Figure 1.
Schematic diagram of the n-back task, separately for each task load, and each task version.
Details about timing for stimulus and inter trial interval (ITI) are included.

Demographics and neuropsychological test results.
Figure 2.
Behavioral results comprised of mean RTs (bars) in milliseconds (ms) and accuracy scores (lines) in percentages (%) for young (black) and old (grey) adults.
Behavioral outcomes are presented, separately, for the 0-back and the 1-back load in the identity version and in the integrated version.

Grand average ERP plots for the midline electrodes for targets in the 0- and 1-back load, separately for the identity and integrated version, for young (black lines) and for old (gray lines) adults.
Fz, Cz and Pz are presented from top to bottom.
