Addiction Due to the effect of reward cues and<unk>  on the amplification of incentive salience for rewarding stimuli, PIT is believed to be one of the mechanisms responsible for producing "cue-triggered wanting", or craving, for a drug that occurs when an individual with a drug addiction is exposed to drug cues even after long periods of abstinence. For example, anti-drug agencies previously used posters with images of drug paraphernalia – which is a type of drug cue – as an attempt to show the dangers of drug use. However, such posters are no longer used because of the effect of incentive salience in causing cravings and relapse upon sight of the stimuli illustrated in the posters. Dieting The sight or smell of food which one has consumed and enjoyed in the past can elicit hunger (i.e., the motivation to eat) in humans, an effect which is presumably mediated through PIT. In PIT experiments with rats, the presentation of a conditioned stimulus which has been paired with food has been shown to increase<unk>  actions that have been reinforced by food, such as pressing a lever which leads to the delivery of a food pellet.
