An experimental investigation of the role of psychological factors in the production of gastric ulcers in rats.

Abstract

Systematic variation of electric shock, hunger, thirst and the approach-avoidance conflict which had previously been shown capable of producing gastric ulcers in rats indicated (a) conflict to be a significant variable, (b) hunger and shock to contribute significantly in interaction, (c) thirst to fail of significance, and (d) that though weight loss is significantly related to the hunger, thirst and shock variables, it was not directly related to ulcer formation.
