Susan, age 9, has played soccer for years. She used a straight-leg kick every time for a while, but recently she began to try to bend her leg more, depending on the type of kick. As a result, sometimes she makes errors and sometimes she has a superior kick. Just recently she has been able to execute many types of kicks with much greater success. What feature of developmental systems theory does this scenario illustrate?
◦ Change simultaneously occurs in several components.
◦ The child's motor system is permanently destabilized.
◦ The body must wait for environmental factors to kick in.
◦ The child's motor system is unstable for a while, but then self-organizes into a new system of action.
