Figure 7. A model for the entire system .

A third decision unit for the B responses (blue) is added to the model shown in Fig. 6, and transient inhibition with a time‐constant of 67 ms acts on both the Stop and B units. When an A response occurs, the B unit is retriggered to generate the second saccade (C) that lands on the final position of the target. The values of μ and σ for each subject are taken directly from their performance in the control task.
