Previous studies found that mirror-gazing at the subject's reflected own face, under a low illumination level, produces acute dissociation. In the present study, a split-mirror was used, which divides the subject's reflected face vertically into two half-faces, and dissociative states were compared to single-mirror gazing. Twelve healthy naïve individuals, who were sampled from students of an Art Academy, volunteered in a within-subject experiment. Dissociative states were measured through a 9-item self-report questionnaire on three scales: illusions of face deformation (derealization); illusions of body detachment (depersonalization); illusions of different self-identity (dissociated identity). Results showed that split-mirror gazing increased dissociation with respect to single-mirror gazing. Illusions of different self-identity, such as double-identity (i.e., left-identity versus right-identity) or double-personality, increased during split-mirror gazing with respect to single-mirror gazing, whereas illusions of face deformation and body detachment were unchanged. Findings support the distinction between detachment and compartmentalization, and may provide a tool for experimental investigation of dissociative identity disorder (DID). Finally, the students' portraits illustrated illusions of self-identity in split-mirror gazing: left-identity (portrayed in the right side of drawings) displayed illusions of more negative personalities and/or emotions, while right-identity (portrayed in the left side) showed more positive features.

分镜凝视会增加分离状态和自我认同的幻觉

以前的研究发现,在低光照水平下,用镜子凝视对象反射的自己的脸会产生严重的分离。在本研究中,使用了分裂镜,将受试者的反射面垂直分成两个半面,并将分离状态与单镜凝视进行比较。从一所艺术学院的学生中抽取的 12 名健康天真个体自愿参加了一项受试者内实验。分离状态是通过 9 项自我报告问卷在三个尺度上测量的:面部变形的错觉(现实感丧失);身体脱离的幻觉(人格解体);不同自我身份(分离身份)的错觉。结果表明,分镜凝视比单镜凝视增加了分离。不同身份的错觉,例如双重身份(即左身份与右身份)或双重人格,在分镜凝视期间相对于单镜凝视增加,而面部变形和身体脱离的错觉没有变化。研究结果支持分离和划分之间的区别,并可能为分离性身份障碍 (DID) 的实验研究提供工具。最后,学生的肖像展示了分镜凝视中的自我认同错觉:左身份(描绘在图纸的右侧)表现出更消极的个性和/或情绪的幻觉,而右身份(描绘在左侧侧)表现出更多的积极特征。相对于单镜凝视,在分镜凝视期间增加,而面部变形和身体脱离的错觉没有变化。研究结果支持分离和划分之间的区别,并可能为分离性身份障碍 (DID) 的实验研究提供工具。最后,学生的肖像展示了分镜凝视中的自我认同错觉:左身份(描绘在图纸的右侧)表现出更消极的个性和/或情绪的幻觉,而右身份(描绘在左侧侧)表现出更多的积极特征。相对于单镜凝视,在分镜凝视期间增加,而面部变形和身体脱离的错觉没有变化。研究结果支持分离和划分之间的区别,并可能为分离性身份障碍 (DID) 的实验研究提供工具。最后,学生的肖像展示了分镜凝视中的自我认同错觉:左身份(描绘在图纸的右侧)表现出更消极的个性和/或情绪的幻觉,而右身份(描绘在左侧侧)表现出更多的积极特征。并可能为分离性身份障碍 (DID) 的实验研究提供工具。最后,学生的肖像展示了分镜凝视中的自我认同错觉:左身份(描绘在图纸的右侧)表现出更消极的个性和/或情绪的幻觉,而右身份(描绘在左侧侧)表现出更多的积极特征。并可能为分离性身份障碍 (DID) 的实验研究提供工具。最后,学生的肖像展示了分镜凝视中的自我认同错觉:左身份(描绘在图纸的右侧)表现出更消极的个性和/或情绪的幻觉,而右身份(描绘在左侧侧)表现出更多的积极特征。
