Many studies have analyzed how to cope with these challenges. These outcomes suggest that DM-related amygdala activity and/or emotion-related personality characteristics may provide utility as an endophenotypic marker of individual’s financial savings behavior.Įxperts worldwide point to the challenges our world is facing (e.g., land degradation, resource scarcity, global warming) as described by the Intergovernmental Panel on Climate Change. In exploratory analyses, this mediation was moderated by emotion-related personality characteristics such that, only individuals reporting lower alexithymia demonstrated a relationship between amygdala activity and savings. That is, elevated amygdala activity was linked with BART strategic-DM which, in turn, was linked with more money saved after 6 months.
Regarding brain-behavior relationships, we found that laboratory-based BART performance mediated the impact of amygdala activity on real-world behavior. Regarding BART-related brain activity, we observed expected activity in regions implicated in reward and emotional processing including the amygdala. Participants also completed self-report instruments characterizing relevant personality characteristics and then engaged in a community outreach financial program where amount of money saved was tracked over a 6-month period. Participants (N=24, 14 females) from low-SES households (income<$20,000/year) underwent fMRI scanning while performing the Balloon Analogue Risk Task (BART), a DM paradigm probing risky- and strategic-DM processes. As such, we examined the relationships between brain activity during decision-making (DM), laboratory-based task performance, and money savings behavior. Despite evidence suggesting a role for financial growth in minimizing SDoH-related disparities and vulnerabilities, neurobiological mechanisms linked with financial behavior remain to be elucidated. SDoH including low socioeconomic status (low-SES) influence cognitive abilities as well as health and life outcomes that may perpetuate poverty and disparities. Lower financial savings among individuals experiencing adverse social determinants of health (SDoH) increases vulnerabilities during times of crisis.
