本文报道了两个关于头部倾斜对心理旋转影响的实验。在实验一中，[人类]受试者决定是否在一条线上重复点图案。他们的反应时间（RT）与他们的解释一致，即他们在做决定之前，在心理上旋转了图案，这样主观上线是垂直的。当受试者倾斜头部时，RT函数改变了倾斜的方向，这表明主观垂直比重力垂直更接近视网膜。在实验二中，被试决定在不同方向上单个呈现的字母数字字符是标准的还是反向的（镜像反转）。再一次，他们的RT分析表明心理旋转到标准直立，但功能不受头部倾斜的影响；在这种情况下，受试者在主观重力而不是视网膜坐标下操作。视网膜坐标或重力坐标的选择可能取决于刺激是被解释为以自我为中心还是作为外部世界的一部分。
Two experiments on the influence of head tilt on mental rotation are reported. In Experiment I, [human] subjects decided whether dot patterns were or were not repeated about a line. Their reaction times (RT) were consistent with the interpretation that they mentally rotated the patterns so that the line was subjectively vertical before making their decisions. When the subjects tilted their heads, the RT functions shifted the direction of the tilt, indicating that the subjective vertical lay closer to the retinal than to the gravitational vertical. In Experiment II, subjects decided whether singly presented alphanumeric characters in various orientations were standard or backward (mirror-reversed). Again, analysis of their RT suggested mental rotation to the standard upright, but the function was unaffected by head tilt; in this case, the subjects operated in subjective gravitational rather than retinal coordinates. The choice of retinal or gravitational coordinates may depend on whether the stimuli are interpreted egocentrically or as part of the external world.
