Playing a cooperative game promotes preschoolers’ sharing with third-parties, but not social inclusion.

This study examined the effect of gaming context on young children’s prosocial behaviors. Dyads of 4- to 5-year-old children (N = 96) played the same game cooperatively, competitively, or solitarily. After playing the game for a total of ten minutes, sharing with and social inclusion of uninvolved third-parties as well as free play with previous co-players was observed. Children shared less with third-parties after playing the game competitively than after playing it cooperatively. Playing a solitary game resulted in intermediate levels of sharing. The structure of the game did not differentially impact measures of social inclusion or free play. [ABSTRACT FROM AUTHOR]
