Shown are Spearman partial correlations, adjusted for education. *p < 0.05, **p < 0.01, ***p < 0.001, bold values indicate significance. The number of participants playing each game varied due to patient dropout. ^aMoCA scores without correction for low education. ^bCould not be computed because one of the variables was constant. RT: reaction time; MoCA: Montreal Cognitive Assessment.
