Extended Data Fig. 7: Additional reaction time and movement speed data and modeling of human data.

(a) Median reaction times for all responses, correct responses, and incorrect responses from the 16 mice used for Fig. 1b,c. Circles are means across mice and error bars represent standard error of the mean. (b) Comparison of median reaction times for correct and incorrect responses for each mouse. Each circle is data for one condition (mask onset or target only) from one mouse. (c) Cumulative probability distributions of reaction times pooled across the mice for correct (solid lines) and incorrect (dashed lines) responses. Reaction times on mask-only and catch trials are also shown. (d,e) Same as B,C for movement speed. (f-h) Same as A-C for the reaction times of 16 human subjects. (i) Fraction correct versus reaction time after pooling reaction times across all humans in 600 ms bins. Shaded region surrounding each line is the 95% confidence interval given the fraction correct values and the number of pooled trials for each bin (the median number of trials across mask onset conditions was 135, 296, 30, and 28 for the time bins from left to right after excluding conditions from a bin if there were less than 15 trials). (j-l) Response rate, accuracy, and reaction times of the dual accumulator model (open circles) shown in Fig. 3f fit to human behavior data (filled circles with error bars representing the standard error of the mean from 16 humans). (m) Accuracy versus reaction time for the model, corresponding to I for humans.
