Out of 27 variables of personality and behavioral features, only the following 3 variables significantly contributed to the memory vs. control classification: (i) harm avoidance representing internalizing traits and negative mood states as assessed by TPQ (Memorymean = 16.16; Controlmean = 12.61), (ii) uplift experience, indicating “feel good” aspects as assessed by DHU (Memorymean = 51.25; Controlmean = 58.99), and (iii) neuroticism, represented by dysregulated emotions and maladjusted behaviors as assessed by NEO (Memorymean = 59.00; Controlmean = 52.11), where higher scores mean more neurotic traits.
