Effects of Shock Intensity, Deprivation, and Morphine in a Simple Approach-Avoidance Conflict Situation

Abstract
The effects of water deprivation, shock level, and morphine on punishment-induced suppression of water drinking during a single conflict acquisition session were studied. Suppression of drinkometer-recorded licking was greatest with high levels of intermittent foot-shock for drinking, and suppression was reduced by morphine. Level of deprivation had no significant effect.
