Children will increasingly come of age with personified robots and potentially form social and even moral relationships with them. What will such relationships look like? To address this question, 90 children (9-, 12-, and 15-year-olds) initially interacted with a humanoid robot, Robovie, in 15-min sessions. Each session ended when an experimenter…

In the current study, based on a sample of 1,873 adolescents between 11.4 and 20.9 years of age from the first 3 waves of the National Longitudinal Study of Adolescent Health, we investigated the longitudinal effects of future orientation on levels of and developmental changes in problem behaviors, while controlling for the effects by impulsivity;…

Contemporary perspectives on age differences in risk taking, informed by advances in developmental neuroscience, have emphasized the need to examine the ways in which emotional and cognitive factors interact to influence decision making. In the present study, a diverse sample of 901 individuals between the ages of 10 and 30 were administered a…

A cross-sectional, stratified random sample of 1,891 male and female adolescents (age range from 12 years 6 months to 17 years 6 months) was tested in 1970 with the Grades 9-12 form of the Primary Mental Abilities test. (Editor)

Analyzing problem-behavior trajectories can be difficult. The data are generally categorical and often quite skewed, violating distributional assumptions of standard normal-theory statistical models. In this article, the authors present several currently available modeling options, all of which make appropriate distributional assumptions for the…

The connotative structure of self-concept was examined by factor analysis of a semantic differential instrument and found to be essentially constant through adolescence, more so for boys than for girls. (Author)

The effects of punishment on resistance-to-deviation behavior in adolescents were assessed in a laboratory analogue designed to stimulate a naturalistic situation. Contrary to prediction, mothers appeared to be more influential punitive agents than fathers. (Author/CB)

This longitudinal study with 62 children and adolescents examined the validity of the consolidation/transition model in the context of moral reasoning development. Results of standard statistical and Bayesian techniques supported the hypotheses regarding cyclical patterns of change and predictors of stage transition, and demonstrated the utility…

Study suggests that the effects of father absence on daughters appear during adolescence and are manifested mainly as an inability to interact appropriately with males, rather than in other deviations from appropriate sex typing or in interactions with females. (Author/CB)

Study reaffirmed the central significance of the peer group's influence on adolescent behavior. (Authors)

A developmental model of paranoid behavior is proposed which includes among its postulates the expectation that sons who have maintained an open style of adaptation to aversive maternal control will be less tolerant of ambiguity than will sons who have adopted a closed style. (Author)

Fifth- and eleventh-grade males and females who knew each other ( knowers'') judged classmates' photographs on physical attractiveness, perceived attitude similarity, and interpersonal attraction. Nonknowers'' (male and female classmates in different schools in the same grades) judged the same photographs on physical attractiveness. (Editor)

The nature of adolescent trait change appears less dictated by are-related components than by the type of social change patterns which are setting the environmental milieu for adolescents of all ages over a given period of time. (Authors)

Future time perspective is defined as the forward expanse of time over which future images of the self are projected. (Author/MB)

Used a dynamic systems (DS) approach to study changes in structure of family interactions in problem-solving sessions during the early adolescent transition of boys in 149 families. Constructed state space grids (a new DS method) for families across five waves of videotaped data collection before, during, and after the transition. Found that DS…
