When objects move in the environment, their retinal images can undergo drastic changes and features of different objects can be inter-mixed in the retinal image. Notwithstanding these changes and ambiguities, the visual system is capable of establishing correctly feature-object relationships as well as maintaining individual identities of objects through space and time. Recently, by using a Ternus-Pikler display, we have shown that perceived motion correspondences serve as the medium for non-retinotopic attribution of features to objects. The purpose of the work reported in this manuscript was to assess whether perceived motion correspondences provide a sufficient condition for feature attribution. Our results show that the introduction of a static "barrier" stimulus can interfere with the feature attribution process. Our results also indicate that the barrier stops feature attribution based on interferences related to the feature attribution process itself rather than on mechanisms related to perceived motion.
当物体在环境中移动时，它们在视网膜上的图像会发生剧烈变化，不同物体的特征可能会在视网膜图像中相互混合。尽管存在这些变化和模糊性，视觉系统仍能够正确地建立特征与物体的关系，并在空间和时间上保持物体的个体身份。最近，通过使用特尔努斯－皮克勒显示器，我们已经表明，感知到的运动对应关系是特征非视网膜定位归因于物体的媒介。本手稿中报告的这项工作的目的是评估感知到的运动对应关系是否为特征归因提供了充分条件。我们的结果表明，引入静态“屏障”刺激会干扰特征归因过程。我们的结果还表明，屏障基于与特征归因过程本身相关的干扰而非与感知运动相关的机制来阻止特征归因。
