Two experiments are reported in which the effect of combining stimuli of changing size and changing vergence on the perception of motion in depth was examined. Changing size and changing vergence corresponded to in-phase or anti-phase sinusoidal motions of an outline circle, with different amplitudes. In-phase stimuli had approximately additive effects on the estimated peak-to-peak amplitude of apparent motion in depth. Anti-phase stimuli did not cancel each other; apparent motion was in-phase with one or the other stimulus. When apparent motion was in-phase with one stimulus, there was only a limited influence of the other stimulus. The results are discussed with regard to a model proposed by Regan and Beverley for the combination of changing size and changing disparity.
本文报告了两项实验，研究了大小变化和聚散变化的刺激相结合对深度运动感知的影响。大小变化和聚散变化对应于轮廓圆的同相或反相正弦运动，幅度不同。同相刺激对深度上明显运动的估计峰峰值幅度具有近似相加的效应。反相刺激不会相互抵消；明显运动与其中一个刺激同相。当明显运动与一个刺激同相时，另一个刺激的影响有限。根据Regan和Beverley提出的关于大小变化和视差变化相结合的模型对结果进行了讨论。
