本研究的目的是确定在人脸识别和基本目标识别中使用的原语之间的关系是否使用坐标关系或分类关系来表示。在两个实验中，作者使用名人的面部照片作为刺激，每张脸都被改变，要么一只眼睛从正常位置向上移动，要么两只眼睛向上移动。参与者在这些刺激下执行面部识别任务或基本水平的物体识别任务。在人脸识别任务中，一眼动的人脸比两眼动的人脸更容易被识别，而在基本水平的物体识别任务中则表现出相反的结果。结果表明，人脸识别涉及一种坐标形状表示，其中指定了视觉原语的精确位置，而基本级别的对象识别使用分类编码关系。
The purpose of this investigation was to determine if the relations among the primitives used in face identification and in basic-level object recognition are represented using coordinate or categorical relations. In 2 experiments the authors used photographs of famous people's faces as stimuli in which each face had been altered to have either 1 of its eyes moved up from its normal position or both of its eyes moved up. Participants performed either a face identification task or a basic-level object recognition task with these stimuli. In the face identification task, I-eye-moved faces were easier to recognize than 2-eyes-moved faces, whereas the basic-level object recognition task showed the opposite pattern of results. Results suggest that face identification involves a coordinate shape representation in which the precise locations of visual primitives are specified, whereas basic-level object recognition uses categorically coded relations.
