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

class="figure-viewer-img"

Figure 4. Graph results for CR by performance groups. For global efficiency and transitivity measures, network densities are displayed on the x-axis from min = 20% to max = 40%, in steps of 1%. Between-group differences in the efficiency measures are displayed on the y-axis. Between-group differences are significant when the red circles fall out of the blue-shaded area. CR, cognitive reserve. HighPF+lowCR, high performance participants with low CR. LowPF+lowCR, low performance participants with low CR. HighPF+highCR, high performance participants with high CR. LowPF+highCR, low performance participants with high CR. n.s., non significant results (p>0.05).
