在使用地标的复杂导航中，动物必须区分潜在的线索并表现出对上下文(条件)的敏感性。这种条件性辨别被认为是一种复杂的学习形式，主要与脊椎动物有关。我们测试了章鱼和乌贼具有条件性辨别能力的假设。受试者在两种迷宫配置(条件)下接受训练，要求他们在每个迷宫中选择两条特定逃生路线中的一条(辨别)。在每个迷宫中选择正确的逃生路线可以证明条件性辨别。10只平底章鱼中的6只(章鱼)、13只法老乌贼中的6只(法老乌贼)和4种常见乌贼中的1只(药用乌贼)成功地解决了这两个迷宫，表现出条件辨别能力。这些实验证明，头足类具有条件辨别能力，并扩展了无脊椎动物复杂学习的范围。
In complex navigation using landmarks, an animal must discriminate between potential cues and show context (condition) sensitivity. Such conditional discrimination is considered a form of complex learning and has been associated primarily with vertebrates. We tested the hypothesis that octopuses and cuttlefish are capable of conditional discrimination. Subjects were trained in two maze configurations (the conditions) in which they were required to select one of two particular escape routes within each maze (the discrimination). Conditional discrimination could be demonstrated by selecting the correct escape route in each maze. Six of ten mud-flat octopuses (Octopus bimaculoides), 6 of 13 pharaoh cuttlefish (Sepia pharaonis), and one of four common cuttlefish (S. officinalis) demonstrated conditional discrimination by successfully solving both mazes. These experiments demonstrate that cephalopods are capable of conditional discrimination and extend the limits of invertebrate complex learning.
