Subjects made mirror-normal discriminations on alphanumeric characters shown in different orientations in the picture plane. Either the characters or the background rotated during stimulus presentation in Experiments 1-3. Character rotation in the direction of mental rotation facilitated mental rotation, whereas rotation in the opposite direction inhibited it. In Experiment 4, characters were presented in different surface media so as to stimulate only one representation at a time. Mental rotation performance was similar whether the stimuli were defined by luminance, color, texture, relative motion, or binocular disparity, suggesting that mental rotation occurs at a level beyond that of the independent analyses of these different media. These results support those of Experiments 1-3 in excluding the participation of low-level motion analysis centers in the mental rotation processes.
实验对象能够对图片平面中以不同方向呈现的字母数字字符进行镜像-正常辨别。在实验1-3中，刺激呈现期间字符或背景会发生旋转。字符沿心理旋转方向旋转促进了心理旋转，而沿相反方向旋转则抑制了心理旋转。在实验4中，字符以不同的表面媒介呈现，以便每次仅刺激一种表征。无论刺激是由亮度、颜色、纹理、相对运动还是双眼视差定义的，心理旋转表现都相似，这表明心理旋转发生在超出对这些不同媒介进行独立分析的水平上。这些结果支持了实验1-3的结果，即排除了低水平运动分析中心参与心理旋转过程。
