传递性推理(TI)是从先前信息推断未知关系的能力。为了在非人类动物中测试传递性反应，在假设对训练后呈现不相邻对的情况下，传递性反应被检测到。一些哺乳动物、鸟类和纸蜂可以通过TI任务。虽然前人的研究表明，一些鱼类在社会背景下能够完成TI任务，但目前还不清楚鱼类能否通过TI任务。在这里，我们在更清洁的乌鱼(Labroids Dimidiatus)中进行了一项TI任务，它与各种客户鱼类和同种鱼类相互作用。因为他们是根据之前的直接和间接相互作用在清洁相互作用的背景下做出决定的，所以我们预测TI的能力对清洁鱼类是有利的。研究人员用四对视觉刺激对四条受试鱼进行了训练，训练时间为5个学期：A-B+、B-C+、C-D+和D-E+(正负分别代表奖赏和非奖赏)。经过训练，出现了一对新的鱼，BD(BD测试)，其中鱼选择D的频率比B更高。相反，强化历史并不能预测D的选择。我们的结果表明，清洁的鱼通过了TI任务，类似于哺乳动物和鸟类。尽管清洁鱼类传递性反应的机制尚不清楚，但这项工作有助于理解鱼类的认知能力。
Transitive inference (TI) is the ability to infer unknown relationships from previous information. To test TI in non-human animals, transitive responding has been examined in a TI task where non-adjacent pairs were presented after premise pair training. Some mammals, birds and paper wasps can pass TI tasks. Although previous studies showed that some fish are capable of TI in the social context, it remains unclear whether fish can pass TI task. Here, we conducted a TI task in cleaner wrasses (Labroides dimidiatus), which interact with various client fishes and conspecifics. Because they make decisions based on previous direct and indirect interactions in the context of cleaning interactions, we predicted that the ability of TI is beneficial for cleaner fish. Four tested fish were trained with four pairs of visual stimuli in a 5-term series: A-B+, B-C+, C-D+, and D-E+ (plus and minus denote rewards and non-rewards, respectively). After training, a novel pair, BD (BD test), was presented wherein the fish chose D more frequently than B. In contrast, reinforcement history did not predict the choice D. Our results suggest that cleaner fish passed the TI task, similar to mammals and birds. Although the mechanism underlying transitive responding in cleaner fish remains unclear, this work contributes to understanding cognitive abilities in fish.
