An opportunity to build your knowledge and skills and challenge your assumptions, one video clip at a time.
Each week I will post 1 or 2 tutorials each with a video clip which highlights an aspect of development, providing an opportunity to improve your ability to analyze movement using the most-up-to-date theories of motor learning.

Prone development 5-7 weeks: rolling from prone to supine
Most very young infants do not like being placed in prone and quickly figure out how to roll from prone to supine using complex coordination of the head, trunk and limb segments.
Two video clips of Will, aged 5 and 7 weeks, demonstrate the intentional, goal directed nature of the rolling actions. They also illustrate how Will explores different patterns of inter-limb coordination to initiate the movement. He also has learned to generate and control momentum.
In this tutorial you have the opportunity to observe how Will, over a period of two weeks, gains increasing control of the position of the trunk when he sits with support around the hips.
There are two lines of research into the development of postural control in sitting which provide insight into Will's ability to sit with support at this age.
