我们描述了一位患有右脑损伤的女性，她否认自己的左手和戴在左手上的体外物体（如戒指）的所有权。当同样的物体戴在右手上或被检查者拿着时，病人正确地认出它们是她自己的。其他与左手无关的个人物品（如别针、耳环、梳子）总是被正确地识别为她自己的。因此，通过推理，一个人身体的心理意象可能包括与身体本身接触或非常接近的无生命物体。这些发现提供了，第一次，实验支持的推测性概念的扩展的身体图式。
WE describe a woman with right brain damage who denied the ownership of her left hand and of extracorporeal objects (e.g. rings) which were worn on the left hand itself. When the same objects were worn on the right hand or were held by the examiner, the patient correctly recognized them as her own. Other personal objects unrelated to the left hand (e.g. pins, earrings, comb) were always correctly recognized as her own. Thus, by inference, the mental image of one's body may include inanimate objects which had been in contact or in close proximity with the body itself. These findings provide, for the first time, experimental support to the speculative notion of an extended body schema.
