In this article, we introduce a systemic framework for the development of learning potential to professional excellence inspired by the Actiotope model of giftedness. First, we critically reflect on three theoretical approaches representing different psychological constructions of learning potential. We label these approaches theories of…

Molenaar's (2015) article concerns Developmental Systems Theory (DST) in relation to behavior genetics and he presents implications of DST for empirical research, especially the need for subject-specific studies. In this commentary, the article is discussed from a broader developmental science perspective, particularly regarded through the lens of…

In this article, we directly question the common practice in growth mixture model (GMM) applications that exclusively rely on the fitting model without covariates for GMM class enumeration. We provide theoretical and simulation evidence to demonstrate that exclusion of covariates from GMM class enumeration could be problematic in many cases. Based…

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…

This article presents an overview of quantitative methodologies for the study of stage-sequential development based on extensions of Markov chain modeling. Four methods are presented that exemplify the flexibility of this approach: the manifest Markov model, the latent Markov model, latent transition analysis, and the mixture latent Markov model.…

Longitudinal studies have shown how early developmental contexts contribute significantly to self-development; their influence extends through adulthood, informs sociality, and affects resilience under severe stress. While the importance of sociality in trauma recovery is recognized, the relationship between developmental and posttrauma contexts…

By combining a positivistic and an interpretive approach, this research investigates the learning opportunities that contemporary industrial work processes and workplaces offer for employees individually and collectively. The research explores how employees can become trained through their work and how individual development may expand to…

Challenges the typical treatment of causal effects in longitudinal data, arguing that models should be conceptualized and tested in ways that directly reflect prior assumptions as to the trait- or state-like nature of the variables. Examples demonstrate that meaningful longitudinal studies of state variables can be conducted without assuming their…

Schroots reviews historical models of age, aging, and the aged and suggests that differences in the aging process can be explained by a branching theory based on gerodynamics. Charness's comment suggests ways to improve gerodynamics as a form of inquiry about human development and aging. (SK)

The philosophies underlying the learning and structural theories used in psychology are described in this article. It is argued that a dialectical view provides some ways to breach the chasm between learning theory and the study of human development. (Author/DB)

Following the assumptions of ecological socialization research, adequate analysis of socialization conditions must take into account the multilevel and multivariate structure of social factors that impact on human development. This statement implies that complex models of family configurations or of socialization factors are needed to explain the…

Determines patterns of differential human development in a longitudinal study of 417 male and 358 female college students ages 18 to 30. Findings suggest individuality in development is associated with significant qualitative individual differences that are best described on a cross-time basis. (BJD)

Argues that a better understanding of developmental processes is provided by three types of operant research -- laboratory behavioral descriptions, descriptions of naturalistic behavior-environment interdependencies, and predictive naturalistic studies. The usefulness of these processes are examined in light of the goals of life span developmental…

Over 600 White females between 10.5 and 18.5 years of age were studied to test construct comparability across adolescence. Assessed were emotional functioning, eating problems, self-reflection, self-image, and mastery/adjustment to examine meaning equivalence in self-concepts and developmental psychopathology. Results suggest that the five factors…

Stability and predictive validity in the language and play development of 41 toddlers were studied. Links between language and symbolic play of toddlers were examined at 13 and 20 months in terms of homotypic, heterotypic, or mediated models of association. In the homotypic model, performance on a variable is related to performance on the same…
