Humans experience emotional benefits from engaging in prosocial behavior. The current work investigates factors that influence the experience of happiness from giving to others in early childhood. In three studies with 5-year-olds (N = 144), we find that young children are happier from giving resources to others than from receiving resources for themselves (Study 1) and investigate when children are most happy from giving. In Study 2, children were happier when they could see the beneficiary's positive reaction, suggesting that empathizing with the beneficiary's positive emotion contributes to happiness (consistent with the concept of vicarious-joy). In Study 3, children were happier after they gave resources than when they watched someone else give resources, indicating that being responsible for prosocial action contributes to children's happiness (consistent with the concept of warm-glow). These results provide a critical step toward understanding when children experience happiness from giving and a foundation for investigating happiness as a mechanism supporting early prosociality. 相似文献

High levels of prenatal alcohol exposure (PAE) result in significant cognitive deficits in children, but the exact nature of the dose-response relationship is less well understood. To investigate this relationship, data were assembled from six longitudinal birth cohort studies examining the effects of PAE on cognitive outcomes from early school age through adolescence. Structural equation models (SEMs) are a natural approach to consider, because of the way they conceptualise multiple observed outcomes as relating to an underlying latent variable of interest, which can then be modelled as a function of exposure and other predictors of interest. However, conventional SEMs could not be fitted in this context because slightly different outcome measures were used in the six studies. In this paper we propose a multi-group Bayesian SEM that maps the unobserved cognition variable to a broad range of observed outcomes. The relation between these variables and PAE is then examined while controlling for potential confounders via propensity score adjustment. By examining different possible dose-response functions, the proposed framework is used to investigate whether there is a threshold PAE level that results in minimal cognitive deficit. 相似文献
