Figure 2.

Graphic depiction of the time course of activation on a filtering trial. Presentation of a target stimulus simultaneously triggered excitation of the target's perceptual representation and inhibition of memory representations of previous targets and distractors. The time to reach threshold is classification RT, modeled as the number of cycles t needed to satisfy the stopping rule, which was set in all simulations here to β = 1.0. Imagine moving the vertical threshold line progressively from left to right until β = 1.0. Where the line stops (β = 1.0) is the predicted RT on the trial.
