q2 i3 Participants with greater attentional modulation of P1 amplitude around 100 ms post-stimulus showed greater subsequent memory of encoded stimuli (R=0.45, p<0.05). → Gazzaley A 2012

q2 · i3 · review · r2

EEG study (Rutman et al.) using a delayed-response task with overlapping face and scene stimuli, reported via Figure 1 of the review. The correlation between early P1 modulation and subsequent memory was significant (R=0.45, p<0.05), supporting early filtering of distractors.

"Participants with greater attentional modulation of P1 amplitude (~100ms post-stimulus presentation) show greater subsequent memory of encoded stimuli (R=0.45, p<0.05)"
