One of the more well-known and explored types of play is "pretend play" (also known as symbolic play or fantasy play), in which children distort reality to behave in a nonliteral, "as if" way (Fein, 1981). The inclusion of toys and dolls, which enhance children's pretend play, is a prevalent feature of their play (Singer and Singer, 1990). Pretend play was initially thought to emerge around the age of two and then wane between the ages of four and seven (Piaget, 1962).
