Scatter plots showing the correlation between the changes of grand-averaged P300 ERP amplitude and (A) the change in the proportion of P300-absent trials (% trials with no ERP, not the number of trials), (B) the change in single-trial P300 amplitude mean, and (C) the change in latency SD. All correlations are statistically significant, suggesting that there are multiple mechanisms underlying the changes seen on the averaged ERP level. Dotted green lines indicate a 95% confidence band for the regression curve.
