This paper compared two conceptions of time transformations - one related to theories of development, based on the notions of convergency and closure; and the other related to the theories of Bergson, Deleuze and Guattari, which are based on the ideas of divergency and differentiation. Analysing the theories of cognitive development we call attention to the concept of chronological time, the regimen of structure filiation, and the overcoming of the child’s form of knowledge by that of the adult. Guided by the Bergson’s idea of coexistence of times, Deleuze and Guattari’s concept of child-becoming, which states the inventive tendency that remains in the form of virtuality in every cognitive formation - in adults and children - and that characterizes contemporary cognition are discussed.
