Koro, a state where the perception of penis length decreases due to shrinkage from intra-abdominal traction, constitutes the central pathology. The present study was an attempt to explore the penis perception of the Koro patients by devising a graphomotor projective test, the Draw-a-penis Test (DAPT). DAPT elicited the penis image of the drawer, both of a normal penis and own penis perception. It also elicited the nature of perceptual process concerning the penile state changes, i.e. from flaccid to extended state. This controlled DAPT investigation showed a perceptual abnormality of penis image of Koro patients. They perceived less penis length, both for the penis of a normal person and their own penis and failed to perceive effectively the morphological change of penile states in terms of length increase. This perceptual abnormality in organ image is discussed in relation to the Koro vulnerability and psychopathology.
缩阳症是一种因腹内牵引导致阴茎收缩，从而使阴茎长度感知下降的状态，它构成了核心病理。本研究试图通过设计一种书写运动投射测试，即画阴茎测试（DAPT），来探究缩阳症患者对阴茎的认知。DAPT引出了绘图者的阴茎图像，包括正常阴茎和自身阴茎认知。它还引出了关于阴茎状态变化（即从疲软状态到勃起状态）的感知过程的性质。这项对照DAPT调查显示，缩阳症患者的阴茎图像存在感知异常。他们对正常人和自己的阴茎长度感知都较低，并且无法有效地感知阴茎状态在长度增加方面的形态变化。本文将结合缩阳症的易感性和精神病理学来讨论这种器官图像的感知异常。
