Note. Theshold p < .001, k=30, corrected. All indirect effects represent full mediation. After controlling for ab paths, no group -> BOLD associations were significant at p <.05. Better maintenance of representations among the control group was associated with greater activation in the lingual gyrus and other occipital areas, mirror neuron regions (IFG, Supramarginal gyrus, Postcentral Gyrus, dACC), and the frontal pole. Poor maintenance of representations among the BPD group was associated with greater activation in regions for abstract aspects of mentalization, including the precuneus, mPFC, temporal pole and insula, and the parrahippocampal gyrus.
