Data from Experiment 2. Tracking accuracy as a function of set size. The blue line represents the raw accuracy in the experiment where Os could track for up to 8 s then guess the location of the target if they had not seen a state change. The green line represents the adjusted performance in which the trials were considered correct only when a correct response was made within 2 s after the target’s state changed. The dashed lines show the estimated performances from the model with guessing (orange) and without guessing (red). Error bars are ±1 SEM
