用14个SS进行了3个实验，以测量在正方形视场图案中检测对称性的时间。在训练有素和幼稚的SS中，不同对称性的平均检测时间(DT)之间的关系是相同的。当任务是检测任何对称性时，多个对称模式的DT比单一对称模式的DT更快。水平-垂直对称快于对角线，对角线快于中心线。当任务是检测特定的对称性时--即只检测垂直、水平、对角或中心的对称性--对于多个对称模式，DT再次变得更快，这表明“无关”的对称性有助于提高性能。误差和响应时间表明，某些对称性比其他对称性更难拒绝，这取决于对称性的类型。结果表明，干扰效应是由某些对称性引起的，最好的解释是一个对称性被整体编码的模型。因此，当任务需要解码时，如在检测任务中，S执行代码的连续、分层分解。(参考文献35)(心理信息数据库记录(C)2016年APA，版权所有)
Conducted 3 experiments with 14 Ss to measure the time to detect symmetries in square field patterns. The same relationships among mean detection times (DTs) for different symmetries were found in both well-practiced and naive Ss. When the task was to detect any symmetry, DTs were faster for multiple symmetric patterns than for singly symmetric ones. Horizontal–vertical symmetry was faster than diagonal, which was faster than centric. When the task was to detect specific symmetry—that is, vertical, horizontal, diagonal, or centric only—DTs were faster again for multiple symmetric patterns, suggesting that" irrelevant" symmetry facilitated performance. Errors and response times indicate that certain symmetries were more difficult to reject than others, depending on the type of symmetry. Results suggest interference effects arising from certain symmetries and are best accounted for by a model in which symmetry is encoded integrally. Thus, when decoding is required by the task, as in detection tasks, S performs a serial, hierarchical decomposition of the code.(35 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
