Figure 2. A trial-by-trial analysis based on a big loss for deck B'.

(A) Comparison of losses in deck A' and deck B'. In deck A', loss cards are drawn frequently, whereas in deck B', loss cards are drawn infrequently, but include 6 big loss cards. (B) Persistence in the face of big losses from deck B': Relationship between number of big losses as a result of selecting from deck B' and number of intervening trials before selecting from the same deck B' after a big loss. Some participants tended to repeatedly select from deck B' even as they experienced big losses.
