What are the 4 definitions of abnormality
Statistical Infrequency
Deviation from social norms
Failure to function adequately
Deviation from ideal mental health
What is statistical Infrequency
Defined by what falls outside the statistical range
Common traits and behaviours are normal, uncommon traits aren’t
E.g. those with an IQ below 70 can be diagnosed with intellectual disability
What are the limitations to statistical infrequency
An uncommon behaviour isn’t necessarily an abnormal one
e.g. an IQ over 130 is just as uncommon as under 70 but we wouldn’t consider it abnormal.
Not all disorders are uncommon
The lifetime prevalence of depression is around 20% - however people with statistically common psychological disorders are still in need of treatment
What is Deviation from social norms
A behaviour which goes against the standards of behaviour set by a society
E.g. Pseudobulbar affect (PBA) is characterised by intense and uncontrollable displays of emotion - may be disproportionate
What are the limitations of Deviation from social norms
Social norms may vary across time and across cultures
E.g. Hearing voices is seen as highly abnormal in Western society, but in some cultures, such as the Maori people of New Zealand, is it seen as a normal thing
Many people engage in behaviours which are not strictly in line with social norms, but there aren’t psychologically abnormal
What is deviation from ideal mental health
It argues that mental ill health is the failure to achieve good mental heath
Good mental health consists of (according to Marie Jahoda - 1985):
Positive self attitudes
Autonomy, personal growth and self actualisation
Integration of all the peoples processes and attributes
The ability to cope with stress
Sense of reality
The ability to introspect
Environmental mastery
Absence of mental illness
What are the limitations of deviation from ideal mental health
Do you have to satisfy all of the criteria to be considered abnormal
Do you have to satisfy the criteria at all times
Are these criteria still appropriate today
Many only apply to certain societies (western)
What is failure to function adequately
Cannot cope with day-to-day existence
David Rosenhan and Martin Seligman defined it as:
When a person no longer conforms to standard interpersonal rules, for example maintaining eye contact and respecting personal space.
When a person experiences severe personal distress
When a person's behaviour becomes irrational or dangerous to themselves or others
Positives: it represents a sensible threshold for when people need professional help so treatment and services can be targeted to those who need them most.
What are the limitations of Failure to function adequately
It is easy to label non-standard lifestyle choices as abnormal
E.g. Not having a job or permanent address might seem like failing to function, however people with alternative lifestyles choose to live ‘off-grid’
Similarly those who favour high-risk leisure activities or unusual spiritual practices could be classed as irrational and perhaps a danger to self.
Which risks limiting people’s freedom
What are the behavioural characteristics of phobias
Avoidance - effort to stay away from phobic stimulus
Panic in the presence of the stimulus
Endurance - staying near phobic stimulus and experiencing high levels of fear
What are the emotional characteristics of phobias
Anxiety - The sufferer will feel anxious whenever they are reminded of the phobic stimulus. Phobias are classed as anxiety disorders
Fear - Sufferer will experience intense disproportionate fear when in the direct presence of the phobic stimulus
Emotional response is unreasonable - the anxiety/fear that they will feel will be disproportionate to any threat posed
What are the cognitive characteristics of phobias
Selective attention - The individuals attention will be drawn to the stimulus
Irrational beliefs - The individual will hold irrational beliefs about the danger posed. The sufferer will likely know their beliefs are irrational
Cognitive distortions - Their perceptions may be inaccurate and unrealistic
What are the behaviourist approaches to explaining phobias
They suggest that people are a product of their experiences
And that they learn phobias through the two process model introduced by Mower (1960):
Classical conditioning
Operant conditioning
What is classical conditioning
Involves learning to associate something of which we initially have no fear (neutral stimulus) with something that already triggers a fear response (unconditioned stimulus)
Explain the case study linked to classical conditioning
Little Albert Case Study completed by John Watson and Rosalie Rayner (1920) In which they were attempting to give him a phobia.
Albert was presented with a Neutral Stimulus of a white rat amongst other animals that he originally had no fear of
Whenever Albert attempted to touch the rat, researches made a loud noise which frightens Albert
This was an UnConditioned Stimulus which made an UnConditioned Response of fear.
The NS became associated with the UCS which meant they both produced a fear response
Even with the UCS removed the NS produced fear on its own meaning the NS became a Conditioned Stimulus which produced a Conditioned Response
The conditioned then generalised to similar objects such as a fur coat
What is operant conditioning
The idea that we can increase or decrease certain behaviour by introducing consequences.
How does operant conditioning apply to phobias
Mowrer believed that operant conditioning is what caused phobias to be long lasting.
He suggested that when a phobic stimulus is avoided and we successfully escape the fear and anxiety, the reduction in fear [that we feel] reinforces the avoidance behaviour which maintains the phobia.
What are some limitations of the behavioural method to explaining phobias
Not all phobias are caused by trauma
DiNardo (1988) found that conditioning events like dog bites are common in participants with dog phobias (56%) but they are equally common in participants without dog phobias (66%)
Menzies and Clarke (2003) examined 50 cases of children with water phobia.
Only 1 of the 50 parents could recall a traumatic experience involving water, and 28 claimed their child was always afraid of water, even on their first encounter.
Seligman (1970) proposed the idea of biological preparedness
This is the idea that there are certain things it would be adaptive for us to be afraid of such as snakes and heights
Modern humans still have this genetic predisposition which is why these phobias are uncommon
The failure to account for biological preparedness means it is an incomplete explanation
What are the real world applications of the behavioural approach to explaining phobias
Has led to the development of 2 successful treatments:
Systematic desensitisation
Flooding
These are both forms of exposure therapy which:
counteracts avoidance behaviour
Which means they don’t experience the anxiety reduction that encouraged avoidance
Which decreases avoidance
If these methods (which are based on behavioural ideas) are effective then it validates the behavioural approach
Name 3 emotional features of depression
Sadness
Anger
Worthlessness
Guilt
Hollow/empty
Anxiety
Dyregulation - Can’t regulate emotion
Name the behavioural features of depression (6)
Self-isolation
Difficulty looking after oneself
Procrastination
Anhedonia - lack of pleasure
Sleep disturbance
Substance use
What are the cognitive features of depression (2)
Executive dysfunction - unable to make decisions
Suicidal thoughts
What does the cognitive approach to explaining depression suggest
It suggests that depression may be the result of faulty thinking
What are the cognitive approches to explaining depression
Aaron Becks Cognitive theory of depression (1967)
Albert Ellis’s ABC model (1962)
What is Becks cognitive theory of depression
Faulty information processing
Negative self-schemas
The negative triad
What is faulty information processing
Focusing on the negatives of a situation instead of the positives, even if the situation is a good one
Blowing small problems out of proportion
Thinking in black and white terms
What is a negative self-schema
Schema = package of ideas and information developed through experience
Beck linked this with childhood trauma - it leads to people developing a negative self-schema (sense of self)
If something unfortunate happens to me its my fault because I’m stupid
What is becks negative triad
A person develops a dysfunctional view of themselves because of three interconnected types of thinking - which happen automatically
Negative view of self
Negative view of the world
Negative view of the future
Repeated intrusive thoughts of this nature can lead to depression
What is Ellis’s ABC model
He developed this model to explain how some people react differently to events, and how different reactions may lead to depression
Activating event:
According to Ellis, we get depressed when we experience negative events and these trigger irrational beliefs
Beliefs
Consequences
When an activating event triggers irrational beliefs there are emotional and behavioural consequences. For example, if you believe you must always succeed then fail at something, this can trigger depression
What are the strengths of the cognitive approach to explaining depression
Grazioli & Terry (2000s):
Assessed 65 Women’s tendance to think negatively while pregnant
Assessed the same Women’s level of post-natal depression after birth
They found that negative thinking while pregnant predicted worse depression after birth
Real world application:
If depression is caused by irrational negative thinking, it would suggest we should treat depression by changing the way patients think about
CBT aims to do that
What are the limitions of the cognitive approach to explaining depression
Neurochemistry is an alternative explanation to depression
Neurotransmitters are used by neurons to communicate
Monoamines are a group of neurotransmitters involved in depression
Serotonin: Help to regulate emotions, calm and sleep
Dopamine: reward, motivation, movement
Noradrenaline: Increases alertness and focus
Low levels of these can result in depressed mood, worthlessness/guilt and fatigue
Doesn’t explain all aspects of depression:
Some depressed patients are deeply angry and beck cannot easily explain this extreme emotion.
What is cognitive behaviour therapy
The cognitive treatment for depression
As the cause of depression is negative thoughts, the aim of CBT is to challenge these thoughts
Has been praised for targeting the root cause of the symptoms rather than just masking symptoms
What are the steps in CBT
Identifying irrational thoughts
Disrupting irrational thoughts
Patient as a scientist & homework
Behavioural activation
What is identifying irrational thoughts
Client and therapist work together to identify the nature of the irrational thoughts of the client
Also helps the client to gain an insight into their thought processes
What is disrupting irrational thoughts
Once identified, the therapist will aim to disrupt the irrational thoughts via:
Logical Arguments: Arguing based on whether the clients thoughts actually make sense
Empirical Arguments: Arguing based on actual evidence
What is patient as a scientist & homework (include behavioural activation)
The client is required to objectively assess the validity of their irrational thoughts just as a scientist would
This is done via diary keeping of their experiences, such as their interactions with others
Behavioural activation:
The client will be encouraged to continue going out and doing things they usually enjoy
The more the client goes out and does things, the more opportunities there are for positive events and interactions occur
These can be used as evidence against irrational thoughts
What are the strengths of CBT
Research evidence: March et al (2007)
Comparison between CBT and antidepressants
Assessed treatment response after 36 weeks in 387 adolescents
Those that used CBT: 81% improved
Those that used antidepressants: 81% improved
Combination of the two: 86% improved
Shows CBT is effective, although more effective with antidepressants
Targets route cause - lower relapse rate
Validifies experiences
Take skills you learn into the future
Doesn’t have side effects like nausea, dependency, irritability and sexual disfunction
Negative patient experience with a high drop out rate
Has a lower drop out rate than anti-depressants
What are the limitations of CBT
Antidepressants better:
Removes blame from the patient
Easy - less time invested
CBT may not work for more severe cases
Requires a high level of motivation and engagement from the client
Those with sever depression may find this difficult - so for them CBT will be ineffective
May refer to use antidepressants to stabilise their mood and then use CBT
Overly focused on cognition:
May ignore circumstantial issues
Many with depression may be facing real external issues such as poverty, debt or bullying
For these, it may be that their mental health is extricably linked to their circumstances
CBT may not change their circumstances but it may help them cope better
What are the behavioural characteristics of OCD
Compulsions:
Repetitive
Simply to reduce anxiety. ~10% of sufferers show compulsive behaviour without any obsessions
Avoidance: may avoid things that will trigger anxiety - eg. Germaphobes will avoid germs
What are the emotional characteristics of OCD
Anxiety and distress - compulsions create anxiety
Accompanying depression -
Guilt and disgust
