Correlation of shift and stay reactions was studied in rats in the process of singling out of the win-stay dominant. It was found that in rat which had no previous experience in receiving reinforcement in multi-arm maze, both the shifts and stay reactions were observed with the dominance of the shifts. In experienced rats formation of the win-stay strategy using a new direction required learning and had three stages: the stage of initial dominant, of displacements and of singling out a new dominant. Formation of a new protracted dominant of win-stay could be gradual (through formation of short-term dominants) or uneven. At repeated changes of the reinforcement place both the tendency to uneven transfer and delayed periods in formation of the protracted dominant were observed. |
