Previous literature has suggested the existence of a close relationship between individuals' intellectual abilities and their cognitive profile, understood as their performance in tasks tapping into the different cognitive domains. This relationship has typically been discussed in populations characterized as having high intellectual abilities, as…

Differentiation of intelligence refers to changes in the structure of intelligence that depend on individuals' level of general cognitive ability (ability differentiation hypothesis) or age (developmental differentiation hypothesis). The present article aimed to investigate ability differentiation, developmental differentiation, and their…

Throughout childhood and adolescence, humans experience marked changes in cortical structure and cognitive ability. Cortical thickness and surface area, in particular, have been associated with cognitive ability. Here we ask the question: What are the time-related associations between cognitive changes and cortical structure maturation.…

Many researchers have used the standard Iowa Gambling Task (IGT) to assess decision-making in adolescence given increased risk-taking during this developmental period. Most studies are cross-sectional and do not observe behavioral trajectories over time, limiting interpretation. This longitudinal study investigated healthy adolescents' and young…

The stability of callous-unemotional (CU) traits and both individual and contextual factors that influence this stability have been studied in community adolescent samples but not to great extent in adolescents who have been arrested. We estimated the developmental changes in CU traits measured over the course of 36 months (6-month intervals)…

Anthony's theory of the development of extraversion in children requires that there should be a negative correlation between extraversion and intelligence after age 13 or 14. To test this Raven's Progressive Matrices and the Junior Eysenck Personality Inventory were administered to 801 adolescents. Findings did not support Anthony's theory.…

New research reveals that media use may contribute to shaping not only adolescents' developing beliefs about gender, race, sexuality, and beauty ideals but also their brains and biology.

Adolescents' developing sense of competence is based on two domains, ability and intelligence. Intelligence testing generally presumes a conception of ability as current capacity that limits the extent to which effort can improve performance. Conceptions of intelligence, and other skills, involve implications about the nature of different forms of…

Investigated relationships among prenatal maternal resources, perceptions about parenting, and children's temperament at 6 months, and adaptation of 90 adolescent mothers three years after the birth of their first child. Found that maternal resources uniquely predicted later maternal cognitive functioning, personal adjustment, and child abuse…

This monograph details the Notre Dame Parenting Project, a comprehensive longitudinal study of the lives of adolescent mothers and their children from pregnancy through the first 8 years of life, describing how their respective developmental trajectories are interwoven and linked to the social contexts in which they live. A total of 281…
