Three divided visual field experiments tested current hypotheses about the types of visual shape representation tasks that recruit the cognitive and neural mechanisms underlying face recognition. Experiment 1 found a right hemisphere advantage for subordinate but not basic-level face recognition. Experiment 2 found a right hemisphere advantage for basic but not superordinate-level animal recognition. Experiment 3 found that inverting animals eliminates the right hemisphere advantage for basic-level animal recognition. This pattern of results suggests that the cognitive and neural mechanisms underlying face recognition are recruited when computational demands of a shape representation task are best served through the use of coordinate (rather than categorical) spatial relations.
三项分离视野实验检验了当前关于视觉形状表征任务类型的假设,这些任务会动用面部识别背后的认知和神经机制。实验1发现,在识别从属但非基本水平的面孔时,右半球具有优势。实验2发现,在识别基本但非上级水平的动物时,右半球具有优势。实验3发现,将动物图像倒置会消除右半球在识别基本水平动物时的优势。这种结果模式表明,当形状表征任务的计算需求通过使用坐标(而非分类)空间关系能得到最佳满足时,面部识别背后的认知和神经机制就会被调用。
