Psychopathology Flashcards
Definition of abnormality
Something that differs from the norm.
Statistical deviation/ infrequency
> Behaviour that is statistically rare should be seen as abnormalities.
Any individual who falls outside of the ‘normal distribution’ are perceived as being abnormal.
Strengths: statistical deviation/infrequency
> Clearly appropriate for many mental illnesses where by statistical criteria is available eg. intellectual disability disorder.
All assessments with patients with mental disorders includes some kind of measurement of how severe their symptoms are compared to statistical norms.
Allows for an objective, value-free assessment of the level of mental disability being experienced
Limitations: statistical deviation/ infrequency
> Not all infrequent behaviours are abnormal - some rare behaviours and characteristics are desirable
Not all abnormal behaviours are infrequent as some statistically ‘frequent’ behaviours are ‘abnormal. For example
The cut-off point is subjectively determined as there needs to be a decision about where to separate normality and abnormality.
Deviation from social norms
> Each society has norms for what is seen as acceptable behaviour. any behaviour that varies from these norms may be seen as abnormal. the definition draws a line between socially desirable and undesirable behaviours.
Those who do not adhere to what society deems as acceptable in that community or society are labelled as abnormal.
Strengths of ‘deviation from social norms’
One strength of this definition is that it allows the consideration of the social dimensions of a behaviour. this means it allows for our understanding that a behaviour may be normal in one situation but not another.
Limitations of ‘deviation from social norms’
Many individuals regularly break social norms but they are defined as ‘eccentric’ rather than mentally ill. norms change over time, this means that we cannot truly define any certain act as ‘abnormal’ because as norms change so must our beliefs about what constitutes ‘abnormal’ behaviour.
Failure to function adequately
This definition perceives individuals as abnormal when their behaviour suggests they cannot cope with everyday life. the behaviour is considered abnormal when it causes distress leading to dysfunction, for example, disrupting the ability to work.
Rosenhan and Seligman seven features of abnormality (failure to function adequately)
- suffering
- maladaptiveness (danger to self)
- vividness and unconventionality (stands out)
- unpredictably and loss of control
- irrationality/ incomprehensibility
- causes observer discomfort
- violates moral/social standards
Strengths: ‘failure to function adequately’
It takes into consideration the experiences of the patient allowing an assessment to be made from the point of view of the person experiencing it. this is relatively easy to judge objectively through an assessment of criteria (WHODAS) the more symptoms the sufferer shows, the more abnormal they are
Limitations: ‘failure to function adequately’
abnormality is not always accompanied by dysfunction; for example psychopaths can commit murder and still appear normal
Deviation from ideal mental health
Perceives mental abnormality in a similar way to the perception of physical health. Looks for an absence of well being. eg. depression: The symptoms of this disorder illustrates the definition: sufferers generally have low self-esteem, they can struggle to make decisions, they experience high levels of stress concerning their low mood condition.
Deviation from ideal mental health: Jahoda.
Rather than identifying what is abnormal, Jahoda identified six characteristics of what is to be normal and an absence of these characteristics indicates abnormality. The more of the criteria an individual fails to meet, the further away from normality they are. the six characteristics are; positive attitude towards self, self-actualisation, resistance to stress, autonomy, accurate perception of reality and, mastery of the environment.
Strengths: ‘deviation from ideal mental health’
It takes a positive approach to mental problems. The focus is on what is desirable (for example, working towards being autonomous) rather than what is undesirable (for example focusing a patient on the amount of distress they feel).
Limitations: ‘deviation from ideal mental health’
> This definition has been accused of having over demanding criteria - at any given moment most people do not meet all the ideals so in effect we are all ‘abnormal’ for example, few people experience ‘personal growth’ all the time!
Furthermore, the criteria is difficult to measure. jahoda argued mental health can be considered like physical health but diagnosing mental health is far more subjective in the absence of X rays etc.
Dsm: diagnostic and statistical manual of mental disorders
There are a number of systems for classifying and diagnosing mental health problems the best known of these is the dsm. the dsm is updated every so often as ideas about abnormality change. the current version is in its 5th edition (dsm- 5) – this was published in 2013.
Phobias
Defined as ‘a persistent and unreasonable fear of a particular object, activity or situation’ - (comer 2008). Highlights that almost anything can become a phobia. An intense, persistent, irrational fear a particular object, event or situation. the response is disproportionate and leads to avoidance of phobic object, event or situation. Fear is severe enough to interfere with everyday life.
Phobias: dsm
The dsm recognises the following categories of phobias:
> Specific phobias
> Social phobias
> Agoraphobia, of public crowded places (not open spaces), of leaving safety of home.
Phobias: signs and symptoms
> Behavioural: how a person acts (behaves) around the feared object or situation which is likely to be varying states of panic leading to avoidance.
Emotional: how a person feels when experiencing anxiety
Cognitive: how a person thinks about phobic stimuli
Phobias: key characteristics
The key characteristics of phobias are that they are extreme fears, which are disproportionate to the actual danger, and lead to avoidance of the object or situation.
Phobias: behavioural characteristics
> Panic in response to the phobic stimulus such as crying, screaming, running away. Children react by freezing, clinging or having a tantrum.
Avoidance- unless the sufferer is making a conscious effort to face their fear, often go out of their way to avoid having to come into contact with the phobia stimulus. Can make it hard to go about daily life.
Endurance- This is the opposite of avoidance in which the sufferer remains in the presence of the phobic stimulus but continues to experience high levels of anxiety.
Phobias: emotional characteristics
> Anxiety - phobias are often classed as anxiety disorders. They involve an emotional response of anxiety or fear - makes it hard for the sufferer to experience any positive emotion. Anxiety can be long term, fear is the immediate and unpleasant response we experience when we encounter the phobic stimulus.
Emotional responses are unreasonable: The emotional responses we experience in relation to phobic stimuli go beyond what is reasonable.
Phobias: cognitive responses
> Selective attention to the stimulus- If a sufferer can see the phobic stimulus it can be hard to look away from it. Keeping our attention on something dangerous can be good because it gives us a chance to respond quickly if there is a threat but it is not good if the fear is irrational.
Irrational beliefs- A phobic may hold many irrational beliefs in relation to a phobic stimuli.
Phobias: cognitive distortions
The phobics perceptions of the phobic stimuli may be distorted.
Phobias: behaviourist approach background
Founded by JB Watson, the behaviourist approach studies observed behavioural responses of humans and animals. the behaviourist approach believes we learn to behave in response to our environment, either by stimulus-response association, or as a result of reinforcement. important contributors to the behaviourist approach are Ivan Pavlov, with his theory of classical conditioning, and B.F. Skinner, and his work into operant conditioning.
Phobias: behaviourist approach classical and operant conditioning
> Classical conditioning: a basic form of learning in which a neutral stimulus is repeatedly paired with another stimulus known as the unconditioned response.
> Operant conditioning: changing a behaviour because of a reward or for avoidance. once a fear is established, the individual then avoids the object or situation that produces the fear. this in turn reduces the anxiety. it also strengthens the fear and makes it more likely that this object/situation will be avoided in the future.
Phobias: two-process model
Mowrer suggests that phobias are acquired as a result of classical conditioning and maintained by operant conditioning. A person who is terrified of spiders is likely to run away when they see one. the escape and consequent reduction of fear acts as a negative reinforcer, increasing the likelihood that they will continue to avoid spiders in future. in this way, the phobia is maintained.
