成年人在长方形环境的图像中寻找目标。目标的位置相对于特征和几何线索是恒定的，但绝对位置在不同的试验中发生了变化。参与者很容易学会使用特征线索来寻找目标，但学习只使用几何信息是困难的。变形测试显示，参与者使用不同特征的颜色和形状来编码目标的位置。当正确和几何等效角上的特征被移除后，参与者可以使用距离特征来定位目标。当存在单个距离特征时，准确率保持在概率以上，但距离目标最远的特征产生的准确率低于距离目标较近的特征。接受过特征训练的参与者自发地对几何信息进行编码。然而，这种表示法不能经受住取向转换。
Adults searched for a goal in images of a rectangular environment. The goal's position was constant relative to featural and geometric cues, but the absolute position changed across trials. Participants easily learned to use the featural cues to find the target, but learning to use only geometric information was difficult. Transformation tests revealed that participants used the color and shape of distinct features to encode the goal's position. When the features at the correct and geometrically equivalent corners were removed, participants could use distant features to locate the goal. Accuracy remained above chance when a single distant feature was present, but the feature farthest from the goal yielded lower accuracy than one closer. Participants trained with features spontaneously encoded the geometric information. However, this representation did not withstand orientation transformations.
