Trajectories of episodic memory in midlife: Historical change from a cross-country perspective.

According to the Flynn effect, performance on cognitive ability tests has improved over the past decades. However, we know very little about whether such historical improvements generalize to middle-aged adults (aged 45-65) and differ across nations. We used harmonized data on episodic memory from nationally representative longitudinal panel surveys across a total of 16 countries (United States, Mexico, China, England, and countries in Continental, Mediterranean, and Nordic Europe).

Mastering the canvas of life: Identifying the antecedents of sense of control using a lagged exposure-wide approach.

Accumulating studies have documented strong associations between a higher sense of control and improved health and well-being outcomes. However, less is known about the determinants of increased sense of control. Our analysis used data from 13,771 older adults in the Health and Retirement Study (HRS)-a diverse, longitudinal, and national study of adults aged >50 in the United States.

Voice biomarkers in middle and later adulthood as predictors of cognitive changes.

Background: Prosody voice measures, especially jitter and shimmer, have been associated with cognitive impairment and hold potential as early indicators of risk for cognitive decline. Prior research suggests that voice measures assessed concurrently with longitudinal cognitive outcomes are associated with 10-year cognitive declines in middle-age and older adults from Midlife in the U.S.

The psychosocial anti-inflammatories: Sense of control, purpose in life, and social support in relation to inflammation, functional health and chronic conditions in adulthood.

Objective: Three psychosocial variables were examined as predictors of chronic inflammation, functional health, and number of chronic conditions.

Methods: This cohort study used the Midlife in the United States biomarker sample. Data were collected in 2004-2009 (M2) and 2013-17 (M3).

The Relationship Between 10-Year Changes in Cognitive Control Beliefs and Cognitive Performance in Middle and Later Adulthood.

Objectives: The present study used a cross-lagged panel design with longitudinal data to test if there is a reciprocal relationship between cognitive control beliefs and cognition (e.g., executive functioning and episodic memory) over 10 years, whether frequency of engaging in stimulating cognitive activities mediated this relationship, and if these relationships varied by age.
