Van Braeckel K, Butcher PR, Geuze RH, Stremmelaar EF, Bouma A (2007) Movement adaptations in 7- to 10-year-old typically developing children: evidence for a transition in feedback-based motor control. Human Movement Science, 26(6):927-942      
We used a modified double-step pointing task to study movement adaptations in 7- to 10-year-old typically developing children. We found that the majority (63%) were able to optimally adapt fast, goal-directed visually-guided movements to a late change in target location meeting the requirements of speed and accuracy. A minority (35%) failed to meet the requirement of accuracy resulting in a less optimal adaptation. The results showed that the ability to adapt movements optimally develops before the age of 7 years in typically developing children. Literature proposes a transition in devel- opment of motor control around the age of 8 years. The present results replicate and extend this by suggesting that this transition affects the later phases of fast, goal-directed visually-guided move- ments rather than the early phases, such as movement programming and acceleration. Finally, the results indicate that the optimally adapted movements were the result of a specific strategy in which a specific component of movement execution was slowed on all trials. This suggests that 7- to 10- year-old typically developing children have developed implicit knowledge about which movement components are the most efficient to adapt
