与其他物体相比，人脸在直立时比倒立时更能被准确识别。这种倒置效应可能与专业知识的差异有关。在这里，我们探讨刺激的特点和专业知识如何相互作用，以确定反转效应的大小。观察员接受了识别房屋或纹理的培训。在训练前，两种刺激都没有发现倒置效应，但在5天的练习后发现了倒置效应。此外，学习诱发的反转效应表现出部分转移到新的样例。虽然类似的学习量观察到这两种类型的刺激，反转效果显着较大的纹理。我们的研究结果表明，反转效应的大小是不是一个可靠的指标，面对特定的处理。(C)2007爱思唯尔有限公司保留所有权利。
Faces, more than other objects, are identified more accurately when upright than inverted. This inversion effect may be linked to differences in expertise. Here, we explore how stimulus characteristics and expertise interact to determine the magnitude of inversion effects. Observers were trained to identify houses or textures. inversion effects were not found with either stimulus before training, but were found following 5 days of practice. Additionally, the learning-induced inversion effects showed partial transfer to novel exemplars. Although similar amounts of learning were observed with both types of stimuli, inversion effects were significantly larger for textures. Our results suggest that the size of the inversion effect is not a reliable index of face-specific processing. (C) 2007 Elsevier Ltd. All rights reserved.
