对人类物体识别能力的分析导致了人类视觉中使用两种空间关系表征的假设。在4个实验中提供了区分抽象类别空间关系表征和具体坐标空间关系表征的证据。这些结果表明，Ss作出分类判断开/关，左/右，上/下，更快的刺激时，最初提交给左大脑半球，而他们作出的距离评价，在2毫米，3毫米，或1英寸。(2.54 cm）-当刺激最初呈现给右大脑半球时更快。此外，有证据表明，分类表征是随着实践而发展的。
Analyses of human object recognition abilities led to the hypothesis that 2 kinds of spatial relation representations are used in human vision. Evidence for the distinction between abstract categorical spatial relation representations and specific coordinate spatial relation representations was provided in 4 experiments. These results indicate that Ss make categorical judgments—on/off, left/right, and above/below—faster when stimuli are initially presented to the left cerebral hemisphere, whereas they make evaluations of distance—in relation to 2 mm, 3 mm, or 1 in.(2.54 cm)—faster when stimuli are initially presented to the right cerebral hemisphere. In addition, there was evidence that categorical representations developed with practice.
