Breaking bad habits: classical conditioning and smoking
Smokers find it difficult to quit because the environment is full of signals associated with smoking cigarettes. Sarah Horrigan
Addictions are difficult to break as we usually surround ourselves with people, paraphernalia or situations that trigger the behaviour that led to the addiction in the first place. But psychological conditioning can be used to break bad habits. Over a century ago, the Russian physiologist Ivan Pavlov made a discovery that still resonates with both psychological experiments and popular culture. Classical conditioning predicts that by repeatedly pairing a motivationally significant stimulus (such as food) with a particular signal (such as a ringing bell) will result in a conditioned response when the signal is encountered (the bell rings in absence of food). So the sound of a ringing bell will evoke a behavioral or conditioned response, such as salivation (initially elicited by the food stimulus). A previously neutral stimulus can evoke a particular behaviour through an association with an emotionally significant outcome. Pavlov found that after repeatedly pairing the food with the ringing bell his dogs would salivate just to the sound of the bell. This theory doesn’t just apply to drooling dogs but has formed an important rationale for the development, maintenance and relapse of drug-taking behavior’s. Drugs are rewarding in nature and act by increasing levels of the neurotransmitter dopamine in the brain. Under normal circumstances, dopamine is involved in maintaining behavior’s essential for survival, such as obtaining food and sex. Drugs also act on this system and the brain associates the rewarding high with the drug, motivating more drug taking. These systems become “hijacked” by the drugs of abuse, producing maladaptive changes that preserve addictive behaviours. Lighting up and learning
Nicotine, via tobacco, is one of the most heavily used addictive drugs in the word. In Australia, smoking is the leading preventable cause of death, killing about 15,000 people every year. Quitting smoking is difficult, and nicotine withdrawal symptoms include irritability, anxiety, difficulty concentrating and insomnia. Nicotine exerts physiological effects very rapidly. Nicotine from inhaling a cigarette reaches the brain in about 10 to 20 seconds and there it binds to nicotinic receptors on neurons. Stimulation of nicotinic receptors affect functions such as breathing and heart rate, and triggers the release of dopamine. So the rewarding effects of smoking are very rapid. And the association between smoking and its rewarding effect is very strong, and forms quickly. Classical conditioning theory predicts that drug-related stimuli can become associated with the rewarding aspects of using. These include drug paraphernalia (cigarette packets, syringes, bongs and pipes) and environments where drug taking occurs. These stimuli can evoke responses, such as craving and drug seeking, which is known as second-order conditioning.

Rklawton/Wikipedia Commons For smokers, just the sight of a cigarette packet can evoke the feeling of wanting to smoke. But this isn’t restricted to smokers and drug addicts. We form associations with all kinds of environmental stimuli and things we desire. Just looking at your smartphone, for instance, can create an urge to check email. These complex associations maintain behaviours and can also cause reinstatement when certain cues are encountered. This is why smokers find it so difficult to quit – the environment is full of signals associated with smoking cigarettes. Breaking the habit
A prescription medication treatment for smoking addiction isVarenicline (known as Champix in Australia, Canada and Europe and Chantix in the United States). Varenicline is a partial agonist at nicotinic receptors – it stimulates nicotine receptors more weakly than nicotine does. This reduces cravings for nicotine and decreases the satisfying effects of cigarettes because the receptors are already occupied with the varenicline molecules, so nicotine can’t exert its full effect. It decreases the rewarding effect of smoking and weakens the association between cigarettes and pleasure. Varencline has a success rate of about 22%, which is greater than Buproprion (Zyban), another smoking cessation aid. Butconcerns have been raised about the potential side effect of depression in both of these treatments. Another reported effect of varenicline in some people is nausea, which can reduce smoking more rapidly because the taste of tobacco becomes associated with nausea. This is calledconditioned taste aversion. Varenicline as a smoking-cessation treatment may seem extreme, but its rationale is firmly established in Pavlovian learning theory; a behavior will decrease when its reward is devalued. And if the behaviour becomes associated with something negative (such as feeling nauseous), it will occur even less. We are fortunate that advances in medicine offer smokers more choices than ever before to help them quit successfully. Some may seem more extreme than others but they’re all centered on breaking the nicotine habit.

1. What is the UCR, UCS, CR, CS in this article?
2. What was the solution that this article brought up in order to help decrease smoking?
3. In your opinion do you think this solution will work?
4. Imagine yourself as a psychologist and you were given a task to help people lose weight and stop over eating. Using classical conditioning how will you solve this problem.
1. Unconditioned Response: Smoking; Drug or nicotine intake
Unconditioned Stimulus: The craving for drugs or nicotine; a feeling of reward or pleasure Conditioned Response: associating nicotine with nausea or depression Conditioned Stimulus: taking medicinal drugs
2. A prescription medication called Varenicline. They probably just mentioned it to sell the drug more and maybe even make the people rely on the people at a specific point. 3. According to the article, it will only work 22% of the time. However, personally, I do not think that the drug will work because it seems as if the article’s writer was paid to advertise this drug.
That may not be what actually happened, but they’ve said it in a way that makes it seem as if they’ve deliberately put it there on purpose. 4. Losing weight is simple, not easy. It’s simple because you have to work hard and be dedicated to it. It’s not easy because not many people are actually willing to do that. Personally, I would just use mild hypnosis as a treatment which has proven to be a lot more effective than that of other drugs.
