Language Development and Literacy. IntroductionThe acquisition of language is one of the more remarkable achievements of early childhood. By age 5, children essentially master the sound system and grammar of their language and acquire a vocabulary of thousands of words.
This report describes the major milestones of language development that typically-developing, monolingual children achieve in their first 5 years of life and the mechanisms that have been proposed to explain these achievements.
SubjectYoung children's language skills are important to their interpersonal and academic success. Recent Research ResultsThe course of language development and its underlying mechanisms are usually described separately for the subdomains of phonological development the sound system , lexical development the words , and morpho-syntactic development grammar , although these domains are interrelated both in language development and in language use.
Phonological development. Newborns have the ability to hear and discriminate speech sounds. This tuning of speech perception to the ambient language is the result of a learning process in which infants form mental speech sound categories around clusters of frequently-occurring acoustic signals. These categories then guide perception such that within category variation is ignored and between category variation is attended to.
When first words appear, they make use of the same sounds, and they contain the same numbers of sounds and syllables, as the preceding babbling sequences. In babbling, infants may be discovering the correspondence between what they do with their vocal apparatus and the sounds that come out. The important role of feedback is suggested by findings that children with hearing impairment are delayed in achieving canonical babbling.
At approximately 18 months, children appear to have achieved a mental system for representing the sounds of their language and producing them within the constraints of their articulatory abilities. Lexical development. Infants understand their first word as young as 5 months, produce their first words between 10 and 15 months of age, reach the word milestone in productive vocabularies around 18 months of age, and the word milestone between 20 and 21 months.
The vocabulary size of an average 6-year-old has been estimated at 14, words. Children begin to put two, then three and more words together into short sentences at approximately 24 months of age. Children's first sentences are combinations of content words and are often missing grammatical function words e. As children gradually master the grammar of their language, they become able to produce increasingly long and grammatically complete utterances.
The development of complex i. In general, comprehension precedes production. It is argued that children come to the language-learning task equipped with innate knowledge of language structure and that language could not be achieved otherwise. It is also clear, however, that children have the ability, even in infancy, to detect abstract patterns in the speech they hear, 19 and there is very strong evidence that children who hear more speech and who hear structurally more complex speech acquire grammar more rapidly than do children with less experience 3,20which suggests that language experience plays a substantial role in language development.
Research GapsOne gap or disconnect in the field is between the theoretically-driven quest to account for the universal fact of language acquisition and the applied need to understand the causes of individual differences in language development.
Relatedly, there is less research on minority populations and on bilingual development than on monolingual development in middle-class samples.
This is a serious gap because most standardized assessment tools are not suited to identifying organically-caused delay in minority children, in children from low socioeconomic strata, or in children acquiring more than one language.
ConclusionsThe course of language development is very similar across children and even across languages, suggesting a universal biological basis to this human capacity.
The rate of development varies widely, however, depending both on the amount and nature of children's language experience and on children's capacities to make use of that experience. ImplicationsNormally-endowed children need only to experience conversational interaction in order to acquire language.
Many children, however, may not experience enough conversational interaction to maximize their language development. Parents should be encouraged to treat their young children as conversational partners from infancy. Educators and policy IntroductionLearning to talk is one of the most visible and important achievements of early childhood.
In a matter of months, and without explicit teaching, toddlers move from hesitant single words to fluent sentences, and from a small vocabulary to one that is growing by six new words a day.
New language tools mean new opportunities for social understanding, for learning about the world, and for sharing experiences, pleasures and needs. SubjectThe nature of language knowledge Language development is even more impressive when we consider the nature of what is learned. It may seem that children merely need to remember what they hear and repeat it at some later time.
But as Chomsky 1 pointed out so many years ago, if this were the essence of language learning, we would not be successful communicators. Verbal communication requires productivity, i.
This endless novelty requires that some aspects of language knowledge be abstract. Ultimately, "rules" for combining words cannot be rules about particular words, but must be rules about classes of words such as nouns, verbs or prepositions. Once these abstract blueprints are available, the speaker can fill the "slots" in a sentence with the words that best convey the message of the moment. Chomsky's key point was that since abstractions cannot ever be directly experienced, they must emerge from the child's own mental activity while listening to speech.
Problems and ContextThe debate The nature of the mental activity that underlies language learning is widely debated among child language experts. One group of theorists argues that language input merely triggers grammatical knowledge that is already genetically available. Research Results Predictable language sequencesIn broad strokes, the observable "facts" of language development are not in dispute. Most children begin speaking during their second year and by age two are likely to know at least 50 words and to be combining them in short phrases.
They also learn how to create, and maintain, larger language units such as conversation or narrative. Theorists differ in the emphasis and degree of determination posited for a given domain, but most would agree that each is relevant. There is a large body of research supporting the view that language learning is influenced by many aspects of human experience and capability. I will mention two findings in each area that capture the flavour of the available evidence. Social1-Toddlers infer a speaker's communicative intent and use that information to guide their language learning.
For example, as early as 24 months, they are able to infer solely from an adult's excited tone of voice and from the physical setting that a new word must refer to an object that has been placed on the table while the adult was away. From ages one to three, children from highly verbal "professional" families heard nearly three times as many words per week as children from low verbal "welfare" families.
Longitudinal data show that aspects of this early parental language predict language scores at age nine. Auditory perceptual skills at six or 12 months of age can predict vocabulary size and syntactic complexity at 23 months of age. In English, the forms that are challenging for impaired learners are forms with reduced perceptual salience, e.
Children who hear an unusually high proportion of examples of a language form learn that form faster than children who receive ordinary input.
For example, children make more errors on small grammatical forms such as verb endings and prepositions in sentences with complex syntax than in sentences with simple syntax. Words that express notions of time, causality, location, size and order are correlated with mental age much more than words that simply refer to objects and events.
Children who have difficulty recalling a word also know less about the objects to which the word refers. If a verb ends in -ing, three-year-olds will decide that it refers to an activity, such as swim, rather than to a completed change of state, such as push off.
Toddlers usually decide that a new word refers to the object for which they do not already have a label. Children come to the task of language learning with perceptual mechanisms that function in a certain way and with finite attention and memory capacities. These cognitive systems will, at the least, influence what is noticed in the language input, and may well be central to the learning process. Similarly, children's prior experience with the material and social world provides the early bases for interpreting the language they hear.
Later, they will also make use of language cues. The course of language acquisition is not, however, driven exclusively from within. The structure of the language to be learned, and the frequency with which various forms are heard, will also have an effect. Despite the theoretical debates, it seems clear that language skills reflect knowledge and capabilities in virtually every domain and should not be viewed in an insular fashion. Educational and Policy ImplicationsEducators and policy-makers have often ignored preschoolers whose language seems to be lagging behind development in other areas, arguing that such children are "just a bit late" in talking.
The research evidence suggests instead that language acquisition should IntroductionRecent advances in neuroimaging allow for the investigation of the neurobiological bases of language and the effects of environmental and genetic factors on neural organization for language in children.
Increasingly, these methods are being used to characterize the developmental timecourse of different language subsystems and to more precisely examine the effects of language experience, and the timing of these effects, on the development of different language functions and on the neural mechanisms which mediate these subsystems.
SubjectAn understanding of the neurobiology of language development has important implications for those seeking to optimize language development.
Insights from this research have the potential to provide practical, evidence-based advice for parents. In addition, evidence from this research can help educators and policymakers identify, develop and adopt evidence-based language and literacy curricula for both first and second language learners. ProblemsThe rates of language development vary substantially among children, and this variability is a product of a complex interaction between genetic and environmental factors.
This research seeks in part to characterize the relative contributions of genetic and environmental factors to these differences in development. While much behavioral evidence exists concerning the effects of environmental factors on language development, less evidence exists on the effects of environmental factors on the neurobiology of language development. Most previous research on the neurobiology of language in adults as well as on the neurobiology of language development has focused on middle to higher socioeconomic status SES individuals.
Additionally, little evidence currently exists which specifically addresses the contribution of genetic and epigenetic factors to these differences in development. These techniques have also been used to investigate the neurobiological bases of language development, though less evidence exists on the effects of environmental factors on the neurobiology of language development.
Based in large part on a substantial body of evidence from behavioral studies of language development, research on the neurobiology of language development is now expanding in scope to include children and adults from a wider range of SES backgrounds. Key Research QuestionsOne key research question involves the use of neuroimaging techniques to characterize the timecourse of the development of neural substrates which subserve different subsystems of language.
A related key question involves the use of these techniques to characterize the effects of environmental and genetic factors, and the interaction between the two, on the development of these neural substrates. An important aspect of this question is the investigation of the time periods during which the effects of environmental and genetic factors are maximal i. Recent Research ResultsStudies of the development of the neurobiological bases of language have provided evidence on the developmental timecourses of three linguistic subsystems, specifically phonology sound system of the language , semantics vocabulary and word meanings , and syntax grammar.
This research also provides evidence that brain responses to language at early ages are predictive of later language proficiency. Most of this evidence comes from studies using ERPs, which is better suited for use with children as young as infants, although neuroimaging methods such as fMRI are increasingly being used with younger populations.

Language skills are receptive—the ability to listen to and understand language—and expressive—the ability to use language to communicate ideas, thoughts, and feelings. Children's language ability affects learning and development in all areas, especially emerging literacy. For infants and toddlers, emerging literacy is embedded in the Language and Communication domain. For preschoolers, Language and Literacy are distinct domains. Language and literacy skills can develop in any language, and for the most part, they develop first in the child's home language.

Language and literacy development are major domains of early childhood development. They involve development of the skills used to communicate with others through languages language development , as well as the ability to read and write literacy development. An example of language and literacy development in childhood learning is to speak the native language of one's parents and read basic words in that language.

Results indicated that coaching appears to be an effective form of professional development for early childhood educators.
As early childhood education moves front and center in the public policy debate, more attention is being paid to early literacy. Early childhood professionals have long recognized the importance of language and literacy in preparing children to succeed in school. Early literacy plays a key role in enabling the kind of early learning experiences that research shows are linked with academic achievement, reduced grade retention, higher graduation rates and enhanced productivity in adult life. This report synthesizes the body of professional knowledge about early literacy and offers research-based recommendations. A growing body of evidence shows that early learning experiences are linked with later school achievement, emotional and social well-being, fewer grade retentions, and reduced incidences of juvenile delinquency and that these outcomes are all factors associated with later adult productivity. An analysis of the research literature indicates specific skills and abilities of children ages birth through 5 years that predict later reading outcomes. Other less significant indicators include: Rapid Automatic Naming RAN ; visual memory; and visual perceptual abilities.
This section presents a developmental perspective of literacy learning. It highlights the movement from code breaking to meaning making to critical thinking. Considering language and literacy as developmental is really quite fundamental for us. Instead, we are noting an emphasis on observing how the capacity of a learner or a group or a class or a community matures over time, but not necessarily so. There should be a progressive, temporal dimension to this learning where the child is supported by others to develop foundational skills which lead into competencies which lead to mastery which leads to further disciplinary practices. We need to marvel at how learning transpires and how each new act of learning builds from that which came before. We need to marvel at the small steps and giant leaps that occur.
