This study examined whether children understand that people selectively conceal or express emotion depending upon the context. We prepared two contexts for a verbal display task for 70 first-graders, 80 third-graders, 64 fifth-graders, and 71 adults. In both contexts, protagonists had negative feelings because of the behavior of the other…

This current study examined human children's and adults' automatic processing of proportion using a Stroop-like paradigm. Preschool children and university students compared the areas of two sectors that varied not only in absolute areas but also in the proportions they occupied in their original rounds. A congruity effect was found in…

The increasingly prolonged transition to adulthood has raised concerns about the nature and timing of growth in the attainment of important psychosocial competencies in young people. Changes over time in self-reported competencies (work orientation, identity, intimacy) were examined in 198 Canadians, who were followed for the first 4 years of…

Previous research on sensation seeking (SS) was dominated by a variable-oriented approach indicating that SS level has a linear relation with a host of problem behaviors. Our aim was to provide a person-oriented methodology--a probabilistic clustering--that enables examination of both inter- and intra-individual differences in not only the level,…

Drawing on data from a three-wave longitudinal study, the present research examined predictors of young adults' intentions to participate in politics and their actual political activities while referring to the broader assumptions of the theory of planned behavior. The analyses were based on a sample of university students from the federal…

This study proposes a developmental model of financial capability to understand the process by which young adults acquire the financial knowledge and behaviors needed to manage full-time adult social roles and responsibilities. The model integrates financial knowledge, financial self-beliefs, financial behavior, and well-being into a single…

In this paper we present domain-specific measures of academic and social self-regulation in young adults. We base our scales on Baltes and colleagues' Selection, Optimization, and Compensation (SOC) model, and establish the factor structure of our new measures using data collected from a sample of 152 college students. We then compare the…

The predictive relations between social capital depth (high-quality relationships across contexts) and breadth (friendship network extensivity) and early-adult life adjustment outcomes were examined using data from a prospective longitudinal study. Interviews at age 22 yielded (a) psychometrically sound indexes of relationship quality with…

Null hypothesis testing (NHT) is the most commonly used tool in empirical psychological research even though it has several known limitations. It is argued that since the hypotheses evaluated with NHT do not reflect the research-question or theory of the researchers, conclusions from NHT must be formulated with great modesty, that is, they cannot…

On the basis of self-determination theory it is proposed that adolescents' motives for forming and maintaining identity-relevant commitments can be either autonomous or controlled in nature. This study examined whether motives for identity commitments would add to the prediction of late adolescents' adjustment beyond the effect of strength of…

This study presents a new approach to estimation of a nonlinear growth curve component with fixed and random effects in multilevel modeling. This approach can be used to estimate change in longitudinal data, such as day-of-the-week fluctuation. The motivation of the new approach is to avoid spurious estimates in a random coefficient regression…

In Experiment 1, Japanese children (4-, 5-, 7-, and 10-year-olds (n = 78)) and adults (n = 36), answered questions about the possibility of psychogenic bodily reactions, i.e., bodily outcomes with origins in the mind. The 4- and 5-year-old preschoolers typically denied that bodily conditions could originate in mental states. Developmentally,…

We examined support and conflict with parents and close friends in a sample of ethnically diverse young adults (European-, Asian-, Cuban-, Latin-, and Mexican Americans). College students (N = 495) completed six subscales from the Network of Relationships Inventory (NRI; Furman & Buhrmester, 1985). Friends were rated higher than parents on global…

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…

Recent years have seen an impressive increase in web-based research, of which we review and discuss two main types. First, researchers can create online versions of traditional questionnaires. Using the internet in this way usually does not compromise the psychometric properties of such measures, and participants are typically not less…
