In early adolescence, levels of conscientiousness and agreeableness have been found to temporarily decrease, with levels of neuroticism increasing, indicating a dip in personality maturation. It is unknown whether these changes are related to the process of puberty, a major developmental milestone with numerous changes for children. Here, we first…

The current investigation tested predictions from the interactionist model (IM) of socioeconomic influences on the development of negative personality traits with respect to feelings of alienation and low well-being. The model tested proposed that lower family socioeconomic status would lead to fewer parenting and material investments in the next…

The reactivity-regulation model suggests that the origins and maintenance of shyness results from relatively high levels of reactivity in combination with relatively low levels of regulation. Although this model has received some empirical support, there are still issues regarding directionality of the relations among variables and a dearth of…

The present cross-sectional study investigated age and gender differences in motivational manifestations of the Big Five in a large German-speaking Internet sample (N = 19,022). Participants ranging in age from 16 to 60 years completed the Five Individual Reaction Norms Inventory (FIRNI; Denissen & Penke, 2008a), and two traditional Big Five…

The authors investigated normative beliefs about personality development. Young, middle-aged, and older adults indicated the age-relevance of 835 French adjectives by specifying person characteristics as typical for any age decade from 0 to 99 years. With this paradigm, the authors determined age-relevance (How typical is a characteristic for a…

Examined the developmental courses of temperamental constructs using structural equation model fitting with children from 3 to 48 months of age. Found that across all measurement occasions, models that fit best were those that allowed for stability in temperament to be at least partially mediated through intermediate forms of the trait. (JPB)

Examined the number and nature of temperamental types in 488 children, age 3 years 6 months. Configural-frequency-analysis methods showed clear support for two temperament types: controlled-nonexpressive and noncontrolled-expressive. These types showed meaningful differences against external criteria related to a wide range of problem behaviors.…

Examined psychological maturity based on personal strivings in 108 adults ages 17 to 82 years. Results supported hypotheses that older people would list more strivings concerning generativity and ego integrity and fewer strivings concerning identity and intimacy, and that maturity and age would be positively associated with subjective well-being.…

Data for this study of 108 young adults from the New York Longitudinal Study include measures of temperament derived from two sources: interviews conducted with subjects' mothers when the children were 3 and 4 years of age and measures of Type A behavior derived from interviews with the subjects during young adulthood. (Author/NH)

Explores the influence of three aspects of other-oriented consequences upon ongoing delay behavior of kindergarten children: (a) knowing that one's behavior has consequences for others, (b) having social relationships with affected others, (c) having potential future social consequences for the individual. A number of personality measures were…

A partial sequential design was used to study personality development over a 10-year-period. Data on the Inventory of Psychosocial Development were collected from: a sample of college students in 1966; the same sample as alumni in 1976; and a sample of undergraduates in 1976. (JMB)

Explored genetic and environmental underpinnings of temperamental differences in 3- to 16-month-old twins and their parents. Found that additive genetic and shared environmental effects best represented smiling, laughter, and duration of orienting. Shared environmental effects fully accounted for co-twin similarity for soothability. Additive…

Assessed temperament of newborn twins using comprehensive neonatal exam that focused on irritability, resistance to soothing activity, and reinforcement value. Some infants were later assessed at 9 months. Emotional activity appeared to be core dimension stretching over ages and is discussed in relation to formulations of infant temperament.…

Two studies examined children's inferences of personality for actors engaging in different domains of behavior. In both studies, first, fourth, and seventh graders were given two descriptions of actors engaging in either moral or conventional transgressions. Findings indicated that children's concepts of persons were inferred from information…

Examines main and interactional effects of paternal identification on a son's personality and drug use. As in another study by Brook et al., included in this issue, questionnaires were completed by White college students and their fathers. Sons who identified with fathers having positive traits were more likely to possess these traits themselves.…
