心理旋转的原始研究估计，当比较两个同时描绘的三维形状（R. Shepard 和 J. Metzler）时，想象旋转的速度比将一个二维形状与先前学习的二维形状（Cooper 和她的同事）进行比较时要慢得多。在 2×2 设计中，我们正交改变对象的维度和任务类型。这两个因素都会影响反应时间。任务类型是估计心理旋转速率的主要决定因素，单刺激任务的估计速率大约是单刺激任务的三倍。维度主要影响所有反应时间的附加分量，这表明三维形状需要更多的初始编码。在缺乏令人满意的控制刺激复杂性的方法的情况下，结果至少与以下提议一致：一旦三维物体被编码，它们的旋转可以像二维形状的旋转一样快速地想象。（PsycINFO数据库记录（c）2016 APA，保留所有权利）
The original studies of mental rotation estimated rates of imagining rotations that were much slower when two simultaneously portrayed three-dimensional shapes were to be compared (R. Shepard & J. Metzler) than when one two-dimensional shape was to be compared with a previously learned two-dimensional shape (Cooper and her associates). In a 2× 2 design, we orthogonally varied dimensionality of objects and type of task. Both factors affected reaction times. Type of task was the primary determiner of estimated rate of mental rotation, which was about three times higher for the single-stimulus task. Dimensionality primarily affected an additive component of all reaction times, suggesting that more initial encoding is required for three-dimensional shapes. In the absence of a satisfactory way of controlling stimulus complexity, the results are at least consistent with the proposal that once three-dimensional objects have been encoded, their rotation can be imagined as rapidly as the rotation of two-dimensional shapes.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
