This theory therefore suggests that the home environment and the relationships a child has with their parents through messages plays a role in the development of SZ.
His explanation, the Double Bind theory, states that SZ can occur due to conflicting messages given from parents to their children, for example when a parent expresses care but does Psychological explanations for schizophrenia in a critical way.
Type 2 symptoms however show more catatonic behaviour, for example a loss of drive, a lack of emotion or catatonic stupor. This childlike state is what brings about Psychological explanations for schizophrenia symptoms; delusions, grandeur etc.
The cognitive explanation This explanation says the schizophrenia is caused by faulty thought processing.
Type 1 characteristics include things such as delusions, hallucinations and paranoia. The EE model has becoming widely accepted that research is now focussing on relatives of those with SZ in order to understand better which aspects of high and low EE relate to relapse.
They found a higher prevalence of expressed emotion was one of the main causes of relapse, as there is a lot of negativity in the families which in the end leads to high levels of stress which they find it very difficult to cope with. Therefore there are other aspects of intervention that could be useful as it is unclear as to whether EE is helping the family as a unit.
However they also studied the amount of face to face contact patients spent with relatives after discharge, and they found an increase in relapse rates as face to face contact increased, and even more so with higher levels of expressed emotion.
Overall, an excellent piece of work as always, X. This suggests that there is a scientifically proven link between faulty processing, and high dopamine levels. Overall, it was concluded by Lopez that families characterised by negative affect criticism has much higher relapse rates in comparison to those with positive affect warmth.
As a result, the child is left with self doubt and eventual withdrawal. It is said to occur within men when they are 25 or younger, however it occurs at an older age of for women. This is partly because the theory is based upon abstract ideas such as dreams and the subconscious.
For example, Yellowlees et al created a machine that creates virtual hallucinations, the sort that a schizophrenic might experience.
Instead it builds on the biological model, and offers an explanation on how the problems can develop into schizophrenia. This is because there is no clear template of a loving relationship; instead the child is always unsure if they have done something wrong due to the conflicting messages they are given.
A second criticism is that many patients with SZ are either estranged from their families or have minimal contact, and yet there is no evidence that such people are less prone to relapse. By suggesting that a parent has caused SZ is at least unhelpful and at most highly destructive, as they not only have to cope with living with someone with SZ, but they are then told that it is their fault, which will lead them to feel guilty and hurt as they are blamed for a poor upbringing.
One psychological explanation of SZ was put forward by Bateson et al who looked at childhood as a base for developing SZ, for example the interactions children have with their mothers.
If someone experiences something particularly harsh they may regress to a childlike state, before the ego was fully formed. An additional criticism is the fact that the Hawthorne Effect may have occurred.
For example, Meyer and Lindenberg found a link between excess dopamine in the prefrontal cortex, and the state of working memory. This is also because negative emotion will most likely be found in many different cultures.
This study suggests that the more time a SZ patient spends with a family with high levels Psychological explanations for schizophrenia EE means that they are more likely to relapse. There are said to be problems as it is called a retrospective recall, as the data is unreliable.
A final criticism is that it is said to be an unconstructive theory as the theory blames the parents and families for a child developing SZ. A strength of this theory is the supporting evidence from Berger. Therefore it is unclear whether there is an impact.
Whilst there is little evidence that this will work, it has only been possible because of the cognitive explanation. As it was an observation of the families, there is no proof that the parents will act as they normally do around their families, therefore the validity of the results reduces as the results will not show a true picture of how they really are as a parent.
He found that SZ patients reported a higher recall of double bind statements conflicting messages by their mothers than non SZ patients.Start studying Psychological explanations of schizophrenia. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Psychological explanations of schizophrenia. Psychological theories Psychodynamic Freud () believed that schizophrenia was the result of two related processes, regression to a preego state and attempts to re-establish ego control. The characteristics of Schizophrenia (SZ) can be categorised into two different types: Type 1 symptoms (Positive Symptoms) and Type 2 (Negative symptoms).
