In his recent paper "Distorted body representations in anorexia nervosa" Gadsby (2017) discussed empirical evidence regarding anorexic patients' distorted body representations. In particular, he interpreted them using the O'Shaughnessy's long-term body image (LTB) hypothesis (O'Shaughnessy, 1998): individuals with anorexia nervosa (AN) have a distorted LTB that tracks changes in the spatial content of the body and supplies this distorted content to other body representations. Even if we agree on the involvement of body memory in the distorted body representation, an open issue not fully addressed in the paper is: why AN patients do not update their LTBs to reflect their true dimensions? Our correspondence tries to answer to this question using a new neuropsychological and neurobiological theory: the Allocentric Lock Theory - ALT.
在其最近的论文《神经性厌食症中扭曲的身体表征》中，加兹比（2017年）讨论了有关厌食症患者扭曲身体表征的实证证据。特别是，他运用奥肖内西的长期身体意象（LTB）假说（奥肖内西，1998年）对这些证据进行了解读：神经性厌食症（AN）患者具有扭曲的长期身体意象，该意象追踪身体空间内容的变化，并将这种扭曲的内容提供给其他身体表征。即使我们认同身体记忆参与了扭曲的身体表征，但该论文中一个尚未完全解决的开放性问题是：为什么AN患者不更新他们的长期身体意象以反映其真实尺寸？我们的通信试图运用一种新的神经心理学和神经生物学理论——异我中心锁定理论（ALT）来回答这个问题。
