Overt and covert verbal problem-solving strategies: developmental trends in use, awareness, and relations with task...

Age-related changes in children's use, self report, and awareness of verbal problem-solving strategies (private speech) and strategy effectiveness were explored with a large (N = 2,156) cross-sectional sample of children aged 5 to 17. Children's verbal strategies moved from overt, to partially covert, to fully covert forms with age. Self-reports of verbal strategy use were accurate yet incomplete. Awareness of children's use of verbal strategies was low and increased with age. Although verbal strategies were associated with competence among the youngest children, self-talk was unrelated to task performance for older children, suggesting considerable persistence over time of a relatively ineffective strategy. Awareness was not a prerequisite for children's verbal strategy use but was positively associated with strategy effectiveness among those who talked.
