研究人员比较了人类和猴子对复杂形状的感知。这两个物种的成员参与了一个相同-不同的范式，在这个范式中，他们判断形状对的相似性，这些形状对可能是同一潜在原型的变体。这两个物种的相似性梯度从心理空间的转换中心向外陡峭。相反，从心理空间的边缘到中心，相似性梯度是平坦的。这些结果表明，在人类和猴子的形状感知和形状比较过程中，存在着重要的共同原则。得到了相同的心理空间的一般组织形式。心理距离也采用了同样的可量化衡量标准。已建立的创造受控形状变异的方法对两个物种的相似性判断具有相同的效果。在心理空间中处于外围的待判断形状对的成员控制感知到的该对的相似性的强度。研究结果对知觉和范畴化的比较研究具有更广泛的意义。
The authors compared the complex shape perception of humans and monkeys. Members of both species participated in a Same–Different paradigm in which they judged the similarity of shape pairs that could be variations of the same underlying prototype. For both species, similarity gradients were found to be steep going out from the transformational center of psychological space. In contrast, similarity gradients were found to be flat going from the periphery in toward the center of psychological space. These results show that there are important common principles in the shape-perception and shape-comparison processes of humans and monkeys. The same general organization of psychological space is obtained. The same quantifiable metric of psychological distance is applied. Established methods for creating controlled shape variation have the same effect on both species’ similarity judgments. The member of the to-be-judged pair of shapes that is peripheral in psychological space controls the strength of the perceived similarity of the pair. The results have broader implications for the comparative study of perception and categorization.
