The authors examined the development of self-esteem across the life span. Data came from a German longitudinal study with 3 assessments across 4 years of a sample of 2,509 individuals ages 14 to 89 years. The self-esteem measure used showed strong measurement invariance across assessments and birth cohorts. Latent growth curve analyses indicated…

In this article, we contrast evolutionary and psychobiological models of individual development to address the idea that individual development occurring in prototypically risky and unsupportive environments can be understood as adaptation. We question traditional evolutionary explanations of individual development, calling on the principle of…

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…

Data from the National Education Longitudinal Study of 1988 are used to estimate the effect of type of disability (in order of frequency, learning, other, emotional, hearing, visual, physical and speech impairment) on young people's progress toward four adult transitions: fending full-time employment, establishing an independent residence,…

Two cohorts of alumni, leading-edge and trailing-edge baby boomers, first tested in their college years, were followed to ages 43 (N = 136) and 54 (N = 182) on a measure of Erikson's theory of psychosocial development. Hierarchical linear modeling was used to model the trajectory of growth for each psychosocial issue across middle adulthood. As…

The developmental course of 9 temperament dimensions were documented in 104 children from ages 2 through 12. Overall, with the advancement of age, children's temperament showed less developmental change as indexed by mean ratings on the temperament dimensions and greater cross-time stability as assessed by the rank ordering of children across…

The present study used meta-analytic techniques (number of samples = 92) to determine the patterns of mean-level change in personality traits across the life course. Results showed that people increase in measures of social dominance (a facet of extraversion), conscientiousness, and emotional stability, especially in young adulthood (age 20 to…

This article reports the first year results of a pilot study of 21 developmental milestones achieved by 82 visually impaired children in New York City. Some delays in visual-motor activities were found, as well as differences in the sequence of acquiring skills. Children with additional handicaps acquired milestones at a slower rate. (Author/DB)

A longitudinal study examined relations between 2 approaches to identity development: the identity status model and the narrative life story model. Turning point narratives were collected from emerging adults at age 23 years. Identity statuses were collected at several points across adolescence and emerging adulthood, as were measures of…

Conducted a three-year longitudinal analysis of morphological spelling strategies in second through fourth graders. Found that, when children first adopt morphologically determined spelling patterns, they disregard the morphological basis. Generalization progresses from grammatically inappropriate words to the right grammatical category to the…

Examined evidence for transitions in first and second graders' analogical reasoning, over a six-month period. Found strong evidence for bimodality in test performance frequency distributions and weaker evidence for inaccessibility in frequency distributions. Transitional subjects showed a temporary increase of inconsistent solution behavior and…

Data from 6 sites in 3 countries were examined to determine developmental course of physical aggression in childhood and to analyze linkages to violent and nonviolent offending outcomes in adolescence. Findings indicated that among boys, chronic physical aggression during elementary school years increased risk for continued physical violence and…

Discusses a longitudinal study of children's evolving concept of "word." Concludes that tacit awareness of word in spoken and written language precedes explicit awareness. Finds that children in different developmental stages perform differently on reading tasks. Suggests that development of the concept of word relates to experience with writing…

Examined the development of seven infants with "missing milestones" in motor development. Found that three children had normal development, three developed global developmental delay, and one was diagnosed with multiple cavernous haemangiomata in the brain. Suggested that missing milestones can be a benign variation of normal motor…

To extend research linking pubertal timing and adolescent health outcomes, this study examines boys' pubertal timing and subsequent interpersonal success and health behaviors in mid adulthood. Past research has shown that boys' pubertal timing is associated with both positive and negative developmental outcomes in the short term, and so it is…
