The presupposed advantage of symmetrical objects over asymmetrical objects was investigated in an object matching task, using accidental and non-accidental viewpoints. In addition, the accidental views could be symmetric or asymmetric. When two non-accidental views were presented, symmetrical objects were matched faster than asymmetrical objects. When an accidental view was presented first (followed by a non-accidental view), the matching of symmetrical objects was equal to that of asymmetrical objects. When a non-accidental view was presented first (followed by an accidental view), matching was again equal for the symmetrical and asymmetrical objects, although much faster compared with the opposite sequence of presented views. No effects of image symmetry in the accidental viewpoints were found. Apparently, the advantage of symmetrical objects over asymmetrical objects is only present in object matching when 3-D object structures are visible.
在一项物体匹配任务中，利用偶然视角和非偶然视角，研究了对称物体相对于不对称物体的预设优势。此外，偶然视角可以是对称的或不对称的。当呈现两个非偶然视角时，对称物体的匹配速度比不对称物体快。当首先呈现一个偶然视角（随后是一个非偶然视角）时，对称物体的匹配与不对称物体的匹配相当。当首先呈现一个非偶然视角（随后是一个偶然视角）时，对称物体和不对称物体的匹配再次相当，尽管与呈现视角的相反顺序相比要快得多。在偶然视角中未发现图像对称性的影响。显然，对称物体相对于不对称物体的优势仅在三维物体结构可见时的物体匹配中存在。
