There is a growing literature on children’s environmental choices and how they may affect self-regulatory processes such as emotion regulation. However, since the physical features of a specific playground area are generally confounded with its social features (such as social density and characteristics of the child who plays there), it is not clear whether children choose to play in a particular location as a function of its physical or social aspects. The present study was designed to examine whether children’s choices of where to play were affected when the same physical features were associated with different social features. If the physical features of a playground are primarily responsible for children’s choices, their responses should be the same regardless of whether the social features are changed. However, if social features of an area are most important for children’s choices of where to play, their responses should differ when the social features are different. A total of 21 girls and 10 boys in third grade, 7 girls and 12 boys in fourth grade, and 28 girls and 42 boys in fifth grade were shown two models each of two school playgrounds that contained different configurations of grass, asphalt, trees, and play structures. Neither of the playgrounds resembled their own school playground. The two models of each school playground had different patterns of social density represented by means of small figures of boys and girls placed on the models: one represented a typical social density pattern with most of the figures located in public central areas of the playground (such as open grassy areas and on the play structure), while the other concentrated the figures in private peripheral areas (near the fences at the edge of the playground and at the edges of the school). For each of the four models, children were asked to indicate where they would choose to play when experiencing each of six different emotional states. Choices of where to play were categorized as public areas or private areas. The results indicated that children chose public areas more often for positive emotion states and private areas more often for negative emotional states. However, they did not choose different locations on either of the playgrounds as a function of the different social density. These results suggest that children are more influenced by the physical aspects of a particular location than by the social aspects when making a choice about where to play.
