Which researcher proposed the schizophrenogenic mother? And what approach does it consider?
Freida-Fromm Reichmann
What does the schizophrenic mother suggests? What is the result
Suggests that those who may have grown up with a cold, controlling and rejecting mother were at more risk of developing the disorder.
As a result a climate of tense and secrecy was created which causes the person at risk to become distrustful = paranoid delusions
What is the double blind theory for schizo?
Receiving conflicting messages from family members act as risk factors for schizo. Developing children fear doing wrong, but bc they receive mixed messages from parents = wrong
This results in a withdrawal of love = view the world as confusing and dangerous.

What are the two dysfunctions proposed by the Firth et al for schizophrenia?
- Metarepresentation dysfunction
- Central control dysfunction
What is metarepresentation and how does dysfunction cause schizophrenic symptoms?
This is the ability to reflect on thoughts and behaviour. Those with schizo fail to metarepresent and therefore show symptoms of hallucinations and delusions
What is central control dysfunction and does it lead to schizophrenic symptoms?
This it the ability to suppress responses whilst performing actions. They suffer a derailment of thoughts due to word triggers which cause associations that they are unable to suppress. Symptoms that derive from this are speech poverty and thought disorder
