人们研究了许多具有高度特异性的妄想，这些妄想可以单独出现在那些信仰完全不引人注目的人身上——“单主题妄想”，如卡普格拉妄想或科塔尔妄想。我们回顾了这些妄想，并总结了妄想信念的双因素理论，该理论试图解释是什么导致了这些妄想信念的最初产生，以及是什么阻止了它们在出现后被拒绝。虽然这些妄想可以在没有其他症状的情况下发生，但它们也可以在精神分裂症的情况下发生，当它们可能伴有其他妄想和幻觉时。我们认为，对于像Capgras和Cotard这样的特殊妄想，即使这些妄想发生在精神分裂症的背景下，而不是单独发生时，这种双因素解释仍然适用。
Numerous delusions have been studied which are highly specific and which can present in isolation in people whose beliefs are otherwise entirely unremarkable - "monothematic delusions" such as Capgras or Cotard delusions. We review such delusions and summarize our 2-factor theory of delusional belief which seeks to explain what causes these delusional beliefs to arise initially and what prevents them being rejected after they have arisen. Although these delusions can occur in the absence of other symptoms, they can also occur in the context of schizophrenia, when they are likely to be accompanied by other delusions and hallucinations. We propose that the 2-factor account of particular delusions like Capgras and Cotard still applies even when these delusions occur in the context of schizophrenia rather than occurring in isolation.
