    • Definitions of language : 

        For a start, let us take a look at the various definitions by applied linguists:

      -“Language is a purely human and noninstinctive method of communicating ideas, emotions, and desires by means of a system of voluntarily produced symbols” (Sapir, 1921)

      -“A language is a system of meaning – a semiotic system.” (Halliday, 2003: 2)

      -“language as a finite system of elements and principles that make it possible for speakers to construct sentences to do particular communicative jobs” (Fasold & Connor-Linton, 2006)

      -“Language as a tool for communication” (Nunan, 2007)

      -“language, a system of conventional spoken, manual (signed), or written symbols by means of which human beings, as members of a social group and participants in its culture, express themselves.” (Robins and Crystal, 2021)

         A language is a system of conventional spoken, manual (signed), or written symbols by means of which beings express themselves. The more complex a language is, the more varied its display of functions and characteristics. The typical functions of language include communication, the expression of identity, play, imaginative expression, and emotional release.

         Many definitions of language have been proposed. Henry Sweet, an English phonetician and language scholar, stated: “Language is the expression of ideas by means of speech-sounds combined into words. Words are combined into sentences, this combination answering to that of ideas into thoughts.” The American linguists Bernard Bloch and George L. Trager formulated the following definition: “A language is a system of arbitrary vocal symbols by means of which a social group cooperates.” (Robins & Crystal ,2004)

       Language is a representation of thought :

         Of all the definitions of language, this is perhaps the most distant one from how majority of people defined language. It is also a contentious one which can invite fierce debates among linguists. As highlighted by Sapir (1916), “Language and our thought-grooves are inextricably related, are, in a sense, one and the same”.

      Conclusion: Representing LANGUAGE for our learners

          we have journeyed through 5 different definitions of language. They represent the meaning of language for us and our learners. On one hand, they influence the way we learn language. On the other hand, they also provide different perspectives on the nature of language and its relevance to us as humans, and continue to drive us in presenting the different aspects of language to our learners.

    • Importance of Language :

      Language is a vital part of human connection. Although all species have their ways of communicating, humans are the only ones that have mastered cognitive language communication. Language allows us to share our ideas, thoughts, and feelings with others. It has the power to build societies, but also tear them down. It may seem obvious, but if you’re asking yourself, why is language important? You’ll have to break it down to truly understand why.

      ·         Language Is Important To Culture And Society. ...

      ·         Language Is Important To Business. ...

      ·         Language Is Important For Individuals And Development. ...

      ·         Language Is Important For Personal Communication. ...

      Functions of Language :

      ·         What utterances make up our daily verbal communication? Some of our words convey meaning, some convey emotions, and some actually produce actions. Language also provides endless opportunities for fun because of its limitless, sometimes nonsensical, and always changing nature. In this section, we will learn about the five functions of language, which show us that language is expressive, language is powerful, language is fun, language is dynamic, and language is relational.

      Language Is Expressive

      Verbal communication helps us meet various needs through our ability to express ourselves. In terms of instrumental needs, we use verbal communication to ask questions that provide us with specific information. We also use verbal communication to describe things, people, and ideas. Verbal communication helps us inform, persuade, and entertain others, which as we will learn later are the three general purposes of public speaking. It is also through our verbal expressions that our personal relationships are formed. At its essence, language is expressive. Verbal expressions help us communicate our observations, thoughts, feelings, and needs (McKay, Davis, & Fanning, 1995).

      Language Is Powerful

      The contemporary American philosopher David Abram wrote, “Only if words are felt, bodily presences, like echoes or waterfalls, can we understand the power of spoken language to influence, alter, and transform the perceptual world” (Abram, 1997). This statement encapsulates many of the powerful features of language. Next, we will discuss how language expresses our identities, affects our credibility, serves as a means of control, and performs actions.

         Language skills are essential to a child’s ability to communicate and develop. These skills enable children to engage with other people and learn from their surroundings and in the classroom.

      Language skills are about children learning the rules for putting words together in a way that will express their thoughts and feelings and understanding the meaning of both the written and spoken word.

      Language is made up of four main areas, which include:

      1. Phonology - The way sounds are structured and sequenced in speech
      2. Semantics - How vocabulary is used to express concepts
      3. Grammar - This involves syntax, which is the way words are arranged to for m a sentence, as well as morphology, which is the use of grammar to express tense or the active voice, for example.
      4. Pragmatics - The skills used to communicate effectively such as waiting your turn to speak, adapting language based on the person you are speaking to and how to ask for something or greet someone.

      The first five years of a child’s life are the most important in terms of language development, although they continue to develop through the rest of childhood and into adolescence. During the first five years, new nerve cells grow and connect in the brain that enable the child to use language for self expression . It is therefore important that the child is stimulated during this time, to ensure their progress is not slowed and their communication skills are not affected.

      Although each child develops language skills at their own pace, there are some general milestones that can act as indicators that language is developing normally. Healthcare professionals use these indicators as a guide when assessing whether a child may need any extra assistance.


         

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       

       


    • Factors affecting the development of speech and language in children :

          The development of speech, language, and literacy in children is a remarkable journey. It's a process that starts from the moment a child is born and continues to evolve throughout their life. This blog explores the multifaceted factors that influence this development and how they shape a child's ability to communicate effectively and become literate.

      Early Language Exposure:

      Language development often begins at home. Children who are exposed to rich, diverse language from an early age tend to have an advantage. Parents, caregivers, and family members play a vital role in modeling language and engaging in conversations with young children. The more words a child hears and the more interactions they have, the better their language skills develop.

         Studies have shown the importance of early exposure to language in the early years. But children, in fact, spontaneously tend to listen to and imitate languages, and she also showed that even without words, babies cry and communicate with an “accent.”

      Genetics and Neurobiology:

      A child's genetic makeup and neurobiological factors also come into play. Some children might be more predisposed to certain language-related challenges, while others have a natural aptitude for language. Understanding the genetic and neurobiological aspects of language development can help tailor interventions to specific needs.

         Researchers have found evidence that genetic factors may contribute to the development of language during infancy. Scientists discovered a significant link between genetic changes near the ROBO2 gene and the number of words spoken by children in the early stages of language development.

      Hearing and Sensory Perception:

      Hearing is a cornerstone of language development. Children with hearing impairments face unique challenges, but early intervention with hearing aids or cochlear implants can significantly mitigate these obstacles. Sensory perception, including the ability to perceive and interpret sensory information, also plays a role. Sensory processing disorders can impact a child's language development.

      Hearing sounds and words helps children learn to talk and understand. A child with hearing loss misses out on these sounds. This can cause problems with speaking, reading, school success, and social skills. It is important to have your child tested if you think they have trouble hearing.

         Auditory perception also plays a crucial role in understanding the rules of syntax and grammar. Children need to be able to hear the differences in sentence structures, verb tenses, and word order to develop their understanding of how language works.

      Social Interaction:

      Interaction with peers and adults is crucial for language development. Children learn through observing, imitating, and practicing in social contexts. Thus, opportunities for interaction, both structured and unstructured, are vital for honing communication skills.

      Peer social interactions, or social play, are believed to be beneficial for young children as they provide a key mechanism through which children develop language, cognitive, and social skills, as they learn to modify, monitor, and evaluate their emotions, and develop their divergent thinking skills via exposure to ...

      Educational Environment:

      Preschool and school environments play a substantial role in language and literacy development. Qualified educators who use evidence-based teaching methods can significantly impact a child's progress. Inclusive classrooms that support diverse learners are particularly beneficial.

      Environment also plays important role in determining the second language acquisition of language learner. It includes everything the language learner hears and sees in the new language.

      The environment plays a role in language development if the child is shy or emotionally reactive If a child is shy or emotionally reactive, they will express or acquire language more slowly. The more words caregivers use, the larger a child's vocabulary will be. Children with lower socioeconomic status tend to have smaller vocabularies. Language develops better in children who are read to regularly.

    • Theories of Language Acquisition :

      Theories of Language Acquisition :

         There are 4 main theories of language acquisition that we learn in English Language. These are:

         There are also certain theorists of language development who have contributed to the development or further study of a certain language acquisition theory.

      Theorists of Language Development

      Language Acquisition Theory

      BF Skinner

      Behavioural Theory

      Jean Piaget

      Cognitive Theory

      Noam Chomsky

      Nativist Theory

      Jerome Bruner

      Interactionist Theory


      Behavioural theory (BF Skinner theory of language acquisition)

         The Behavioural theory of language acquisition, sometimes called the Imitation Theory, is part of behaviourist theory. Behaviourism proposes that we are a product of our environment. Therefore, children have no internal mechanism or ability to develop language by themselves. BF Skinner (1957) suggests that children learn the language first by imitating their caregivers (usually parents) and then modifying their use of language due to operant conditioning.

      What is operant conditioning?

      Operant conditioning is a way of learning that focuses on the reward (positive reinforcement) or punishment (negative reinforcement) of desired or undesired behaviour.

      Example :

      You can train a dog to sit by feeding it a treat when it obeys your commands, or you can stop it from sleeping on your bed by ignoring it or verbally discouraging it.

      How does operant conditioning apply to language acquisition?

         Skinner suggested that children first learn words and phrases from their caregivers or others around them and eventually try to say and use those words correctly. In this case, operant conditioning occurs when a caregiver responds to the child's attempt at using language. If the child uses language correctly, the caregiver may respond by telling the child they're clever or otherwise showing their approval. If the child makes a request, such as asking for food, the caregiver may reward the child by providing it. This is positive reinforcement.

      If the child uses language incorrectly, makes a mistake, or is incoherent, they are more likely to receive negative reinforcement from the caregiver. They can be told they're wrong and then be corrected or simply be ignored. Negative reinforcement teaches the child which mistakes to avoid and how to correct them.

      Cognitive theory (Jean Piaget theory of language acquisition)

      The Cognitive theory of language acquisition suggests that the primary drives behind our actions are our thoughts and internal processes. Jean Piaget (1923)

      Piaget believed that cognitive development had to come before language development because it would be impossible for children to express things that they don't yet understand. For example, a younger child with no sense of time couldn't express things in the future tense or speak hypothetically, no matter how much they are taught language.

      Piaget proposed that this cognitive development could be split into four stages:

      Piaget's four stages of cognitive development

      First is the

      The next stage is the pre-operational stage, which takes place from ages two to seven.

      Next is the concrete operational stage. It takes place from ages seven to eleven.

      Finally, we have the formal operational stage.

      Nativist theory (Noam Chomsky theory of language acquisition)

         Noam Chomsky (1957) proposes that children are born with an instinct or drive for language learning which he calls the language acquisition device (LAD).

      What is the language acquisition device?

      Chomsky suggests that the language acquisition device (LAD) must be located somewhere in the brain, serving as an encoder that provides us with a baseline understanding of grammatical structure.

      Chomsky argues that this independent 'building' of language is evidence that language acquisition is biological and not purely a product of being taught or copying caregivers. Chomsky suggested that the LAD contained knowledge of universal grammar

      Interactionist theory (Jerome Bruner theory of language acquisition)

         Jerome Bruner (1961) believed that children are born with an ability to develop language but they require regular interaction with their caregivers or teachers to learn and understand it to a level of full fluency. This idea is known as the Language Acquisition Support System (LASS).

      Caregivers tend to correct mistakes that children make when using language and also regularly teach them what objects are and what their purposes are.

      A caregiver may also use child-directed speech (CDS), altering their own use of language to make it easier for a child to conceptualise language independently.

      What is CDS and how does it aid language acquisition?

      CDS or child-directed speech is commonly known as ‘baby talk’ in everyday life. simple sentence structure. These strategies all simplify language to make it as easy as possible for the child to understand.

      Bruner believed that CDS was adapted to make language more simple, accessible, and easy to understand. According to this theory, children cannot develop an understanding of the more complex parts of language alone. Thus, CDS acts as an infant-friendly introduction to language that can be built on throughout infancy, early childhood, and into school.

      Theories of Language Acquisition - Key takeaways

      • The four theories of language acquisition are BF Skinner's behavioural theory, Piaget's cognitive development theory, Chomsky's nativist theory, and Bruner's interactionist theory.
      • BF Skinner believed that children learned language by imitating caregivers and responding to positive or negative reinforcement in a process known as operant conditioning.
      • Piaget believed that children must first develop cognitive faculties before they can develop language.
      • Chomsky believed that children are born with an innate ability to acquire language, due to the 'language acquisition device' which is thought to be a language encoder in the brain.
      • Bruner believed that children are born with some capacity for language acquisition, but require attention and support from caregivers in order to develop language fully. This idea is known as the language acquisition support system (LASS).

    • Language development :

         Language development is the process through which children acquire the ability to process speech and communicate. During this process, a child may slowly understand basic linguistic patterns and expand their vocabulary gradually before achieving fluency.

      Why is language development important?

         As a teacher, child care provider or speech-language pathologist, your understanding of the stages of language development helps you promote a child’s healthy development. You can create goals for them and intervene if they haven’t achieved the proper milestones for their age. Here are some other reasons why language development is important:

      - Promote social interaction

      - Improve cognitive development

      - Aid self-expression

      - Enhance literacy

      - Improve self-esteem

      What are the stages of language development?

         There are several stages of language development. These stages are typically understood to consist of pre-linguistic and linguistic categories.

      The pre-linguistic stage is the first of the stages of speech development. This stage is followed by the babbling stage, the first words stage, the two-word stage, and the telegraphic stage.

      Stage

      Language skills

      Pre-linguistic

      Cooing

      Babbling

      Syllable cycles

      First words

      Attaching meaning to words

      Two-word

      Discovering syntax

      Telegraphic

      Truncated language

      Pre-linguistic stage

         Also known as the pre-linguistic stage, the first stage of language development often occurs

      between zero and six months. Children in this phase don't have developed language skills,

      so they communicate with sounds. They cry, make cooing sounds and utter nasal murmurs

      as their vocal tracts develop. Infants can also recognize voices and sounds in addition to

      facial expressions and voice tones.   

      Babbling stage :

      The second stage of a child's language development happens between the ages of 6 and 9 months. Children begin to babble, making noises and syllables that aren’t yet words. Mouth muscles and teeth grow to prepare children for more advanced talking.

         At this stage, infants begin to explore the properties of sounds through production. The sounds of early babbling are universal. However, by the time a child reaches the age of 8 months, a drift occurs in the characteristics of babbling (Helms-Park, 2018). Babbling becomes more distinctive. Infants begin to make sounds that would only occur in their own native languages.

      A French baby and an American baby will not babble the same, as there are certain sounds that English and French do not share. At this stage, parents should expect their children to go through three phases. They follow:

      1.      One consonant and a vowel at a time. Example: “ma,” “da,” “du,” “bi”

      2.      Reduplicative babbling. Example: “da-da-da-da”

      3.      Non-reduplicative babbling. Example: “ba-du-ba-du.”

      In these phases, the most frequent vowels and consonant sounds that are produced by English babies are: ‘i’, ‘u’, ‘a,’ and ‘b’, ‘d’, ‘g’, and ‘m’. Vowels are generally easier to produce than consonants, as they do not require many obstructions in the vocal or nasal tract.

       Holophrastic stage : (One-word Stage)

         The third phase of language development, also known as the holophrastic stage, usually happens between the ages of 9 and 18 months. During this time, their language skills usually have increased enough for them to say single words that describe objects or identify their basic needs. For instance, a child in this stage might say "dada" as a way of getting their dad's attention. 

         During this stage, children begin to acquire and produce real words of their native languages. A child in this stage will use single-word constructions to communicate. The use of single-word items is meant to convey full sentences provided the context.

      As expected, word productions are extremely redundant. The one-word productions have three functions:

      1.      Express emotions: “uh-oh,” “bad”

      2.      Request a desired action: “up,” “down,” “gimme”

      3.      Name objects: “baba” (bottle), “truck,” “doggie,” “mine”

      At this stage, children know the meanings of words that they say, as speaking is often accompanied by finger-pointing (Helms-Park, 2018).

      Two- word stage : 1.5- 2 years old :

         During this stage, the child can speak two-word sentences that usually have some meaning. They group words together that they learned during the holophrastic stage. Some examples may include:

      Saying "more food" at the table

      Saying "doggy small" to describe a dog

      Saying "thank mom!" to show appreciation

         Children usually enter this stage when they have acquired about 50 words. They begin to demonstrate their knowledge of the word order that occurs in their language. English has a SUBJECT VERB OBJECT (SVO) word order. It is very common for production to take the following structures:

      1.      Doer + action: “Tommy play”

      2.      Action + affected object: “Kick ball”

      3.      Possessor + possessed object: “Daddy key”

      4.      Negation/Refusal/ Cessation of existence: “No veggie,” “all gone milk”

         At this stage, lots of verbs, nouns, and adjectives emerge, as well as intonation! Intonation is a clear indication that children do not perceive speech production as one chunk, but rather as individual words coming together to convey a more complex meaning.

      5. Telegraphic stage :

         The telegraphic stage occurs between the ages of 24 and 30 months. Children can speak phrases that are not only longer but also have more than two elements. For instance, a child might say “The cat stand up on the table.” Correct grammar still isn’t prevalent in this stage, but the sentence conveys that the cat is standing up in addition to being on the table. The child also develops the ability to understand basic instructions, including two-part orders like "go to your table and get your books."

      At this stage, children experience a vocabulary spurt or “explosion.” Production is pidgin-like, as grammatical/function words (little words) such as ‘the,’ ‘a,’ ‘is,’ ‘will,’ ‘of,’ ‘by,’ pluralization, tense (past -ed), verb endings/person agreements (she eat ‘s’) are omitted.

      During this stage, a child will primarily communicate with content words (verbs, nouns, adjectives) and some pronouns such as ‘me’ and ‘mine.’

      Although many function words are missing at this stage, children obey the word order and structure of their language. Considering the English word order (SVO), English speaking children are expected to produce phrases similar to the following sentences:

      ·         “Want more ice-cream.”

      ·         “Mommy go bye-bye.”

      ·         “He go play.”

      The after Telegraphic Stage : (2,6 +years old)

      Early in this stage, complete sentences begin to emerge. Imperative and declarative sentences appear first (Helms-Park, 2018):

      1.      Imperative (command): “Give me my toy.”

      2.      Declarative (Relay information): “That’s my toy truck.”

      Coordination (acquired first) and subordination sentences also appear early in this stage, however, they are mastered by 4-5-years-old (Helms-Park, 2018):

      1.      Coordination (Two clauses joined in a symmetrical relation): “I am tall, but she is short.”

      2.      Subordination (Two clauses joined in a non-symmetrical relation): “When I am older, I am going to be bigger.”

      Progression of more complex questions and negatives appear between 2.6- 3.0-years-old (Helms-Park, 2018). By a child’s 3rd birthday, they begin to use more grammatical/function words, such as regular plural ‘-s,’ endings on verbs ‘-ing,’ prepositions (of, in, by), but third person agreement comes a bit later “She lovecandy.”  Near the end of this stage, almost everything is acquired between the ages of 5-6 (Helms-Park, 2018).

      Conclusion :

      Given this guideline of language acquisition, parents should note that kids are different in their rate of language development. A child who may be behind does not necessarily indicate a language impedimentAgain, every child is unique and different. Some may acquire language faster than others.

      It is always important to be mindful that comprehension of language always precedes production by some months. Language competence does equate to production. Most children who encounter delays in language development, including auditory impediments, usually catch up with their peers by the age of 3 (DeLuzio, 2020).

    • Terminology:

       language development :

         Language development in children is the process through which we gain the ability to comprehend and communicate through speech. Before acquiring fluency, a child may progressively comprehend fundamental verbal patterns and increase their vocabulary throughout this stage. Additionally, language development can be defined as, the process of developing the capacity to speak, which starts with the children hearing and understanding the pitch of the mother's voice and culminates with the child being able to use words effectively to transmit thoughts and desires.

      Language acquisition :

        Language acquisition is the process by which humans acquire the ability to comprehend and produce language, either as their first or second (third, etc.) language. The study of language acquisition provides evidence for theoretical linguistics and has practical applications in language pedagogy.

       Language delay :

         A language delay occurs when a child’s language is developing slower than other children of the same age, but it is following the typical pattern of development.

         A language delay is a type of communication disorder. Your child may have a language delay if they don't meet the language developmental milestones for their age. Their language abilities may be developing at a slower rate than most children's. They may have trouble expressing themselves or understanding others.

      Voice disorders :

        Voice disorders are vocal deficits that affect functional or daily communication needs.

        Voice disorders affect the ability to speak normally. These disorders can include laryngitis, paralyzed vocal cords, and a nerve problem that causes the vocal cords to spasm. Your voice may quiver, be hoarse, or sound strained or choppy. You may have pain or a lump in your throat when speaking.

      Articulation disorder :

         Articulation disorder is a common condition when your child can’t make specific sounds. For example, they may always replace “r” with “w” or “th” with “s.” The disorder isn’t related to any issues with their brain, mouth or hearing. A speech-language pathologist can diagnose the condition and help your child communicate clearly using speech therapy.

      Stuttering:

         Stuttering is a speech disorder characterized by repetition of sounds, syllables, or words; prolongation of sounds; and interruptions in speech known as blocks. An individual who stutters exactly knows what he or she would like to say but has trouble producing a normal flow of speech. These speech disruptions may be accompanied by struggle behaviors, such as rapid eye blinks or tremors of the lips. Stuttering can make it difficult to communicate with other people, which often affects a person’s quality of life and interpersonal relationships. Stuttering can also negatively influence job performance and opportunities, and treatment can come at a high financial cost.

      Autism Spectrum Disorder (ASD) :

        Autism spectrum disorder (ASD) is a developmental disability caused by differences in the brain. Some people with ASD have a known difference, such as a genetic condition. Other causes are not yet known. Scientists believe there are multiple causes of ASD that act together to change the most common ways people develop. We still have much to learn about these causes and how they impact people with ASD.

       Deafness :

         Hearing impairment, deafness, or hearing loss refers to the total or partial inability to hear sounds. There are many causes and types of deafness.

        Deafness, or hearing loss, happens when one or more parts of the ear aren't working effectively. To understand this, it's useful to know how the ear works.

      Aphasia :

         Aphasia is a disorder that results from damage to portions of the brain that are responsible for language. For most people, these areas are on the left side of the brain. Aphasia usually occurs suddenly, often following a stroke or head injury, but it may also develop slowly, as the result of a brain tumor or a progressive neurological disease. The disorder impairs the expression and understanding of language as well as reading and writing. Aphasia may co-occur with speech disorders, such as dysarthria or apraxia of speech, which also result from brain damage.

      Dyslexia :

         Dyslexia is a learning disorder that involves difficulty reading due to problems identifying speech sounds and learning how they relate to letters and words (decoding). Also called a reading disability, dyslexia is a result of individual differences in areas of the brain that process language.

         Dyslexia is not due to problems with intelligence, hearing or vision. Most children with dyslexia can succeed in school with tutoring or a specialized education program. Emotional support also plays an important role.

      Dysgraphia :

         Dysgraphia is a neurological condition and learning difference in which someone has difficulty with writing for their age level.

         Dysgraphia is a term that refers to trouble with writing. Many experts view dysgraphia as challenges with a set of skills known as transcription. These skills — handwriting, typing, and  spelling — allow us to produce writing.

         Trouble expressing your thoughts in writing isn’t formally recognized as part of dysgraphia. That’s a learning disability known as written expression disorder. But when people struggle with transcription, it can get in the way of thinking about ideas and how to convey them. 

      Dyscalculia :

         Dyscalculia is a learning disability in math. People with Dyscalculia  have trouble with math at many levels. They often struggle with key concepts like bigger vs. smaller. And they can have a hard time doing basic math problems and more abstract math.

      Intellectual disability :

         Intellectual disability (ID), also known as general learning disability and mental retardation, is a generalized neurodevelopmental ..
