The Benefits of Believing in Chance or Fate: External Locus of Control as a Protective Factor for Coping with the Death of a Spouse

The death of a spouse is an extremely stressful life event that consequently causes a large drop in life satisfaction. Reactivity to the loss, however, varies markedly, a phenomenon that is currently not well understood. Because lack of controllability essentially contributes to the stressful nature of this incident, we analyzed whether individual differences in the belief in external control influence the coping process. To examine this issue, widowed individuals (N = 414) from a large-scaled panel study were followed for the 4 years before and after the loss by using a latent growth model. Results showed that belief in external control led to a considerably smaller decline in life satisfaction and higher scores in the year of the loss. Thus, although usually regarded as a risk factor, belief in external control acts as a protective factor for coping with the death of a spouse.Locus of control, life satisfaction, latent growth model, subjective well-being, subjective indicators, family and networks

Stability and Change of Personality across the Life Course: The Impact of Age and Major Life Events on Mean-Level and Rank-Order Stability of the Big Five

Does personality change across the entire life course, and are those changes due to intrinsic maturation or major life experiences? This longitudinal study investigated changes in the mean levels and rank order of the Big Five personality traits in a heterogeneous sample of 14,718 Germans across all of adulthood. Latent change and latent moderated regression models provided four main findings: First, age had a complex curvilinear influence on mean levels of personality. Second, the rank-order stability of Emotional Stability, Extraversion, Openness, and Agreeableness all followed an inverted U-shaped function, reaching a peak between the ages of 40 and 60, and decreasing afterwards, whereas Conscientiousness showed a continuously increasing rank-order stability across adulthood. Third, personality predicted the occurrence of several objective major life events (selection effects) and changed in reaction to experiencing these events (socialization effects), suggesting that personality can change due to factors other than intrinsic maturation.. - Fourth, when events were clustered according to their valence, as is commonly done,. - effects of the environment on changes in personality were either overlooked or. - overgeneralized. In sum, our analyses show that personality changes throughout the life. - span, but with more pronounced changes in young and old ages, and that this change is. - partly attributable to social demands and experiences.personality development, Big Five, life events, stability, adulthood

Examining mechanisms of personality maturation: The impact of life satisfaction on the development of Big Five personality traits

Individuals are expected to mature with increasing age, but it is not yet fully understood which factors contribute to this maturation process. Using data of a representative sample of Germans (N = 14,718) who gave information about their Big Five personality traits twice over a period of 4 years, we identified satisfaction with life, which was reported yearly, as an important variable for explaining mechanisms and interindividual differences in personality maturation. Dual latent change models suggest that more satisfied (compared to less satisfied) individuals experience more positive changes in Emotional Stability, Agreeableness, and Conscientiousness and that positive changes in life satisfaction are associated with positive changes in personality. Furthermore, maturation processes were examined for individuals who faced a social role transition, namely, marriage, birth of a child, or entering the job market. Again, differential effects highlight the importance of life satisfaction for personality maturation

Everything under control? The effects of age, gender, and education on trajectories of perceived control in a nationally representative German sample

Perceived control is an important variable for various demands involved in successful aging. However, perceived control is not set in stone, but rather changes throughout the life course. The aim of this study was to identify cross-sectional age differences and longitudinal mean-level changes as well as rank-order changes in perceived control with respect to sex and education. Furthermore, changes in income and health were analyzed to explain trajectories of perceived control. In a large and representative sample of Germans across all of adulthood, 9,484 individuals gave information about their perceived control twice over a period of 6 years. Using LOESS curves and latent structural equation modeling, four main findings were revealed: (a) Perceived control increased until ages 30 to 40, then decreased until about age 60, and increased slightly afterwards; (b) The rank order of individuals in perceived control was relatively unstable, especially in young adulthood, and reached a plateau at about age 40; (c) Men perceived that they had more control than women did, but there were no sex differences in the development of perceived control; (d) Individuals with more education perceived that they had more control than those with less education, and there were slight differences in the development of perceived control dependent on education. Taken together, these findings offer important insights into the development of perceived control across the life span

Investigating contributors to performance evaluations in small groups: Task competence, speaking time, physical expressiveness, and likability

This study compared the impacts of actual individual task competence, speaking time and physical expressiveness as indicators of verbal and nonverbal communication behavior, and likability on performance evaluations in a group task. 164 participants who were assigned to 41 groups first solved a problem individually and later solved it as a team. After the group interaction, participants' performance was evaluated by both their team members and qualified external observers. We found that these performance evaluations were significantly affected not only by task competence but even more by speaking time and nonverbal physical expressiveness. Likability also explained additional variance in performance evaluations. The implications of these findings are discussed for both the people being evaluated and the people doing the evaluating

Stability and change in affective experience across the adult life span: Analyses with a national sample from Germany.

Using cross-sectional and longitudinal data from a national sample spanning the adult lifespan, age differences in anger and sadness were explored. The cross-sectional and longitudinal findings consistently suggest that the frequency of anger increases during young adulthood, but then shows a steady decrease until old age. By contrast, the frequency of sadness remains stable over most of adulthood and begins to increase in old age. In addition, the effects of age on happiness were investigated; the cross-sectional evidence speaks for a steady decrease in happiness across age groups, but within-person decline in happiness was only evident in old age. Together the findings provide further evidence for multidirectional age differences in affective experience and suggest that the overall quality of affective experience may deteriorate in old age

Putting the self in self-correction: findings from the loss-of-confidence project

Science is often perceived to be a self-correcting enterprise. In principle, the assessment of scientific claims is supposed to proceed in a cumulative fashion, with the reigning theories of the day progressively approximating truth more accurately over time. In practice, however, cumulative self-correction tends to proceed less efficiently than one might naively suppose. Far from evaluating new evidence dispassionately and infallibly, individual scientists often cling stubbornly to prior findings. Here we explore the dynamics of scientific self-correction at an individual rather than collective level. In 13 written statements, researchers from diverse branches of psychology share why and how they have lost confidence in one of their own published findings. We qualitatively characterize these disclosures and explore their implications. A cross-disciplinary survey suggests that such loss-of-confidence sentiments are surprisingly common among members of the broader scientific population yet rarely become part of the public record. We argue that removing barriers to self-correction at the individual level is imperative if the scientific community as a whole is to achieve the ideal of efficient self-correction
