Animals use a variety of cue types to locate and discriminate objects. The ease with which particular cue types are learned varies across species and context. An enormous literature contains comparisons of spatial cue use to use of other cue types, but few experiments examine the ease with which various nonspatial cues are learned. In addition, few studies have examined cue use in reptiles. Thus, the authors compared whiptail lizards' (Cnemidophorus inornatus) ability to learn and reverse a discrimination using either position (left or right) or visual feature cues. Lizards learned and reversed the task using position cues faster and with greater accuracy than using feature cues.
动物利用多种线索类型来定位和辨别物体。特定线索类型的学习难易程度因物种和环境而异。大量文献对空间线索的使用与其他线索类型的使用进行了比较，但很少有实验研究各种非空间线索的学习难易程度。此外，很少有研究考察爬行动物的线索使用情况。因此，作者比较了鞭尾蜥（Cnemidophorus inornatus）使用位置（左或右）或视觉特征线索进行辨别学习和反转学习的能力。与使用特征线索相比，蜥蜴使用位置线索学习和反转任务的速度更快，准确性更高。
