(A) Percent of included studies finding a AVG players (AVGPs) to outperform non-gamers (NGs) on tests of attention, memory, information processing and task-switching cognitive abilities. ‘n’ values represent the total number of included studies examining each cognitive ability. (B) Probability density functions for the true success rates of a study to find AVGPs to outperform NGs on tests of attention (black trace), memory (blue), information processing and task-switching (orange) ability, respectively. Shaded areas represent the probability (/100%) that the observed success rate, given the findings of the included studies, reflects the true success rate.
