We all know people with very different levels of motivation. Some will go the extra mile in any endeavour. Others just can’t be bothered to put the effort in. We might think of them as lazy – happiest on the sofa, rather than planning their latest project. What’s behind this variation? Most of us would probably attribute it to a mixture of temperament, circumstances, upbringing or even values.
But research in neuroscience and in patients with brain disorders is challenging these assumptions by revealing the brain mechanisms that underlie motivation. When these systems become dysfunctional, people who were once highly motivated can become pathologically apathetic. Whereas previously they might have been curious, highly engaged and productive – at work, in their social lives and in their creative thinking – they can suddenly seem like the opposite.
