Type II signal detection analysis of wagering responses. (a) Predictions from the model output for the pattern of signal detection parameters ($d_w^{\prime }$, left-hand panel; c_w, right-hand panel) calculated using Table 1. Wagering efficiency ($d_w^{\prime }$) is expected to change as a function of Type I d′, but only slightly as a function of wager size; the wagering criterion (c_w) is expected to be affected by both wager size and Type I d′. (b) Type II signal detection parameters from the post-decision wagering task as a function of stimulus visibility and wager size. Error bars reflect standard errors of the mean.
