“Pre-to-post “ = (post – pre)/pre*100; “ pre-to-during “ = (during – pre)/pre*100
“RT-M”: reaction time mean, “-V”: variability. “P3amp”: P300 amplitude. “Sig.”: Significance Testing
*Correlation is significant at the 0.05 level (2-tailed). Correlation = Spearman Correlation
**Correlation is significant at the 0.01 level (2-tailed)
***Correlation is significant at the 0.001 level (2-tailed)
