioural and cognitive ways in which pain can be treated?

A

Behavioural- Resting too much shouldn’t happen, so you should continue to live a normal life
Cognitive- Reduce anxiety and sympathy from others
Seek distraction from pain and address expectations of control

44
Q

What does AAAF stand for in terms of what affects memory?

A

Attention
Arousal

Recentness of material
46
Q

What are the 4 reasons for forgetting something?

A
  • Failure to encode due to lack of attention/rehearsal/stress
  • Interference from competing info
  • Decay due to time
  • Repression of painful memories
47
Q

What are the 5 stages of behaviour change?

A

Understanding of why change is necessary
Motivation
Self efficacy
Knowledge of skills and barriers to change

49
Q

52
Q

What is psychological and social development in early childhood?

A
  • Preoperational stage
  • Literal understanding of the world
  • Poor memory
  • Dependent on caregivers
  • Model others’ behaviours
53
Q

What are health promotion strategies that can be used in early childhood?

A
  • Target the family, not the child
  • Deliver concrete concepts
  • Combine learning with enjoyable activities
  • Role model behaviours
54
Q

What is psychological and social development in early adolescence?

A 
Concrete thinking
Grasp moral concepts and can assess them
Understand body image
Realize they are different from their parents
Start of strong peer groups
Start of risk behaviours
55
Q

Concrete materials- focus on current impacts on their health
Focus on the here and now
Use peer educators and role models

56
Q

What is psychological and social development in mid adolescence?

A

Development of abstract thinking, but in relation to others- not self, as they think they’re invincible
Increased autonomy

57
Q

What are health promotion strategies that can be used in mid adolescence?

A

Body image targeting
Highlight how others can be harmed by things or behaviours
Here and now is more motivating than ‘in future’

58
Q

What is psychological and social development in late adolescence?

A

Abstract and complex thought
More development of body image
Autonomy
Large groups split into small groups and couples

59
Q

What are health promotion strategies that can be used in late adolescence?

A

Address all the possible outcomes of actions

Target messages at parter and friend consequences

60
Q

What are the areas of the health behaviour model?

A 
Perceived susceptibility
Perceived severity
Benefits and barriers
Cues to action
Self efficacy
(All lead to a health behaviour)
61
Q

Why are perceived susceptibility/severity important in health behaviour model?

A

It impacts on the perceived threat of an illness. If perceived threat is high, there will be higher motivation to improve behaviour

62
Q

How do benefits/barriers impact the health behaviour model?

A

Impacts perception of how effective the behaviour would be at reducing/avoiding specific and related conditions
Identifies costs of related action

63
Q

What are the limitations of the health behaviour model?

A

Not all beliefs occur simultaneously- others will crop up before and after appointments
Assumes human rationality, but some people will see benefits and barriers irrationally
Could underestimate or oversimplify the role of a threat
(fear can also promote denial, not just action)
Little acknowledgement of societal impact

64
Q

What is the theory of planned behaviour?

A

Attitude toward behaviour, subjective norms and perceived behavioural control all affect one another, and lead into intention, and then behaviour.
However, this assumes that people act according to how others act and think

65
Q

What are some characteristics of clinicians which enhance the placebo effect?

A 
High status
Formal medical setting
Clear indication of expected improvement
High confidence
Warmth and empathy
66
Q

What is problem solving?

A

A cognitive process directed towards specific situations

67
Q

What is decision making?

A

Process of choosing between alternatives, involving weighing up the pros and cons using judgement

68
Q

What is an algorithm?

A

Step by step procedure that always provides the right answer

69
Q

What are heuristics and when are they used?

A

Mental shortcuts in decision making
Although, they can lead to an increase in memory errors and in estimating likeliness of outcomes
Therefore, it’s only used when algorithms are unavailable

70
Q

What are 5 common barriers to problem solving?

A
  • Distraction: noise, discomfort, presentation and representation of material, overload
  • Functional fixedness: Use items only for its ‘intended’ function
  • Mental set: Continuing to use strategies that worked in the past but are no longer optional
    Unnecessary constraints: Tend to impose unnecessary constraints on possible solutions
  • Confirmation bias: see only the information confirming our predetermined conclusions
71
Q

What is framing?

A

A particular depiction of a choice that can be positively or negatively emphasized.

72
Q

How can framing be avoided?

A

People make bolder choices to avoid a loss than to achieve a gain
Need to prevent information in a balanced way
Use debiasing strategy, such as asking why patients made a certain choice

73
Q

Are schemas top-down or bottom-up processes?

A

Top-down as our existing knowledge is applied to fill in gaps
