Parenting and Temperament as Interacting Agents in Early Language Development

Objective. This study investigated relations among parenting, temperament, and early language, especially parenting as a moderator of the temperament-language association. Design. Measures of temperament, parenting (maternal responsiveness), and language were obtained from a sample of 102 predominantly European American, middle-class mother - infant dyads who were studied when the infants were 12 and 16 months of age. Results. The interaction between infant distress to novelty and maternal responsiveness at 12 months was related to 16-month language, such that when infants were low in distress to novelty, more responsive parenting was associated with better language abilities. Moreover, for boys only, greater maternal responsiveness was related to better language abilities only when boys displayed less smiling and laughter. Conclusions. The effects of emotionality and parenting on language acquisition depend on the level of the other.
