Psychological explanation Flashcards
What do cognitive explanations suggest?
Disturbed thinking processes are the cause not the consequence of schizophrenia.
What approach can cognitivists take regarding physiological abnormality or cognitive malfunctioning.
Physiological abnormalities lead to cognitive malfunctioning which causes schizophrenia.
What does Fritch’s cognitive deficit model suggest?
We have a deficit in the Central Monitoring System (CMS). This labels actions as done by me or external. A defect means we cannot detect if our inner voice is done by us and leads to hallucinations. We also have a faulty filtering process which means we cannot filter out irrelevant information leading to over-dramatising.
What does Shallice’s model suggest?
There are two types of actions, self-willed and external stimuli. Schiz patients have a defect in the Supervisory Attention System (SAS) and hence we are unable to generate self-willed actions.
What symptoms do Frith’s model explain? The same for Shallice.
Frith: positive.
Shallice: negative.
What would the diathesis stress model suggest is the appropriate pathway for schizophrenia for cognitivists?
Genetic vulnerability –> Biochemical abnormality –> cognitive deficits + stressful life events = schizophrenia.
What does the schizophrenogenic family model suggest?
Families with high emotional tension, many secrets, and conspiracies, particularly those with a conflict causing mother will encourage the development of psychotics symptoms.
What does the double bind theory suggest?
If children are faced with conflicting injunctions without having opportunity to respond means children will perceive all environmental stimuli as contradictory. This inability to distinguish between stimuli leads to schizophrenic symptoms.
What does the expressed emotion theory suggest?
Home with high expressed emotion are likely to encourage greater relapse rates. The three dimensions of EE are:
- Hostility
- Critical comments
- Emotional over-involvement.
How can we measure EE levels?
Using the camberwell family interviews.
What would the diathesis stress model say about high EE?
When combined with the cognitive deficits, it leads to the onset of schizophrenia.
