q3 i? The P2/N2 complex was consistently larger in old high than old low performers, with some conditions showing larger amplitudes than young adults. → Patrick D. Gajewski 2020

q3 · i? · associational · r2

Target-locked ERP analysis of the P2/N2 complex at FCz. A main effect of Group (ηp2 = 0.064) and a significant Group x Block x Congruity interaction (ηp2 = 0.026) showed "consistently larger P2/N2 in OH than OL", and specific conditions showed larger amplitudes in OH than YA or OM.

"Bonferroni corrected post-hoc tests yielded consistently larger P2/N2 in OH than OL ( /C0 6.2 vs. /C0 5.2 μV; p < .001), whereas the difference did not reach signi ficance for other group comparisons."
