The influence of temporal association on the representation and recognition of objects was investigated. Observers were shown sequences of novel faces in which the identity of the face changed as the head rotated. As a result, observers showed a tendency to treat the views as if they were of the same person. Additional experiments revealed that this was only true if the training sequences depicted head rotations rather than jumbled views; in other words, the sequence had to be spatially as well as temporally smooth. Results suggest that we are continuously associating views of objects to support later recognition, and that we do so not only on the basis of the physical similarity, but also the correlated appearance in time of the objects.
研究了时间关联对物体表征和识别的影响。向观察者展示了新面孔序列,其中面孔的身份随着头部旋转而变化。结果,观察者表现出一种倾向,即把这些视图当作是同一个人的视图来对待。额外的实验表明,只有当训练序列描绘的是头部旋转而不是杂乱的视图时,情况才是如此;换句话说,序列在空间和时间上都必须是平滑的。结果表明,我们不断地将物体的视图联系起来以支持后续识别,而且我们这样做不仅基于物理相似性,还基于物体在时间上的相关外观。
