通过特征位置绑定维持情景表征对于视觉认知很重要。有人建议我们可以保存和更新最多四个对象的连贯情景表示。这项研究调查了与多个对象的特征位置绑定的动态维护。在一系列七个实验中，参与者判断了三个或四个颜色圆盘的一系列旋转图案是否包含两个圆盘之间的任何颜色切换。即使成功跟踪物体的运动，颜色切换检测通常也很困难，这表明我们的动态维护能力是有限的。当帧间旋转角度变得足够小时，性能得到改善。此外，时空可预测性对于这种改进是必要的，这表明多种情景表征的维持是我们的预测和感觉机制之间的交互过程。
Maintenance of episodic representations by feature-location binding is important for visual cognition. It has been proposed that we can hold and update coherent episodic representations of up to four objects. This study investigated the dynamic maintenance of feature-location bindings with multiple objects. In a series of seven experiments, participants judged whether a sequence of rotating patterns of three or four colored disks contains any color switch between two disks. Color-switch detection is in general difficult, even when tracking of objects' motions is successful, suggesting that our ability for dynamic maintenance is limited. The performance improved when the interframe rotation angle became sufficiently small. Moreover, spatiotemporal predictability was necessary for this improvement, suggesting that the maintenance of multiple episodic representations is an interactive process between our prediction and sensory mechanisms.
