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

Q

What waves are involved with stage 1 of sleep?

A

Slow theta waves
This stage is only a few minutes long during the shift from drowsiness to sleep
Your blood pressure drops and your eye movement slows
You’ll think you weren’t sleeping if you’re awoken in this stage
The waves decrease in frequency and increase amplitude towards stage 2

25
What waves are involved with stage 2 of sleep?
Large theta waves This is when sleep deepens, but is still light Involved with memory consolidation and synaptic pruning Theta waves are interrupted by sleep spindles and K complexes Alpha waves disappear and waves get slower
26
What waves are involved with stage 3 of sleep?
Less than 50% delta waves These are slow Combined with stage 4 this is called delta sleep
27
What waves are involved with stage 4 of sleep?
More than 50% delta waves
28
What waves are involved with REM sleep?
Beta waves, meaning it's similar to waking This is where most vivid dreams occur The waves are high frequency and low voltage HR & BP increases, as well as resp rate and eye movement
29
What happens during stage 1 of sleep?
You're easily awakened Muscles relax and may twitch Eye movements slow
30
What happens during stage 2 of sleep?
``` Breathing and HR are regular Body temp drops Loss of sense of place Brain waves slow Eye movement stops ```
31
What happens during stage 3/4 of sleep?
``` Decreased BP Muscles relax Tissue growth/repair Energy restored Release of hormones Slowest brain waves ```
32
What happens during REM sleep?
Brain is actively dreaming Eyes dart rapidly Muscles paralyzed Irregular breathing and HR
33
What are biological factors that affect sleep?
Age Illness Jet lag
34
What are psychological factors that affect sleep?
``` Thinking style Anxiety Daytime napping Pain Bedtime ritual ```
35
What are social/environmental factors that affect sleep?
Other people Light Temperature
36
What can result from sleep deprivation?
Obesity due to decreased hormone secretion CVD due to interruption of natural BP decrease Mood becoming irritable/tense Impaired self regulation Diabetes due to insufficient regulation of insulin Memory and reaction defecits
37
What is pain?
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
What is the biomedical vs subjective view of pain?
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
What are the three theories of chronic pain?
Gate-control theory Operant conditioning theory Cognitive behavioural theory
40
What is the gait-control theory of pain
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
What is the operant conditioning theory of pain?
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
What is the cognitive behavioural model theory of pain?
- 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
What are behavioural and cognitive ways in which pain can be treated?
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
What does AAAF stand for in terms of what affects memory?
Attention Arousal Acuity of Senses Function of brain
45
What affects the speed at which new information is forgotten?
``` Difficulty of information Meaningfulness Its representation Physiological factors How it was remembered and how often it is revised Recentness of material ```
46
What are the 4 reasons for forgetting something?
- Failure to encode due to lack of attention/rehearsal/stress - Interference from competing info - Decay due to time - Repression of painful memories
47
What are the 5 stages of behaviour change?
Precontemplation: do not recognize a problem Contemplation: Acknowledge a problem but not changing Preparation: Getting ready to change and gathering knowledge of how to do so Action/Willpower: Change occurs: initial adoption of new habits Maintenance: Ongoing change preventing relapse
48
What is necessary for a successful behaviour change?
Understanding of why change is necessary Motivation Self efficacy Knowledge of skills and barriers to change
49
Why start a behaviour change programme in adolescence?
Health behaviours in adolescence continue into adulthood Has immediate impact on adolescent health Young people have different needs for information delivery compared to adults It can take time to change behaviour Health risks are often clustered
50
What are the 4 ways health can be improved in adolescents?
Change society as a whole on behalf of adolescents- eg. drunk driving laws, smoking laws, family planning Health Education Improving adolescents' social skills Reducing SES inequalities
51
What are the 5 levels of health promotion delivery in adolescents?
Individual- eg. peer mentoring Family- eg. parental training School- eg. curriculum education and policies Community- eg. changing local environments & policies National- eg. healthcare, employment, marketing laws
52
What is psychological and social development in early childhood?
- Preoperational stage - Literal understanding of the world - Poor memory - Dependent on caregivers - Model others' behaviours
53
What are health promotion strategies that can be used in early childhood?
- Target the family, not the child - Deliver concrete concepts - Combine learning with enjoyable activities - Role model behaviours
54
What is psychological and social development in early adolescence?
``` 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
What are health promotion strategies that can be used in early adolescence?
Concrete materials- focus on current impacts on their health Focus on the here and now Use peer educators and role models
56
What is psychological and social development in mid adolescence?
Development of abstract thinking, but in relation to others- not self, as they think they're invincible Increased autonomy
57
What are health promotion strategies that can be used in mid adolescence?
Body image targeting Highlight how others can be harmed by things or behaviours Here and now is more motivating than 'in future'
58
What is psychological and social development in late adolescence?
Abstract and complex thought More development of body image Autonomy Large groups split into small groups and couples
59
What are health promotion strategies that can be used in late adolescence?
Address all the possible outcomes of actions | Target messages at parter and friend consequences
60
What are the areas of the health behaviour model?
``` Perceived susceptibility Perceived severity Benefits and barriers Cues to action Self efficacy (All lead to a health behaviour) ```
61
Why are perceived susceptibility/severity important in health behaviour model?
It impacts on the perceived threat of an illness. If perceived threat is high, there will be higher motivation to improve behaviour
62
How do benefits/barriers impact the health behaviour model?
Impacts perception of how effective the behaviour would be at reducing/avoiding specific and related conditions Identifies costs of related action
63
What are the limitations of the health behaviour model?
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
What is the theory of planned behaviour?
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
What are some characteristics of clinicians which enhance the placebo effect?
``` High status Formal medical setting Clear indication of expected improvement High confidence Warmth and empathy ```
66
What is problem solving?
A cognitive process directed towards specific situations | Moves from initial state to a goal state via mental processes
67
What is decision making?
Process of choosing between alternatives, involving weighing up the pros and cons using judgement
68
What is an algorithm?
Step by step procedure that always provides the right answer
69
What are heuristics and when are they used?
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
What are 5 common barriers to problem solving?
- 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
What is framing?
A particular depiction of a choice that can be positively or negatively emphasized.
72
How can framing be avoided?
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
Are schemas top-down or bottom-up processes?
Top-down as our existing knowledge is applied to fill in gaps
