The plot of the latent predictor weights for each of the independent variables in the model and surface rendering for the second significant spatial pattern identified by sequential latent root testing during the encoding phase. See figure 1 for details of labeling and color conventions.

In the young subjects, this pattern was expressed in both the letter and the shape task. Pattern expression was negatively related to the CR scores in both the letter and shape tasks. This indicates that brain areas with negative weights showed increased expression with increasing levels of CR. Similar directionality of pattern expression was noted for the elders during performance of the letter but not the shape task, and the degree of pattern expression did not reach significance in the elders.
