Characteristics of play are "flexibility, nonliterality, positive affect, intrinsically motivated" (Krasnor & Pepler, 1980).
Add to the above list a preoccupation with means to a goal rather than the end in itself and remove intrinsic motivation (Smith, Takhvar, Gore, & Vollstedt, 1985).
Some play activities are marked by inflexibility, involuntary actions, and portrayal of negative affect, which negates the above list of characteristics (Sutton-Smith & Kelly-Byrne, 1984).
Play is intrinsically motivated, concerned with means rather than ends, is child-directed, nonliteral, free from externally dictated rule structures, rules that do exist can be modified by players, and requires active engagement of players (Rubin, Fein, & Vandenberg, 1983).
"An activity with or without materials in which bodily movement is an end in itself (Buhler, 1935)."

"Optimal generic learning by experimentation in a relaxed field (Fagan, 1976, pp. 99)."
