This randomized controlled trial explored the effects of parental reminiscing training on preschoolers' memory and metacognition among French-speaking White parents and their typically developing children (24 females, 20 males; M[subscript months] = 49.64) in Belgium. Participants were assigned, with age stratification, to the immediate…

The moral self-concept (MSC) is an early indicator of how children view themselves as moral agents. It has been proposed that an important feature of an established self-concept (SC) is sufficient coherency in how one views oneself. Furthermore, the MSC is expected to develop into a multidimensional, hierarchical construct which is stable over…

Collaboration is an early emerging component of successful cooperative relations that produces a cascade of positive social preferences between collaborators. Concurrently, robust preferences for affiliated others may restrict these benefits to in-group peers. We investigated how in-group affiliation (based on minimal group markers) and…

Infants can help and share in the second year of life. However, there is limited knowledge as to variability in these behaviors as a function of target (e.g., caregiver vs. unfamiliar adult) and the influence of caregiver support on infant prosocial behavior. Infants (N = 268, 124 female) at 1-2 years of age (M = 1.47, SD = 0.27) and again at 2-3…

Previous research has found that even young children accurately assign wealth labels (e.g., rich or poor) to real-world wealth symbols, such as pictures of houses. However, it is unclear whether children spontaneously consider individuals' wealth status when predicting how they will behave toward others. In Study 1, children (n = 100, ages 4-5 and…

Three experiments showed that gratitude positively affected preschool children's prosocial behavior. In the studies, the experimenter induced gratitude by giving a token gift and then making a request for help or to share resources. Experiment 1 (N = 126, 4- to 6-year-olds) showed that gratitude increased helping behaviors toward the benefactor,…

Joint engagement--the sharing of events during social interactions--is an important context for early learning. To date, sharing topics that are only heard has not been systematically documented. To describe the development of auditory joint engagement, 48 child-parent dyads were observed 5 times from 12 to 30 months during seminaturalistic play.…

Secrets carry valuable social information. Because the content of secrets can be damaging to the secret-keeper's reputation, people should only disclose their secrets to people whom they trust. Therefore, tracking which people know each other's secrets can be used as cue of social relationships: If one person tells another person a secret, those…

The association between children's social-status within their peer-group and their prosociality was examined among fourth and sixth graders (N = 276), using sociometric nominations, and actual sharing with a fellow in-group member, or a member of an out-group. Results show an overall increase in sharing with age, and an overall correlation between…

Reputational concerns are known to promote cooperation. Individuals regularly act more prosocially when their behavior is observable by others. Here, we investigate 4- and 5-year-old (N = 144) children's reputational strategies in a competitive group setting. The aim of the current study was to explore whether children's sharing behavior is…

We examined the development of sharing behavior of children (aged 6 to 12) within the unique, minority population of Christian Arab children in Israel (N = 319). Children had the opportunity to share candy with a needy or non-needy recipient. Parents' level of religiosity was assessed using the Duke University Religion Index questionnaire (DUREL).…

Young children share fairly and expect others to do the same. Yet little is known about the underlying cognitive mechanisms that support fairness. We investigated whether children's numerical competencies are linked with their sharing behavior. Preschoolers (aged 2.5-5.5) participated in third-party resource allocation tasks in which they split a…

Expectations that others will reciprocate to the benefits they received from us play a crucial role for the establishment of stable reciprocal exchange within social relationships. In the current study, 3- to 5-year-old preschool children allocated in a first phase more resources to one recipient than to another recipient. Subsequently, they had…

We examined the role of the recipient's neediness as a moderator in the relation between children's household religiosity and prosocial behavior. Examining the behavior of children (2nd and 5th graders) from religious and nonreligious households in the dictator game, we found that the extent of sharing did not differ significantly between the 2…

Given the centrality of prosociality in everyday social functioning, understanding the factors and mechanisms underlying the origins of prosocial development is of critical importance. This experiment investigated whether experience with reciprocal object exchanges can drive the developmental onset of sharing behavior. Seven-month-old infants took…
