There are several models of the use of geometric and feature cues in reorientation (Cheng, Huttenlocher, & Newcombe, ). The adaptive combination approach posits that people integrate cues with weights that depend on cue salience and learning, or, when discrepancies are large, they choose between cues based on these variables (Cheng, Shettleworth, Huttenlocher, & Rieser, ; Newcombe & Huttenlocher, ). In a new paradigm designed to evaluate integration and choice, disoriented participants attempted to return to a heading direction, in a trapezoidal enclosure in which feature and geometric cues both unambiguously specified a heading, but later the feature was moved. With discrepancies greater than 90 degrees, participants choose geometry. With smaller discrepancies, integration appeared in three of five situations; otherwise, participants used geometry alone. Variation depended on direction of feature movement and whether the nearest corner was acute or obtuse. The results have implications for contrasting adaptive combination and modularity theory, and for future research, offering a new paradigm for reorientation research, and for testing cue integration more broadly.
在重新定向过程中，存在几种关于几何和特征线索使用的模型（Cheng、Huttenlocher和Newcombe， ）。适应性组合方法假定，人们会根据线索的显著性和学习情况，以不同权重整合线索；或者，当差异较大时，他们会基于这些变量在不同线索之间进行选择（Cheng、Shettleworth、Huttenlocher和Rieser， ；Newcombe和Huttenlocher， ）。在一个旨在评估整合和选择的新范式中，迷失方向的参与者试图回到一个朝向方向，在一个梯形围栏中，特征和几何线索都明确地指明了一个朝向，但后来特征被移动了。当差异大于90度时，参与者选择几何线索。当差异较小时，在五种情况中有三种出现了整合；否则，参与者仅使用几何线索。变化取决于特征移动的方向以及最近的角是锐角还是钝角。这些结果对于对比适应性组合理论和模块化理论以及未来的研究具有启示意义，为重新定向研究提供了一种新范式，也为更广泛地测试线索整合提供了依据。
