This article focuses on the development of forms of vitality play, a recentlydescribed type of play, and links it to the development of symbolic play, one of the most studied types of play in developmental psychology. Two adult?infant dyads were videotaped longitudinally duringin-house free play meetings every 15 days during the third year of life.Convergence technique was applied in order to accelerate the longitudinalstudy. A total of 17 hours 48 minutes were registered in 28 sessions. An observationalcode with categories of forms of vitality play (a non-figurativeplay frame in which child and adult playtogether with the dynamics of their own movements and sounds in arepetition-variation form), symbolic play, and categories of combinedpatterns of both types of play was applied. The rate of each play wascalculated for different age periods. Formsof vitality play is present at a constant rate during the third year of life. Symbolicplay flourishes during this period. Combined play patterns are not the mostfrequent but are present from the beginning to the end of the third year. We suggest thatFoVP favors intimate and intersubjective experiences essential to theunderstanding and the development of the interpersonal world; that it can bethought of as a good runway for the development of symbolic play; and that itprepares the child to participate in the temporal arts that belong to hisculture.
