Fig. 5. Results of transfer tests with fish 1 (A) and fish 2 (B), in which the original objects were replaced by smaller but otherwise identical versions of them. The left lighter coloured bar of each pair gives the results with the small objects, the right darker coloured bar gives results with original sized objects. Same conditions as in Fig. 3, i.e. S–, which was used during training, was replaced by a novel object. Each bar depicts the choice frequency for the left object (S+) of each pair.
