In summary, in addition to the cultural, parental, developmental, and dynamic factors which support mutual identification and/or failure of separation between twins, it is my thesis that the basic early identifications between twins rely heavily on relatively conflict-free perceptual modes (visual, auditory, kinesthetic, etc.) quite different from the conflict-laden drive modes we usually think of when considering identification. Furthermore, identification based on perceptual modes, which are relatively free of conflict in early development, become extremely difficult to analyze, as analytic progress depends on conflict.
总之，除了那些支持双胞胎之间相互认同和/或分离失败的文化、父母、发展和动态因素外，我的论点是，双胞胎之间早期的基本认同很大程度上依赖于相对无冲突的感知模式（视觉、听觉、动觉等），这与我们在考虑认同时通常想到的充满冲突的驱力模式截然不同。此外，基于早期发展中相对无冲突的感知模式的认同变得极难分析，因为分析的进展依赖于冲突。
