Figure 4. Regions showing significant correlations between implicit associative learning scores and neural response to predictability in (A) younger adults and (B) older adults at late training, using a combined mask of the bilateral caudate and bilateral hippocampus (anatomically-defined). The scatter plot is presented to visualize how individual differences in the (C) caudate and (D) hippocampus relate to individual differences in late implicit associative learning within each age group. Contrast estimates were extracted from the mean of activated clusters using MARSBAR (Brett et al., 2002) in younger and older adults.
