This study examined two related phenomena: (a) the judgment of whether a human body part belongs to the left or right half of the body and (b) the imagined spatial transformation of one's body. In three experiments, observers made left-right judgments of a part of a body whose orientation differed from their own by a rotation about one of 13 axes. To do so, they imagined themselves passing to the orientation of the stimulus. Time for (a) left-right judgments and (b) accompanying imagined spatial transformations depended on the extent of the orientation difference (OD) between the observer and stimulus. More important, time for phenomena (a) and (b) depended strongly, and in the same way, on the direction of OD. Further results showed that the rate of imagined spatial transformations can vary strongly for different axes and directions of rotation about an axis. These and other results (e.g., Parsons, 1987a) suggest that temporal and kinematic properties of imagined spatial transformations are more object-specific than could be previously assumed.
（a）对人体某一部位属于身体左半部分还是右半部分的判断，以及（b）对自身身体的想象空间转换。在三个实验中，观察者对一个身体部位进行左右判断，该部位的朝向通过绕13个轴之一的旋转与他们自己的朝向不同。为此，他们想象自己转到刺激物的朝向。（a）左右判断和（b）伴随的想象空间转换的时间取决于观察者与刺激物之间的朝向差异（OD）程度。更重要的是，现象（a）和（b）的时间强烈且以相同方式取决于OD的方向。进一步的结果表明，想象空间转换的速率对于不同的轴以及绕轴旋转的方向可能有很大差异。这些以及其他结果（例如，帕森斯，1987a）表明，想象空间转换的时间和运动学特性比之前所认为的更具对象特异性。
