Schizophrenia biological and sociocultural explanations
Summarised mind map on the subtypes, biological explanations (genetics, dopamine & enlarged ventricles) and socio-cultural explanations (double-bind, labelling & expressed emotion) with some A02 points
Hope it's useful!

- BIOLOGICAL EXPLANATION
- GENETICS
- Gottesmen and Shield
- MZ: 48% DZ:17%, One parent: 6%,
- Should be 100% suggesting other factors must be involved
- MZ: 48% DZ:17%, One parent: 6%,
- Heshon
- Group 2 - bio mum doesn't have S
- Gottesmen and Shield
- ENLARGED VENTRICLES
- Lieberman, proposed that enlarged ventricles
could explain S as they cause damage to the brain
- Associated with -ive symptoms
- Weydant
- Used advanced scanning techniques to show enlarged ventricles in brains of S
- Good scientific evidence
- Used advanced scanning techniques to show enlarged ventricles in brains of S
- Lieberman, proposed that enlarged ventricles
could explain S as they cause damage to the brain
- DOPAMINE
- iverson
- Post mortem studies found people with S, had hgher levels of dopamine than people without S
- Death could have caused higher levels of dopaminee
- Post mortem studies found people with S, had hgher levels of dopamine than people without S
- iverson
- GENETICS
- SOCIO-CULTURAL EXPLANATION
- LABELLING
- Theory denies any existence of illness and so offers no treatment
- SHEFF - believes that when a person is labelled with s,, this then inluences how socitey treats this person & so affects their behaviour
- ROSENHAN
- 8 healthy people make appointments
- All 8 diagnosed with S, once institutionalised acted normal
- Average stay was 19 days - in remission
- Unethical (misleads health professionals)
- Ignores bio explanation evidence
- Shows how a label is hard to change
- Unethical (misleads health professionals)
- Average stay was 19 days - in remission
- All 8 diagnosed with S, once institutionalised acted normal
- 8 healthy people make appointments
- EXPRESSED EMOTION
- Families with high show hostility, high disapproval, not tolerant of behaviour & very critical
- more likely to lead to relapse as patient feels trapped
- & like an outsider due to excessive attention

- Genetics does play a role in S
- Multifactoral: S is caused by several genes in chromosomes 1, 2, 5 & 11, which supports genetic explanation

- LABELLING
- DOUBLE-BIND
- Child is placed in a “no-win” situation by one or both parents. This situation is where the child will be told or given one thing but another action will conflict and contradict the first action.
- Batesons double bind theory was neveer followed up by research
- Child doesn't know how to respond and is dependent on the mother so cannot leave.

- A mothers tells her child that she loves him but turns away in disgust
- Child doesn't know how to respond and is dependent on the mother so cannot leave.
- Can explain how -ive symptoms develop
- Cannot explain how +ive symptoms develop
- Batesons double bind theory was neveer followed up by research
- Lacks empirical evidence
- Hostility - neg attitdue as family feels the patient is choosing not to get better & that the disorder is controllable
- Nomura et al
- When a patient does relapse, they are back in the highly active phase of schizophrenia
- Family therapy which aims at reducing EE results in lower relapse rates
