Recent studies have concluded that children's development of private speech (private speech internalization) is related to and important for developing mathematical ability. In this article, we review a project consisting of studies exploring the cognitive factors that may underlie differences between the use of private speech by children with…

The majority of recent studies conclude that children's private speech development (private speech internalisation) is important for mathematical development and subject to disabling. The main concern of the present study was whether or not the two phonological memory factors evaluated in the study (i.e. the results of children's digit span…

The majority of recent studies conclude that children's private speech development (private speech internalization) is related to and important for mathematical development and disabilities. It is far from clear, however, whether private speech internalization itself plays any causal role in the development of mathematical competence. The main…

The overall purpose of the present study was to examine whether an intervention program (50 weeks), modeled as training in accordance with the developmental course of private speech (from audible private speech to silent inner speech), itself would add positively to the development of mathematical competence. The sample comprised two comparable…

The present study examines private speech and strategy-use patterns for solving simple number fact problems in addition. The progressive differentiation by grade between children's levels of private speech internalization--including silence--was investigated and related to children's developmental patterns for subcategories of strategy-use…
