cognitive explanation for schiz

Question 1

dysfunctional thinking

Answer 1

frith et al identified 2 types of dysfunctional thought processing:
- metarepresentation
- central control

• unable to filter preconscious thoughts and gives too much though to info that woud be filtered = overloads the mind = positive symptoms

Question 2

define metarepresentation

Answer 2

• the ability to reflect on thoughts and behaviours = allows us insights into our own intentions and goals
• ## failure to recognise actions and thoughts as being your own = beleif that someone else is controlling them = auditory hallucinations

Question 3

define central control

Answer 3

• schiz paitents expreience derailment of thoughts because each word triggers associations which cant be supressed = disorganised speech
• inable to supress and override automatic actions and speech = urge to open a door

Question 4

ao3 - research support

Answer 4

• stirling et al = compared the performance on a range of cognitive tasks with 30 people with and without schiz
• stroop task = name the font colours of colour words = supress the tendency to read the words aloud
• friths cental control theory = people with schiz took longer

Question 5

ao3 - only a proximal explanantion

Answer 5

• are proximal explanations because they explain what is happening right now to produce symptoms = cant explain what causes the condition such as genetics and family dysfunction
• unclear how genetic and childhood trauma may lead to problems with metarepresentation or central control
