Pe_C latency correlates with the timing of awareness. (A) Single-trial aware error Pe_C waveforms locked to the erroneous response, pooled across participants and sorted by Aware RT (black line). For visualization, trials were smoothed across bins of 30 trials with a Gaussian-weighted moving average. Note how Pe_C peak latency closely tracks Aware RT. (B) To minimize the effect of noise in the single-trial measures on the observed relationship, the pooled single-trials were again sorted by Aware RT and, through repeated iterations, averaged across bins of increasing size (1–60; see text for details). The variance in Aware RT explained by Pe latency (R²) increased with bin size up to approximately 25 trials. (C) Topographies and trial sortings (including average component waveforms) for a subset of four participants. R-values at inset refer to correlation coefficients between single-trial Pe_C latency and Aware RT for that participant.
