The correspondence problem is a classic issue in vision and cognition. Frequent perceptual disruptions, such as saccades and brief occlusion, create gaps in perceptual input. How does the visual system establish correspondence between objects visible before and after the disruption? Current theories hold that object correspondence is established solely on the basis of an object's spatiotemporal properties and that an object's surface feature properties (such as color or shape) are not consulted in correspondence operations. In five experiments, we tested the relative contributions of spatiotemporal and surface feature properties to establishing object correspondence across brief occlusion. Correspondence operations were strongly influenced both by the consistency of an object's spatiotemporal properties across occlusion and by the consistency of an object's surface feature properties across occlusion. These data argue against the claim that spatiotemporal cues dominate the computation of object correspondence. Instead, the visual system consults multiple sources of relevant information to establish continuity across perceptual disruption.
对应问题是视觉和认知领域的一个经典问题。频繁的感知干扰,如扫视和短暂遮挡,会在感知输入中造成缺口。视觉系统如何在干扰前后可见的物体之间建立对应关系?当前理论认为,物体对应关系完全基于物体的时空属性来建立,并且在对应操作中不考虑物体的表面特征属性(如颜色或形状)。在五个实验中,我们测试了时空属性和表面特征属性对跨越短暂遮挡建立物体对应关系的相对贡献。对应操作受到物体在遮挡前后时空属性的一致性以及物体在遮挡前后表面特征属性的一致性的强烈影响。这些数据反驳了时空线索主导物体对应关系计算的说法。相反,视觉系统会参考多个相关信息源来建立跨越感知干扰的连续性。
