AbstractThis study aimed to assess the effects of aging on mind wandering (MW) using a sustained attention to response task (SART) with a low cognitive demand. All task-unrelated thoughts (TUTs) and the subcategory of stimulus-independent thoughts (SITUTs) were examined across the adult life span. The relationship between MW, cognitive variables (attention, inhibition, working memory), and non-cognitive variables (mindfulness, psychological well-being, and anxiety) was investigated. The sample included 210 healthy participants from 20 to 89 years old. The overall results showed few or no age-related changes in both TUTs and SITUTs. Path analyses revealed that the effect of age on both TUTs and SITUTs was only indirect and mediated by attentional resources, as well as by some aspects of psychological well-being (i.e., emotional competence), which had a direct effect, however. These findings raise doubts about any age-related differences between young and older adults’ MW. Changes in MW across the adult life span are thus discussed along with the method and tasks used to assess it and different variables affecting it.

Abstract Background Cortisol is a key stress hormone implicated in the pathogenesis of many age-related diseases. Longitudinal information on cortisol exposure has been restricted to animal models and a small number of human studies. The purpose of the present study was to quantify longitudinal change in cortisol across the adult life span. Methods We conducted a prospective longitudinal study of 24-hour urinary free cortisol excretion from ages 20 to 90 years and older. Participants were 1,814 men and women from the Baltimore Longitudinal Study of Aging who provided a total of 5,527 urine specimens for analysis. The average duration of longitudinal follow-up was 6.6 years. The primary outcome measure was 24-hour urinary free cortisol to creatinine ratio (UFC/Cr) as determined by liquid chromatography/mass spectrometry. Results UFC/Cr follows a U-shaped pattern across the life span with decreases in UFC/Cr in the 20s and 30s, relative stability in the 40s and 50s, and increases thereafter. This pattern of change was robust with respect to adjustment for several potential confounding factors. Conclusions Age-related changes in cortisol exposure raise important questions about the potential protective or exacerbating role of cortisol exposure in predicting medical, physiological, and behavioral outcomes.
