Figure 2.

Schematic representation of trial procedure. An initial fixation period was followed by a random motion period consisting of randomly moving dots. Next, the stimulus period contained leftward or rightward global motion and lasted until the child reported the direction with a response box. If there was no response, the stimulus remained on the screen for 2500 ms. The stimulus remained on the screen for an offset period after the response or after the maximum stimulus duration was reached. Note that arrows (indicating movement) and dotted lines (marking the square stimulus region) are shown for illustrative purposes only. Figure
