Sample individual data for two young adults and two older adults. Dotted lines represent individual discriminability data at the five levels of processing time; solid lines represent best-fit curves. Because each individual fit is estimated from a best-fit curve for the relevant age group, some curves fit the discriminability data better than others. A and B show the most exact fits for a young adult and an older adult, respectively; C and D show the least exact fits. R2 values indicate the quality of each best-fit curve regressed to the actual data set.
