Jeremy Sawyer recounts that, after Lev S. Vygotsky's death, Jean Piaget conceded the Russian psychologist correctly understood the social origins, functions, and developmental trajectory of children's egocentric speech (now called private speech) but dismissed this work as irrelevant to children's egocentrism or nondifferentiation of perspectives. Sawyer asserts that, although Piaget precluded perspective taking in egocentric speech, a post-Vygotskian framework suggests private speech and sociodramatic play may actually promote perspective taking, thereby reducing egocentrism. In light of these assertions, Sawyer examines private speech transcripts from preschoolers for evidence of perspective taking and concludes that they suggest children internalize perspectival differences through private speech and use more implicit perspective taking than explicit mental-state terms. And preschoolers, the author suggests, employ more sociodramatic speech in a sociodramatic play context to enact imaginary scenarios and pretend roles. He concludes that, rather than a remnant of egocentrism, private speech may be a psychologicaltool for engaging multiple perspectives.
