Studying the effect of psychedelic substances on expression of creativity is a challenging problem. Our primary objective was to study the psychometric measures of creativity after a series of ayahuasca ceremonies at a time when the acute effects have subsided. The secondary objective was to investigate how entoptic phenomena emerge during expression of creativity. Forty individuals who were self-motivated participants of ayahuasca rituals in Brazil completed the visual components of the Torrance Tests of Creative Thinking before and the second day after the end of a two-week long ceremony series. Twenty-one comparison subjects who did not participate in recent psychedelic use also took the Torrance tests twice, two weeks apart. Repeated ingestion of ayahuasca in the ritual setting significantly increased the number of highly original solutions and phosphenic responses. However, participants in the ayahuasca ceremonies exhibited more phosphenic solutions already at the baseline, probably due to the fact that they had more psychedelic experiences within six months prior to the study than the comparison subjects did. This naturalistic study supports the notion that some measures of visual creativity may increase after ritual use of ayahuasca, when the acute psychoactive effects are receded. It also demonstrates an increased entoptic activity after repeated ayahuasca ingestion.
研究迷幻药物对创造力表达的影响是一个具有挑战性的问题。我们的主要目标是在急性效应消退后，研究一系列安非他命类物质致幻剂仪式后创造力的心理测量学衡量标准。次要目标是研究在创造力表达过程中，内视现象是如何出现的。40 名个体在巴西自愿参加安非他命类物质致幻剂仪式，在为期两周的仪式系列结束后的第二天，完成了托兰斯创造性思维测试的视觉部分。21 名没有近期使用迷幻药物的对照受试者也两次间隔两周进行了托兰斯测试。在仪式环境中重复摄入安非他命类物质显著增加了高度原创解决方案和视幻觉反应的数量。然而，在基线时，参加安非他命类物质致幻剂仪式的参与者已经表现出更多的视幻觉解决方案，这可能是因为他们在研究前六个月内经历的迷幻体验比对照受试者多。这项自然主义研究支持了这样一种观点，即在急性精神活性作用消退后，仪式使用安非他命类物质可能会增加某些视觉创造力的衡量标准。它还表明，在重复摄入安非他命类物质后，内视活动增加。
