THE PSYCHOLOGY OF HUNGER

Tre Kingsberry

Hunger motivation

Hunger is now known to be regulated on a short-term basis by two clusters of cells called nuclei

Body Chemistry and the Brain Hunger is controlled by the 2 parts of the

hypothalamus. The Lateral Hypothalamus brings in the

hunger. The Lower-Mid Hypothalamus

depresses hunger ( feeling full)

Taste Preference

Body chemistry and environmental factors influence when your hungry and what your hungry for.

Some taste preferences are culturally conditioned

The Set Point

The body has a weight regulatory system, which establishes a “set-point” that regulates body weight on a long-term basis.

Hunger Theories

Developed by Clark Hull in 1943 Drive theory is based on the principle

that organisms are born with certain psychological needs and that a negative state of tension is created when these needs are not satisfied

Drive Reduction- When the need is met the organism returns to a state of homeostasis and relaxation.
