The Power of Language Nutrition for Children's Brain Development, Health, and Future Academic Achievement

      Highlights

      • Describe the role of pediatric providers in literacy and promotion of Language Nutrition.
      • Understand the influence of Language Nutrition on a child's future education and health outcomes.
      • Develop skills to teach parents why and how to engage in language-rich interactions and to provide Language Nutrition to their children.

      Abstract

      Language Nutrition, a term created to describe language exposure that is rich in quality and quantity and delivered in the context of social interactions, is crucial for a child's development and is strongly associated with his/her future literacy, academic achievement, and health. However, significant differences in children's early language environments contribute to disparities in their educational and health trajectories. Interventions, including book distribution programs, coaching parents to enrich their child's language environment, and public awareness campaigns, have all been shown to positively influence a child's access to language-rich interactions. Incorporating Language Nutrition coaching and literacy promotion into pediatrics is a promising platform for building the capacity of parents to provide language exposure to their children. By teaching parents both how and why to treat their child as a conversational partner and by modeling such interactions, pediatric health care providers can help parents set their children on a pathway toward literacy, educational success, and health.

      Early childhood is a critical period for developing language skills, including learning to understand and speak language (
      ). Language enables a child to communicate and interact with others, which encourages both social and cognitive development and is a prerequisite of school readiness and literacy (

      ).

      Language Nutrition

      Early exposure to language-rich interactions between adults and children forms the basis of Language Nutrition, a term created to describe the use of language sufficiently rich in engagement, quality, quantity, and context that it nourishes the child neurologically, socially, and linguistically (

      ). A conversational turn is defined as back-and-forth communication, or adult speech followed by a child's vocalization within 5 seconds or vice versa. Conversational turns invite children into the conversation regardless of whether they are able to communicate verbally or through nonverbal signals and provide children with the opportunity to build their communication skills in the context of an engaged social relationship (

      ). This research suggests that the words a child hears need to be directed at the child for them to have developmental benefits. As a result, language-rich interactions with an engaged caregiver provide children with an environment that is conducive to language learning.
      There are a number of programs across the United States that have begun to incorporate Language Nutrition as a concept into pediatric health care. Language Nutrition coaching can be executed in different programs, by different pediatric providers, and in a variety of settings with the same goal of improving rich parent/adult–child interaction.

      ). As a result, low-income children arrive in kindergarten with exposure to only about one third of the words heard by their more affluent peers. This disparity in language exposure contributes to gaps in vocabulary, school readiness, and long-term academic achievement. It is important to note, however, that socioeconomic status does not by itself create these disparities, but rather differences in average language exposure between socioeconomic groups.

      Purpose

      Although all families communicate and interact with their babies, there is substantial variation in children's early language environments.
      The importance of talking to babies, reading to young children, and using everyday words as opportunities to enhance early language learning has been gaining national prominence. Although all families communicate and interact with their babies, there is substantial variation in children's early language environments. Parent knowledge of child development and the importance of language exposure greatly affects the quality of a child's language environment and opportunities for learning (
      • Rowe M.L.
      Child-directed speech: Relation to socioeconomic status, knowledge of child development and child vocabulary skill.
      ). Parents of infants and young children are uniquely poised to be their child's first and best teachers given the time they spend with their child and the influence of parenting on a child's health and development. Therefore, parents are key targets for education and skill building around language.
      The purpose of this article is to review key components of language-rich interactions and examine existing or previously developed interventions that focus on improving the language and literacy skills of 0- to 3-year-old children. This two-fold purpose will lead to a discussion of how pediatric health care providers can integrate Language Nutrition coaching into their daily practice to help support families in optimizing their child's future health and educational trajectory.

      Review of the Literature

      PubMed and Web of Science were searched for peer-reviewed studies published between 1990 and 2015 in the English language using the key terms parent or caregiver, infant or child, intervention, talk or read, and language or literacy. Studies were selected if they discussed or evaluated parent-based interventions for improving the language or literacy of 0- to 3-year-children. A total of 57 articles met search criteria.

      The Basis of Language Nutrition

      Quantity of Words

      Many studies have documented the effects of the quantity of child-directed speech on a child's cognitive, language, and academic outcomes (

      ). Greater quantity of speech directed at a young child may result in improved language and academic outcomes by providing children with more opportunities to interpret language and be exposed to a greater variety of grammatical combinations and diversity of words and may help children develop skills necessary to learn language, such as word segmentation and language processing.
      Words can be delivered in a variety of different ways in multiple different contexts. Parents and caregivers can narrate their daily activities, point out various objects in their environment, ask their baby questions about how he/she is feeling, and share books, nursery rhymes, and songs. All of these activities are ways in which parents or caregivers increase the quantity of words in their child's early language environment and thus enrich their learning potential (

      Power of Interactions

      Social relationships drive the need for an understanding of language and is an essential component of language learning. Language is the basis by which individuals are able to communicate with others and thus, language learning does not occur passively. Extensive research has shown the profound influence of social engagement for an infant's language development, and theories of social learning have emphasized the importance of social interaction for language learning (

      • Brooks R.
      • Meltzoff A.N.
      Infant gaze following and pointing predict accelerated vocabulary growth through two years of age: A longitudinal, growth curve modeling study.
      ). It is possible that contingent and reciprocal social behaviors, such as establishing joint attention, provides additional information to infants that help to scaffold their language development, including the provision of additional cues for communication intentions. Additionally, social interactions may help facilitate language learning through increased attention to the language being delivered; infant attention has been shown to be greater with a live person than a person via television or recordings (

      There are no scientific data to suggest that television, educational videos, or music recordings have the same positive, measurable impact on early childhood brain development as language from an interaction between an adult and child (
      • Weisleder A.
      • Fernald A.
      Talking to children matters: Early language experience strengthens processing and builds vocabulary.
      ). Infants have been found to learn language from adults in the context of an engaged adult–child interaction but not when the same information was delivered via a television (

      ). Although certain educational toys, recordings, and videos may provide learning enrichment for preschool-aged children, there are no data to support the claim that these educational materials have beneficial effects on infants and toddlers. In fact, evidence suggests the contrary, in that media may actually adversely affect the language development of infants and toddlers by limiting opportunities for parental language input and child speech (

      ). Thus, the back-and-forth communication exchanges between adult and baby is an essential component of language and brain development.

      Parentese

      Parentese, or infant-directed speech, is a style of communication that is used across various cultures and languages to talk with infants and young children (
      • Grieser D.L.
      • Kuhl P.K.
      Maternal speech to infants in a tonal language: Support for universal prosodic features in motherse.
      ). It uses actual words and sentences as opposed to “baby talk,” which simply mimics the sounds made by babies. It is characterized by varied intonation and prosody, elongated vowel and consonant sounds, repetition, and exaggerated gestures and facial expressions (
      • Grieser D.L.
      • Kuhl P.K.

      Home Language

      Home language refers to an individual's first language, or the language in which an individual is most fluent in. A growing number of children in the United States live in homes where a language other than English is spoken (
      National Center for Education Statistics
      English language learners in public schools. The condition of education (NCES-2016-144.
      ). Language exposure is most beneficial in the language the parent or caregiver is most comfortable speaking. Speaking in a nonfluent language generally leads to simpler and grammatically incorrect phrases and thus, the amount of language the child hears is significantly reduced (

      ).

      Interventions

      Efforts to promote early language exposure and improve children's language development have focused on training parents to read, talk, and interact more frequently with their child in a way that maximizes the developmental benefits of these shared experiences. Previously developed or existing interventions generally fell into at least one of five categories: (a) a book distribution program with anticipatory guidance for shared-book reading, (b) teaching dialogic reading techniques, (c) coaching parents to talk more with their child, (d) training parents to be responsive to their child's focus of attention and communication initiations, or (e) public awareness campaigns. Such programs are appropriate for enhancing literacy and language development, because evidence suggests that aspects of parent–child interactions associated with a child's language development include (a) amount of parent-child interaction, (b) amount and quality of linguistic input, (c) responsiveness of child's communication, and (d) the use of language-learning support strategies, such as book-reading (

      Factors that have contributed to the successful implementation and dissemination of interventions include the simplicity of the messaging; well-defined and straightforward mission and tasks; the support of the intervention within the pediatric profession; communicating about the intervention though published articles, media, continuing education courses; and the generation of data showing its effectiveness.
      All of the interventions discussed here use the concept of Language Nutrition. The goal for all of the programs is to enrich the language interactions that young children have with their caregivers. All of the programs reach their goals through Language Nutrition in various settings and with different pediatric providers and educators reaching the families. Although there are multiple ways in which parent-based interventions can be designed and delivered to parents, incorporating literacy and language promotion into pediatric primary health care represents a promising platform for the delivery of parent-based interventions for young children.

      Pequeños y Valiosos (Young and Valuable)

      Pequeños y Valiosos is a national public action campaign that aims to help optimize learning in everyday moments for Hispanic children under the age of 5 years by targeting parents/caregivers and broader Hispanic community (). Through a partnership with Univision, the leading media company serving the Hispanic population, and Too Small to Fail, a public awareness and action initiative of the Clinton Foundation that mobilizes communities to improve the health and well-being of young children, Pequeños y Valiosos delivers information to the Hispanic population across Univision platforms, radio and network programming, social media, and local community outreach to encourage talking, reading, and singing to children ().

      Reach Out and Read

      Reach Out and Read is a program that was started in 1989 to address low literacy skills by incorporating literacy promotion in pediatric primary care well-child visits for children 6 through 60 months old (

      ). Reach Out and Read includes the following three components, which are each aimed at supporting and encouraging shared reading between parents and young children: pediatric health care providers (a) provide anticipatory guidance to parents about shared reading and (b) distribute a culturally and developmentally appropriate book to the child at each well-child visit; (c) volunteers in waiting rooms of primary care clinics model reading with children and/or books are available for children to read in the waiting rooms (

      ).
      Reach Out and Read has developed into a nationwide early literacy intervention. With endorsements by the American Academy of Pediatrics, Reach Out and Read has been adopted by over 5,000 hospitals and health clinics throughout the United States, reaching 32% of children below the poverty level, and has been adapted in over a dozen countries (
      • Zuckerman B.
      • Khandekar A.

      Talk With Me Baby

      Talk With Me Baby (TWMB) is a statewide initiative in Georgia to dramatically transform the understanding, will, and skill of all parents and caregivers to become conversational partners with their babies and children (). This cross-sector coalition is integrating coaching about language-rich interactions as a core competency of two key large-scale workforces of trusted professionals that already serve most parents and babies—nurses and Women, Infants, and Children clinic nutritionists, who see 99% and 50% of all new and expectant parents in Georgia, respectively. TWMB has created a continuing education program to teach nurses how to coach parents on the provision of language-rich interactions and to encourage nurses to model language-rich interactions in their own interactions with infants and children (). TWMB has also developed resources for parents to use to encourage conversations with their young child, including a smartphone app called “Let's Talk!” and videos showing how parents can incorporate talking and interacting with their baby into their daily life. TWMB has partnered with Scholastic to produce books for children that emphasize the importance of language-rich interactions for a young child's literacy and language development. Currently, evaluation studies are being conducted to evaluate the efficacy of this initiative in both outpatient and inpatient settings.

      Thirty Million Words Initiative

      The Thirty Million Words (TMW) Initiative is a program designed to strengthen the ability of parent language to build a child's brain and narrow the achievement gap. This initiative is delivered at the individual, community, and population level through individual coaching, social media, and a public awareness campaign in Chicago, Illinois.
      The TMW project involves eight educational, computer-based modules delivered by a trained coach for 1 hour at weekly home visits (

      Implications for Practice

      The American Academy of Pediatrics issued its first policy statement addressing early child literacy in 2014, which established early literacy promotion, beginning in infancy, as an essential component of pediatric practice (
      • High P.C.
      • Klass P.
      Literacy promotion: An essential component of primary care pediatric practice.
      ). This policy recommends that pediatric health providers receive training about literacy promotion and that they provide anticipatory guidance about early literacy promotion and how parents can provide opportunities for their child to learn (
      • High P.C.
      • Klass P.
      Literacy promotion: An essential component of primary care pediatric practice.
      ).
      The workforce of pediatric nurses and nurse practitioners is well positioned to build the capacity of parents to interact with their infants and young children in a way that promotes language learning, given many scheduled touchpoints: the frequency and near universality of these visits allow for an intervention, or educational and health messages, to be delivered and reinforced on a regular basis by capitalizing on an already existing infrastructure. Pediatric nurses and providers are uniquely qualified to deliver messages regarding the importance of shared book reading, talking with a child, and engaging social parent–child interactions given that part of pediatric well-child visits includes assessment of developmental milestones, as well as parent education and anticipatory guidance on health and development.
      Pediatric health care providers can incorporate language promotion practices into everyday tasks in early childhood checkups, sick visits, or hospital stays.
      Pediatric health care providers can incorporate language promotion practices into everyday tasks in early childhood checkups, sick visits, or hospital stays. Coaching should include both the “why” and the “how” to engage in language-rich interactions and the demonstration of such an interaction. Strategies such as motivational interviewing and the teach-back method can help providers assess parents' understanding and will to engage in language-rich interactions with their child.

      Teaching “Why”

      As part of anticipatory guidance at well-child visits, pediatric health care providers discuss development and developmental expectations and assess whether the young child is meeting their developmental milestones. The American Academy of Pediatrics recommends that providers ask about shared book reading and television exposure, which could be a way to lead into discussing Language Nutrition (
      ).
      As mentioned, all parents and caregivers interact and communicate with their infant or young child, but disparities exist in the amount and quality of these interactions. Merely asking parents or caregivers whether they read or talk with their baby and saying that it is important that they do so will not convey the importance of Language Nutrition for their baby's future health and academic success. Research has shown that when parents understand the implications of their actions and understand child development, their behavior changes (
      • Suskind D.L.
      • Leffel K.R.
      • Graf E.
      • Hernandez M.W.
      • Gunderson E.A.
      • Sapolich S.G.
      • Levine S.C.
      A parent-directed language intervention for children of low socioeconomic status: a randomized controlled pilot study.
      ). Examples of messages to tell parents “why” can be found in Box 1.
      Teaching why
      • You have the ability to be your baby's first and best teacher simply by talking and interacting with him or her.
      • Talking with your baby builds your baby's brain.
      • Even if your baby is not able to talk yet, your baby is actively learning the words you speak.
      • Your baby is able to recognize your voice and is capable of learning language even before birth.
      • It is easier for your baby to learn at an early age because the brain is growing more rapidly in the first 3 years of life than at any other time.
      • The more words you speak to your baby, the more words he or she will know, which will help him or her do better in school.
      • Doing better in school leads to better health, a higher chance of graduating from high school/college, and a lower chance of imprisonment.
      • Talking with your baby is a great way to build an emotional bond.
      • By talking with your baby, you are teaching your baby how to engage socially with other people.
      • The single strongest action you can take to increase your child's educational opportunities is to talk with your baby.

      Teaching “How”

      In addition to understanding the importance of Language Nutrition for a child's health and educational trajectory, families need to be equipped with tools to implement practices into their daily lives. A powerful way to teach “how” is through modeling Language Nutrition with infants and children. Greet the baby or young child when entering the room and narrate the examination to the child. Direct questions and comments to the infant—realizing that parents will supply the answers. Directing the conversation to the baby provides families with an example to follow and reinforces the importance of Language Nutrition.
      Pediatric health care providers should tell families to make the baby their conversational partner as often as they can. As they go throughout their day, they can narrate what they are doing and point out objects in the environment as a way to introduce new words. Families should pay attention to the baby or young child's social and verbal communication, whether it be the child looking at something, pointing to something, babbling, or using actual words. Responding to the child's communication, even if it is nonverbal, and asking the child questions facilitates reciprocity and, thus, language learning in a social context. Reading children's story books and singing songs on a daily basis will help establish daily practices of literacy promotion. Additionally, families should be encouraged to speak using parentese and the home language. Messages to share with families about “how” can be found in Box 2.
      Teaching how
      • Talk with your baby every day and as much as you can.
      • Narrate daily activities to your baby, such as changing diapers, feeding, or bathing. Describe to your baby what you are feeling and doing.
      • Respond to your baby's lead. Tune in to what your baby looks at and the expressions and babbles your baby makes.
      • Ask your baby questions and encourage your baby to answer with facial expressions, gestures, coos, babbles, and words. This back-and-forth communication helps them learn.
      • Talk to your baby in a sing-song voice. This type of talking helps your baby learn words.
      • Use actual words when you talk with your baby.
      • Repeat words and phrases.
      • Praise your child when he or she communicates.
      • Talk with your baby in the language you are most comfortable using, because you will help your baby learn best by speaking in the language you know most.
      • Use gestures to communicate with your baby.
      • Introduce new vocabulary through singing, reading, and telling stories.
      • Avoid use of TV or music recordings for language development. TV and recordings do not help babies learn new words.
      • You do not need fancy toys, books, or to even know how to read to talk to your baby. You just need your words. Talk is cheap!
      • Encourage others who spend time with your baby to talk with your baby.
      Many of the established interventions highlighted in this article have Web sites that provide additional information and resources, including handouts, educational curricula, and early literacy milestone checklists and videos for health care providers and/or parents. Web sites of the interventions are listed in the Table.

      Conclusion

      The ability to provide Language Nutrition is crucial for shaping the social, learning, and health outcomes of young children (

      ). All parents and caregivers are capable of being their baby's first and best teacher; all parents know how to talk and can talk, either verbally or through sign language. Toys and books are not necessary for a family to be successful in influencing their child's chances for academic success. Consistent with evidence, the single most important action a parent can take to positively influence their child's future health and educational trajectory is to talk with their children (). By sharing these messages with families, pediatric health care providers can build the capacity of families to talk with their children in a way that promotes their linguistic, cognitive, and social development. Thus, pediatric providers have the potential to leverage dramatic results for children's academic and health outcomes and be partners in the efforts to close the nation's educational achievement gap.
