The effects of bilateral display symmetry on simultaneous comparison were examined. Experiment 1 demonstrated that symmetric letter pairs are classified as same more rapidly and accurately than asymmetric letter pairs. Experiments 2 and 3 disentangled the contributions of single-letter and whole-display symmetries (these being confounded in normal letter pairs) and showed that the primary determinant of response facilitation is the presence and registration of interitem relational structure. The last three experiments suggested that this facilitation does not arise from the detection and diagnostic utilization of symmetry. It is concluded that bilateral display symmetry facilitates the normal operations of form comparison. The early operations of field segmentation are discussed as the probable locus for this facilitation effect.
研究了双边显示对称性对同时比较的影响。实验1表明，对称字母对比不对称字母对被归类为相同的速度更快且更准确。实验2和实验3区分了单个字母对称性和整个显示对称性的作用（在正常字母对中这两者相互混淆），并表明反应促进的主要决定因素是项目间关系结构的存在和记录。最后三个实验表明，这种促进作用并非源于对称性的检测和诊断性利用。得出的结论是，双边显示对称性促进了形式比较的正常操作。文中讨论了早期的视野分割操作可能是这种促进作用的发生位点。
