The Role of Parent–Child Interaction in Early Language Development: A Review of the Literature

Parent-child interaction plays a crucial role in shaping children’s language development, particularly during early childhood. The quality and quantity of interactions influence language acquisition, vocabulary growth, and communication skills. Responsive parenting, characterized by warmth, sensitivity, and engagement, fosters a supportive environment for language learning. This review examines the literature on parent-child interaction and its impact on early language development, highlighting the significance of interactional patterns, parental input, and socio-economic factors. This review focuses on the role of parent-child interaction in early language development. Findings from our study revealed that parent-child interaction significantly impacts early language development. Studies indicate that responsive parenting, including verbal responsiveness and joint attention, predicts better language outcomes. Parents’ use of child-directed speech, expansions, and recasts facilitates language learning. Children from socio-economically disadvantaged backgrounds often experience less verbal interaction, contributing to language delays. However, interventions targeting parent-child interaction have improved language skills in at-risk children. The quality of interaction, rather than quantity, is a stronger predictor of language development. Fathers’ and mothers’ interaction styles contribute uniquely to children’s language growth, highlighting the importance of involving both parents. Parent-child interaction is a critical factor in early language development. Responsive, engaging, and supportive interactions foster language learning, while socio-economic disparities can hinder it. Targeted interventions and parental education can promote language skills in at-risk children. Encouraging positive parent-child interaction benefits children’s language development and long-term academic success.
