Direct and correlated responses to bi-directional selection on pre-adult development time in Drosophila montana.

2019

Selection experiments offer an efficient way to study the evolvability of traits that play an important role in insects’ reproduction and/or survival and to trace correlations and trade-offs between them. We have exercised bi-directional selection on Drosophila montana flies’ pre-adult development time under constant light and temperature conditions for 10 generations and traced the indirect effects of this selection on females’ diapause induction under different day lengths, as well as on the body weight and cold tolerance of both sexes. Overall, selection was successful towards slow, but not towards fast development. However, all fast selection line replicates showed at the end of selecti…

Raising Children with Poor School Performance: Parenting Styles and Short- and Long-Term Consequences for Adolescent and Adult Development.

2019

This study examines the correlates of authoritative (warmth and strictness), indulgent (warmth but not strictness), authoritarian (strictness but not warmth), and neglectful (neither warmth nor strictness) parenting with short- and long-term socialization outcomes in adolescents and adults, with and without poor school performance during adolescence. Short- and long-term socialization outcomes were captured by multidimensional self-esteem (academic/professional, emotional, and family), psychological maturity (self-competence, social competence, and empathy), and emotional maladjustment (nervousness, emotional instability, and hostility). Participants (1195 female and 874 male) consisted of …

Does successful attainment of developmental tasks lead to happiness and success in later developmental tasks? A test of Havighurst's (1948) theses.

2006

This study tested Havighurst's (1948) contention that successful attainment of age-specific developmental tasks leads to happiness and success in achieving subsequent tasks. A longitudinal study on 146 participants was carried out to investigate the links between developmental progression in adolescence and young adulthood and happiness, which was assessed by two indices: high self-esteem and low symptomatology. The importance individuals place on achieving normative developmental tasks and current developmental status was assessed six times during adolescence and young adulthood, self-esteem and symptomatology were assessed five times. Results revealed a shift in the time frames for accomp…

The Jyväskylä Longitudinal Study of Personality and Social Development (JYLS)

2006

The Jyvaskyla Longitudinal Study of Personality and Social Development is an ongoing long-term study that began in 1968. From the very beginning, data have been collected within a framework of emotional and behavioral regulation. This chapter presents the framework model and its theoretical rationales. Data collection waves are described, first, from childhood to adolescence, and second, in adulthood. Results on continuity in socioemotional behavior and its developmental background, problem behavior and health, and positive development are presented so as not to overlap with results in the other chapters of this book. INTRODUCTION The title of the Jyvaskyla Longitudinal Study of Personality…

We may state that the path of development of an organism can play an important role in its immediate realization and also in its possible transformation. This leads to the problem of the existence of a causative link between individual development (ontogeny) and evolutionary history (phylogeny). This problem which has been dealt with by numerous authors, has led to contradictory answers, depending on the direction of the supposed connection: from the evolutionary history to individual development or vice versa, that is, from individual development to the evolutionary history.

From causal thinking to wisdom and spirituality: some perspectives on a growing research field in adult (cognitive) development

2015

This article concentrates on the latest international trends in the research on psychological development of adults, and especially on the development of cognition. The field of research has been very fragmented, and researchers have kept creating new models one after another to describe their own lines of thought and also seeking for empirical evidence for their models. This has created a rather equivocal picture of the phenomenon itself. The present article attempts to identify the historical roots of the field, and introduces descriptive factors that could conceptually determine the gist of the phenomenon. In this context we will discuss, mainly, research going back to Piaget and Perry, …

Identity Development in Adulthood: A Longitudinal Study

2000

Abstract Identity status interviews involving five domains of life (religious beliefs, political ideology, occupational career, intimate relationships, and lifestyle) were conducted with 249 women and men at ages 27 and 36. The results on overall identity and domain-specific identities confirmed our general hypothesis as to the strengthening of the commitment process: (1) stability was higher in the identity statuses involving commitment (identity achievement and foreclosure) than in the statuses not involving commitment (identity diffusion and moratorium); (2) an increase in the salience of identity domains could be attributed to an increase in the commitment process; (3) transitions into …

Identity Formation in Adulthood: A Longitudinal Study from Age 27 to 50.

2016

Longitudinal patterns of identity formation were analyzed in a representative cohort group of Finnish men and women born in 1959 across ages 27, 36, 42, and 50. The data were drawn from the Jyväskylä Longitudinal Study of Personality. Identity status (diffused, moratorium, foreclosed, achieved) from all four ages was available for 172 participants (54% females). Marcia’s Identity Status Interview used in this research included five domains: religious beliefs, political identity, occupational career, intimate relationships, and lifestyle. The findings indicated great variability in identity status across domains at each age level, and the identity trajectories fluctuated from age 27 to 50. T…

Company matters: Goal-related social capital in the transition to working life

2005

Abstract Using longitudinal data on 343 young adults, the present study investigated the social ties involved in young adults’ work-related goals, how these ties change during transition to working life, and whether social ties contribute to success in dealing with the transition. The results showed that goal-relevant social ties reflected changes in the young adults’ developmental context. Furthermore, social ties that included a person with high socioeconomic status and weaker social ties contributed to employment success, whereas social ties containing one’s supervisor were associated with quality of employment. The results also showed that goal-related social hindrance increased young a…

Processes of Personality Development in Adulthood: The TESSERA Framework.

2016

The current article presents a theoretical framework of the short- and long-term processes underlying personality development throughout adulthood. The newly developed TESSERA framework posits that long-term personality development occurs due to repeated short-term, situational processes. These short-term processes can be generalized as recursive sequence of Triggering situations, Expectancy, States/State expressions, and Reactions (TESSERA). Reflective and associative processes on TESSERA sequences can lead to personality development (i.e., continuity and lasting changes in explicit and implicit personality characteristics and behavioral patterns). We illustrate how the TESSERA framework f…
