Sample-based estimates of h(t), S(t), and ca(t) aggregated across all participants in the classical measure, for the first 70 bins (or 7,000 ms) after item onset. Bin width equals 100 ms. Each column represents a different N-back condition (in ascending order). Blue lines represent Match trials, red lines non-Match trials. Dotted vertical lines represent median RT estimates for Match and non-Match trials. Note that the greyed areas in h(t) and ca(t) plots obscure remaining time bins that contain less than 5% of trials (S(t>T) = 0.05). This is to highlight the more informative left side of the distributions.
