This paper examines Nakamura Kokyō's study of a woman with a split personality who lived in his home as a maid from 1917 until her death in 1940. She was his indispensable muse and assistant in his efforts to promote abnormal psychology and psychotherapy. This paper first explores the central position of multiple personality in Nakamura's theory of the subconscious, which was largely based on the model of dissociation. It then examines how it became a central issue in Nakamura's disputes with religions including the element of spirit possession, which invoked Western psychical research to modernize their doctrines. While both were concerned with the subconscious and alterations in personality, Nakamura's psychological view was distinguished from those spiritual understandings by his emphasis on individual memories, particularly those that were traumatic, and hysteria. The remaining sections of the paper will examine Nakamura's views on memory and hysteria, which conflicted with both the academic mainstream and the established cultural beliefs. This conflict may partly explain the limited success of Nakamura's academic and social campaigns.

寻求双重人格：20 世纪早期日本的中村光京在变态心理学方面的工作。

这篇论文考察了中村幸景对一位人格分裂的女性的研究，她从 1917 年到 1940 年去世，一直作为女仆住在他家中。她是他推动反常心理学和心理治疗的不可或缺的缪斯和助手。本文首先探讨了多重人格在中村潜意识理论中的核心地位，该理论主要基于分离模型。然后，它研究了它如何成为 Nakamura 与宗教争论的核心问题，包括精神占有的因素，这引用了西方的心理学研究来使他们的教义现代化。虽然两者都关注潜意识和人格的改变，但中村的心理学观点与那些精神理解不同，因为他强调个人记忆，尤其是那些受到创伤和歇斯底里的人。论文的其余部分将考察中村对记忆和歇斯底里的看法，这与学术主流和既定的文化信仰相冲突。这种冲突可能部分解释了中村的学术和社会运动取得的有限成功。
