During their third year of life, toddlers become increasingly skillful at coordinating their actions with peer partners and they form joint commitments in collaborative situations. However, little effort has been made to explain interindividual differences in collaboration among toddlers. Therefore, we examined the relative influence of distinct in...

The main aim of this study was to explain the domain-specificity of early prosocial behavior in different domains (i.e., helping, comforting, and cooperation) by simultaneously assessing specific socio-cognitive factors (i.e., self-other-differentiation and joint attentional skills) that were hypothesized to be differentially related to the three d...

We concur with the authors of the two target articles that Open Science practices can help combat the ongoing reproducibility and replicability crisis in psychological science and should hence be acknowledged as responsible research practices in hiring and promotion decisions. However, we emphasize that another crisis is equally threatening the cre...

Helping is usually perceived as a positive behavior, but it can also have negative side effects. Moreover, helping decisions are often embedded in complex social situations that can create social dilemmas for children and adults, such as the decision whether or not to help a friend steal. However, based on previous research, it remains unclear how...

Previous studies based on non-WEIRD (Western, Educated, Industrialized, Rich, and Democratic) samples provide initial evidence that the still-face effect is universal. Based on the assumption that – independent of their cultural niches – infants share some fundamental expectations of social interactions, we put forth the assumption that a universal...

The coronavirus pandemic poses a substantial threat to people across the globe. In the first half of 2020, governments limited the spread of virus by imposing diverse regulations. These regulations had a particular impact on families as parents had to manage their occupational situation and childcare in parallel. Here, we examine a variation in par...

This lab‐based longitudinal study examines whether parental structuring (i.e., encouragement, modeling, and praise) has effects on helping behavior across developmental time, across recipients or both. Based on behavioral data assessed at 12, 15, 18, 21, and 24 months (N = 38 dyads), the main findings are that, first, when analyzing the effects of...

From a developmental systems perspective, this chapter focuses on the question whether culture matters for children's early social-cognitive development. Based on a review of the current cross-cultural literature, we evaluate the current state of research on cross-cultural similarities and differences in major developmental milestones of early soci...

Human perception differs profoundly between individuals from different cultures. In the present study, we investigated the development of context-sensitive attention (the relative focus on context elements of a visual scene) in a large sample (N = 297) of 5- to 15-year-olds and young adults from rural and urban Brazil, namely from agricultural vill...

Previous research has shown that young children robustly display in‐group favoritism; that is, they favor in‐group over out‐group members. Moreover, preschoolers also consider information on morality in their evaluations of others. In the present study, we integrated both aspects: In particular, fifty‐six 4‐ to 6‐year‐old preschoolers were assigned...

In two experiments, the imitation of helping behavior in 16‐month‐olds was investigated. In Study 1 (N = 31), infants either observed an adult model helping or not helping another individual before they had the opportunity to assist an unfamiliar experimenter. In one of two tasks, more children helped in the prosocial model condition than in the no...

This study analyzes temperamental and social correlates of 18-month-olds’ (N = 58) instrumental helping (i.e., handing over out-of-reach objects) and comforting (i.e., alleviating experimenter’s distress). While out-of-reach helping as a basic type of prosocial behavior was not associated with any of the social and temperamental variables, comforti...

According to previous research, social experiences with other children might explain why three-year-olds are already quite proficient in understanding desires but not beliefs as subjective mental states. This study investigated toddlers’ (N = 50) developing subjective understanding of incompatible desires around the age of 3 years (M = 35.5 months)...

Anthropological studies and recent evidence from cross-cultural psychology suggest considerable variations in the way prosocial behavior is conceptualized and embedded in social interactions across cultures. Important questions are which aspects of different ecosocial contexts might explain these variations and how these aspects influence prosocial...

Adolescents tend to adopt behaviors that are similar to those of their friends, and also tend to become friends with peers that have similar interests and behaviors. This tendency towards homogeneity applies not only to conventional behaviors such as working for school and participating in sports activities, but also to risk behaviors such as drug...
