Abstract:
Twenty mice (Mus musculus), the second filial generation offspring from a C57BL/6 and DBA/2J cross, received spatial win-shift and win-stay water escape training within a mixed design in which all mice received both types of training. Acquisition under win-shift was superior to win-stay with respect to errorless trials and latencies regardless of the order in which the procedures were experienced. Win-stay responding did not exceed chance levels during any training phase. These data contradict the claim that win-stay training is the more easily acquired of the 2 acquisition strategies under aversive motivation.
