Psychological Explanations: Cognitive Flashcards
Cognitive explanations focus on
The role of mental processes in schizophrenia
Specifically the symptoms are said to result from
Dysfunctional thought processing
Ie sufferers process information in a different “abnormal way” compared to non sufferers
Frith identified several kinds of dysfunctional thought processing that may explain some symptoms
may explain some symptoms
Meta representation
Cognitive ability that allows us to have
Insight into our own intentions. A dysfunction impairs the ability to recognise ones thoughts as coming from oneself (external thoughts)
Auditory hallucinations
Delusions of control
Central control
The cognitive ability to supress
Automatic responses so that one can perform deliberate ones instead
A dysfunction impairs ability to supress, speech can be triggered by other thoughts
Disorganised speech
The supervisory attention system
Is a cognitive system that
Enables us to generate self initiated action
A dysfunction impairs ability to imitate goal directed action eg starting a conversation, bathing or doing some work
Negative symptoms
Avolition
Supporting evidence for role of dysfunctional thought processing in positive symptoms from Allen
Compared schiz experiencing auditory hallucinations with a control group on a task that required them to listen to pre recorded speech and identify their own or that of others
Hallucination group made more errors than the control
Increases validity of cognitive explanations showing auditory hallucinations linked to dysfunction in meta representation
Problems establishing causality
Can account for current symptoms but can’t explain origins of the condition ie what caused sufferers to develop dysfunctional thought processing in the first place
Evidence fails to establish cause and effect, unclear whether cognitive factors are the cause of the symptoms or whether dysfunctions are the results of having symptoms (underlying biological abnormalities)
Reduces validity of cognitive explanations, may not be the ultimate cause of disorder
