Aversion therapy is a type of behavioural therapy that can be used to help individuals break undesirable habits, such as smoking. It involves pairing an unpleasant stimulus (such as an electric shock or a bad smell) with the behaviour that the person is trying to eliminate (smoking). Over time, this conditioning can make the person feel sick or repulsed by the behaviour, reducing their desire to engage in it. Therefore, aversion therapy may be the most effective behavioural therapy technique to help Heather eliminate her smoking habit.
