Two factor theory of monothematic delusions essay

Types The delusions that fall under this category are: For example, a person may believe that they are in fact not in the hospital to which they were admitted, but in an identical-looking hospital in a different part of the country. Note that some of these delusions are sometimes grouped under the umbrella term of delusional misidentification syndrome.

Causes Current cognitive neuropsychology research points toward a two-factor approach to the cause of monothematic delusions. For example of one of these first factors, several studies point toward Capgras delusion being the result of a disorder of the affect component of face perception.

As a result, while the person can recognize their spouse or other close relation they do not feel the typical emotional reaction and thus the spouse does not seem like the person they once knew.

As studies have shown, these neurological defects are not enough on their own to cause delusional thinking. An additional second factor, a bias or impairment of the belief formation cognitive process is required to solidify and maintain the delusion. Since we do not currently have a solid cognitive model of the belief formation process, this second factor is still somewhat of an unknown.

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.

Additionally, studies [4] have shown that they are more prone to making errors due to matching bias—indicative of a tendency to try and confirm the rule.

These two judgment biases help explain how delusion-prone people could grasp onto extreme delusions and be very resistant to change.

Researchers claim this is enough to explain the delusional thinking. However, other researchers still argue that these biases are not enough to explain why they remain completely impervious to evidence over time.Patients with delusions secondary to neurological damage often have lesions in right frontal cortex but, according to two factor theories, the theme of the belief is conferred by damage to a second structure; for example the fusiform face area in Capgras delusion.
