Figure 3.

The relation between self-ratings of expertise and visual recognition scores. (A) Graph for naming the model, (B) graph for naming the manufacturer, and (C) graph for naming the decade of make. The (D) graph is for the weighted perceptual score. Data from healthy subjects are shown as small black dots, with lines representing the linear regressions; r-values are for the correlation for healthy subjects. Data from prosopagnosic patients are shown as large grey discs. The data point for R-IOT3 (a retired car mechanic) is marked by a grey disc with a dark ring, and that for two other more-expert prosopagnosic subjects, R-IOT4 and R-AT2, are marked by grey discs with a dot and a white cross, respectively.
