A foundational mechanism underlying human cooperation is reciprocity. In the context of repeated interactions with others, it is not always clear the degree to which in-kind responses reflect responsiveness to partners' prior behaviors ("reactive" responses), an interest unrelated to the partner ("nonreactive" responses), or…

Research Findings: Social constructivist theories have proposed that caregivers' perceptions of children as morally responsible agents are an important factor in children's moral development. However, there is substantial variance in caregivers' ascriptions of moral agency to young children. The present study examined caregiver social conformity…

Research Findings: Prosocial behavior in early childhood can be assessed by various informants and methodologies, but the information each provides may differ in meaningful ways. The present study measured and compared young children's (N = 486; age: M = 48.51 months, SD = 8.22) prosocial behavior based on parent reports, teacher reports, and…

How does teacher-child interaction quality in early child care and education settings influence the development of social-emotional skills in children at around two to three years of age? We measured the quality of interactions on the side of the child care teachers (N = 9, CLASS Toddler) and assessed self-regulatory skills through an individual…

Valid information on early social-emotional competence is essential to diagnose, treat, and prevent behavioral problems in children and adolescents. Particularly in young children, social-emotional competence is frequently measured using parent and teacher ratings that frequently exhibit low agreement. Therefore, the present study on n = 532…

From a young age, children in Western, industrialized societies overimitate others' actions. However, the underlying motivation and cultural specificity of this behavior have remained unclear. Here, 3- to 8-year-old children (N = 125) from two rural Namibian populations (Haillom and Ovambo) and one urban German population were tested in two…

In all human cultures, people gesture iconically. However, the evolutionary basis of iconic gestures is unknown. In this study, chimpanzees and bonobos, and 2- and 3-year-old children, learned how to operate two apparatuses to get rewards. Then, at test, only a human adult had access to the apparatuses, and participants could instruct her about…

Research Findings: Behavioral self-regulation is crucial for school success. Although behavioral self-regulation typically grows rapidly during the preschool period, children in this age group vary widely in their behavioral self-regulation capacities. The present study investigated 3 potential determinants of growth rates in behavioral…

The aim of this randomized controlled study is to explore the long-term efficacy of the widely used Triple P parent group training as a universal prevention intervention. 280 families with children between 3 and 6 years participated (N=186 Triple P, N=94 control group}. A multi-method assessment was conducted pre, post and one to four years after…
