In the article “Differential Encoding Mechanisms for Subsequent Associative Recognition and Free Recall,” by Bernhard P. Staresina and Lila Davachi, which appeared on pages 9162–9172 of the September 6, 2006 issue, some overlapping lettering was inadvertently left in Figure 4. The corrected Figure 4 is printed here.
Figure 4.
Free recall-specific effects. Encoding activation is significantly greater in these regions for subsequent F (blue) compared with both subsequent IR (green) and subsequent AR (red), without differing between IR and AR. Left column, Statistical parametric maps (T-maps) are superimposed on the coronal slices of the mean anatomical image across subjects. A, Left mid/dorsolateral prefrontal cortex,. B, Left inferior parietal lobule/intraparietal sulcus. Middle column, Time course data are shown for the peak voxel (A, −45, 21, 21; B, −39, −54, 57). Percentage signal change is graphed for each memory condition across 14 s (7 time points) after trial onset. Right column, Results from pairwise contrasts across memory conditions. Bar graphs reflect the mean of the β parameter estimates across subjects for each condition, averaged across all voxels in a given cluster. Error bars represent the SEM. *p < 0.05. Note that bar graphs are mainly shown here for confirmatory and illustrative purposes, because the analysis was specifically designed to reveal regions that show this statistical pattern of activation.
