Introduction
Older adulthood is associated with greater reliance on adaptive emotion regulation strategies, such as acceptance and positive reappraisal (Although many cognitive functions are implicated in adaptive emotion regulation, some of the strongest empirical evidence supports the critical role of WM (Considering these findings, the primary goal of this study was to examine whether brain-based markers of WM performance were associated with the prioritization of an adaptive strategy (acceptance) compared with a maladaptive strategy (suppression) during a behavioral task of emotion regulation. Despite limited research on the association between cognitive control metrics and the use of acceptance-based strategies, our prior work has evinced support for WM as an important moderator of mindfulness-based gains on attentional control and emotion dysregulation (Given that complex psychological processes, such as emotion regulation, are supported by multiple brain regions, functional magnetic resonance imaging (fMRI) researchers are shifting away from a focus on select cortico-subcortical regions and toward harnessing the variance distributed across the connectome to identify brain-based signatures of such emergent constructs. Connectome-based predictive modeling (CPM; Importantly, because aging is associated with declines in WM (As such, the current study will use the wmCPM networks derived from
