“…At the structural level, studies have demonstrated that characteristics of elaborative talk, namely, embellished open-ended questions and regular positive feedback during past-event talk, are positively related to the development of children’s language as well as literacy skills. Importantly, this relation has been revealed across different cultural contexts and milieus (e.g., Reese, 1995; Reese, Leyva, Sparks, & Grolnick, 2010; Sparks, Carmiol, & Ríos, 2013; Sparks & Reese, 2013; Wang, 2007) and is also supported by intervention studies (see Reese, Sparks, & Leyva, 2010, for a review). This result is in line with studies that have explored conversational interactions in general, demonstrating that adults’ diversity of speech is significant for children’s language development (e.g., vocabulary size, phonological awareness, grammatical skills; see Snow, 2014; Tamis-LeMonda, Luo, & Song, 2014, for reviews).…”
