q2 i2 In old high performers, CNV and P2/N2 amplitudes correlated significantly in blocks 1 and 2, but not in block 3 or in other groups. → Patrick D. Gajewski 2020

q2 · i2 · associational · r2

Pearson correlation analyses between preparatory CNV and target-locked P2/N2 amplitudes for each group and condition. "the high performing elderly showed a signi ficant correlation between the CNV and P2/N2" in blocks 1 and 2 (r = 0.28 to 0.51), with no significant correlations in young, middle-aged, old middle or old low performers.

"the high performing elderly showed a signi ficant correlation between the CNV and P2/N2 in the congruent and incongruent trials in block 1 (both r's ¼ 0.28; p < .05) and even stronger in block 2 ( r ¼ 0.40; p < .005 and r ¼ 0.51; p < .001), whereas no relationship was found in block 3."
