先前的研究表明，由于姿势和表情的变化，对陌生面孔的识别容易受到图像变化的影响。然而，关于新面孔上的这些变化是如何学习和处理的，我们知之甚少。我们的目的是调查暴露在一种类型的变异中是否有助于在未经训练的变异中识别。在实验1中，面孔被训练成多个或单一的姿势，但用一个新的表情进行测试。在实验2中，面孔被训练成多个或单一的表情，但被测试了一个新的姿势。我们发现，较高水平的姿势信息暴露有助于以新表情识别训练过的面孔。然而，多重表情训练未能转移到一个新的姿势。研究结果表明，姿势训练的泛化可以扩展到不同类型的变异，而表情训练的泛化在很大程度上局限于已训练的变异类型。(C)2008爱思唯尔有限公司。保留所有权利。
Prior research has shown that recognition of unfamiliar faces is susceptible to image variations due to pose and expression changes. However, little is known about how these variations on a new face are learnt and handled. We aimed to investigate whether exposures to one type of variation facilitate recognition in the untrained variation. In Experiment 1, faces were trained in multiple or single pose but were tested with a new expression. In Experiment 2, faces were trained in multiple or single expression but were tested in a new pose. We found that higher level of exposure to pose information facilitated recognition of the trained face in a new expression. However, multiple-expression training failed to transfer to a new pose. The findings suggest that generalisation of pose training may be extended to different types of variation whereas generalisation of expression training is largely confined within the trained type of variation.
