The Sooner, the Better: Early Reading to Children

The Sooner, the Better: Early Reading to Children As reading to children plays an important role in language development, primary caregivers are often encouraged to read to their children from a very young age. However, little is known about the age at which such reading should start. The linguistic skills of 104 children were assessed shortly before school entry. Their parents were asked how old their children were when they first read to them and how often they had read to their children. Almost half of the study children were read to before they were 6 months old. The age at which children were first read to was closely associated with family characteristics such as socioeconomic status, the frequency with which children were read to as preschoolers, and with children’s linguistic and cognitive competencies. The findings imply that reading books to very young children indeed contributes meaningfully to a favorable home literacy environment and supports children’s language development. Keywords storybook reading, onset of reading to a child, home literacy environment (HLE), parent–child interactions, linguistic competencies parent–child interactions (Farrant & Zubrick, 2012; Niklas, Introduction 2015; Niklas, Möllers, & Schneider, 2013). Children’s language and literacy competence does not begin Other theoretical frameworks relevant to a discussion of when children enter school—Children’s literacy learning the influence of the HLE include Vygotsky’s (1978) social starts well before formal schooling, and studies have shown constructivist theory and Bourdieu’s (1986) social theory. that children are sensitive to speech even prenatally (e.g., According to Vygotsky, children learn through observation Moon, Lagercrantz, & Kuhl, 2013; Partanen et al., 2013). and interaction with knowledgeable others in social contexts. Parents and primary caregivers (subsequently referred to as In the context of language and literacy learning, the impor- parents) are highly influential in a child’s early learning as tance of parents modeling literacy activities and supporting parent–child interactions are frequent and ongoing. Indeed, their children’s emerging literacy skills is clear. Bourdieu research shows that the home literacy environment (HLE) is theorized that the cultural capital to which an individual or a the context in which children first acquire the language and family has access is a key component of the HLE. This cul- literacy skills that equip them to make sense of, describe, and tural capital includes cultural objects and resources such as participate in the world (e.g., Liebeskind, Piotrowski, books and works of art, as well as the ability to utilize and Lapierre, & Linebarger, 2014; Niklas & Schneider, 2013; learn from such objects and resources.

Abstract

As reading to children plays an important role in language development, primary caregivers are often encouraged to read to their children from a very young age. However, little is known about the age at which such reading should start. The linguistic skills of 104 children were assessed shortly before school entry. Their parents were asked how old their children were when they first read to them and how often they had read to their children. Almost half of the study children were read to before they were 6 months old. The age at which children were first read to was closely associated with family characteristics such as socioeconomic status, the frequency with which children were read to as preschoolers, and with children’s linguistic and cognitive competencies. The findings imply that reading books to very young children indeed contributes meaningfully to a favorable home literacy environment and supports children’s language development. Keywords storybook reading, onset of reading to a child, home literacy environment (HLE), parent–child interactions, linguistic competencies parent–child interactions (Farrant & Zubrick, 2012; Niklas, Introduction 2015; Niklas, Möllers, & Schneider, 2013). Children’s language and literacy competence does not begin Other theoretical frameworks relevant to a discussion of when children enter school—Children’s literacy learning the influence of the HLE include Vygotsky’s (1978) social starts well before formal schooling, and studies have shown constructivist theory and Bourdieu’s (1986) social theory. that children are sensitive to speech even prenatally (e.g., According to Vygotsky, children learn through observation Moon, Lagercrantz, & Kuhl, 2013; Partanen et al., 2013). and interaction with knowledgeable others in social contexts. Parents and primary caregivers (subsequently referred to as In the context of language and literacy learning, the impor- parents) are highly influential in a child’s early learning as tance of parents modeling literacy activities and supporting parent–child interactions are frequent and ongoing. Indeed, their children’s emerging literacy skills is clear. Bourdieu research shows that the home literacy environment (HLE) is theorized that the cultural capital to which an individual or a the context in which children first acquire the language and family has access is a key component of the HLE. This cul- literacy skills that equip them to make sense of, describe, and tural capital includes cultural objects and resources such as participate in the world (e.g., Liebeskind, Piotrowski, books and works of art, as well as the ability to utilize and Lapierre, & Linebarger, 2014; Niklas & Schneider, 2013; learn from such objects and resources.
