Food deprivation

Food deprivation is a technical term used in medicine , behavioral biology and motivational psychology for the lack of food in an organism that is associated with a feeling of hunger .

In medicine, the model of food deprivation ( starvation model ) provides explanations for symptoms of anorexia nervosa such as hypotension , bradycardia , leukopenia or lanugo hair .

In behavioral biology, laboratory animals are often deprived of food in experiments in which food is used as a rewarding stimulus in order to increase the rewarding effect of the feed. The American psychologist BF Skinner pursued the behavouristic approach that behavior is learned through reactions to stimuli from the environment and carried out numerous animal experiments . According to Skinner, behavior can be fully explained by external experiences ( stimuli from the environment), by food deprivation and the use of food as an amplifier . Skinner interested in the externally visible behavior and the possibility of this through specific influences ( learning , training to change).
