Hallucinations occur along a continuum of normal functioning. Investigating the factors related to this experience in nonclinical individuals may offer important information for understanding the etiology of hallucinations in psychiatric populations. In this study we test the relationship between psychosis proneness, loneliness, and auditory hallucinations in a nonclinical sample using the White Christmas paradigm. Seventy-six undergraduate students participated in this study. We found that slightly more than half of our participants endorsed a hallucinatory experience during the White Christmas paradigm. However, we did not observe a relationship between the number of hallucinatory experiences and schizotypy, propensity to hallucinate, or loneliness. Moreover, there were no differences on these measures between individuals who reported hearing a hallucination during the White Christmas paradigm relative to those who did not. Thus, there may be other contextual factors not investigated in this study that might clarify the mechanism by which auditory hallucinations are experienced in a nonclinical population.
幻觉是正常功能的连续体的一部分。研究非临床个体中与这种体验相关的因素，可能为理解精神病患者群体中幻觉的病因提供重要信息。在这项研究中，我们使用白色圣诞节范式测试了非临床样本中精神病倾向、孤独感和听觉幻觉之间的关系。76 名大学生参与了这项研究。我们发现，我们的参与者中有略多于一半的人在白色圣诞节范式中报告了幻觉体验。然而，我们没有观察到幻觉体验的数量与精神分裂症倾向、产生幻觉的倾向或孤独感之间存在关系。此外，在白色圣诞节范式中报告听到幻觉的个体与没有报告听到幻觉的个体在这些测量指标上没有差异。因此，可能还有其他在这项研究中未被调查的情境因素，可以阐明非临床人群中听觉幻觉的体验机制。
