In three experiments, we examined the role of structural similarity and different types of motion on the efficiency of performing same--different shape judgments across changes in viewpoints. In all experiments, participants judged whether two novel, multi-part objects were structurally identical, and they were to ignore any viewpoint or motion differences between the objects. In experiment 1, participants were affected by viewpoint differences more for structurally similar than structurally distinct objects, but this interaction was mitigated by rigid motion. In experiments 2 and 3, we used only structurally similar objects that moved only some of their parts, either in a similar way between objects within a pair or in distinctive ways. Participants' recognition performance was facilitated by this articulated motion relative to both static and scrambled controls. We conclude that coherent motion facilitates generalisation across different views of dynamic objects under some conditions.
在三项实验中，我们研究了结构相似性和不同类型的运动对跨视角变化进行相同-不同形状判断的效率的影响。在所有实验中，参与者判断两个新颖的、多部分的物体在结构上是否相同，并且要忽略物体之间的任何视角或运动差异。在实验1中，对于结构相似的物体，参与者受视角差异的影响比结构不同的物体更大，但这种相互作用因刚体运动而减弱。在实验2和实验3中，我们只使用了结构相似的物体，这些物体只有部分部件发生运动，要么在一对物体中的物体之间以相似的方式运动，要么以独特的方式运动。相对于静态和打乱的控制条件，这种关节运动促进了参与者的识别表现。我们得出结论，在某些条件下，连贯运动有助于对动态物体的不同视图进行泛化。
