Third-party punishment has been regarded as an important mechanism to promote fairness. Although previous research has shown that children aged 6 and older punish unfair behaviors at a personal cost, it is unknown whether they actually intend to establish equality or whether equality is a mere byproduct of punishment. In this preregistered study,…

Parents are considered a major resource in children's numeracy development. The relative role of cognitive and motivational parenting practices, however, is unclear given that the two types of practices have largely been studied in isolation. The current study simultaneously estimated the contributions of several cognitive and motivational…

Children's beliefs about the contribution of effort and ability to success and failure shape their decisions to persist or give up on challenging tasks, with consequences for their academic success. But how do children learn about the concept of "challenge"? Prior work has shown that parents' verbal responses to success and failure shape…

Past research has demonstrated that both consequentialist motives (such as deterrence) and deontological motives (such as "just deserts") underlie children's and adults' punitive behavior. But what motives do we ascribe to others who pursue punishment? The present work explores this question by assessing which punitive motives children…

One long-standing theoretical model of shyness proposes that the origins and maintenance of shyness are associated with an approach-avoidance motivational conflict (Asendorpf, 1990), such that shy individuals are motivated to socially engage (high approach motivation) but are too anxious to do so (high avoidance motivation). However, this model…

This longitudinal study (three waves across a school year) investigated the links between children's motivations to respond without prejudice and their ethnic outgroup attitudes at the between-person level (means and changes over time) and the within-person level (time-specific fluctuations). Participants were 945 ethnic majority students…

Developmental theory historically viewed demanding roles (at home, job) as important developmental contexts. However, adolescents' participation in these roles has fallen. This qualitative research examined role experiences in United States youth development programs. A central question among others was, "How can youth experience internal…

Virtually nothing is known about the role that tone of voice may play in motivating interactions. Herein, we use an experimental approach to explore for the first time how the same directive instructions ("Do well at the play") have different effects on adolescents depending on the motivational tone of voice used to convey these…

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…

Across three studies, we examined 4- to 7-year-olds' predictions of goal-directed behaviors when goals conflict with preferences. In Study 1, when presented with stories in which a character had to act against basic preferences to achieve an interpersonal goal (e.g., playing with a partner), 6- and 7-year-olds were more likely than 4- and…

Much is known about young children's helping behavior, but little is known about the underlying motivations and emotions involved. In 2 studies we found that 2-year-old children showed positive emotions of similar magnitude--as measured by changes in their postural elevation using depth sensor imaging technology--after they achieved a goal for…

To benefit from the exploration of their bodies and their physical and social environments, infants need to detect sensorimotor contingencies linking their actions to sensory feedback. This ability, which seems to be present in babies from birth and even in utero, has been widely used by researchers in their study of early development. However, a…

Moral identity research to date has largely failed to provide evidence for developmental trends in moral identity, presumably because of restrictions in the age range of studies and the use of moral identity measures that are insensitive to age-related change. The present study investigated moral identity motivation across a broad age range (14-65…

In a previous study, parent-child praise was observed in natural interactions at home when children were 1, 2, and 3 years of age. Children who received a relatively high proportion of process praise (e.g., praise for effort and strategies) showed stronger incremental motivational frameworks, including a belief that intelligence can be developed…

Social approach and social avoidance goals (i.e., approach of positive and avoidance of negative outcomes in social situations) are important predictors of the feeling of being socially integrated or isolated. However, little is known about the development of these goals across adulthood. In a large diary study with N = 744 young (18-39 years),…
