We conducted a series of psychophysical experiments to investigate the nature and specificity of behavioral interference between mental and manual rotation. Participants were asked to mentally rotate five different types of visual stimuli--hands, faces, tools, cubes, and natural objects--either clockwise or counterclockwise while they simultaneously manually rotated a wheel in the concordant or discordant direction. Our study clearly revealed object-specific interference between manual and mental rotation. In comparison with a neutral baseline condition without any manual rotation, both manual rotation directions generally impaired the mental rotation of cubes. In contrast, the mental rotation of hands was impaired only by discordant manual rotation. This object- and direction-specific interference between manual and mental rotation proved to be independent of task difficulty. We furthermore found an angular distance effect across different stimulus types.
我们进行了一系列心理物理学实验，以研究心理旋转和手动旋转之间行为干扰的性质和特异性。参与者被要求在同时以一致或不一致的方向手动旋转一个轮子时，对五种不同类型的视觉刺激——手、脸、工具、立方体和自然物体——进行顺时针或逆时针的心理旋转。我们的研究清楚地揭示了手动旋转和心理旋转之间特定物体的干扰。与没有任何手动旋转的中性基线条件相比，两个手动旋转方向通常都会损害立方体的心理旋转。相比之下，只有不一致的手动旋转会损害手的心理旋转。手动旋转和心理旋转之间这种特定物体和方向的干扰被证明与任务难度无关。我们还发现了不同刺激类型之间的角距离效应。
