This longitudinal case study from a Complex Dynamic Systems Theory (CDST) perspective touches upon an under-researched issue: L1 development over the lifespan. Levinson (1978) predicts three stages in adulthood: early, mid and late, with a decline in late adulthood. We examine Diane Larsen-Freeman's publications over a period of 50 years (from age…

Previous research documented positive associations between cognitively stimulating work and levels of cognitive performance, while longitudinal associations are less clear. We used 20-year longitudinal data from the Interdisciplinary Longitudinal Study of Adult Development and Aging (ILSE) to examine the role of perceived work environment…

Attachment anxiety is a form of attachment insecurity characterized by chronic worries about rejection and need for reassurance. Given the critical role a sense of security plays in maintaining healthy relationships, individuals high in attachment anxiety tend to struggle in romantic relationships, which carries serious implications for their…

In this longitudinal Canadian study, we investigated the relationship between the developmental trajectories of community involvement and generative concern measured at ages 23, 26, and 32. Participants completed a questionnaire on youth involvement, the Youth Involvement Inventory (YII), and the Loyola Generativity Scale (LGS) at all 3 ages. A…

Work hard in school, graduate from a top college, establish a high-paying professional career, enjoy the long-lasting reward of happiness. This is the American Dream--and yet basic questions at the heart of this competitive journey remain unanswered. Does competitive success, even rarified entry into the Ivy League and the top one percent of…

Research in developmental psychology has traditionally focused on parents' roles as agents of emotion socialization in their children's socioemotional development. By contrast, little longitudinal research has examined sociocultural mechanisms shaping parents' own emotional development. Immigrant parents are an ideal population in which to examine…

Views on aging have been shown to predict the occurrence of events related to physical health in previous studies. Extending these findings, we investigated the relation between aging-related future self-views and life events in a longitudinal study across a range of different life domains. Participants (N = 593, age range 30-80 years at…

In Western cultures, life narratives are typically expected to recount the narrator's life from birth to the present. Disparate autobiographical memories need to be integrated into a more or less coherent story, which is facilitated by an overarching temporal macrostructure. The temporal macrostructure consists of elaborated beginnings that…

Erikson's (1950) model of adult psychosocial development outlines the significance of successful involvement within one's relationships, work, and community for healthy aging. He theorized that the consequences of not meeting developmental challenges included stagnation and emotional despair. Drawing on this model, the present study uses…

Happiness is an important indicator of well-being, and little is known about how it changes in the early adult years. We examined trajectories of happiness from early adulthood to midlife in 2 Canadian longitudinal samples: high school seniors followed from ages 18-43 and university seniors followed from ages 23-37. Happiness increased into the…

Prior research has demonstrated both socialization and selection effects for the relationship between antisocial peer affiliation and externalizing problems in adolescence. Less research has evaluated such effects postadolescence. In this study, a cross-lagged panel analysis was used to evaluate the extent of "socialization" (i.e., the…

The present study addresses older adults' developmental regulation when faced with progressive and irreversible vision loss. We used the motivational theory of life span development as a conceptual framework and examined changes in older adults' striving for control over everyday goal achievement, and their association with affective well-being,…

Employing a life span developmental systems perspective, this study used a 5-wave (1985-1992) Canadian longitudinal data set (N = 404) to examine trajectories of intrinsic and extrinsic work values and job entitlement beliefs from age 18 to 25. Piecewise growth models (Slope 1: age 18-20; Slope 2: age 20-25) showed intriguing patterns of change.…

This study examined longitudinal changes in coping and defense mechanisms in an age- and gender-stratified sample of 392 European American adults. Nonlinear age-related changes were found for the coping mechanisms of sublimation and suppression and the defense mechanisms of intellectualization, doubt, displacement, and regression. The change…

Youth must navigate various developmental tasks as they transition to adulthood, and during this period of "emerging adulthood," young people explore roles and relationships before committing to the ones they will fill as adults. This brief seeks to identify patterns and transitions during emerging adulthood to obtain a better…
