Cognitive reserve and network efficiency as compensatory mechanisms of the effect of aging on phonemic fluency

Figure 2. Interaction between CR levels and age (A), and between CR levels and performance groups (B), in the prediction of phonemic fluency (ANCOVA). Bars represent the mean of words produced and the jack-knifes represent the 95% confidence intervals. Panel A represents the interaction between CR and age. Panel B represents the interaction between CR and performance groups. CR, cognitive reserve; YA, younger age; OA, older age; Low PF, low phonemic fluency performance; High PF, high phonemic fluency performance.
