A second criticism is that many patients with SZ are Psychological explanations of schizophrenia estranged from their families or have minimal contact, and yet there is no evidence that such people are less prone to relapse. This suggests that there is a scientifically proven link between faulty processing, and high dopamine levels.
So, due to faulty processing, the simple problem of mistaking something unreal for something real has lead eventually to paranoia. 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.
This theory therefore suggests that the home environment Psychological explanations of schizophrenia the relationships a child has with their parents through messages plays a role in the development of SZ. This is because of individual differences, and the fact that as most of the memories were from childhood, you cannot go back in time to assess the validity of the recollections.
Instead it builds on the biological model, and offers an explanation on how the problems can develop into schizophrenia.
This means that the child will become confused as the message they are given is conflicting, as one message effectively invalidates the other.
He found that SZ patients reported a higher recall of double bind statements conflicting messages by their mothers than non SZ patients. Also, the families are studied retrospectively, meaning they are studied long after the mental disorder may have affected the family system.
This is partly because the theory is based upon abstract ideas such as dreams and the subconscious. A strength of this theory is the supporting evidence from Berger. 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.
Another criticism of the Double Bind theory is the inability to replicate the findings across studies. This was supported by Linszen who found this to be four times more likely. 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.
There is also support for this explanation from Vaughn and Leff who also found that the level of expressed emotion had an affect on relapse rates amongst discharged patients. The aim of this machine is show schizophrenics that their hallucinations are not real.
According to the different psychological explanations of SZ this is because of the high emotional tension and the many secrets and close alliances that are kept in the family.
This supports the connection between the biological and cognitive explanations. Therefore this leads to confusion and eventual withdrawal.
As a result, the child is left with self doubt and eventual withdrawal. For example, Meyer and Lindenberg found a link between excess dopamine in the prefrontal cortex, and the state of working memory.
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.
The psychodynamic explanation Freud believed that schizophrenia is caused by issues in the sub-conscious mind of the schizophrenic. This study suggests that the more time a SZ patient spends with a family with high levels of EE means that they are more likely to relapse.
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. This is because living with someone with SZ is difficult and distressing for all the family as it has an impact on everyone, not just the patient of SZ.
Type 1 symptoms Positive Symptoms and Type 2 Negative symptoms. 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.
There has also been an argument as to whether the EE model is a cause or an effect of SZ. On the other hand, this study has not been replicated therefore the validity of their results is questioned.
Evaluation of the cognitive explanation of schizophrenia There is a wealth of research evidence to back up the cognitive explanation. Therefore it is unclear whether there is an impact. It is said to occur within men when they are 25 or younger, however it occurs at an older age of for women.
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 so 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 the symptoms; delusions, grandeur etc.
For example, Brown found that patients who returned to homes where there was a high level of expressed emotion, for example lots of hostility, criticism and over involvement, they showed a greater tendency to relapse in comparison to those who returned to homes where there was a lower level of expressed emotion.Psychological explanations.
