先前的研究（如Moller & Husby, 2000; Blackwood et al., 2004）表明，妄想思维伴随着对自我和被认为与自我相关的刺激的过分关注。目的是检查那些亚临床妄想意识高的人是否表现出更高的自我参照倾向。采用混合设计，将健康个体在彼得斯量表上分为高分组和低分组。妄想量表（Peters, Day, & Garety, 1996）在三个实验中对日常推理任务进行了比较。与低pdi组相比，高pdi得分者对日常论点的自我参照的反对意见比他人参照的反对意见更强烈，并且对日常论点提出了更多基于自我参照的断言的反对意见。这些发现支持了这样一种观点，即亚临床妄想与自我参照偏差有关，这在人们形成或评估自己的信念时所进行的日常思考中很明显，这可能有助于妄想的形成。
Previous studies (e.g. Moller & Husby, 2000; Blackwood et al., 2004) have revealed that delusional thinking is accompanied by an exaggerated focus upon the self and upon stimuli that are perceived to be related to the self. The objective was to examine whether those high in subclinical delusional ideation exhibit a heightened tendency for self-reference. Using a mixed design, healthy individuals, classified into high- and low-scoring groups on the Peters et al. Delusions Inventory (Peters, Day, & Garety, 1996), were compared on everyday reasoning tasks across three experiments. High-PDI scorers, in contrast to the low-PDI group, rated self-referent objections to everyday arguments as stronger than other-referent objections and formulated more self-referent assertion-based objections to everyday arguments. The findings support the notion that subclinical delusional ideation is linked to a self-reference bias, which is evident in the sort of everyday thinking that people engage in when forming or evaluating their beliefs and which may contribute to delusion formation.
