Mental rotation of a visual image may or may not accompany judgment as to whether two figures shown in different orientations are identical to each other or not. Takano (1989) developed the information type theory, which claims that mental rotation or some alternative strategies to cope with orientation difference are needed when the two figures are mirror images of each other. Later, Cohen & Kubovy (1993) reported that mental rotation did not occur when mirror image discrimination was required together with pressure to curtail reaction time. In the present study, their procedures were followed to see if their results are replicable. Mental rotation did not occur regardless of the presence or absence of RT pressure. Thus, their results were not replicated. Analyses of the participants' reports suggested that some of them employed alternative strategies (see Takano, 1987) instead of mental rotation and that some of them formed mental representation in different orientations other than the one in which the figure was originally presented.

视觉图像的心理旋转可能会也可能不会伴随着判断两个以不同方向显示的图形是否彼此相同。Takano（1989）发展了信息类型理论，认为当两个图形互为镜像时，需要心理旋转或其他策略来科普取向差异。后来，Cohen & Kubovy（1993）报告说，当镜像辨别需要与压力一起减少反应时间时，心理旋转不会发生。在本研究中，他们的程序被遵循，看看他们的结果是否可复制。无论RT压力的存在与否，心理旋转都不会发生。因此，他们的结果没有被复制。对参与者报告的分析表明，他们中的一些人采用了替代策略（见Takano，1987）而不是心理旋转，他们中的一些人形成了不同方向的心理表征，而不是最初呈现图形的方向。
