![]() It happens in the same way in drug addiction as it did for Pavlov’s dogs or as it might for ice cream. Scientist have found that classical conditioning also happens in drug addiction. This process of forming mental links between environmental cues and something that is highly motivating, such as a food you like, is called classical conditioning. The smell of strawberries becomes a cue that could cause you to start salivating at the thought of ice cream. For example, if you go to an ice cream shop a lot and it smells like strawberries, eventually you might come to form a mental link between the ice cream and the smell of strawberries. Over time, the dogs would begin to drool when they heard the cue rather than when they received their food. Pavlov found that he could train the dogs to drool following a particular cue, like the sound of a bell, by presenting the cue before giving the dogs their food. Ivan Pavlov was a physiologist studying the digestive system in dogs, when he noticed that the dogs would begin to drool (or “salivate”) when ordinary things happened around the time when food was coming. We hope that by better understanding how these mental processes work, better treatments can be developed to help people with drug and alcohol addiction. This means that it is important for scientists to study these cues. Scientists know that drug use can be triggered by cues in the environment that remind people of drugs, like certain places, objects, sounds, or smells. Instead of living their lives to the fullest, they are often going through cycles in which they use drugs for a while and then quit, over and over again. Another reason is that, even with the best available treatments, the majority of people with drug addiction will spend years recovering. One of the reasons drug addiction is so harmful is that young people are most at risk of addiction. ![]() ![]() Even after people with drug addiction quit, it is very common for them to crave the drugs that they used to take and to eventually relapse and use those drugs again. Over time, people with addiction might need to take more and more drugs and they can come to rely on drugs so much that trying to quit makes them really sick. Addiction involves drug use that a person finds very difficult to control, even as it creates problems for the person at school, work, and home. Introductionĭrug addiction is a mental disorder that hurts people with drug addiction, their friends, family, and wider communities. By studying the brain as these mental links are being formed or broken, researchers are learning about one of the things that keeps people from breaking their addictions, and they are improving the therapies available to help people who are addicted to drugs. These mental links can motivate people to seek out drugs even if they are trying to quit. In drug addiction, people experience cues and contexts and drugs around the same time and form mental links or associations between the cues/contexts and the drugs. These things are called cues and contexts. Today, scientists are still interested in understanding how sights, smells, sounds, and places can come to influence our behavior. Pavlov’s dogs became famous in 1927 for learning that the sound of a bell meant that food was coming.
