12.3.3 Cognitive Explanations

Cognitive explanation

Cognitive explanation -The symptoms of schizophrenia are caused by dysfunctional thought processing.

Types of dysfunctional thought processing:

Impaired meta-representation: Being unable to recognise actions and thoughts as your own. This can lead to positive symptoms of schizophrenia such as auditory hallucinations by hearing voices, and delusions such as thought insertion.
Impaired central control: Being unable to suppress automatic thoughts and speech triggered by other thoughts. Can help to explain disorganised speech and the development of thoughts as each word triggers associations which can't be suppressed.
