Dysfunctional Thought Processes (psychological) Flashcards
What did Frith (1992) state?
- cognitive factors are associated with the development of schizophrenia
- symptoms like delusions and auditory halluncinations might occur bc of issues with self-monitoring
- cannot track own thoughts properly
- claim thoughts are ‘not their own’
What is metarepresentation?
- the ability for a person to reflect on thoughts and experiences
What are the three factors of metarepresentation?
Inability to:
- generate voluntary action
- mointor voluntary action
- mointor the beliefs and intentions of others
What did Frith say about schizophrenic patients?
- they are unable to distinguish between actions brought internally or externally
What reserach did Frith (1970) conduct?
- gave sz and healthy participants a two choice task
- they had to guess the colour of the next card as either red (R) or black (B)
- sz participants produced stereotypical choices like RRRRRRRR or RBRBRBRB
- healthy participants produced random choices like RRBRBRBRBBB
What did Frith’s results suggest?
- schizophrenic patients’ have problems generating immediate actions
- supports the idea that they have a lack of self-control which is caused by cognitive impairments
Evaluate Frith’s study.
(+) shows how positive symptoms develop. Cognitive approach highlights why hallucinations and delusions develop bc of metarepresentations
(+) reserach for cognitive model is conducted as lab experiments - highly controlled, scientific, objective.
(-) reductionist
(-) doesn’t account for negative symptoms like speech poverty anf avolition
(-) cause and effect
(-) doesn’t explain what causes sz only a list of developed symptoms
What did Hemsley (1993) state?
- healthy people have a good combination of perception and memory but sz patients don’t
- recognised that sz patients have a breakdown between stored information (schemas) in LTM and new information/data
- sz patients cannot access schemas
- sz patients experience sensory overload (cannot choose what to focus on) -> disorganised thinking
Evaluate Hemsley’s (1993) theory.
(+) Stirling (2006) support evidence of sz patients processing information differently to healthy people. 30 sz, 18 control. Sz took 2x longer to name colours.
(+)/(-) nature or nuture debate. Dysfunctional thinking caused by environment/upbringing. Or because of biological reasons.
(-) ethical issues need to be considered. Unable to give fully informed consent/withdraw.
(-) doesn’t explain cause of sz only how dysfunctional thoughts lead to symptom development.
(-) Beck and Rector focused on a complex interaction of neurobiological, environmental, behavioural, and cognitive causes of sz. Found that abnormalities in brain can cause sz, leading to dysfunctional thinking.
