Table 4. Mistakes.
Mean and standard errors are reported. Superscripts within target face age indicate statistical significance at p<.05. Mistake rates were computed for familiar faces and faces seen only once during scanning; estimates were missing for 3 participants (1 in the young cohort and 2 in the elderly cohort).
