| Abstract: | Delusions have for a long time been regarded as one of the major signs of mental disorder. Above all else they are cognitive phenomena in that they purport to express ideas about the world or the self. Despite this it is only relatively recently that the ideas and methods of cognitive psychology have been used in the study of delusions, at least in any systematic way. This paper reviews the work carried out so far, which is starting to yield some consistent trends. These include an excessively self-seeking bias in judgments made by people with delusions and a tendency to make judgments on the basis of rather less evidence than controls. |
