参与者完成了两个对象匹配任务，这些对象是由鸽子组成的新奇的、不可命名的对象。对于每个原始刺激，应用两次转换来创建比较刺激。在分类变换中，连接到geon a的geon被移动到geon b。在坐标变换中，连接到geon a的geon被移动到geon a上的不同位置。坐标任务由原始对象和坐标变换后的对象组成。将原始物体呈现在中央视野，然后将比较物体呈现在左、右半视野（RVF和LVF）。结果显示，在分类任务中RVF有优势，在坐标任务中LVF有优势。讨论了范畴和坐标空间处理子系统作为范畴间和范畴内目标识别基本计算要素的可能性。(C) 2009爱思唯尔公司版权所有
Participants performed two object-matching tasks for novel, non-nameable objects consisting of geons. For each original stimulus, two transformations were applied to create comparison stimuli. In the categorical transformation, a geon connected to geon A was moved to geon B. In the coordinate transformation, a geon connected to geon A was moved to a different position on geon A. The Categorical task consisted of the original and the categorically transformed objects. The Coordinate task consisted of the original and the coordinately transformed objects. The original object was presented to the central visual field, followed by a comparison object presented to the right or left visual half-fields (RVF and LVF). The results showed an RVF advantage for the Categorical task and an LVF advantage for the Coordinate task. The possibility that categorical and coordinate spatial processing subsystems would be basic computational elements for between- and within-category object recognition was discussed.
