Mihalyi Csikszentmihalyi (pronounced chick-sent-me-high-ee), former Professor of Pyschology at the University of Chicago , has contributed a theory that is oft quoted in learning and hugely influential. His concept of ‘flow’ postulates mental states of optimal performance where we are ‘in the flow’. This, he thinks, applies to many cognitive tasks such as sport, programming, writing and, importantly, learning. He asks us to take the experience of flow into consideration when designing and delivering formal and informal learning. But do his theories really apply to learning?
