We found that those older adults scoring higher in Recall Ability performed significantly better than those individuals in the low scoring group, F(1, 40) = 23.66, p < .001, ηp2 = 0.372, across both test formats (F < 1). This effect remained significant when Executive Function score was taken into account, F(1, 40) = 5.71, p < .05, ηp2 = 0.144. Similarly, we observed a significant difference in memory performance between the High and Low Executive Function groups, F(1, 40) = 11.07, p < .005, ηp2 = 0.217, across test formats (F < 1), and this effect remained when Recall Ability was included as a covariate, F(1, 40) = 4.35, p < .05, ηp2 = 0.100. In contrast, those older adults who scored high and low in Representational Quality did not differ with respect to overall memory performance (F < 1). Instead, we observed a significant Test Format × Group interaction, F(1, 40) = 4.42, p < .05, ηp2 = 0.100, which reflected a selective impact of Representational Quality on Forced Choice performance, t(40) = 2.07, p < .05, d = 0.638, which was not observed in Yes/No performance (t < 1). Critically, this interaction remained significant when Recall Score and Executive Function were included as covariates in the ANOVA, F(1, 40) = 4.12, p < .05, ηp2 = 0.098, indicating an impact of Representational Quality on Forced Choice performance even after the effects of recall and executive function have been accounted for.
