psychopathology/abnormality
TRANSCRIPT
Definitions
Deviating from socialnorms
Deviating from ideal mental health
Failure to function
Strengths Distinction between desirable and undesirable behaviour. Social roles are considered as helpful to living together
Behaving not according to what is desirable, but what is according to a mental health prone attitudes is a positive way to recognise normality from abnormality
The person in need has the first saying, perspective of an individualsexperiencing abnormality becomes the judge of personal behaviour
Weaknesses •Susceptible to abuse•Cultural relativism•Deviance is related to context and degree•Eccentric and abnormal•Changes in time
•Who can achieve this•Cultural relativism•Changes over time•Subjective criteria •Difficulty of self-actualizing, not everyone achieves their full potential
•Not the whole picture-just determining the extent of a persons problems•Cultural relativism•Exceptions to the rule – Everyone is different, doesn't meant their abnormal
Description Expected way of behaving in society

Biological approaches to psychopathology
Biological approaches to psychopathology
Genetics
Some people are genetically at risk of developing a mental disorder
There is strong evidence relating to mental disorders such as bipolar, depression and schizophrenia
Schizophrenia; a first degree relative e.g- son or daughter, of someone suffering the disorder has a 10% chance of also developing it whereas the general population only have a 1% chance
Gottesman – meta analysis of 40 twin studies, found a concordance rate for schizophrenia of 48% in monozygotic twins and a 17% in dizygotic twins
Heston –did an adoption study. Used 47 adopted children who's mothers had schizophrenia and 50 adopted children who's mothers did not have it. 5 children from the first group also got schizophrenia whereas 0 children from the second group got it.
Neurotransmitters
Dopamine
Too much of this causes schizophrenia and an imbalance of levels in the neurotransmitter can explain the onset of schizophrenia
Biological approaches to psychopathology
Serotonin
Too little of this can cause depression and an imbalance of these can explain the mental disorder of depression
Noradrenaline
Too little of this neurotransmitter is linked to anxiety disorders such as phobias and an imbalance of noradrenaline can cause the onset of phobias
Infection
Bacteria viruses can cause physical and psychological conditions such as syphilis and influenza virus
Syphilis bacteria causes STI’s which causes general paresis: forgetfulness, mental deterioration and delusions
Influenza virus in pregnant women, this exposes the foetus to the virus which then lies in the child's brain causing schizophrenia
Infection explains psychopathology (mental disorders) as a result of syphilis or influenza
Biological approaches to psychopathology
Strengths
Techniques have shown that there are biological component's
Research shows there could be a genetic link
Drugs can work as treatment options
It is scientific
Weaknesses
Reductionist
Genetics don’t provide a complete explanation
Drugs don’t work for everyone
Focuses on curing symptoms not the actual cause

The psychodynamic approach
Psychopathology
The psychodynamic approach Psychopathology
Conscious thoughts Conscious – Something you can think about where you are fully aware
of everything around us Preconscious - Something that we have stored in our memories that is
about something in the past and can bring back to the conscious mind Unconscious – A place in our mind where we store shameful
experiences, sexual desires, fears and violent motives, we do not have access to this mind. Issues form childhood can be stored in the unconscious mind. We do not have access to the mind. Access comes in the form of dreams or slip of the tongue. The unconscious mind could lead to distress because the person does not understand why it is that they think this way
Freud's personality theory ID Pleasure principal, present at birth Wants everything now Money, food and sex No morals
Superego The conscience which as morals Develops at the age 5
Ego Develops at the age of 3 Decides between ID or the superego Reality principle
The psychodynamic approach Psychopathology
Cause of abnormality
In childhood, the ego is not developed enough to deal with traumas so these events re repressed
In order to balance the demands it employs a defence mechanisms to protect themselves such as denial, projection, regression or repression
Strengths
The psychodynamic model reminds us that experiences in childhood can effect us throughout our lives
No need for medication
Weaknesses
Cannot scientifically test it, its just a theory
Evidence is through a therapist which causes bias and misinterpretation
Retrospective data, looking back on data
Lack of evidence
Sexism, Freud focused his research on men or boys

The behavioural approach to
psychopathology
The behavioural approach to psychopathology
Abnormal behaviour is learnt through conditioning or social learning, for example, classical and operant conditioning
Classical conditioning; unconditioned stimulus has an unconditioned response. When the conditioned stimulus is combined with an unconditioned stimulus, it creates and unconditioned response. Therefore the conditioned stimulus becomes the conditioned response.
Operant conditioning is where you learn through reinforcement, this could be through a reward and being rewarded for doing something good, right or well and/or through a punishment, for punishing behaviour which is not good or right.
Social learning theory
Imitation of role models and reinforcement can also lead to abnormal behaviour
Modelling – coping the behaviour of role models
Attention; noticing the behaviour
Retention; remembering the behaviour
Motor reproduction; it has to be psychically possible
Motivation; has to be a reason why they want to copy
The behavioural approach to psychopathology
Albert Bondura – bobo doll Studying the effects of observation of a model on subsequent
behaviour
It was suggested that watching aggressive behaviour might diffuse the inner aggression of the watcher
After the child watched the adult play around hitting the doll, the child copied and did similar things
Variations:
1) Aggression was rewarded (Vicarious reinforcement)
2) Aggression was punished (Vicarious punishment)
3) Adult neither rewarded nor punished (No reinforcement)
The results found that when the child was rewarded behaviour was most likely to be copied
When it was punished, behaviour was least likely to be copied
Strengths Behaviour approaches when combined with cognitive approach have
proved to be effective in treating clients with phobias and neurotic disorders (OCD)
Weaknesses
Only behaviour is considered, the thoughts and feelings f cognition are not taken into account
Symptoms not cause, limited view (reductionist)

Cognitive approach to psychopathology
Cognitive approach to psychopathology
Ellis’ ABC model: A – activating events
B – beliefs are affected
C – consequences of the thoughts
These result in rational and irrational beliefs
The cognitive model assumes that thinking expectations and attitudes result in mental illness
Becks cognitive triad: Having a negative view of the self
Having a negative view of the world
Having a negative view of the future
Strengths: Concentrates on current thought processes which means a patients
remembers in more detail
Cognitive and behavioural therapies when mixed together have a high success rate
Weaknesses: Focusing only on a persons cognition may be too narrow
Situational factors
Consequence not cause
Not all irrational beliefs are actually irrational
Biological therapies
Drugs:Anti-anxiety drugs (BZ’s)
Reduce tension and anxiety
Enhance action of GABA -> reduction of brain activity -> calm
Side effects can include: drowsiness, fatigue and weight gain
Anti-depressive drugs
Increase levels of serotonin
SSRI (e.g. Prozac) interferes with re-absorption of serotonin
Side effects can include: dizziness, dry mouth and nausea]
Anti-psychotic drugs (Neuoleptics)
Decrease in the production of neurotransmitter dopamine
Relieves hallucinations
Close supervision is needed
Side effects can include: Weight gain, constipation, dizziness and nausea
Evaluation of drugsStrengths:
Effectiveness – WHO reported that relapse rates after one year of using placebo drugs for schizophrenic patients was 55%
Ease of use – chemotherapy requires little effort of the user
Biological therapies
Weaknesses:
Placebo effects – Patients who receive placebos found it almost as effective as those receiving the real drug
Tackles symptom rather than problem
Side effects – SSRI’s cause anxiety , sexual dysfunction, insomnia, nausea etc.
Addiction – BZ’s should be limited to only taking them for 4 weeks because they become very addictive
ECT – Electroconvulsive therapy
This therapy is used when drugs fail to treat depressive disorders
22,000 peoples receive this treatment per year
Patient is given a muscle relaxant as a 110mv shock in passed through the brain causing a seizure
The therapy increases a neurotransmitter which increases a patients mood
The therapy can cause brain damage or substantial memory loss
Usually given 3 times a week and the patient will require 3-15 treatments
Biological therapies
Evaluation of ECT
Strengths:
Effective treatment for depression
Can be life saving to patients who are suicidal
60%-70% 0f patients improve after therapy
Weaknesses:
84% of patients relapse after 6 months
Huge side effects including: Impaired memory, cardiovascular changes, irregular heartbeat, headaches and anxiety
When a placebo ECT was done and was compared with a real ECT. The results were that those who did the placebo ECT recovered almost as well as the patients from the real one

Psychological therapies
Psychological therapies
Psychoanalysis
Free association:
A client is asked to express anything which comes into mind which could extend back to childhood
The therapist will only interfere occasionally perhaps to encourage some reflection on a particular experience
The therapist will then try to interpret what the client has said and try to draw conclusions
Freud believes that these associations are determined by unconscious factors which analysis tries to uncover
Dream analysis:
Freud felt that during dreams are the barrier into the unconscious mind
The therapist will analyse the patients dream and might be able to identify significant conflicts repressed into the unconscious mind
The meaning of the dream can only be revealed by therapist interpretation
The therapist and client will then analyse the dream together resolving the source of the anxieties
Psychological therapies
Evaluation of psychoanalysis
Strengths:
Effectiveness – 80% of patients benefit from psychoanalysis compared to 65% of electric therapies
Length – The longer the treatment, the more beneficial patients found it and psychoanalysis can last years
Weaknesses:
False memories – Some therapists are not helping patients to recover repressed memories but are planting ‘False memories’
Appropriateness - Fails to appreciate the differences between individuals
Psychological therapies
Systematic desensitisation
Used to treat phobias
Extinguishes undesirable behaviour by replacing it with a more desirable one; relaxation
The client will work out a hierarchy of fear from least to most frightening about their phobia
The client works through each stage of the hierarchy starting with the least frightening, becoming relaxed with that stage and then moving up
Example of spiders:
Think about spider
See a picture of a spider
Be in the same room as a glass tank with a spider in
Sit next to the tank with lid shut
Sit next to the tank with lid open
Put hand in the tank
Hold the spider
Strengths:
Appropriateness – quick and require little effort
Effectiveness – successful for a range of anxiety disorders as 75% of patients with phobias respond well to SD
Weaknesses:
Symptom substitution – SD may appear to resolve the problem but they only elimate or supress symptoms
Reduced effectiveness – some suggest that SD may not be as effective in treating some anxiety problems; fear of heights or animals
Psychological therapies
Rational-emotive behaviour therapy Helps patients understand irrationality and consequences of this
way of thinking
REBT helps a person substitute these thoughts with a more effective problem-solving method
Challenging irrational beliefs Client and therapist decide how the clients beliefs can be reality
tested
The aim is for the client to become more self-sufficient and recognise the consequences of their faulty cognitions
The client and therapist will then set new goals for the client in order to become more realistic
Because it is not activating events themselves it can cause unproductive consequences therefore the patient is encouraged to dispute these beliefs by:
Logical disputing – Self-deflating beliefs do not follow logically from the information available (Does this information make sense?)
Empirical disputing – Self-deflating beliefs may not be consistent with reality (Where is the proof that this is accurate?)
Pragmatic disputing – Emphasises the lack of usefulness of self-deflating beliefs (How is this belief likely to help me?)
Psychological therapies
ABC model and REBT
A (activating event) B (belief about event) C (emotional consequences) D (disputations take place) E (effective beliefs replace irrational ones)
Strengths
Effectiveness – It is an effective treatment for a number of different types of disorders
Appropriateness – It is useful for clinical population (mental disorders) and non-clinical populations (anxiety)
Weaknesses
Irrational environments – REBT cannot control outside factors such as marriage, bullying or jobs etc and as a result, these environments reinforce these irrational beliefs
Not suitable for all – REBT does not always work for everyone and is not always what everyone wants, some just don’t want the advice that a therapist will have to offer
