We compared the effect of motion cues on people's ability to: (1) recognize dynamic objects by combining information from more than one view and (2) perform more efficiently on views that followed the global direction of the trained views. Participants learned to discriminate two objects that were either structurally similar or distinct and that were rotating in depth in either a coherent or scrambled motion sequence. The Training views revealed 60 degrees of the object, with a center 30 degrees segment missing. For similar stimuli only, there was a facilitative effect of motion: Performance in the coherent condition was better on views following the training views than on equidistant preceding views. Importantly, the viewpoint between the two training viewpoints was responded to more efficiently than either the Pre- or Post-Training viewpoints for both the coherent and scrambled condition. The results indicate that view combination and processing coherent motion cues may occur through different processes.
（1）通过整合来自多个视角的信息来识别动态物体，以及（2）在遵循训练视角全局方向的后续视角上更高效地执行任务。参与者学习区分两个在结构上相似或不同的物体，这些物体在深度上以连贯或混乱的运动序列旋转。训练视角展示了物体的60度，中间有一个30度的中心部分缺失。仅对于相似刺激，运动具有促进作用：在连贯条件下，遵循训练视角的后续视角上的表现优于同等距离的先前视角。重要的是，对于连贯和混乱条件，两个训练视角之间的视角比训练前或训练后的视角得到了更高效的响应。结果表明，视角组合和处理连贯运动线索可能通过不同的过程发生。
