The effect of vascular health factors on white matter microstructure mediates age-related differences in executive function performance.

Cortex 2021 May 25;141:403-420. Epub 2021 May 25.

The University of Texas at Dallas, School of Behavioral and Brain Sciences, Center for Vital Longevity, Dallas, TX, USA. Electronic address:

Even within healthy aging, vascular risk factors can detrimentally influence cognition, with executive functions (EF) particularly vulnerable. Fronto-parietal white matter (WM) connectivity in part, supports EF and may be particularly sensitive to vascular risk. Here, we utilized structural equation modeling in 184 healthy adults (aged 20-94 years of age) to test the hypotheses that: 1) fronto-parietal WM microstructure mediates age effects on EF; 2) higher blood pressure (BP) and white matter hyperintensity (WMH) burden influences this association.

Switching Gears: A Self-Regulatory Approach and Measure of Nonwork Role Re-Engagement Following After-Hours Work Intrusions.

J Bus Psychol 2021 Jun 9:1-17. Epub 2021 Jun 9.

BetterUp, 1200 Folsom Street, San Francisco, CA 94103 USA.

As employees' personal lives are increasingly splintered by work demands, the boundary between work and nonwork domains is becoming ever more blurred. Grounded within a self-regulatory approach and the executive control function of inhibitory control, we operationalize and examine nonwork role re-engagement (NWRR)-the extent to which individuals can redirect attentional resources back to nonwork tasks following work-related intrusions. In phases 1 and 2, we develop and refine a psychometrically sound unidimensional measure for NWRR aligned with the self-regulatory processes of self-control and interference control underlying inhibitory control.
