How students’ beliefs about the limits, or not, of their willpower significantly influence their performance

Writing in the Conversation, Nigel Newton from the University of Bristol discusses new research on how students’ beliefs about the limits, or not, of their willpower significantly influence their performance.

We’ve all experienced those moments when we’ve been working really hard on a task, finally finish and feel like a well-deserved break so we grab a coffee and relax for a few moments. What goes through your mind next? Do you believe you’ve reached as far as you can go that day, or do you feel energised for the next task, believing that your powers to keep focused are not depleted?

Research led by psychologist Veronika Job at the University of Zurich and others shed valuable light on the question of willpower and a person’s beliefs about it. Job found that if people believe their willpower is limited – and that they have a certain amount of it that will be used up – it will impact on their performance, particularly when they feel under pressure.

Their research was based on the “limited theory” of willpower, in which some people believe it is limited and needs to be replenished. However, others believe the opposite – that willpower is not limited and that they can activate it when they want to.

Psychologists conventionally thought that people who thought their willpower was limited could become more productive by conserving their energies and being selective in how they self-regulated their behaviour. There has also been a belief that glucose intake can quickly restore someone’s belief that they can keep going, and that the waning of focus is mainly a product of fatigue.

Job’s research has overturned both of these assumptions. In her study, students with increasing course demands who thought their willpower was limited procrastinated more, ate more junk food and reported excessive spending compared with students who thought they had no limits on their willpower.

The research also showed that students who believed there were no limits to their willpower benefited from more demanding circumstances. These students appeared to perform better when having to work on several assignments due in close together. It seems as if they responded to increased pressure with greater engagement, whereas those who thought their willpower was limited found it more difficult to stay focused on a task and manage their independent study effectively as the demands increased. The evidence suggests that this difference is not influenced by academic ability.

Other research has shown that adults in work suffer the same kinds of negative consequences from holding a limited theory of willpower and that this also produces lower subjective well-being. It appears that these people don’t strive much towards their own personal goals – which would suggest they are much less likely to have “grit”.

Grit and self-regulation

Grit relates to a person’s ability to take ownership of a goal and strive toward it, even when difficulties and setbacks occur. It is associated with what’s called “cognitive control”, or “self-regulation”, the capacity to keep focus where you want it to be.

There is evidence that the same part of the brain which is used in self-regulatory behaviour is also used for managing harmful emotions. So the more grit a person has, the more likely they will be able to manage those emotions of frustration, discouragement and anger which can overwhelm a person’s thoughts.

Much research on grit has been concerned with identifying its characteristics and studying its relationship to performance – both academic and at work. The American psychologist Angela Lee Duckworth has shown how grit is an effective predictor of strong academic achievement, successful performance at work, and that people with more grit are less likely to drop out of teaching and military training.

What is less understood is how to help people who think they have a limited amount of willpower to change – and help those with low levels of grit become more gritty.

It takes time for someone’s grit to positively change. Developing other approaches to learning helps considerably. Research I am concluding in several schools also shows that organisational values and a school’s ethos appear to contribute to how children both approach learning and develop a sense of agency in their studies.

The more we begin to see that we can learn effectively and believe that our effort and stamina is not exhaustible, the more we develop resilience in the face of challenges.

One of the reasons we need to consider all these different approaches to learning together is because a sense of purpose is closely related to their development. People who have clearer long-term goals and positive aspirations for the future are better at growing resilience.

The recent research on willpower helps to show that we don’t need to and shouldn’t give in to self-imposed limits. This isn’t to say we can’t take a break during a busy work or study period. But that’s not because we’ve exhausted or depleted our powers to focus and achieve. The best way to stay engaged and increase our sense of well-being is to keep in mind the goals which inspire us and our inexhaustible resources to achieve them.
