Extended Data Fig. 2: Detailed relationships between choice accuracy, RT, and confidence.
From: Neural basis of concurrent deliberation toward a choice and confidence judgment
a, Accuracy as a function of RT quantile, split by motion strength (% coh); error bars represent ±s.e.m. centered around the mean. Accuracy decreased as a function of RT for every individual motion strength except 0% in both monkeys and 51.2% in monkey G (monkey H, from lowest to highest motion str.: one-sided Cochran-Armitage test, Bonferroni-corrected α level = 0.0083; P = (0.1974, 0.0014, 8.2096 × 10−6, 1.7365 × 10−5, 0.0019, 0.0008), T = (−0.8991, −4.8591, −10.4087, −10.9343, −6.0227, −5.0061), N = (15761, 14838, 15626, 15827, 10944, 17028); monkey G: P = (0.0240, 0.0065, 0.0005, 1.0224 × 10−5, 0.0002, 0.0095), T = (2.2883, −3.931, −6.0409, −11.9857, −7.1641, −4.6287), N = (15761, 14838, 15626, 15827, 10944, 17028)). b, Confidence (proportion of trials with a high bet) decreased as function of RT. Error bars represent ±s.e.m. centered around the mean. Colors and order of statistical values as in a (monkey H: one-sided Cochran-Armitage test, P = (1.0987 × 10−4, 3.2480 × 10−5, 4.4356 × 10−6, 0.0019, 0.0054, 0.0234), T = (−6.9574, −9.8006, −11.4179, −3.8537, −4.5103, −2.8434), N = (17028, 12760, 11970, 13296, 10708, 7695); monkey G: P = (1.6467 × 10−10, 1.2407 × 10−8, 1.1916 × 10−8, 1.4939 × 10−8, 1.4052 × 10−7, 0.1305), T = (−36.7529, −37.2921, −37.5446, −36.1511, −18.9731, −1.3814), N = (13769, 15761, 14838, 15626, 15827, 10944)). c, Accuracy as a function of motion energy. Colors represent RT quintiles. Significant increases in accuracy were observed across all RT quintiles for both monkeys (interaction term between motion energy and RT quintile using ANCOVA, monkey H: P = 3.0838 × 10−12, F(4, 84131) = 14.9735, N = 84141; monkey G: P = 9.2056 × 10−15, F(4, 117391) = 17.9693, N = 117401). Error bars represent +/− s.e.m. centered around the mean. d, Confidence as a function of motion energy. Colors same as in c (interaction term between motion energy and RT quintile using ANCOVA, monkey H: P = 3.2351 × 10−04, F(4, 70175) = 5.24, N = 70185; monkey G: P = 0.0056, F(4, 94158) = 3.65, N = 94168).
