Matching methods such as nearest neighbor propensity score matching are increasingly popular techniques for controlling confounding in nonexperimental studies. However, simple k:1 matching methods, which select k well-matched comparison individuals for each treated individual, are sometimes criticized for being overly restrictive and discarding…

We used three identity processes (i.e., commitment, in-depth exploration, and reconsideration of commitment) from a recently developed model of identity formation to derive empirically identity statuses in a sample of 1952 early and middle adolescents. By means of cluster analysis, we identified five statuses: achievement, foreclosure, moratorium,…

Positive connections to other human beings are the foundation of healthy development.

Two experiments examined developmental patterns in children's conditional reasoning with everyday causal conditionals. In Experiment 1, a group of pre-, early, young, and late adolescents generated counterexamples for a set of conditionals to validate developmental claims about the counterexample retrieval capacity. In Experiment 2, participants…

It has been argued that peers are the most important agent of adolescent socialization and, more specifically, that this socialization process occurs at the child-specific (or nonshared environmental) level (J. R. Harris, 1998; R. Plomin & Asbury, 2005). The authors sought to empirically evaluate this nonshared environmental peer influence…
