To examine the development of feedforward control during manual tracking, 117 participants in 5 age groups (6 to 7, 8 to 9, 10 to 11, 12 to 14, and 15 to 17 years) tracked an accelerating dot presented on a monitor by moving an electronic pen on a digitizer. To remain successful at higher target velocities, they had to create a predictive model of the target’s motion. The ability to track the target at higher velocities increased, and the application of a feedback‐based step‐and‐hold strategy decreased with age, as shown by increases in maximum target velocity and decreases in number of stops between ages 6–7 and 8–9 and between ages 8–9 and 10–11. The ability to exploit feedforward control in a dynamic tracking task improves significantly with age.
