Prior research has suggested three explanations why levels of voluntary engagement rise and fall over time within societies. A social structural explanation considers individual resources crucial for engagement and argues that a redistribution of those resources may bring about changes in...

Recent research has repeatedly demonstrated that well-being typically evinces precipitous deterioration close to the end of life. However, the determinants of individual differences in these terminal declines are not well understood. In this study, we examine the role of perceived personal...

The Motivational Theory of Life-Span Development (MTD) identifies motivational and self-regulatory strategies that people use to meet the challenges they face throughout life. The theory distinguishes control strivings related to goal engagement from those related to goal disengagement and goal...

How socio-cultural contexts shape individual functioning is of prime interest for psychological inquiry. Secular increases favoring later-born cohorts in fluid intelligence measures are widely documented for young adults. In the current study, we quantify such trends in old age using data from...

Personality is a powerful predictor of central life outcomes, including subjective well-being. Yet, we still know little about how personality manifests in the very last years of life when well-being typically falls rapidly. Here, we investigate whether the Big Five personality traits buffer (or...

Anticipating one's future self is a unique human capacity that contributes importantly to adaptation and health throughout adulthood and old age. Using the adult lifespan sample of the national German Socio-Economic Panel (SOEP; N 10,000, age range 18-96 years), we investigated age-differential...

Early investigations of the neuroticism by conscientiousness interaction with regards to health have been promising, but to date, there have been no systematic investigations of this interaction that account for the various personality measurement instruments, varying populations, or aspects of...

In addition to biological sex, gender, defined as the sociocultural dimension of being a woman or a man, plays a central role in health. However, there are so far few approaches to quantify gender in a retrospective manner in existing study datasets. We therefore aimed to develop a methodology...

Perceived control plays an important role in shaping development throughout adulthood and old age. Using data from the adult lifespan sample of the national German Socio-Economic Panel (SOEP; N 10,000, covering 25 years of measurement), we explored long-term antecedents, correlates, and...
