据报道，有四个实验研究了图像或参照框在心理旋转任务中是否会发生变化。在所有实验中，四个相同的字母(P1)以与直立成+90度或-90度的角度显示，受试者必须判断这些字母是正常反射还是镜像反射。100毫秒后，一个字母(P2)以不同的方向呈现，任务指令相同。评估对P2的反应时间，以确定P2的图像是否旋转到直立，或者内部参照系是否从P1的方向旋转到与P2一致。结果表明，P2的转换既可以相对于垂直方向启动，也可以相对于P1方向启动。它们进一步表明，使用每个参考方向的概率可以通过程序变化来改变。这些发现被最简明地解释为心理旋转涉及参照系的转换，而不是模板式表征的转换。
Four experiments are reported that investigate whether images or reference frames are transformed during a mental rotation task. In all experiments a display of four identical letters (P1) was presented at either +90 degrees or -90 degrees from upright, and subjects had to decide whether the letters were normal or mirror-image reflections. A single letter (P2) was then presented 100 ms later in a variable orientation with the same task instructions. Reaction times to P2 were assessed to determine whether an image of P2 was rotated to upright or whether an internal reference frame was rotated into congruence with P2 from the orientation of P1. The results as a whole suggest that transformations of P2 can be initiated either relative to upright or relative to the orientation of P1. They further indicate that the probability of using each reference orientation can be changed by procedural variations. The findings are most parsimoniously interpreted as suggesting that mental rotation involves the transformation of reference frames rather than the transformation of template-like representations.
