表示跨越变化的时间连续对象（例如，在位置上）需要将新采样的视觉信息与现有的对象表示相结合。我们问什么后果表征更新视觉搜索。在这个动态视觉搜索任务中，条围绕其中心轴旋转。观察者搜索单个发作性目标状态（垂直条和水平条中的斜条）。当目标显示器被呈现为孤立的静态显示器时，搜索是有效的。性能下降到近的机会，但是，当同一显示器是一个动态变化的场景（实验1）的单一状态，好像从刺激流的目标显示器的时间选择完全失败（实验3）。赤字是由于既不掩蔽（实验2），也没有时间标记的目标显示（实验4）。通过视觉标记具有独特特征信息的目标显示器（实验5），部分地减少了赤字。我们认为，代表性更新导致损失的瞬时状态信息的访问搜索。类似的空间拥挤的显示器，被认为是纹理，我们提出了一个时间版本的树木（瞬时方向信息）丢失的森林（旋转酒吧）。
Representing temporally continuous objects across change (e.g., in position) requires integration of newly sampled visual information with existing object representations. We asked what consequences representational updating has for visual search. In this dynamic visual search task, bars rotated around their central axis. Observers searched for a single episodic target state (oblique bar among vertical and horizontal bars). Search was efficient when the target display was presented as an isolated static display. Performance declined to near chance, however, when the same display was a single state of a dynamically changing scene (Experiment 1), as though temporal selection of the target display from the stream of stimulation failed entirely (Experiment 3). The deficit is due neither to masking (Experiment 2), nor to a lack of temporal marker for the target display (Experiment 4). The deficit was partially reduced by visually marking the target display with unique feature information (Experiment 5). We suggest that representational updating causes a loss of access to instantaneous state information in search. Similar to spatially crowded displays that are perceived as textures, we propose a temporal version of the trees (instantaneous orientation information) being lost for the forest (rotating bars).
