Decrease in glucose levels means hunger levels increase‚ whereas an increase in glucose levels means satiation is reached. 2. Research has revealed two significant eating centres in the hypothalamus; the lateral hypothalamus (LH) and the ventro-medial hypothalamus (VMH). Research from the 1940s

Classical conditioning is involved with making an association with eating and anxiety. Therefore anorexics seek to lose weight/not eat to reduce their anxiety. Once this association has been made operant conditioning starts playing its part through negative and positive reinforcement

Biological Explanations of Criminal Behavior Nature and nurture contribute to the way a person behaves. This can be applied to the behaviors of criminals.
