Figure 3. Configural choices are related to hippocampal BOLD responses both within- and across-subjects.

Figure 3

(A) Example anterior hippocampal (aHip) ROI. Anatomical ROIs were drawn for each participant in their native space. (B) AHip BOLD Responses track configural choice value. Trial-specific estimates of aHip BOLD responses during each choice were used to predict whether that choice was based on configurally or elementally learned values (Configural Choice Index). AHip was more active when participants made choices that reflected configurally as compared to elementally learned values in the Separable Task and marginally more active in the Inseparable Task. Error bars indicate the SE of the β estimate. (C) Individual differences in configural learning are related to BOLD aHip responses. Correlation between individual differences in configural vs. elemental learning and degree to which aHip tracks configural choice values. (D) Lateral Occipital Cortex (LOC) ROI. The ROI was generated with an anatomically constrained meta-analysis for object processing. (E) LOC BOLD responses track elemental choice value, but only in the Separable Task. Trial-specific estimates of LOC BOLD responses during each choice were used to predict whether that choice was based on configurally or elementally learned values (Configural Choice Index); negative betas indicate greater activity during elemental choices. Error bars indicate the SE of the β estimate. (F) Individual differences in elemental learning are related to LOC responses, but only in the Inseparable Task. Lines depict group-level linear effects +/− 2 SE.
