21) Delusions in schizophrenia are often polythematic. Can the two-factory theory of delusional beliefs be applied to the delusions in schizophrenia? a) Definitely not because there is no single impairment that could suggest the content of polythematic delusional beliefs. b) Possibly with hallucinations, overactive pattern recognition, and misperception of internally generated content as being external all being possible factor 1 impairments c) Possibly because there is often evidence of dorsolateral prefrontal cortex dysfunction in schizophrenia d) Definitely not because polythematic delusions would require multiple impairments to explain factor 2. e) Definitely not because factor 1 always has to be a neuropsychological impairment.
