Outline and evaluate psychological explanations of schizophrenia Essay
? Describe and assess psychological details of schizophrenia (24 marks) Brown and Birley analyzed stressful existence events inside the role of relapse in schizophrenics.
That they found that 50% of folks experience an annoyinh life function e. g. death, romance break-up, job loss etc . in the 23 days prior to a schizophrenic episode. A control test reported a decreased and predetermined level of stressful life situations over the same period. Nevertheless not all facts supports the role of life events. For example , Vehicle Os et al reported that people were not very likely to have a significant stressful your life event in the 3 months earlier the start their health issues.
In a possible part of the research, those people who had knowledgeable a major lifestyle event proceeded to have a reduce likelihood of urge, further-more life events following your onset of schizophrenia may be a result rather than a cause of schizophrenia. Bateson et al (1956) recommended that children who often receive contradictory messages from other parents are very likely to develop schizophrenia e. g. a mother hugs her child then again disapprovingly tells him off for being clingy. This is known as the double-bind theory.
There is facts to support the double-bind theory. Berger identified that schizophrenics reported a better recall of double-bind claims by their moms than non-schizophrenics. However this evidence may not be reliable, because patients recall may be troubled by their schizophrenic. Other research are less supportive. Liem assessed patterns of parental sales and marketing communications in families of schizophrenic children and found zero difference in comparison to normal children.
Expressed emotion (EE) involves high degrees of negative sentiment (e. g. criticism) or perhaps high degrees of positive emotion (e. g. over-protectiveness). Linszen at al (1997) found the patient returning to a household with large EE is four occasions more likely to relapse than a sufferer returning to a family group with low EE. There may be an issue since the if EE can be described as cause or perhaps an effect of schizophrenia.
Hogarty et approach found that such remedy can substantially reduce involvement was the main factor of the remedy or if other areas of family treatment may have got helped. Cognitive psychologists feel that disturbed considering processes will be the cause of schizophrenia. It is thought that all the components that work in usual brains filtering and procedure information happen to be defective in the brains of folks with schizophrenia.
People with schizophrenia have no filtration system so they will let in irrelevant information, that they are unable to interpret correctly. Research have shown that people with schizophrenia are poor at laboratory tasks which in turn require taking note of only a few stimuli. On the other hand this theory doesn’t seriously explain what causes schizophrenia more than just the indications of the disorder. Hemsley (1993) suggested the central deflect in schizophrenia is the break down in the marriage between previously stored memories and fresh incoming information. People with schizophrenic cannot switch on their schemas so are very subjective to sensory overload , nor know which in turn aspects of a predicament to attend and which to ignore.
There is promising research with family pets offering support for Helmsley’s ideas. Frith (1992) advised that people with schizophrenia cannot distinguish between activities that are due to external makes and those going on internally. This individual believes that individuals with schizophrenic have the lack of ability to generate required action, the inability to monitor willed action and the inability to keep an eye on the intentions of others.
Frith suggests that these processes happen to be part of meta representation’ that permits us know about our desired goals and be familiar with belief of others. Friths theory has presented a comprehensive construction for describing the indications of schizophrenia. Nevertheless , the theory remains regarded as speculative.
