Note. Predicted values of probabilities were generated from the diffusion model with partial information using the parameters in Tables 2 and 3. The hit rates from conditions 2, 3, and 4 were scaled against false alarm rates for condition 7 to produce d′ values. Exponential growth to asymptote functions were fit to the d′ functions with one time constant and three asymptotic d′ values and with three time constants and three asymptotic d′ values. The “Baseline condition” row above used the values of parameters in Tables 2 and 3 and the other rows differ only in the parameter shown (and with z = a/2 for the parameter a) from the values in Tables 2 and 3.
