Schizophrenia: Cognitive Approach (IV Explanation) Flashcards
What points can be made when describing the explanation?
Explaining hallucinations
Explaining negative symptoms
Lack of preconscious filters
Comprimised theory of mind
How can hallucinations be explained?
Morrison: Triggers like sleep deprivation cause hallucinations. People hear them in maladaptive ways wich cause behaviours like social widthdrawl. The emotions this produces reinforces the voices and makes the problem worse
How can negative symptoms be explained?
Beck: He uses the idea of the cognitive triad and thinks the person endorses dysfunctional beleifs about themselves, their abaility to feel pleasure and holds a cynical world view. Their mental filters allow them to see the world in a biased way which adds to their pessimism and creates the negative symptoms
How does a lack of preconscious filters lead to schizophrenia?
Frith: The filters that inhibit sensory information don’t work so they get overwhelmed and are able to see multiple interpretations of events. This stops them being able to select and carry out an appropriate course of action. These can be to do with issues such as increased dopamine.
What is the compromised theory of mind?
Frith: People struggle to identify the source of their thoughts so think they are external
What three cognitive disorders result in the symptoms of schizophrenia?
Disorders of willed action (avolition and catatonic symptoms)
Disorders of self-monitoring (delusions and hallucinations)
Disorders of monitoring others (Delusions of persecution)
What evaluative points can be made?
Supporting research Reductionist Not comprehensive CBT Intergrated model
What is the supporting research?
Barch: Schizophrenics do slower on the stroop test as they can’t filter out the sensory information which supports the idea about lack of filters
How is the study reductionist?
It reduces a complex disorder to a single explanation
Frith: It’s the result of faulty cognitive mechanisms
Why isn’t the theory comprehensive?
Not explaining issues with movement
No explanation of the origin of the disorder
How does the sucess of CBT support the theory?
It challenges the person’s interpretation of events so helps them to become more rational
Uses the principles from the cognitive explanation
What is the intergrated model of schizophrenia?
Genes combine with life events and social stressors with affects the dopamine system. The increase in dopamine causes issues with cognitive processing
Needs to be considered in a holistic way
Who came up with the intergrated model?
Howes and Murray
