There is growing evidence that motion perception is modulated by visual selective attention. In the 'attention-induced motion blindness' paradigm the detection of coherent motion in a random dot kinematogram (RDK) is impaired in a rapid serial presentation task [Sahraie, A., Milders, M., & Niedeggen, M. (2001). Attention induced motion blindness. Vision Research, 41, 1613-1617]. The effect depends on irrelevant motion episodes (distractors) prior to the target. In this study, we show that both the number and timing of distractors affect detection performance, allowing for implications on the build-up and release of inhibition. Furthermore, we rule out the possibility that subjects falsely classify targets as distractors due to uncertainty of temporal order.
越来越多的证据表明，运动知觉受视觉选择性注意的调节。在“注意诱发的运动盲”范式中，随机点运动图（RDK）中连贯运动的检测在快速序列呈现任务中受到损害[Sahraie, A., Milders, M., & Niedeggen, M. (2001). 注意诱发的运动盲。视觉研究，41, 1613 - 1617]。这种效应取决于目标之前的无关运动片段（干扰物）。在本研究中，我们表明干扰物的数量和时间都影响检测性能，这有助于理解抑制的形成和解除。此外，我们排除了由于时间顺序不确定而导致受试者将目标错误分类为干扰物的可能性。
