Relationship between best-response behaviours and actual decision time. We analyze the data by classifying the 11 groups into 4 categories depending upon the experimental settings, namely, T1-T2 (large groups with 45 seconds maximum time allowed), T3-T4 (median groups with 30 seconds maximum time allowed), T5-T9 (small groups with 45 seconds maximum time allowed) and C1-C2 (large groups with 45 seconds maximum time allowed). Plotting proportion of best-response behaviours as a function of actual decision time in the 4 categories shows a clear positive correlation. The line is the result of linear regression by using the least squares approach. Error bars denote mean ± s.e.m.
