Discussion
The current study examined whether whole-brain networks of WM derived from young adults using CPM generalized to predict WM performance, acceptance use, and emotion regulation difficulties in an independent sample of healthy older adults. We also sought to assess whether WM network strength moderated the relationship between image intensity and acceptance use. Consistent with our hypotheses, functional connectivity strength in the combined-WM network was positively associated with 2-back accuracy in our sample of older adults. In contrast to our hypothesis, the wmCPMs did not successfully predict acceptance use during an emotionally evocative behavioral task. Although experimental studies identifying specific cognitive and neural processes underlying acceptance use are relatively non-existent, some theoretical accounts suggest that acceptance falls within the broad category of cognitive change strategies alongside reappraisal-based strategies (Prior studies have also found that one’s preferences for and ability to implement cognitive change strategies, namely reappraisal, are moderated by stimulus intensity and WM abilities (
