"This study investigated the learning by the rat of a modified Lashley Maze III adapted for swimming as a function of the combination of a relevant drive--escape from water--and an irrelevant drive--hunger--resulting from food deprivation. Two levels of relevant drive were produced by using water temperature of 15°C. (high) and 35°C. (low). The irrelevant drive was induced by 0-hr. and 22-hr. food deprivation. The addition of a high irrelevant drive to both high and low levels of relevant drive resulted in an increased total drive strength as measured by swimming time and error elimination."
