Groups ISWD and NSWD were equally proficient in escaping across trials and Group ISW was slower.
Group ISWD, inescapable shock water deprived, and NSWD, no-shock water deprived, were deprived of water beginning 36 hours prior to exposure to inescapable shock or shock context, with 5-minute access to water per day.
Groups ISWD, NSWD, and NSW were equally proficient in escaping across trials and Group ISW was slower.
Because the rats in Experiments 1 and 3 were similarly treated with respect to water availability, the shock-elicited lever press data were combined across experiments for Groups ISWD and ISW.
Water deprivation for Group ISWD was the same as for that group in Experiment 3a.
