This chapter examines the origins of the construct of timescales as expressed in Waddington's (1957) metaphor for development of the epigenetic landscape, and its subsequent use as a metaphor for change in learning/development in theoretical frameworks, both connectionist and dynamical systems. It presents an epigenetic landscape model for motor learning and development, which is constructed as a low-dimensional approximation of a high-dimensional (or infinitely dimensional) complex dynamical system that possesses a score, error, or fitness function. The chapter concludes by illustrating briefly three case studies of the timescales of change in the epigenetic landscape framework to motor learning and development.
