There is extensive research on the development of cheating in early childhood but research on how to reduce it is rare. The present preregistered study examined whether telling young children about a story character's emotional reactions towards cheating could significantly reduce their tendency to cheat (N = 400; 199 boys; Age: 3 to 6 years). Resu...

Cheating is a common human behavior but few studies have examined its emergence during early childhood. In three preregistered studies, a challenging math test was administered to 5- to 6-year-old children (total N = 500; 255 girls). An answer key was present as children completed the test, but they were instructed to not peek at it. In Study 1, ma...

Research on moral socialization has largely focused on the role of direct communication and has almost completely ignored a potentially rich source of social influence: evaluative comments that children overhear. We examined for the first time whether overheard comments can shape children's moral behavior. Three- and 5-year-old children (N = 200) p...

Although there has been extensive research on how children distribute resources with respect to quantity, little is known about how these decisions are affected by resource quality. The current research addressed this question by conducting two preregistered studies in which 3-, 5-, and 7-year-old children (total N = 360) made anonymous distributio...

The current research examined whether young children engage in unethical behavior to a greater extent when they have a prosocial justification for doing so. Participants (3- and 5-year-olds, N = 240) played a guessing game in which they were tempted to cheat to win a prize after promising not to do so. In Study 1, children were randomly assigned to...
