Teorías cognitivas de las creencias delirantes

Résumé

In this paper we present a review of current cognitive theories of delusion formation. Empirical research on delusions has shown that people with delusional beliefs do show underlying cognitive biases in several tasks which are related to the severity of their pathological beliefs. The main theories discussed in this paper, in their relation to the onset and maintenance of delusions, are related to the following domains: reasoning deficits, attentional biases, causal attributions biases, and theory of mind deficits. We defend that these studies are providing a new view of that psychotic symptom as there is an assumption that the reasoning processes implied in the formation of delusions are similar to those found in reasoning in normal people. The implications of this research both on the understanding of delusions and on innovative pathways to psychological intervention are discussed.
