Two factor theory of monothematic delusions essay

Some research has shown that delusional people are more prone to jumping to conclusions [2] [3] [4] and thus they would be more likely to take their anomalous experience as veridical and make snap judgments based on these experiences.

Consider the Capgras delusion: Where we depart from James and Maher is in our view that the hypotheses abductively inferred from the abnormal experiences as attempted explanations of these experiences will normally be evaluated, and then rejected because of the strength of the evidence against them.

Researchers claim this is enough to explain the delusional thinking. Hope to identify such a potential cause.The neuropsychological bases of various monothematic delusions are rather well understood, and there is a well-worked-out general neuropsychological theory of monothematic delusion, the two-factor theory.
