Figure 2
Proportion of go stimulus durations on go and stop trials.
Figure 3
Choice response accuracy on stop-failure trials across SSD.
Note: 95% confidence intervals are presented as gray confidence bands. Individual-subject datapoints are presented in blue with lower alpha.

Inhibition functions from the real ABCD data and four simulated models.
Figure 5
SSRT estimates from four generating models (slowed go processing, guessing, confusion, and independent race) across SSDs if we assume context independence.
Figure 6
Histogram of stop-signal delays.
Figure 7
The probability of different numbers of intervening go trials between successive stop trials in the ABCD dataset (dark shading) versus expected probability distribution if stop trials were equally probable on all trials (light blue shading).
Figure 8
Post-stop-signal slowing across the four quantiles of the ABCD stopping data.
Note: Error bars are 95% confidence intervals.
Figure 9
Average stop-signal accuracy (a) and stop-signal delay (SSD, b) across subjects for each of the 60 stop trials.
Note: 95% confidence intervals are presented as gray confidence bands.

Table 1
Rank correlations of SSRTs from the three alternative generating models (rows) with the independent race model across the three SSD determination methods (ABCDw = ABCD weighted, fixed, and tracking) and four SSRT standard deviation (SD) scales (85 ms, 25 ms, 5 ms, and 0ms).
