You can hack your brain to form good habits — like going to the gym and eating healthily — simply by repeating actions until they stick, according to new psychological research involving the University of Warwick. Warwick’s Department of Psychology, with colleagues at Princeton and Brown Universities, have created a model which shows that forming good (and bad) habits depends more on how often you perform an action than on how much satisfaction you get from it. The researchers developed a computer simulation, in which digital rodents were given a choice of two levers, one of which was associated with the chance of getting a reward.
Much of what we do is driven by habits, yet how habits are learned and formed is still somewhat mysterious. Our work sheds new light on this question by building a mathematical model of how simple repetition can lead to the types of habits we see in people and other creatures. Psychologists have been trying to understand what drives our habits for over a century, and one of the recurring questions is how much habits are a product of what we want versus what we do.
Our model helps to answer that by suggesting that habits themselves are a product of our previous actions, but in certain situations, those habits can be supplanted by our desire to get the best outcome.”This research opens up a better understanding of conditions like Obsessive Compulsive Disorder and Tic Disorder — both of which are characterized by repetitive behaviors. The next stage will be to conduct similar experiments in a real-world scenario, observing human behavior in action-based versus reward-based tests.
