Multiple facets of well-being are known to show steep end-of-life deteriorations. However, the underlying mechanisms and pathways are vague. Capitalizing on an earlier review of the existing empirical literature on terminal decline, we present a conceptual/methodological framework that can be used as a tool to structure future inquiry aimed at…

Researchers are often interested in studying how the timing of a specific event affects concurrent and future development. When faced with such research questions there are multiple statistical models to consider and those models are the focus of this paper as well as their theoretical underpinnings and assumptions regarding the nature of the…

Growth mixture modeling (GMM) is a method for identifying multiple unobserved sub-populations, describing longitudinal change within each unobserved sub-population, and examining differences in change among unobserved sub-populations. We provide a practical primer that may be useful for researchers beginning to incorporate GMM analysis into their…

Planning for the future and developing a personalized identity are conceived of as important developmental tasks that adolescents and emerging adults are confronted with on the pathway to adulthood. The present study set out to examine whether both tasks develop in tandem by using a short-term longitudinal dataset consisting of 371 college…

Growth curve modeling has become a mainstay in the study of development. In this article we review some of the flexibility provided by this technique for describing and testing hypotheses about: (1) intraindividual change across multiple occasions of measurement, and (2) interindividual differences in intraindividual change. Through empirical…

Investigated development of altruism in children according to a theoretical perspective that integrated Piagetian micromodels accounting for change from preoperational to operational stages. Subjects were 90 children of 5-12 years of age. Older children were more likely to consider an altruistic act in terms of gain construction than cost…

Describes a model of adaptation to the environment across the life span. Proposes that an individual's performance in an activity is affected not only by cognitive capacity but also by perceptions and definitions of the activity. Empirical support for the model, based on a survey of individuals' everyday experiences and on laboratory studies, is…

It is well known that human development is influenced by social change. In particular, as evidenced by research on German unification, the rapid change of social institutions can impact on various aspects of behaviour and development. Based on my own research experience in this field, I want to show the necessity for a better interdisciplinary…

Studied the impact of life experience on women's cognitive and ethical development. Considered the structure and historical and social factors of such development, and the importance of higher education in attaining high positions on W.G. Perry's developmental scale. Factors found to affect women's positions on the scale were attitudes toward…
