Theories of delusions which rely on a combination of abnormal experience and defective belief evaluation and/ or cognitive bias are the subject of an emerging consensus. This paper challenges the validity of these theories and constructs a two factor alternative.
The paper starts by identifying the difficulty the current theories have explaining the complex delusions of schizophrenia and then, by considering, first, the aetiology of somatopsychotic symptoms, and second, the literature on the relationship between confabulation and allopsychotic symptoms, demonstrates that the natural solution is to retain the experiential factor whilst replacing the second factor with confabulation.
The paper is then able to demonstrate that the resultant two-factory theory can clarify recent work on the aetiological role of autonoetic agnosia and on the relationships between confabulation, delusion, and thought disorder.
The theory supersedes currently available theories in terms of its simplicity, fruitfulness, scope and conservatism and represents an advance in the search for unified theory of psychosis.
依赖异常体验与有缺陷的信念评估及/或认知偏差相结合的妄想理论正逐渐成为共识。本文对这些理论的有效性提出质疑，并构建了一种双因素替代理论。
本文首先指出当前理论在解释精神分裂症复杂妄想方面存在的困难，然后通过考虑，其一，身心症状的病因，其二，关于虚构与异己症状之间关系的文献，证明自然的解决办法是保留体验因素，同时用虚构替代第二个因素。
然后本文能够证明由此产生的双因素理论可以阐明近期关于自我认知失认症病因作用以及虚构、妄想和思维障碍之间关系的研究。
该理论在简单性、丰富性、范围和保守性方面超越了现有理论，代表了在寻求统一的精神病理论方面的一项进展。
