“…The phenomenon has a long history in the psychological literature. Whereas some early studies associated the phenomenon with negative attributes (e.g., Svendsen, 1934;Ames & Learned, 1946;Nagera, 1969), subsequent, more controlled studies have identified many positive attributes that are correlated with having an imaginary companion throughout the lifespan.Children with imaginary companions have a high predisposition to fantasy-based play (Taylor, 1999) and, in general, have been shown on several measures to be highly creative (e.g., Singer, 1961;Schaefer, 1969;Hoff, 2005, but see Pearson, Rouse, Doswell, Ainsworth, Dawson, Simms, et al, 2001. With respect to socio-cognitive development, Taylor and Carlson (1997) showed that 4-year-old children with imaginary companions passed theory-of-mind tasks before same-age peers without imaginary companions.…”
