Here you can see videos from two ten-year-old participants from our first study exploring throwing and catching performance in children.
These eye tracking videos help demonstrate the differences between what skilled and non-skilled participants do when performing tasks such as throwing and catching.
Notice how the skilled participant (top video) focuses their gaze (indicated by the red circle) at the wall before throwing, and then tracks the ball as it bounces before catching it. This steady fixation on the target before completing a task is what is known as Quiet Eye.
The second video is of a child diagnosed with DCD. In this case you can see that what they are looking at is unrelated to the information they need to complete the task. They don’t have a steady fixation to where they want to throw and they are unable to pick the ball up as it bounces. This has two implications: The initial throw is not accurate (they don’t look where they want to throw); and they are not close to catching the ball (they do not track the ball early and predict where it will end up, allowing their limbs to move in a way to intercept it).
