THE CAPABILITY FOR GENERALIZATION BY THE RELATIVE SIGN TOP POSITION IN BOTTLE-NOSED DOLPHINS

Bottle-nosed dolphins demonstrated the ability to distinguish the tap position of the objects in the process of learning. They always chase the top object From the three identical things under conditions of per manent location changing of this stimulus triplet an one of the sides of the water enclosure, Specialization of the reflex was tested under conditions of the stimulus triplet administration at the background of different situational changes in surroundings, including the changes in location of external reference points The animals retained the adeq uate reaction also after a sudden substitution of the initial stimulus objects for others which were considerably different from the initial stimuli in the shape, material, size etc. When the natural stimuli (t hree fishes) were presented of che number of the stimuli was substitut ed from 2 for 5, nevertheless, the dolphins chose the top stimulus, Th e findings testify to the capability of dolphins for generalization by the relative sign atop <<top position>>.
