A Review of Imaginary Companions and Their Implications for Development

A curious childhood phenomenon that has received relatively little attention in developmental literature is the imaginary companion (IC). Increased recognition of the importance of imaginative play and a desire to stimulate children’s early cognitive development makes ICs a particularly relevant topic. The significant prevalence of ICs in the population has permitted a modest yet diverse range of research investigating the functions, correlates, and implications of ICs for the children that create them. This literature review summarizes some of this research in order to describe the functions and forms that ICs may take, as well as social and personality characteristics of children with ICs. It also examines the role that ICs may serve in cognitive and social development, particularly with respect to children’s acquisition of Theory of Mind. Finally, this article addresses ways to integrate ICs into other aspects of children’s lives, gaps in the existing literature, and potential directions for future research in the field.
