Vygotsky suggested that play is the main source of development in early years. "In play a child deals with things as having meaning. Word meanings replace objects, and thus an emancipation of word from object occurs" (Vygotsky, 1933, p. 11). However, there is a transfer of meanings as a child in imaginary play can think of a stick as a horse as he or she mentally designates the object or property as the word. "Play is the source of development and creates the zone of proximal development. Action in the imaginative sphere, in an imaginary situation, the creation of voluntary intentions and the formation of real life plans and volitional motives - all appear in play and make it the highest level of preschool development" (Vygotsky, 1933, p. 16).
