Kind actions, kind reactions? The impact of considerate behavior on children’s social preferences
Being considerate of other people's needs is an important way in which people show they care about others. Do young children pick up on this social signal? Across three preregistered studies ( N = 254; 125 boys, 129 girls, 87%-89% Dutch), we investigated children's evaluation of and behavior toward considerate and inconsiderate peers. An internal meta-analysis of Studies 1 and 2 showed that children (4-7 years) did not like considerate peers more…
Here, Let Me Do It for You”: Psychological Consequences of Receiving Direct and Indirect Help in Childhood
What are the psychological consequences of receiving direct and indirect help in childhood? We conducted three preregistered experiments (N = 619, 7–9 years, 80% Dutch, 51% girls, 49% boys, mostly higher socioeconomic status) in the Netherlands (July 2020–July 2022). Children received direct help (correct answer), indirect help (hint), or no help. An internal meta-analysis showed that children who received help felt less competent, liked the task…
Prosocial choices: How do young children evaluate considerate and inconsiderate behavior
Adults often act considerately toward others, for example, by leaving the last cookie on a plate or stepping aside on a busy sidewalk. What do young children infer from observing considerate behavior? In three preregistered studies, we assess how young children evaluate considerate and inconsiderate behavior by showing them animated videos in which targets make decisions that either leave or limit choice options for others. Study 1 ( N = 372 6- t…
When Helping Hurts: Children Think Groups That Receive Help Are Less Smart
Helping has many positive consequences for both helpers and recipients. However, in the present research, we considered a possible downside to receiving help: that it signals a deficiency. We investigated whether young children make inferences about intelligence from observing some groups of people receive help and other groups not. In a novel group paradigm, we show that children (4–6 years) think groups that receive help are less smart (n = 44)…
Children tell more prosocial lies in favor of in-group than out-group peers
Children tell prosocial lies from the age of three years onward, but little is known about for whom they are inclined to lie. This preregistered study examined children's (N = 138, 9-12 years) prosocial lying behavior toward minimal in-group and out-group peers. Additionally, children evaluated vignettes in which an in-group peer told a prosocial lie to an in-group or out-group peer. Results show that only older children told more prosocial lies …
Children’s helping behavior in an ethnic intergroup context: Evidence for outgroup helping
Two studies examined when and why children (10-13 years) help ethnic in-group and out-group peers. In Study 1 (n = 163) children could help an out-group or in-group peer with a word-guessing game by entering codes into a computer. While children evaluated the out-group more negatively than the in-group, they helped out-group peers more than in-group peers. Study 2 (n = 117) conceptually replicated the findings of Study 1. Additionally the results…
First Arrival and Collective Land Ownership: How Children Reason About Who Owns the Land
Four survey experiments provide evidence that children (9–12 years) infer collective land ownership from first arrival. In Experiments 1 and 2, children indicated that a group owns an island relatively more than another group when having been or living on the island first. In the third experiment, it was found that first comers were considered to own the land more independently of whether the second group joined or succeeded them in living on the…
Ethnic Helping and Group Identity: A Study among Majority Group Children
Two vignette studies were conducted on children's evaluations of ethnic helping. In the first study, 272 native D utch children (mean age = 10.7) evaluated a child who refused to help in an intra‐group context ( D utch– D utch or T urkish– T urkish) or inter‐group context ( D utch– T urkish or T urkish– D utch). Children evaluated not helping in intra‐group situations more negatively than not helping in inter‐group situations. This suggests that …
Majority Children's Evaluation of Acculturation Preferences of Immigrant and Emigrant Peers
Using an experimental design, native majority group children (8-13 years, N = 842) evaluated acculturation strategies (assimilation, integration, and separation) adopted by immigrant and emigrant peers. There were medium to large effects of the perceived acculturation strategies on children's peer evaluations. Overall, assimilation was valued most, followed by integration and separation. These effects were in part mediated by perceived national b…
