Abstract

Objective: The present study examined whether the effect of neuroticism on brain structure is moderated by behavioral adjustment. Background: Neuroticism is widely thought to be harmful to health. However, recent work using proinflammatory biomarkers showed that this effect depends on behavioral adjustment, the willingness and ability to adjust and cope with environmental contingencies, such as different opinions of others or unpredictable life situations. Here, we sought to extend this observation to "brain health" by testing total brain volume (TBV). Method: Using a community sample of 125 Americans, we examined structural magnetic resonance imaging of the brain and quantified TBV. We tested whether the effect of neuroticism on TBV was moderated by behavioral adjustment, net of intracranial volume, age, sex, educational achievement, and race. Results: Behavioral adjustment significantly moderated the effect of neuroticism on TBV, such that neuroticism was associated with lower TBV only when behavioral adjustment was low. There was no such effect when behavioral adjustment was high. Conclusion: The present findings suggest that neuroticism is not debilitating to those who constructively cope with stress. Implications are further discussed. [ABSTRACT FROM AUTHOR]

41. Chapter 26: the temporal dynamics of emotional responding: implications for well-being and health from the MIDUS

Author

Schaefer, Stacey M., Van Reekum, Carien M., Lapate, Regina C., Heller, Aaron S., Grupe, Daniel W., Davidson, Richard J., Ryff, Carol D., and Krueger, Robert F.

Abstract

In this chapter findings are reviewed from the MIDUS Neuroscience Project that underscore the value in examining the temporal dynamics of responses to brief emotional provocation for understanding linkages among emotions and factors contributing to health and well-being across the MIDUS study. This rich dataset has allowed the exploration of associations between individual differences in the affective chronometry of negative and positive emotional responses in vulnerable vs. resilient profiles. Findings from functional magnetic resonance imaging (fMRI) as well as electromyographic recordings (EMG) of the facial muscles to objectively measure emotional responses demonstrate that the temporal dynamics of emotional responses to affective stimuli are associated with aging, personality, psychopathology, stress exposure, biomarkers, and well-being. Overall, these findings suggest that variation in health and well-being are differentially predicted by specific temporal parameters of the emotional response, such as the magnitude of the immediate response to the presence of a stimulus (i.e., reactivity), residual activity and its duration after stimulus offset (i.e., recovery), as well as the change in response – or habituation - across repeated presentations of similarly-valenced stimuli. Besides the seemingly obvious import of recovering quickly from negative or unpleasant provocations, the chronometry of positive emotional responses appears to be particularly vital for determining how emotional processes may take a physiological toll or promote resiliency in the face of stress and disease. By examining such temporal dynamics in response to affective stimuli in MIDUS, a better understanding of the brain-behavior associations underlying emotion, and how emotions “get under the skin” to impact well-being and health across the lifespan is gained.
