• This week's webinar goes beyond sport and applies to all kids at school and adults, no matter how good they are at sport.

Mental or Cognitive flexibility is an intrinsic property of a cognitive system often associated with the mental ability to adjust its activity and content, switch between different task rules and corresponding behavioural responses, maintain multiple concepts simultaneously and shift internal attention between them.

Since cognitive flexibility is a vital component of learning, deficits in this area might have other implications.

• Dr Kirsten van Heerden is one of only a handful of people in South Africa to have both represented her country as an athlete and also hold a PhD in the area of sport psychology. She has worked and travelled extensively within high performance sport for more than 10 years and her services have been used by many Olympians, World Champions and South African sports teams. Kirsten has a special interest in mental health in elite athletes and transition out of sport into normal life.
