Furthermore, including working memory capacity as a covariate in the ANOVA reported above, the age group effect dropped to F (2;120) = 0.08, p > .91, η 2 = .001, while the effect of working memory capacity was highly significant, F (1;120) = 21.82, p < .001, η 2 = .154, and the other main effects and interactions remained nonsignificant.
