The purpose of this study was to explore Vygotsky's notion of private speech as a cognitive self-regulatory process and how it related to creativity measures among at-risk children. Thirty-two Head Start and state-funded Pre-K children completed the Torrance creativity test Thinking Creatively in Action and Movement (TCAM). The children's private speech was collected in an open play context and while children completed structured logical--mathematical activities. Results revealed that both originality and fluency creativity were related to self-direction private speech and grand total private speech. Findings support that cognitive self-regulating private speech may be related to creative thinking and that private speech may offer a method for assessing early creative thinking in children from various cultural and economic backgrounds.
