金鱼（Carassius auratus）进行了不同的地方发现任务的训练，作为分析其编码的几何和环境的特征属性的能力的一种手段。结果表明，金鱼可以编码并使用几何和特征信息来导航。在类似于地图或关系的程序中训练的金鱼将两种类型的信息编码在一个单一的表示中。相比之下，在直接线索程序中训练的鱼开发了2个独立和竞争的策略。这些结果表明，空间布局和离散地标的几何属性是敏感的编码在一个maplike或关系系统，而不同的空间信息源编码在一个单一的和灵活的表示环境。
Goldfish (Carassius auratus) were trained in different place-finding tasks as a means of analyzing their ability to encode the geometric and the featural properties of the environment. Results showed that goldfish could encode and use both geometric and featural information to navigate. Goldfish trained in a maplike, or relational, procedure encoded both types of information in a single representation. In contrast, fish trained in a directly cued procedure developed 2 independent and competing strategies. These results suggest that the geometric properties of the spatial arrangement and discrete landmarks are sensitive to encoding in a maplike or relational system, whereas different sources of spatial information are encoded in a single and flexible representation of the environment.
