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.

    ABSTRACT: The objective of this study was to examine the article production on psychosis from the main spanish journals of psychology and psychiatry, as well as to make comparisons among them. 16 journals of psychology and 5 of psychiatry were selected and a period of revision of four years settled down (2003-2006). The sample was constituted by 183 articles. For the comparison of the journals four index were used: proportion of articles on psychosis in relation to the total of generated articles; used type of methodology; used type of sample; and aspect of the psychosis in whose investigation it is centered. The results show that little is investigated, that most of the studies is theoretical or ex- post facto, that more the frequently studied subjects are those with psychosis and that the taken care of aspects more are related to the etiology and the treatment of the disease.
