When a bilaterally asymmetrical figure is drawn on the skin at various bodily positions, the observer often reports that the figure he "sees" is reversed. On the head and neck, for example, figures drawn to the front of an imaginary line through the centre of the head, approximately in line with the ear canal are seen as reversed, and those to the rear of this line as correctly orientated. Different bodily locations such as the palm were tried and the orientation was found to depend in most instances upon the direction in which the surface faced. Several possible theories were tested against the data.
当在身体的不同部位的皮肤上绘制一个双侧不对称的图形时，观察者常常报告说，他“看到”的图形是颠倒的。例如，在头部和颈部，绘制在通过头部中心的假想线前方、大致与耳道对齐的图形被视为颠倒的，而在这条线后方的图形则被视为方向正确。人们尝试了不同的身体部位，如手掌，发现其方向在大多数情况下取决于表面所面对的方向。针对这些数据对几种可能的理论进行了检验。
