This study is a replication of the experiment by Lange, Houran, Harte, and Havens (1996 on contextual variables, in which hallucinations appear to be affected by the environmental context. These contextual variables are influential in the reporting of haunting and poltergeist-like episodes. This study extended the previous study by adding new factors of time of day, climactic conditions, and emotional feelings. These were analyzed for a different sample, looking for further congruency between experiential content and the context. The sample (N=8431 were reports found on the Internet and in one book. The Lange, et al. study was replicated in that contextual variables were identified in 99.2% of the reports, the content of the reports was judged to be consistent with the nature of the contextual variables in 58.8% of the reports, and contextual variables were related to the percipients' state of arousal and the modalities of experience.
本研究是对兰格、胡兰、哈特和黑文斯（1996年）关于情境变量实验的复制，在该实验中，幻觉似乎受环境情境影响。这些情境变量在闹鬼和类似吵闹鬼事件的报告中具有影响力。本研究通过增加一天中的时间、气候条件和情绪感受等新因素扩展了先前的研究。针对不同样本对这些因素进行了分析，以寻找体验内容与情境之间的进一步一致性。样本（N = 8431）是在互联网上和一本书中找到的报告。兰格等人的研究得到了复制，即99.2%的报告中识别出了情境变量，58.8%的报告内容被判定与情境变量的性质一致，并且情境变量与感知者的唤醒状态和体验方式相关。
