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.
所有动物在其生存环境中都必须高效移动。然而，它们实现这一目标的机制在不同物种间可能存在差异。此前研究探索了动物在空间中移动时使用特征信息和几何信息的情况，结果表明，几何信息通常被使用，而有些物种有时也会使用特征信息。在这里，我研究了一种冷血物种，豹纹守宫（Eublepharis macularius）是否会使用几何和/或特征信息。在训练中，守宫学会了移动到盒子内有独特特征的正确角落。在只有几何信息可用的测试中，守宫选择了它们被分配的角落或其几何相对的角落。在另一个测试中，当特征信息与几何信息冲突时，守宫没有使用特征信息，而是做出了符合使用几何信息的选择。这表明，在训练过程中都可以使用这两种信息后，当它们发生冲突时，守宫在这个实验中更倾向于使用几何信息而不是特征信息。
