This study compared perceptions of relationships with parents, best friends, siblings, and imaginary companions among 4-year-olds with invisible friends, object companions, or no imaginary companion. Findings indicated that parents afforded instrumental help, and siblings were associated with conflict. Real and imaginary friendship provisions were similar. Imaginary friends were preferred as objects of nurturance. Findings imply that 4-year-olds have differentiated relationship schemas, with those of children with imaginary friends particularly distinct. (Author/KB)
