Behavioral data in the competitive game. (A) Hit rate for the first shot (mean ± SEM). Data were normalized by the arcsine transformation before statistical analyses. One-Way ANOVA demonstrated significant differences in the first-shot hit rate among the three types of trials [monkey H, F(2, 294) = 488.2, p < 10−93; monkey S, F(2, 471) = 61.7, p < 10−23; monkey P, F(2, 768) = 120.8, p < 10−45]. Post hoc paired comparisons were conducted using a Bonferroni-corrected two-tailed t-test (*p < 0.05). Monkey H, n = 99; Monkey S, n = 158; Monkey P, n = 257. (B) Latency of the first shot (mean ± SEM). Means of the median in each session were compared among the trial types. One-Way ANOVA demonstrated significant differences in latency among the three types of trials [monkey H, F(2, 294) = 53.4, p < 10−19; monkey S, F(2, 471) = 60.2, p < 10−23; monkey P, F(2, 768) = 105.9, p < 10−40]. Post-hoc paired comparisons were conducted using a Bonferroni-corrected two-tailed t-test (*p < 0.05). Monkey H, n = 99; Monkey S, n = 158; Monkey P, n = 257.
