Recognition memory performance. Corrected recognition (hit rate minus false alarm rate) is plotted separately by study condition (fixed vs variable) and test viewpoint (repeated vs novel). Control participants (dark bars) were significantly more accurate at recognizing test probes that were shown in a repeated viewpoint. Furthermore, the performance benefit for repeated-viewpoint test probes was greater for faces studied from the same (fixed) viewpoint compared with those studied from variable viewpoints. H.C.'s accuracy (red bars) was similar to that of controls for faces studied in the same viewpoint across blocks (fixed-repeat and fixed-novel), and worse than controls for faces studied in the differing viewpoints across blocks (variable-repeat and variable-novel). Error bars reflect the 95% CI of the control group mean.
