诱导运动不限于锋平行平面上的连续运动。实验进行了调查的诱导运动的理论必须适用的几种品种。观察者指示垂直移动测试点的感知运动路径，其中通过两个诱导点的运动将与物理运动成直角的诱导运动添加到该垂直移动测试点。在实验1中，所有的运动（无论是表面上的还是物理上的）都在一个锋平行平面上。结果发现，离散位移以及连续运动的测试和诱导点产生大量的诱导。在实验2中，诱导点在立体距离上连续移动，而不是保持在一个明显的前平行平面上。在垂直移动的测试点中发现了大量的深度上的视运动，并将其解释为深度上的诱导运动。在实验3中，对实验2的现象的另一种解释进行了研究，发现不太可能。在实验4中，所有的点在一个frontoparallel平面上连续移动，眼运动以及诱导运动进行了测量，观察者固定测试点或诱导点。在两种固定条件下均获得了大量的诱导。这些研究结果的理论引起的运动的后果进行了讨论。
Induced motion is not limited to continuous motions presented on a frontoparallel plane. Experiments were conducted to investigate several varieties of induced motion to which theories of induced motion must apply. The observer indicated the perceived path of motion of a vertically moving test point to which induced motion at right angles to the physical motion was added by the motion of two inducing points. In experiment 1 all motions (both apparently and physically) were in a frontoparallel plane. It was found that discrete displacement as well as continuous motion of the test and inducing points produced substantial amounts of induction. In experiment 2 the inducing points were continuously moved in stereoscopic distance rather than remaining in an apparent frontoparallel plane. A large amount of apparent motion in depth was found in the vertically moving test point and was interpreted as an induced motion in depth. In experiment 3 an alternative interpretation of the phenomenon of experiment 2, in terms of an apparent vergence for the two images of the test point, was investigated and found to be unlikely. In experiment 4, with all the points moving continuously in a frontoparallel plane, eye motions as well as induced motions were measured, with the observer fixating either the test point or an inducing point. Substantial amounts of induction were obtained under both conditions of fixation. The consequences of these findings for theories of induced motion are discussed.
