Professor Bart Hoebel and his team in the Department of Psychology and the Princeton Neuroscience Institute have been studying signs of sugar addiction in rats for years. Until now‚ the rats under study have met two of the three elements of addiction. They have demonstrated a behavioral pattern of increased intake and then showed signs of withdrawal. His current experiments captured craving and relapse to complete the picture. "If bingeing on sugar is really a form of addiction‚ there should be

20th century‚ many people believed that animals AND PEOPLE learned through a process of conditioning. For example‚ there were laboratory studies where rats were trained to push a button when a light came on. Each time the rat did this‚ it was given a piece of food. After a while‚ the rat would push the button every time the light came on. The rat had learned to associate pushing the button with getting food. This theory became known as behaviorism.

Watson popularized the use of the white rat in experimentation. His dissertation in 1903 voiced his study of animal learning through experimentation on these white rats. In 1915‚ he began experimentation on humans. “Watson advocated extension of the objective methods used in investigating animal behavior to research with human subjects and‚ himself‚ began
