Error rates of bounded WDMs for stimuli with unequal prior probabilities. Models are stimulated with μ = σ = b = 1, and probability of the positive alternative being correct p+ = 0.9. Data are averaged over 10,000 trials. (a) Error rates as functions of starting point X0 for large tc = 3s: solid vertical line indicates the optimal starting point predicted by Eq. 11. (b) Error rates as functions of tc for the starting point of Eq. 11, compared with the error rate for unbiased starting point X0 = 0. Note that error rates of the reflecting WDM with biased starting points approach that for X0 = 0 at large tc.
