Abstract
Restraint is more effective in producing gastric ulceration in rats if it is imposed at the peak of their activity cycle or if it is used with characteristically more active rats. That finding plus several additional behavioral characteristics of stress-ulcer-susceptible rats suggest that animals susceptible to stress-ulcers during restraint manifest an elevated level of activation. Hypotheses derived from such an assumption are supported in the behavioral study reported.
