Examples of simulated SCRI visual neuron input and associated GAM accumulator trajectories on fast (0.2 RT quantile), medium (0.5 RT quantile), and slow (0.8 RT quantile) trials. Simulated trials are for monkey F. Trajectories are averaged over 10 trials centered on the corresponding RT quantile. Note that the “slow” trajectories in the Hard condition illustrate a case where a distractor had initially accrued activity in its associated GAM accumulator, leading to a slow response because of the time needed for the target accumulator to accrue enough activity to overwhelm the distractor accumulator.
