Cox regression models examined associations between 17 indicators of psychological functioning (intellectual abilities, personality, subjective well-being, and social relations) and mortality. The sample (N = 516, age range 70-103 years) comprised participants in the Berlin Aging Study assessed between 1990 and 1993. By 1996, 50% had died. Eleven indicators(More)
This study tested the hypothesis that time spent on social activities (i.e., in direct interaction with others) and time spent in social contexts (i.e., while others are present) is associated with survival in persons aged 70 and older. An observational study with mortality follow-ups was carried out in the former West Berlin, Germany (Berlin Aging Study).(More)
This article surveys supervisors’ ratings, analyzes of piece-rates and employeremployee datasets as well as other approaches used to estimate how individual productivity varies by age. The causes of productivity variations over the life cycle are addressed with an emphasis on how cognitive abilities affect labor market performance. Although wage profiles(More)
Recent trends in German life expectancy show a considerable increase. Most of this increase has resulted from decreasing mortality at older ages. Patterns of oldest old mortality (ages 80+) differed significantly between men and women as well as between East and West Germany. While West German oldest old mortality decreased since the mid 1970s, comparable(More)
Using data from Germany, we examine if month of birth influences survival up to age 105. Since age reporting at the highest ages is notoriously unreliable we draw on age-validated information from a huge age validation project of 1487 alleged German semi-supercentenarians aged 105+. We use month of birth as an exogenous indicator for seasonal changes in the(More)
OBJECTIVE The study was conducted to examine sex differences in the initial level and rate of change in physical function and grip strength. METHOD The baseline survey included 2,262 Danes born in 1905 and alive in 1998 and followed-up in 2000, 2003, and 2005. Hence, the authors fully used the power of having a cohort with multiple assessments in late(More)
OBJECTIVE This study tested the hypothesis that time spent on activities that are considered regenerative (e.g., resting), productive (e.g., housework), and consumptive (e.g., meeting friends) is associated with survival in persons aged 70 and older. METHODS An observational study with mortality follow-ups was carried out in the former West Berlin,(More)
In a longitudinal sample of Moscow children and adolescents (grades 2–11; n = 434, tested in 1990, 1992, and 1994), we examined the interrelations between their action-control beliefs about school performance and their actual school performance. A notable feature of this sample is that the students were exposed to an educational context that is relatively(More)
