We evaluated predictions derived from the ultradian theory of hypnosis regarding the effects of temperature, light, trance length, and time of day on reported trance depth in 95 college undergraduates. Temperature and light showed no relation to trance depth. However, as predicted by ultradian theory, subjects who were kept in trance for 15 minutes reported greater trance depth than those who experienced a 5-minute trance. Time of day interacted with subjects' self-reported time of peak alertness in the following way: Subjects who reported greatest alertness in the morning achieved greater trance depth in the morning than in the evening, whereas those subjects who reported greater evening alertness reported deeper trance in the evening than in the morning. This latter finding was inconsistent with ultradian theory and prior research. Alternative explanations for this finding are discussed. Overall, the results from the present study do not provide strong support for Rossi's ultradian theory of hypnosis.
我们评估了源于催眠超日节律理论的预测，该理论涉及温度、光线、恍惚时长以及一天中的时间对95名大学生报告的恍惚深度的影响。温度和光线与恍惚深度无关。然而，正如超日节律理论所预测的那样，处于恍惚状态15分钟的受试者报告的恍惚深度比经历5分钟恍惚的受试者更深。一天中的时间与受试者自我报告的警觉高峰时间相互作用，具体如下：早上报告警觉性最高的受试者，早上的恍惚深度比晚上更深；而那些报告晚上警觉性更高的受试者，晚上的恍惚深度比早上更深。后一个发现与超日节律理论和先前的研究不一致。本文讨论了这一发现的其他解释。总体而言，本研究结果并未为罗西的催眠超日节律理论提供有力支持。
