2 psychological explanations of
schizophrenia (AO1)
- Disturbed thinking
- cognitive psychologists suggest that schizophrenia
is caused by faulty thought processes
- further suggest that these faulty thought processes are
caused by abnormal brain functioning
- in neurological pathway between the
hippocampus and pre-frontal cortex - linked to
faulty regulation of dopamine in this area
- cognitive psychologists suggest that schizophrenia
is caused by faulty thought processes
- Frith - differences in conscious and pre-conscious thought
- Frith (1992)- suggests that schizophrenics have
problems filtering information between conscious
and pre-conscious processing
- conscious processing is used when we have to think and pay close attention to what we are doing
- pre-conscious processing is for tasks which are more trivial that we can do automatically without thinking
- and we can usually do a number of tasks at once
- Frith (1992)- suggests that schizophrenics have
problems filtering information between conscious
and pre-conscious processing
- How delusions and hallucinations develop
- because the filter between the 2 types of processing is
defective in schizophrenia, allows unimportant
information to reach their conscious awareness
- this information is misinterpreted as important and is how delusions are explained
- hallucinations are explained by unimportant non-speech
based sounds filtering into conscious awareness and
are experienced by schizophrenics as voices
- because the filter between the 2 types of processing is
defective in schizophrenia, allows unimportant
information to reach their conscious awareness
- Dysfunctional families and double-bind theory
- other psychological explanations suggest that schizophrenia
may result from dysfunctional family relationships
- Bateson et al - proposed the double-bind theory which
suggests that as children schizophrenics received
contradictory messages from parents
- a mother may tell the child she loves
them while her body language is rejecting
- makes the child confused as they do not know
how to respond and as a result they fail to
develop a coherent structure of reality
- this in the long run causes the
schizophrenic systems
- other psychological explanations suggest that schizophrenia
may result from dysfunctional family relationships
- Expressed emotions
- family relationships theory also suggest that the type of communication
within the family may influence relapse rates in schizophrenia
- it is proposed that high levels of expressed emotion within the family influences relapse
- a communication style that involves criticism, hostility and emotional over-involvement
- a communication style that involves criticism, hostility and emotional over-involvement
- some research has found that a patient returning to a
family with high EE are 4 times more likely to relapse
- family relationships theory also suggest that the type of communication
within the family may influence relapse rates in schizophrenia
