Figure 8. ROI analysis of key verbal working memory regions through time.

Figure 8

Activity estimates (t-values) plotted for the early, mid and late delay period time phases (columns) for each rehearsal rate (x-axis) and memory load (different colors). Results demonstrate a reduction in load effects through time as all regions revealed a PHASE×LOAD interaction (all ROIs, parametric ANOVA: p<0.001). Conversely, rehearsal rate effects remained constant through time as no region demonstrated a PHASE×RATE interaction (all ROIs, parametric ANOVA: p>0.10). There was no LOAD×RATE interaction. Data plotted are group means. Error bars represent bootstrapped within-subject 95% confidence intervals.
