Abstract
3 groups of 5 rats each were given daily bar-press training while 22.5 hr. water deprived. Each group always received the same reinforcement: 4%, 12%, or 36% sucrose. In counterbalanced order every S was given 5 different saline or water stomach loads, spaced at 1-wk. intervals. These were given an hour prior to regular training which followed as usual. Both water and saline loads depressed responding, and there was a significant interaction between loads and reinforcements. The only differential effect of sucrose reinforcements during training or testing came after a stomach load of 5% body weight of water.This publication has 8 references indexed in Scilit:
