A 1983-1985 theory by Mitchell and Power predicts that, when rotating rectangles undergo certain kinds of speed fluctuation, they should appear to reverse just as trapezia do. The prediction is partially confirmed. One of two 'mimic' rectangles underwent apparent reversals more often than a control rectangle undergoing even rotation and in the same places as rotating trapezia. However, its reversal frequency was less than those of the trapezia, and a second 'mimic' slowed an inappropriate distribution of reversals round the cycle. These anomalies call for some modification to Mitchell and Power's theory, but minor qualifications may be sufficient.
米切尔和鲍尔于1983年至1985年提出的理论预测，当旋转的矩形经历某些类型的速度波动时，它们应该会像梯形一样出现反转现象。这一预测得到了部分证实。两个“模拟”矩形中的一个比进行匀速旋转的对照矩形更频繁地出现明显反转，且反转位置与旋转梯形相同。然而，其反转频率低于梯形，并且第二个“模拟”矩形减缓了反转在周期内的不当分布。这些异常情况需要对米切尔和鲍尔的理论进行一些修正，但小的调整可能就足够了。
