Cross-sectional age differences and longitudinal age changes of personality in middle adulthood and old age

The present study examines different aspects of personality continuity (or change) in middle adulthood and old age both cross-sectionally and longitudinally. The sample comprised 445 middle-aged (42-46 years) and 420 older (60-64 years) participants, reassessed after a 4-year interval. Personality was measured using the NEO-FFI personality inventory. After having established strict factorial invariance, factor covariances were found to be equal for both age groups and at both testing occasions, indicating perfect structural continuity of personality. A number of age differences in personality emerged at both measurement occasions. Longitudinally, in both age groups, an average decline in Neuroticism was observed. Longitudinal stability coefficients were around .80 in middle-aged and old participants, implying high, but not perfect, differential continuity. With respect to continuity of divergence, statistically significant cross-sectional age differences were found for the variance of Openness at both measurement occasions. Eventually, concerning specific versus general continuity, a variety of medium effect-sized correlated changes in the Big Five personality domains across the 4-year period was established, implying that personality changes share a certain amount of commonality.     

Do agreeableness and neuroticism explain age differences in the tendency to forgive others?

Previous research has shown that age is positively related to a dispositional tendency to forgive others. The present investigation tested the hypothesis that agreeableness and neuroticism partially mediate the association between age and forgivingness. Data from two representative cross-sectional samples of adults were used to test this hypothesis. Results from Study 1 (N = 962, age range: 19-84 years) support the hypothesis, indicating that agreeableness and neuroticism explained, in part, age differences in tendencies to forgive. Study 2 (N = 451, age range: 20-83 years) replicated and extended the results by including transgression occurrences as a third mediator. The results showed that agreeableness and neuroticism explain the association between age and the tendency to forgive others over and above the effect of transgression occurrences.     

Self-Report and Observer Ratings of Personality Functioning: A Study of the OPD System

Recent considerations around DSM–5 criteria of personality disorders (PDs) demand new concepts of assessing levels of personality functioning. Of special interest are multiperspective approaches accounting for clinicians’ as well as patients’ points of view. The study investigates observer-rated and self-assessed levels of personality functioning measured by the level of structural integration as defined by the Operationalized Psychodynamic Diagnosis System (OPD). Both perspectives were positively related. The combination of both measures was most efficient in discriminating among 3 diagnostic groups of varying degrees of personality dysfunction. Future studies should take into account expert ratings as well as self-report data.     

The roles of associative and executive processes in creative cognition

How does the mind produce creative ideas? Past research has pointed to important roles of both executive and associative processes in creative cognition. But such work has largely focused on the influence of one ability or the other—executive or associative—so the extent to which both abilities may jointly affect creative thought remains unclear. Using multivariate structural equation modeling, we conducted two studies to determine the relative influences of executive and associative processes in domain-general creative cognition (i.e., divergent thinking). Participants completed a series of verbal fluency tasks, and their responses were analyzed by means of latent semantic analysis (LSA) and scored for semantic distance as a measure of associative ability. Participants also completed several measures of executive function—including broad retrieval ability (Gr) and fluid intelligence (Gf). Across both studies, we found substantial effects of both associative and executive abilities: As the average semantic distance between verbal fluency responses and cues increased, so did the creative quality of divergent-thinking responses (Study 1 and Study 2). Moreover, the creative quality of divergent-thinking responses was predicted by the executive variables—Gr (Study 1) and Gf (Study 2). Importantly, the effects of semantic distance and the executive function variables remained robust in the same structural equation model predicting divergent thinking, suggesting unique contributions of both constructs. The present research extends recent applications of LSA in creativity research and provides support for the notion that both associative and executive processes underlie the production of novel ideas.     

Burn-out im Spannungsfeld von Persönlichkeit und Organisationsstruktur

Burnout is a significant threat to physical and mental health and is the result of individual vulnerability and an organizational culture with high performance expectations, chronic work overload and blurred borders between work and leisure. The phases of burnout will first be defined and the various types of risk factors for burnout as well as the corresponding interactions will be differentiated. In addition to the individual risk factors this article will present in particular the organization-linked risk factors. The general risk factors which occur with rapidly changing rates and high flexibility demands in many modern working environments will first be discussed. From these, particular organization-linked risk factors will be distinguished which are dependent on the respective type of organization. The interaction of particular types of organization with different personality styles results in different forms of burnout. When such an interaction is known individuals who are susceptible to organization-linked burnout can be recognized more easily and the organizational culture can be influenced. Finally, reflections on the prevention and treatment of burnout at the individual and organizational level will be presented.     

Implicit and explicit components of dual adaptation to visuomotor rotations

Concurrent adaptation to two different visuomotor transformations has been shown to be possible as long as discriminative contextual cues are available. The authors examined explicit and implicit components of visually cued dual adaptation in younger and older adults. They found that only young adults, but not old adults, produced appropriate adaptive shifts of hand-movement direction to compensate for the visuomotor rotations. Aftereffects, conceived as a measure of implicit knowledge, were only poorly developed. Furthermore, only participants in the younger group exhibited systematic explicit knowledge of the visuomotor rotations. Subsequent analyses revealed strong correlations between the quality of explicit knowledge and the overall visuomotor adaptation. Thus, visually cued dual adaptation to two opposite visuomotor rotations is primarily mediated by conscious strategic corrections based on explicit knowledge of the transformations, a process, which is selectively impaired in older adults.     

The effects of mechanical transparency on adjustment to a complex visuomotor transformation at early and late working age

Mechanical tools are transparent in the sense that their input-output relations can be derived from their perceptible characteristics. Modern technology creates more and more tools that lack mechanical transparency, such as in the control of the position of a cursor by means of a computer mouse or some other input device. We inquired whether an enhancement of transparency by means of presenting the shaft of a virtual sliding lever, which governed the transformation of hand position into cursor position, supports performance of aimed cursor movement and the acquisition of an internal model of the transformation in both younger and older adults. Enhanced transparency resulted in an improvement of visual closed-loop control in terms of movement time and curvature of cursor paths. The movement-time improvement was more pronounced at older working age than at younger working age, so that the enhancement of transparency can serve as a means to mitigate age-related declines in performance. Benefits for the acquisition of an internal model of the transformation and of explicit knowledge were absent. Thus, open-loop control in this task did not profit from enhanced mechanical transparency. These findings strongly suggest that environmental support of transparency of the effects of input devices on controlled systems might be a powerful tool to support older users. Enhanced transparency may also improve simulator-based training by increasing motivation, even if training benefits do not transfer to situations without enhanced transparency.
