All animals must move efficiently throughout their world. However, the mechanisms through which they accomplish this potentially vary among species. Previous work exploring the use of feature information and geometric information in movement through space has indicated that geometric information is commonly used and that some species sometimes also use feature information. Here, I investigated if a cold-blooded species, leopard geckos (Eublepharis macularius), would use geometric and/or feature information. In training, geckos learned to move to a correct corner within the box with a distinctive feature. In test when only geometric information was available, geckos chose either their assigned corner or its geometric opposite. In another test when feature information conflicted with geometric information, geckos did not use feature information and instead made choices consistent with using geometric information. This suggests geckos used geometric information preferentially to feature information in this experiment after both had been available throughout training when they were placed in conflict.

所有动物都必须在整个世界中高效移动。但是，它们完成此任务的机制可能因物种而异。先前探索在空间运动中使用特征信息和几何信息的工作表明，几何信息是常用的，某些物种有时也使用特征信息。在这里，我调查了冷血物种豹纹壁虎（Eublepharis macularius），将使用几何和/或特征信息。在训练中，壁虎学会了以独特的方式移动到盒子内的正确角落。在测试中，当只有几何信息可用时，壁虎选择了其指定的角或其几何相反的方向。在另一项测试中，当特征信息与几何信息冲突时，壁虎不使用特征信息，而是做出与使用几何信息一致的选择。这表明在整个实验过程中，当壁虎在冲突中都可以使用时，它们优先使用几何信息作为特征信息。
