Rats received electric shock that was preceded by either a warning signal, a series of signals forming an "external clock," or no signal at all. In all conditions, subjects which could avoid and/or escape shock developed less ulceration than, did yoked "helpless" animals which received exactly the same shock (through fixed electrodes wired in series) but had no control over shock. Presence or absence of a warning signal did, however, have an effect: A discrete warning signal reduced the… 
EFFECTS OF THE AMOUNT OF REQUIRED COPING RESPONSE TASKS ON GASTROINTESTINAL LESIONS IN RATS
TLDR
It is concluded that responsibility for the fulfillment of the lever-pressing shock termination produces gastroduodenal ulcers while shock alone does not and the validity of Brady's experiment could be questioned.
The Effect of Chronic Conflict on the Blood Pressure of Rats with a Genetic Susceptibility to Experimental Hypertension
TLDR
Rats with a genetic susceptibility to experimental hypertension were exposed daily for 13 weeks to a conflict situation that resulted in food deprivation and the application of electric shock, and a pattern emerged wherein subjects exposed to conflict usually exhibited the highest systolic blood pressures.
Effects of Acute Exposure to Stressors on Subsequent Avoidance‐Escape Behavior*
TLDR
How the results presented in this paper, as well as in succeeding papers, support the “motor activation deficit” explanation for certain avoidance‐escape deficits are discussed, defining the cases to which the explanation applies and discussing the neurotransmitters involved.
Learned helplessness: Theory and evidence.
\, SUMMARY In 1967, Overmier and Seligman found that dogs exposed to inescapable and unavoidable electric shocks in one situation later failed to learn to escape shock in a different situation where
Attenuation of gastric lesions by psychological aspects of aggression in rats.
: Rats that fought with each other in response to electric shock showed reduced gastric lesions in comparison with animals that received the same shocks alone so that fighting behavior did not occur.
Shock-induced fighting attenuates the effects of prior shock experience in rats
TLDR
It was observed that fighters, like controls, showed a reduced pituitary-adrenal response to novelty when a consummatory response was available, and that the reinforcement provided by performance of this consummatories reduced the ACTH response to shock and permanently altered subsequent responsiveness.
Effects of Chronic Exposure to Stressors on Avoidance‐Escape Behavior and on Brain Norepinephrine*
TLDR
The behavioral and neurochemical changes that were observed after the stressful conditions studied are consistent with the hypothesis that changes in avoidance‐escape responding following exposure to these stressful events are due to changes in brain noradrenergic activity.

Somatic Effects of Predictable and Unpredictable Shock
  • J. Weiss

TLDR
Results point up the importance of psychologic variables in affecting stress by showing that consequences of the same physical stressor can be markedly altered by psychologic factors such as predictability.
Plasma Corticosterone Response to Parameters of Electric Shock Stimulation in the Rat
TLDR
It was found that merely placing the animals in the experimental cage increased corticosterone levels, and these levels were further elevated as shock intensity and duration were increased.
Measurement of free corticosteroids in rat plasma: physiological validation of a method.
TLDR
In the hypophysectomized animals, large doses of highly purified FSH, LH, TSH, STH, α-MSH and arginine vasopressin have no effect on the corticoid levels.
Emotionally Induced Increases in Effective Osmotic Pressure and Subsequent Thirst
TLDR
Osmometric analysis revealed a rapid increase in serum osmolality during stress which may account for the emergence of thirst and disruption of eating in hypoosmotic rats.
Clinical and physiologic implications of the steroid-induced peptic ulcer.
TLDR
The increased frequency of peptic ulcer after the administration of steroids appeared to justify speculation that the link with performance-enhancing drugs was linked to increased stress and anxiety.
