Origins of verbal logic: spontaneous denials by two- and three-year olds*

  • Roy D. Pea (a1)
Abstract

Children two to three years of age can spontaneously correct false statements and affirm true ones in a modified sentence verification paradigm. Such performances imply that very young children display knowledge of the rules of correspondence between language and reality (truth conditions) which are central to propositional logic, at an age when logical development in cognition has not been previously acknowledged.
