psychological explanation for SZ Flashcards
what is family dysfunction?
- explanation that suggests it is the interpersonal relationships within the family that result in symptoms
the schizophrenogenic mother
- psychodynamic theory
- people with SZ gets their paranoid delusions as a result of cold rejecting and controlling mother but a passive father
- she creates an atmosphere of stress, tension and secrecy
- triggers psychotic thinking
what is the double blind theory
- the child is experiencing mixed messages of what is wanted from them
- unable to do the correct thing
- Bateson suggests this is a result of disorganised thinking and paranoia
what is expressed emotion
- verbal interactions the caregiver has with the person with SZ
- exaggerated involvement: indicating the sufferer is a burden via self sacrifice
- criticism and control: of sufferers behaviour
- hostility: physical, verbal or emotional rejection
Evaluation of study: supports expressed emotion does affect people with SZ
- Butzlaf + Hooley meta analysed 27 studies
- relapse into SZ is more likely In families that involve issues w/ expressed emotion
Evaluation of study: supports those in dysfunctional families are more likely to develop SZ
- Tienari studied biological children of SZ mothers
- 5.8% adopted in psychologically healthy families= sz
- 36.8% adopted into dysfunctional families = sz
- interpersonal family environment has an impact on having SZ
what is the cognitive explanation for sz
- sz based on assumption that the ability to process thoughts are dysfunctional
what is firth’s attention deficit theory ?
- sz due to faulty attention system
- unable to process preconscious thought
- gives too much attention to info that would usually be filtered= overloading the mind
- accounts for positive symptoms= hallucinations/delusions
Firth’s theory on central control
- unable to over ride automatic actions and speech to make purposeful actions and achieve goals
- delusions= difficulty to explain reasons for something
- speech derailment= inability to resist expressing automatic thoughts
what is meta-representation
- ability to identify your own thoughts and actions by paying attention to them
- faults in this system result in delusions e.g. thoughts/actions controlled by outside thoughts
Evaluation: Firths support with biological neuroscience
- 30 sz w/ various symptoms had PET scans
- those with negative symptoms had reduced blood flow to the frontal cortex
- showed increased activity in an area of the temporal lobe responsible for retrieving memories
- biological differences in sz associated with cognitive processes
Evaluation: intervention can be given to help
- family therapy reduces expressed emotions in families
- effective intervention and supports dysfunctional family argument
Evaluation: Stirlings stroop test
- 30 sz patients and 18 control
- named ink colours on words without naming the word
- desire to say word needs to be controlled
- sz patients took twice as long than controls
- sz patients have dysfunctional thought processing
Evaluation: CBT as intervention
- CBT as effective treatment
- indicates cognitive factors are involved
Evaluation: socially sensitive explanation
- socially sensitive to suggest that sz is caused by the family
- parents already dealing with difficulty of families behaviour
- adding more stress and anxiety by making the family think they’re responsible
Evaluation: impossible to find cause + effect
- could be the sz of the individual and their behaviour that causes family dysfunction
Evaluation: there is lots of evidence to show that sz is biological
- cant ignore it could have a biological cause e.g. genetics/ neurotransmitters
- family dysfunction could act as a trigger
- but basic cause is biological
