Figure 8. An illustration of a typical trial during MAT training.

First, target balls to be tracked are briefly identified with a black outline (left panel). The black outlines disappear, and all balls start to move in random directions (centre panel). The participant’s task is to track the target balls. During the tracking task, drifting Gabor targets appear on either the right or the left side. The participant’s task is to also discriminate Gabor motion direction. After 10 seconds, all balls stop moving and two are highlighted (right panel). The participant’s task is to identify which ball was among the target balls.
