Notes:

k = number of effect sizes; N = total sample size; r = mean estimate of uncorrected correlations; rho = mean estimate of corrected population correlation; SE rho = estimated standard error of rho. Overall board task performance for studies reporting separate effects for service task performance and control task performance was calculated by computing their mean using Fisher’s (inverse) z-transformation.
