AP PSYCHOLOGY

Detailed explanation-1: -The Minnesota Starvation Experiment ended in October 1945. Its results painted a vivid picture of the physical and psychological decline caused by starvation and offered guidelines on rehabilitation. In the restricted rehabilitation, calories were increased in increments.

Detailed explanation-2: -The Minnesota Starvation Experiment, as it was later known, was a grueling study meant to gain insight into the physical and psychologic effects of semistarvation and the problem of refeeding civilians who had been starved during the war.

Detailed explanation-3: -In 1944, a group of 36 healthy, male, conscientious objectors to World War II volunteered to be in this experiment conducted by physiologist Ancel Keys and his colleagues at the University of Minnesota.

Detailed explanation-4: -By the end of the semi-starvation period, the volunteers’ BMRs had decreased by 40% from their baselines. Keys et al. (1950) suggested that this was due to the low caloric intake which reduced the body’s need for energy.
