许多理论家认为，伸长轴和/或对称轴在物体识别中起着重要作用。在本文中，证据被提出，减轻了这一主张，从独立评估的影响的延伸轴或对称的时间命名旋转线条图的普通对象。这一结论在一个更强的测试中得到了进一步的支持，在这个测试中，这两个变量都是正交控制的，伸长的纵横比被操纵，只有完全几何对称或不对称的物体才被使用。在所有的实验中，物体被命名为几个块，以确定这些变量对定向效果的影响与实践。在练习命名对象集之后，对称性被发现会减少方向的影响，当两个轴定义相同的方向时，相对于定义不同的方向，最极端的方向（垂直120度）测试的效果会减弱。与许多理论相反，这些发现将对称轴和延伸轴在物体识别过程中相对次要的作用降级。
Many theorists have postulated that axes of elongation and/or symmetry play an important role in the recognition of objects. In this paper, evidence is presented that mitigates this claim from independent assessments of the effects of axes of elongation or symmetry on the time to name rotated line drawings of common objects. This conclusion was further supported in a stronger test in which both of these variables were orthogonally controlled, the aspect ratio of elongation was manipulated, and only objects that were completely geometrically symmetrical or asymmetrical were used. In all the experiments, objects were named for several blocks to determine the influence of these variables on effects of orientation with practice. Symmetry was found to diminish the effects of orientation after practice in naming the object set, and the effects of the most extreme orientation tested (120degrees from upright) were diminished when both axes defined the same orientation, relative to when they defined different orientations. Contrary to many theories, these findings relegate the axes of symmetry and elongation to relatively minor roles during object identification.
