Maternal behaviors in toddlerhood as predictors of children's private speech in preschool.

Private speech is an important strategy reflecting children's self-regulation, and thus understanding how parenting may support private speech can inform intervention work on improving self-regulation. The current study longitudinally investigated how sensitive parenting and directive parenting in toddlerhood interacted to predict preschoolers' private speech in an emotion-eliciting task. In toddlerhood, maternal parenting behaviors were observed during two freeplay sessions. Preschoolers' social and private speech were transcribed and coded during a frustration task. Whereas parenting did not relate to other forms of private speech, preschoolers' facilitative task-relevant private speech was predicted by the interaction of mothers' sensitive and directive behaviors. When sensitivity was high, parents who were less directive had children who used more facilitative task-relevant private speech. These findings highlight that children's regulation may be supported through the combination of high sensitivity and low directiveness when parents and children are engaged in unstructured play together.
