Table 3.

Mean percentage of errors self-corrected per participant within the matched older and younger groups (for errors that occurred at least 20 times in each participant group). Error bars show bootstrapped 95% confidence intervals for means (estimated using 1,000 re-samplings of the participant means with replacement).
