Extended Data Fig. 2: Pre-goal attention lapses relate to canonical neural signals of recollection- and familiarity-based memory as assayed by grand-average left-lateralized Parietal Old/New and FN400 ERP effects, respectively.
From: Memory failure predicted by attention lapsing and media multitasking
a, Evidence of a peak Parietal Old/New signal (indicated by the black arrow) in the 500–600-ms post-probe window as a function of memory outcome in conceptual and perceptual source-retrieval trials. b, Trial-level interaction between pre-goal attention lapses and the Parietal Old/New signal during remembered (source hit) and forgotten (miss) trials. c, Evidence of a peak FN400 signal (indicated by the black arrow) in the 400–500-ms post-probe window as a function of memory outcome in novelty-detection trials. d, Trial-level interaction between pre-goal attention lapses and FN400 signal on correctly endorsed new items (hits) compared with misses. For visualization, quintiles are shown for the relationship between pre-goal lapsing and ERP signal; statistics included an interaction term for retrieval goal state (for Parietal Old/New) and treated pre-goal lapsing and the ERP signals continuously in trial-level mixed models. y-axis units are z-scores. Data are mean ± s.e.m. Note that z-scoring within run and time-binning in 0.1-s (100-ms) intervals reduces smaller temporal effects that are sometimes exhibited in grand-average ERP plots (for visualization of grand-average ERP plots downsampled to 0.01-s intervals (10-ms), see Extended Data Fig. 4). CRold, correct rejection of old item; CRnew, correct rejection of new item; FAold, false alarm to old item; FAnew, false alarm to new item. n = 75 participants from a single independent experiment.
