Q
What is statistical infrequency
A
When an individual has a a less common characteristic to the population in terms of statistics
2
Q
Explain this idea
A
People who fall into the general statistic for a certain characteristic are classified as normal but people are pronounced as abnormal is they don’t show the same characteristic
3
Q
What is the normal distribution
A
This is the idea that for a certain characteristic people tend to cluster around a certain average score
4
Q
What’s the normal distribution for IQ
A
Average IQ 100 (68%) of people have a score from 85 to 115 which only 2% of people scoring below 70 these people are classified as abnormal
5
Q
What is deviation from social norms
A
Behaviour that is different from the accepted standards for society
6
Q
What determines this norm
A
Society decides what is classifed as normal with it varying between different social groups or eras in time. There are very little behaviours which are deemed as universally abnormal
7
Q
Example for social norms
A
Homosexuality considered abnormal in the Uk past but now is legalised and commonly accepted but in places like Brunei there are laws (2019) that enforce punishment in this case death
8
Q
What is the DSM-5
A
manual used by psychiatrists to classify mental health disorders
9
Q
What an example of deviation from social norms
A
Antisocial personality disorder, causes irresponsible and aggressive actions which are caused by lack of moral standards and acceptance of social norm

11
Q
Real world application(statistical infreq)
A
A strength of statistical infrequency is its usefulness.
used in clinical practice for diagnosis
Eg intellectual disability IQ below 70.
Beck depression inventory assessment tool, people with a score of 30+ are interpreted as severely depressed
Shows its use in diagnostic and assessment processes
12
Q
Unusual characteristics may be positive(statistical infreq)
A
Limitation is that the characteristic could be positive as well as negative.
Eg people with IQs above 130
If someone gets really low on BDI(becks depression inventory it isn’t seen as abnormal)
It is useful but isn’t sufficient as the sole basis to define abnormality
13
Q
Real world application(dev from social norms)
A
Strength being its usefulness in the real world
Key feature of psychopathy is failure to conform to culturally accepted behaviour. Also used in diagnosis of schizotypal personality disorder where strange used to evaluate way of thinking looks and actions
14
Q
Cultural and situational relativism
A
Limitation is variability of social norms between different culture and eras
Peoples labelling of abnormality is do with moral standards and cultures
Eg aggressive and manipulative behaviour is more accepted in corporate deal making compared to a family context.
Difficult to tell if someone is truly abnormal as there is no real standard only assumptions
15
Q
What is failure to function adequately
A
When someone isn’t able to cope with the ordinary demands of day to day life
16
Q
What counts as failure to function adequately
A
Being unable to maintain good hygiene, being unable to hold down a job or maintain healthy relationships with those around them
17
Q
Who cam up with the signs that someone may be FTFA
A
David Rosenhan and Martin Seligman(1989)
-cant maintain standard of interpersonal rules(eye contact)
-Severe personal distress
-A persons behaviour becomes irrational or dangerous to themselves
18
Q
What is deviation from ideal mental health
A
When someone doesn’t met criteria for good mental health
19
Q
What does ideal mental health look like and who came up with it?
A
Marie Jahoda(1958) came up with these criteria
- No symptoms of distress
-ration and perceive ourselves accurately
- self actualise(strive to reach potential)
-cope with strss
-realistic view of the world
- good self esteem and lack guilt
-independent of other people
-can successfully work love and leisure

A
21
Q
Represents a threshold for help(FTFA)
A
Strength is that it sets a good threshold for professional help
most people have some symptoms of mental health disorder 25% of people will have mental health problems in a given year
This criteria suggests people who require help the most are able to receive it
22
Q
Discrimination and social control(FTFA)
A
A limitation of FTFA is that it is easy to label non standard lifestyles as abnormal. Eg people may not be having problems with functioning adequately instead they may be choose to deviate form the normal standards eg those who partake in high risk activities
Means people who make unusual choices are labelled as being abnormal
23
Q
Comprehensive definition(IMH)
A
Strength is that is has a comprehensive definition
range of criteria from distinguishing mental health from mental health disorder,
Mental health is discussed meaningfully which different views. Provides a checklist for to asses ourselves and others
24
Q
May be culture bound
A
A limitation is that is that there are different elements which are not applicable across cultures
25
what is a phobia
an irrational fear of a situation or object
26
What types of characteristics are there in phobias
Behavioural(how we act), emotional(how we feel or our mood, cognitive(knowing reasoning, thinking, remembering and believing)
27
explain phobias
excessive fear and anxiety triggered by object place or situation, the extent of fear is out of proportion to the real danger(phobic stimulus)
28
what are the types of phobia
specific- of an object animal body part of a situation
social- phobia of social situation such as public speaking
agoraphobia- being outside/ public space
29
What are the behavioural characteristics of phobias
Panic- extreme fear in presence of phobic stimulus( crying, screaming, running away), children tend to freeze or have a tantrum
Avoidance- someone makes a conscious effort to prevent contact with phobic stimulus eg spending less time outside
endurance- A person chooses to stay in the presence of phobic stimulus eg spider on the ceiling
30
What are the emotional characteristics of phobias
Anxiety- phobia is an anxiety disorder, an unpleasant state of high arousal stopping a person rom relaxing or feeling positive emotion(can be long term)
fear- fear is a immediate and unpleasant response to phobic stimulus . More intense but shorter lived
unreasonable emotional response- fear/ anxiety is disproportionate to the actual threat. eg screaming at a small spider
31
What are the cognitive characteristics of phobias
selective attention- hard to look away from the stimulus. keeping attention on it is best wat to react if there is a threat (natural response) but not useful if fear is irrational.
irrational beliefs- may have unfounded thoughts in relation to phobic stimulus . eg if you blush people thing you weak no basis behind it
cognitive distortion- unrealistic perception of the phobia
32
What is depression
mental health disorder characterised by low mood or low energy levels
33
Categories of depression
major depressive disorder- short term but severe
persistent depressive disorder- long term recurring depression
disruptive mood dysregulation disorder- childhood temper tantrums
premenstrual dysphoric disorder- disruption of mood prior/ during menstruation
34
What are the behavioural characteristics of depression
Activity levels- low energy levels (lethargic) which causes withdrawal from day to day activities, in some cases it can have the opposite agitated effect(psychomotor agitation)
disruption to sleep/eating- reduced sleep(insomnia), too much(hypersomnia). changes in eating patterns results in weight lost or gained.
aggression and self harm- very irrigatable, and aggressive. (affects life). aggression can also be to self
35
What are the emotional characteristics of depression
lowered mood: someone feels sad, negative feeling of emptiness or worthlessness
anger: may experience more negative than positive emotions like anger. can be directed to self or others
lowered self esteem- how much we like ourselves reduced. some people can even get to a point where they hate themselves
36
What are the cognitive characteristics of depression
poor concentration: may be stuck with a normal task or making simple decisions. interferes with an individuals work
attending/ dwelling on the negative- pay attention to more negative aspects of life, bias toward unhappy events
absolutist thinking- thinking that situation are either good or bad(black-white thinking) a bad situation may seem as the end of the world.
37
what is OCD
condition characterised by obsession and compulsions. obsessions cognitive whilst compulsions are behavioural
38
What are the types OCD
OD- obsessions(reoccurring thoughts) or compulsions which are repetitive behaviours
trichotillomania- compulsive hair hulling
hoarding disorder - compulsive gathering possessions and inability to part with anything
excoriation disorder- compulsive skin pulling
39
What are the emotional characteristics of OCD
anxiety and distress- unpleasant experience because of strong anxiety that controls the compulsions, obsessive thoughts worrying and frightening, the urge to repeat a behaviour creates anxiety
accompanying depression- low mood and lack of enjoyment for activities compulsions bring release of anxiety
guilt/ disgust- negative emotions such as irrational guilt, minor moral issues or disgust in things such as dirt
39
What are the behavioural characteristics of OCD
Compulsions are repetitive: compelled to repeat behaviour, cleaning ordering, tidying
compulsions reduce anxiety- 10% of people with OCD have compulsions alone. Done to reduce the anxiety. eg washing hands repetitively for hygiene
avoidance- attempt to reduce anxiety and stay away from things that trigger it. eg people who are obsessed with washing their hands they are more likely to avoid germs in the first place
39
behavioural approach
a way of explaining behaviour in terms of using what is observable
39
what is the two way process model
explanation for the onset and persistence of disorders that create anxiety
39
What are the cognitive characteristics of OCD
Obsessive thoughts- 90% of people with OCD have obsessive thoughts that recur, varying with the person.
Cognitive coping strategies- people adopt coping strategies to deal with obsessions eg praying or meditating to help manage the anxiety
insight into excessive anxiety- they are aware that the compulsions are not rational. If they believed it was real it would be a different mental order all together. but they still tend to have these thoughts and scenarios as if they were real
40
Behavioural approach to treating phobias
40
operant conditioning
behaviour is maintained and shaped by consequences. positive and negative reinforcement
40
classical conditioning
learning by association. when two stimuli are paired. unconditioned stimulus(UCS) and new neutral stimulus(NS), neutral stimulus then produces same response as unconditioned stimulus alone
40
who proposed the two way process model
Orval Hobart mower(1960) classical and operant conditioning
41
Acquisition by classical conditioning
association of something we have no fear of (neutral stimulus NS) with something that triggers a fear response(unconditioned stimulus)
42
Little Albert study what else triggered distress
Other things that seemed similar to the rat eg fur coat, non white rabbit
43
Little Albert study
John Watson and Rosaline Rayner(1920). Albert had no anxiety at the beginning of the study. When a white rat was presented to him he tried to play with it. but to create a phobia Watson made a banging sound whenever the rat was presented. The noise(unconditioned stimulus) creates an unconditioned response(UCR). When the rat (neutral stimulus NS) are encountered close together they become associated to produce a fear response. The rat is now a conditioned stimulus (CS)for albert and produces a conditioned response(CR).
44
Operant conditioning
Responses from classical conditioning disappear over time, but can be maintained by operant. Done when a behaviour is reinforced or punished. reinforcements increases behaviour frequency for positive and negative reinforcement.
45
What is positive/negative reinforcement
negative is when an individual avoids a situation that is unpleasant, avoiding the phobic stimuli and the relief causes a reduction in fear but reinforces the behaviour and the phobia is maintained. Positive is when an individual is rewarded for doing a certain behaviour.
46
Evaluation
47
Real-world application
Strength is real-world application in exposure therapies
main idea of 2 way process model is that phobias maintained by avoidance
explains why it is important to be in the presence of the phobic stimuli
when avoidance is stopped the reinforcement declines and phobia cured
identifies a means of treating phobias
47
Phobias& traumatic experiences
a strength evidence for link between bad experiences & phobias
little albert shows how frightening experiences link to phobic stimulus
Ad De Jongh et all 73% of people with fear of dental treatment have had a traumatic experience
control group with no fear only had 21% with traumatic experience
confirms association between stimulus and unconditioned response
48
Cognitive aspects of phobias
Limitation of 2 way process model it doesn't account for conductive aspects
geared to explain behaviour
phobias are not simply avoidance responses( large cognitive component) eg irrational beliefs.
doesnt completely explain two process model
49
What is systematic desensitisation
behavioural therapy used to reduce unwanted response such as anxiety. hierarchy of things that cause anxiety and teaching a person to relax in these situations
50
What is flooding
someone is exposed to extreme form of phobic stimulus to reduce anxiety triggered by stimulus
51
Systematic desensitisation
behavioural therapy to gradually reduce phobic anxiety using classical conditioning. new response to stimulus is learned(counterconditioning)
1. anxiety hierarchy put together(order of phobic stimulus) from least to most frightening
2. relaxation, tries to make patient as calm as possible. impossible to be relaxed and afraid one inhibits the other (Reciprocal inhibition) eg meditation
3.Exposure whilst in relaxed state over several sessions the client is released into the presence of the phobic stimulus starting with the bottom of the hierarchy. As the client becomes more calm in these situations they are then moved up the hierarchy
52
Flooding
doesn't have a gradual build up the person is straight away released into the phobic stimulus eg spider crawling over you
the client quickly learns the the phobia is harmless( called extinction). Learned response is extinguished when the conditioned stimulus is encountered without the unconditioned stimulus. No fear response produced, relaxation in phobic stimulus because they are exhausted from their own fear response
Not unethical but the client needs to give consent as it can be traumatic
53
People with learning disabilities
strength is that it is useful for people with learning disabilities
people with requirement for treatment of phobias have learning disabilities. Alternates to SD aren't suitable eg cognitive therapy
so it is most valuable for those with disabilities
54
Evaluation
EVIDENCE OF EFFECTIVENESS
Evidence(SD)
strength is that is has evidence
Lisa Gilroy et all(2003) 42 people who had phobia for spiders and were put in 3 45 min sessions. after 33 months the SD group were less fearful than control group that were treated without exposure
concluded SD is effective for specific phobia and social phobia and agoraphobia
55
Cost effective(flooding)
Highly cost effective, it is effective at tackling symptoms
Cost effective effective and not expensive
Can work in one session compared to 10 for SD longer sessions of flooding are most cost effective
56
Traumatic
Limitation is that it is highly unpleasant
can provoke tremendous anxiety
Sarah Schumacher et al 2015 found that participants and therapists found flooding more stressful than SD. Raises ethical issue as it is causing patients stress but they do have informed consent. Higher dropout(attrition rates)
therapists may avoid using it as much as possible
57
What is the cognitive approach
mental processes, so this appraoch is to do with how our mental processes affect out behaviour
58
What is the negative triad
Beck proposed 3 kinds of negative thinking that controbute to depression: negative views of self, futur and then the world . Lead people to interpret their experiences in a negative way
59
What is the ABC model
Ellis proposed that depression occurs be an activiating event (A) that causes irrational belifs(B) that turn into a consequences
60
what is faulty information processing
The idea that depressed people tend to look more toward the negative aspects of life instead of the good in a black-and-white manner.
61
What is a negative self schema
Schema is a package of ideas and information develiped through experience, acts as a framework for interpretation of sensory information. self schema is how people see themselves. negative self schema is the idea that they interpret information about themselves in a negative way
62
explain the negative triad
neg view of the world: idea that the world is a cold place and there is no hope
negative view of the future: economy isnt going to get better, results in hopelessness and even giving up
negative view of self- " i am a failure" , enhance already negative thinking by conforming to already existing negative thoughts
63
Explain the ABC model
ellis proposed that good mental health is made up of rational thinking and mental health problems are caused by irrational thoughts
Activating event: irration thoughts triggered by external events or negative experiences eg breaking up
beliefs: belief that we must always succed is called musturbation, utopianism is the idea tht life is supposed to be fair
consequences:emotional/ behavioural consequences such as depresion
64
Evalutation
65
Reasearch support negative triad
strength is existence of supportive reaserach
cognitive vulnrability is a way of thinking that may lead to them being depressed in the future.
David CLark & Aaron Beck 1999 concluded that these cognitive vulnerabilties were common in depressed peopled. Association between cognitive vulnerability and depression
66
what other research support is there for the cognitive vulnerability
Cohen et al(2019) 473 adolescents measured their cognitive vulunterability, those that showed this vulnerability were later predicted depression
67
Real world application
strength, application in screening and treatment for depression.
Cohen et al concluded that assesing cognitive vulnerability allows psychologists to screen young people and see who is most at risk to developing depression. Can also be applied to CBT(cognitive behavioural therapy) Work by alterining cognitions that make people vulnerable to depression making them less vulnerable to negative life events
understanding cognitive vulnerability is more useful than one aspect of clinical practice
68
Real world application
A strength of Ellis ABC model is real world application.
used in rational emotive behaviour therapy (REBT) arguing with a depressed person to alter irrational beliefs that make them sad. REBT has evidence David et al 2018 it can change negative beliefs and relieve symptoms real world value
69
Reactive and endogenous depression
One limiation is that it only explains reactive depression and not endogenois. Usally a trigger or activating event but some cases are less obvious where the depression stems from ( endogenous) . can only explain some cases so it is a partial explaination
70
What is CBT
method for treating mental health disorder. Aims to deal with thinking and challenging negative thoughts can use behavioural technqiues such as behavioural activation
71
what are irrational thoughts
thoughts that are likely to interfere with a persons happiness which can lead to mental health disorders
72
What are the two elements of CBT
cognitive element: client works with patient to evaluate the actual problems and identify goals they plan to achieve also done to identify irrational thoughts
behaviour element: putting more effective behaviours in place
73
CBT
Identifies negative thoughts about future self and world, then must be challenged.
also helps clients test reality of their negative beliefs, might set homeworks. Client acts as a scientist investigating realtity of their negative beliefs. Then in the future the scientist can use the evidence against them to dispute negative thoughts
74
Elllis rational emotive behaviour therapy
ABCDE d meaning dispute and e meaning effect. Identify and dispute irrational thougts.
Eg chaning thoughts about utopianism through vigorous arguing to break the link between negative life events
75
what is empirical disputing
to see whether there is actual evidence to support the negative beliefs
76
what is logical disputing
disputing wheter the negative thoughts logically follows from facts
77
what is behavioural activation
when someone gets depressed they tend to become more isolated which maintains the symptoms. The goal of behavioural activism is to decrease the isolation and increase engagement with activities that have been shown to increase mood
78
Evaluation for effectiveness
strength for CBT is large amount of evidence supporting its effectiveness
John March et al 2007 compared CBT to antidepressants and a combiation to 327 adolescents. 81% of CBT group, 81% of antidepressant group and 86% of the both group significantly improved showing CBT is just as effective as a treatment to antipressants
Usally short 6-12 sessions and it is cost effective
can be used in public health care systems
79
Sustainability for a diveristy of clients
A limitation of CBT is that it has a lack of effectiveness for extremely severe cases & learning disabilities. In some cases people cannot motivate themselves to work with the therapist . people with disabilities my struggle to focus and complex thinking may also be difficult.
(Peter surrey suggests that general psychotherapy(talking) isn't suitable for people with mental health issues
only appropriate for specific people
80
what is the biological approach
emphasises importance of physical processes in the body such as genetic inheritance and neural function
81
Genetic explanations
genes make up chromosomes in which consists of DNA that cods for our physical features. transmitted through offspring
82
Neural explanations
physical and psychological characteristics are determined by the behaviour of our nervous system and the brain
83
Aubrey Lewis genetic explanation study
(1936) observed his patients 37% had parents with OCD and 21% had siblings with OCD suggests OCD runs in the family passed from generations
84
what is the diathesis stress model
some genes leave people more likely to develop a mental health disorder, environment stress necessary to trigger this condition though
85
candidate genes
genes that create vulnerability to OCD, some are to do with regulating serotonin development.
86
candidate gene example
5HT1-D beta is implicated in serotonin transport across synapse
87
OCD is polygenic
caused by a combination of genes working together to bring about vulnerability.
88
Polygenetic evidence
Steven Taylor(2013) analysed previous studies and found around 230 different genes are involved in OCD, genes that are related to action of dopamine as well as serotonin both neurotransmitters pay a role in regulating mood
89
what are the types of OCD
group of genes that causes OCD in one person may cause another disorder in another(aetiologically heterogenous).
90
role of serotonin
regulates mood, also responsible for relaying information from one neuron to another
low serotonin causes transmission of mood relevant information to be affected
91
Decision making systems
hoarding disorder seem to be to do with impaired faction on frontal lobes of the brain which control decision making. left parahippocampal gyrus for controlling unpleasant emotions functions abnormally
92
Evaluation
93
Research support
strength for genetic explanation is that there is strong evidence
Twin studies Gerald Nestadt et al(2010) reviewed twins and found 68% of identical twins shared OCD compared to 31% of non identical twins. Family studies, a person with another family member with OCD is 4x more likely to get OCD themselves
strong genetic influence of development of OCD
94
Environmental risk factors
A limitation of genetic model of OCD is environmental risk factors
not entirely genetic origin environmental factors also increase risk of OCD.
Kiara Cromer et al (200&0 found half the OCD clients in the sample experienced traumatic events in their past more severe OCD had more traumatic experiences
95
Research support(neural model)
strength evidence supporting it
antidepressants are used purely serotonin to reduce OCD symptoms. OCD symptoms for part of conditions that are known for biological origin like Parkinson's disease(degenerative brain disorder) if biological processes underlie OCD it suggests that biological factors are responsible for OCD.
96
No unique neural system
A limitation of the neural model is that serotonin-OCD link isn't unique to only OCD
many people with OCD also have depression(co-morbidity). Depression probably caused by disruption of serotonin action. could be that serotonin activity is disrupted in many people with OCD because they are also depressed. Serotonin may have no relevance to OCD
97
what is drug therapy
treatment involving drugs, that have an effect on the brain or part of the body. For psychological disorders these drugs have an effect on neurotransmitter levels
98
What are SSRI
type of antidepressant selective serotonin reuptake inhibitor. Serotonin released by certain neurons in the brain released by presynaptic neurons and travel across synapses
99
How do SSRIS work
Neurotransmitter conveys a signal from presynaptic neuron to postsynaptic neuron then it is reabsorbed by the presynaptic neuron where it is broken down and reused. SSRI stop the reuptake of serotonin in the presynaptic neuron and continue to stimulate post synaptic neuron
100
what average dosage of SSRI(fluxetine)
20mg can be increased
101
Combining treatments
Also used alongside CBT. drugs used to reduce emotional symptoms so they can engage with CBT. Depends on the person and how well they respond
102
Alternatives to SSRI
Tricyclics- sometimes used(clomipramine) acts on various systems but in serotonin system it has same effects as SSRI but it has side effects so generally used as a last resort
SNRI- recently used to treat OCD, increase levels of serotonin as well as other transmitter noradrenaline
103
Evaluation
104
Evidence of effectiveness
strength of drug treatment is the evidence for effectiveness. clear evidence SSRI reduce quality of life for people with OCD. Mustafa Soomro et al(2009) reviewed 17 studies and compared SSRIs to placebos.
people with SSRI showed better outcomes than placebo conditions 70% reduction for people taking SSRIs and 30% can be helped with alterative methods
105
Cost effective/ non disruptive
they are cheap compared to psychological treatments as it is very easy to make the tablets and much easier to take than a long therapy session. Good value for public health care systems eg NHS. Non disruptive to peoples lives take until symptoms decline
106
Serious side effects
some people have no benefit
side effects such as indigestion, blurred vision of loss of sex drive temporary for most people but for the minority can last a while. tricyclic clomipramine has more serious side effects. 1 in 10 have erection problems and weight gain whilst 1 in 100 have aggressive heart related problems
reduces quality of life and may also deter them from taking it all together.
