Evidence indicates that highly hypnotizable subjects may have larger area of the rostrum of the corpus callosum (CC). Mediumship can be defined as the alleged ability to communicate regularly with deceased personalities, and self-hypnosis is postulated as an underlying mechanism for this ability. Therefore, we aimed to investigate the CC area, hypnotic susceptibility, self-reported dissociation, and empathy in alleged mediums in comparison with healthy, non-medium controls.
The study sample consisted of 16 Spiritist mediums (medium group (MG)) and 16 non-medium controls. Magnetic resonance imaging scans were performed to measure the CC areas (total and subdivisions). The Harvard Group Scale of Hypnotic Susceptibility was used to assess hypnotizability, and self-reported measures were used to investigate anomalous experiences, mental health using the Self-Reporting Questionnaire-SRQ, dissociative experiences using the Dissociative Experiences Scale, and empathy using the Interpersonal Reactivity Index.
No between-group differences were found in the total or subdivided CC areas or in hypnotizability, with both groups showing intermediate levels. The rostrum of the CC area and hypnotizability were not correlated. The MG presented with significantly more anomalous experiences, but the two groups had similar scores for dissociation, empathy, and mental health.
The normal CC areas found in the MG are in contrast with the abnormal results typically observed in subjects with psychotic and dissociative disorders. Although hypnotizability was not different between groups, further studies are needed to replicate these findings in other samples.
有证据表明，高度可催眠的受试者胼胝体嘴部（CC）的面积可能更大。灵媒现象可定义为声称能够定期与已故之人交流的能力，自我催眠被假定为这种能力的潜在机制。因此，我们旨在调查所谓的灵媒与健康的非灵媒对照相比，其CC面积、催眠易感性、自我报告的分离体验和共情能力。
研究样本包括16名唯灵论灵媒（灵媒组（MG））和16名非灵媒对照。进行磁共振成像扫描以测量CC面积（总体及各细分部分）。使用哈佛催眠易感性团体量表评估催眠易感性，并使用自我报告测量方法调查异常体验、使用自我报告问卷-SRQ评估心理健康、使用分离体验量表评估分离体验以及使用人际反应指数评估共情能力。
在CC总面积或细分面积以及催眠易感性方面，两组之间未发现差异，两组均呈现中等水平。CC嘴部面积与催眠易感性无相关性。灵媒组出现显著更多的异常体验，但两组在分离体验、共情能力和心理健康方面得分相似。
在灵媒组中发现的正常CC面积与在精神病性和分离性障碍患者中通常观察到的异常结果形成对比。尽管两组之间的催眠易感性没有差异，但需要进一步研究在其他样本中重复这些发现。
