Behavioral performance. (A) Proportion correct categorization of offset- and onset-category exemplars in the posttest. Hashed bars indicate mean performance across the trained exemplars experienced in the videogame. Solid bars indicate mean performance for novel exemplars withheld from training (i.e., generalization) in the experimental (blue) and control (red) groups. (B) Group average in-scanner videogame performance, as measured by the highest game level achieved. (C) Correlation of the videogame performance (highest game level achieved) and categorization accuracy for the novel offset- and onset-category exemplars. Pearson’s correlation r values are shown. Dashed lines in A and C indicate chance level (0.25) performance. Error bars indicate ±1 SEM. See SI Appendix, Fig. S1 for further analysis of behavioral error pattern differences across the experimental and control groups.
