场景复杂性如何影响场景中预期的和合适的对象的检测？交通研究表明，易受伤害的道路使用者(VRU：行人、骑自行车的人和骑摩托车的人)有时没有被察觉，尽管是预期的。场景感知模型强调早期感知中对有限神经资源的竞争，预测在快速扫视过程中可能会错过一个对象，因为其他对象赢得了竞争，被个性化和有意识地感知。我们使用交通场景的图片，并通过在被检测的VRU(拥挤)附近插入或移除车辆来操纵复杂性。观察者的唯一任务是在横向展示的图片中检测到VRU。出现了强烈的偏差效应，特别是当VRU被附近的其他车辆拥挤时：观察者未能检测到VRU(高错失率)，同时错误警报错误相对较少。行人的漏检率高达65%。结果表明，当场景复杂度较高时，场景背景会干扰对预期目标的感知。由于城市化大大增加了场景的复杂性，这些结果对公共安全具有重要影响。
How does scene complexity influence the detection of expected and appropriate objects within the scene? Traffic research has indicated that vulnerable road users (VRUs: pedestrians, bicyclists, and motorcyclists) are sometimes not perceived, despite being expected. Models of scene perception emphasize competition for limited neural resources in early perception, predicting that an object can be missed during quick glances because other objects win the competition to be individuated and consciously perceived. We used pictures of traffic scenes and manipulated complexity by inserting or removing vehicles near a to-be-detected VRU (crowding). The observers’ sole task was to detect a VRU in the laterally presented pictures. Strong bias effects occurred, especially when the VRU was crowded by other nearby vehicles: Observers failed to detect the VRU (high miss rates), while making relatively few false alarm errors. Miss rates were as high as 65% for pedestrians. The results indicated that scene context can interfere with the perception of expected objects when scene complexity is high. Because urbanization has greatly increased scene complexity, these results have important implications for public safety.
