Baggally attempts to explain a game of a seventeen-month-old girl in terms of the hedonics of play. The game consisted merely in standing upright on the couch and then slowly swaying and overbalancing so as to fall over and sit down with a bump after which the child scrambled up and the game was repeated. During the repetitions, the time taken in swaying before the fall became more and more lengthened until ultimately she lost interest in the game and turned her attention to other activities.
