引言：在本文中，我们提出并捍卫一个混合理论的发展妄想，结合了中心思想的两个有影响力的（但有时激烈反对）理论方法的错觉-双因素理论和预测误差理论。方法：在介绍了双因素理论和预测误差理论的中心思想，我们描述了我们的和解项目的动机，解释我们提出的混合理论的理论细节，并回答潜在的反对我们的建议。结果：根据我们提出的混合理论，妄想的第一个因素是身体上的异常预测错误，而第二个因素在物理上基于对异常预测误差的精度的过高估计。针对预期的反对意见，我们认为，混合理论是内部一致的，它构成了一个真正的混合之间的双因素理论和预测误差theory.Conclusion：一个和解之间的双因素理论和预测误差理论是可能的和可取的。特别是，我们的混合理论提供了一个简约和统一的错觉，无论是单主题或多主题，在各种各样的医疗条件。
Introduction:In this paper we present and defend a hybrid theory of the development of delusions that incorporates the central ideas of two influential (yet sometimes bitterly opposing) theoretical approaches to delusions—the two-factor theory and the prediction error theory.Method:After introducing the central ideas of the two-factor theory and the prediction error theory, we describe the motivations for our conciliatory project, explain the theoretical details of the hybrid theory we propose, and answer potential objections to our proposal.Results:According to the hybrid theory we advance, the first factor of a delusion is physically grounded in an abnormal prediction error, and the second factor is physically grounded in the overestimation of the precision of the abnormal prediction error. Against anticipated objections, we argue that the hybrid theory is internally coherent, and that it constitutes a genuine hybrid between the two-factor theory and the prediction error theory.Conclusion:A rapprochement between the two-factor theory and the prediction error theory is both possible and desirable. In particular, our hybrid theory provides a parsimonious and unified account of delusions, whether monothematic or polythematic, across a wide variety of medical conditions.
