Dr Keith Souter writes: Mobile phones have become an integral part of life. Many people have become habituated to them and have to have them on all the time.
In researching habituation I came across an interesting mathematical curio called Lewin’s Equation. It was first proposed by the psychologist Kurt Lewin in 1936. He stated that ‘behaviour’ is a function of the ‘person in their environment.’ The equation is thus: B = f(P,E).

Before Lewin proposed his equation it was believed that a person’s behaviour and habits were a result of what sort of person they were. People still often think that way about habits. For example, people might say ‘I can’t stop smoking or drinking, I have no willpower.’
But Lewin would say that your behaviour is a function of both your personality ‘and’ your environment. If you can’t give something up, it may be because you are surrounded by bad options or people whose behaviour reinforces your bad habits.
An effective way of getting Lewin’s equation to work for you, concentrating on the P, or personality, is to change your mindset. Basically, people with a fixed mindset believe that their abilities are fixed, so they can’t improve or break free. Growth mindset people believe they can improve and learn.
The E, or environment is everything around the person. Nowadays, we can include the digital environment, because there are so many triggers.
