Scatterplot of Continuous Performance Test-Identical Pairs version (CPT-IP) score (standardized; t-score) as predicted by SVM Model 1 across the full study sample (N = 52). Multiple regression explained 39 % of the variance in CPT-IP score based on frontal gamma activity during encoding and central theta 1 activity during retention for correct trials and occipital gamma activity at retrieval for incorrect trials. SVM Model 1 score (x-axis) represents the residual difference between predicted (trend line) and observed value for CPT-IP score
