最近，M. Boi、H. Ogmen、J. Krummenacher、T. U. Otto 和 M. H. Herzog (2009) 报告了一种令人着迷的视觉效果，其中视运动的方向通过沿着视运动路径（Ternus-Pikler 群运动）的线索消除了歧义，即使在此刺激中没有发生实际运动。他们将他们的研究称为“石蕊测试”，以区分“非视网膜主题”（基于运动）和“视网膜主题”（基于视网膜）图像处理。我们将测试调整为具有简单光栅刺激的测试，该测试可以更容易地建模并通过这种刺激定量地复制其心理物理结果。然后，我们在 3D (x, y, t) 傅里叶空间中对实验进行建模，并证明观察到的感知效果很容易通过在面向空间和时间的探测器内集成信息来解释，这与之前对其他运动错觉的解释类似。这个演示带来了 Boi 等人的研究。进入对移动物体的感知的更一般的背景。
Recently, M. Boi, H. Ogmen, J. Krummenacher, T. U. Otto, & M. H. Herzog (2009) reported a fascinating visual effect, where the direction of apparent motion was disambiguated by cues along the path of apparent motion, the Ternus-Pikler group motion, even though no actual movement occurs in this stimulus. They referred to their study as a "litmus test" to distinguish "non-retinotopic" (motion-based) from "retinotopic" (retina-based) image processing. We adapted the test to one with simple grating stimuli that could be more readily modeled and replicated their psychophysical results quantitatively with this stimulus. We then modeled our experiments in 3D (x, y, t) Fourier space and demonstrated that the observed perceptual effects are readily accounted for by integration of information within a detector that is oriented in space and time, in a similar way to previous explanations of other motion illusions. This demonstration brings the study of Boi et al. into the more general context of perception of moving objects.
