The Social Nature of Private Speech of Preschoolers During Problem Solving
Extending Vygotsky's theory, young children's private speech during problem solving is conceptualised as having a dual nature; as a reaction to the task and as, at the same time, an indirect appeal to a potentially helpful person. The interactional function of private speech is elaborated within a developmental pragmatic frame of explanation. Based on the dual nature conceptualisation of private speech, the hypothesis was tested that children would produce more private speech during problem solving following interaction with a collaborative adult than following interaction with a non-collaborative adult, the adult being non-actively present during the child's execution of the cognitive task. Twenty-two children (ages: 4 years 2 months to 4 years 10 months) participated in the experiment. Support was found for the main hypothesis. No reliable relationship was found between the amount of private speech produced and the quality of task performance. Results are discussed in relation to other studies of private speech, two of which are re-interpreted in accordance with a dual nature conceptualisation of private speech. The role of private speech in the regulation of non-verbal task performance is critically analysed. It is emphasised that private speech should be studied while taking into account the interactional framework in which the child has been functioning.
