Figure 2. Behavioral results.

The averaged bet size was plotted as a function of previous outcome (win vs. loss) and streak length (1 to 5), separately for the CG (A) and SG (B) conditions. The same result was plotted again by separating the streak into short (1) and long (> = 2) streaks, which clearly showed the outcome by agency interaction in the long streak (D), but not the short streak (C) condition. E & F: Reaction time as a function of previous outcome and streak length (short vs. long). (G) The correlation of the gambler’s fallacy effect (as measured by the difference between bet size after loss(es) than after win(s)) between the CG and SG conditions. (H) The switch pattern of subjects’ choices under the SG condition. The small bar on the top left of each plot indicates the within-subject error (w.s.e).
