How REET asks this topic

REET 2024 had 2 questions on language development, both based on factors affecting language development and ways of early expression, not directly on the definition of a theory. So understand properly the stages of language development and the factors (both positive and negative) that affect it.

Theories of language development

Behaviourist view (Skinner) — Language is learnt entirely through imitation, reinforcement and the environment; there is no innate ability.

Nativist view (Chomsky) — According to Noam Chomsky, every child is born with a 'Language Acquisition Device' (LAD), which enables them to quickly learn the grammar of any language (Universal Grammar). Chomsky argues that children correctly use sentence rules that were never taught to them (the 'poverty of stimulus' argument), so language cannot be learnt through imitation alone.

Socio-cultural view (Vygotsky) — Language develops through social interaction and shapes the thinking process.

Rather than treating these three views as opposed to each other, REET usually understands that innate ability, stimulation from the environment, and social interaction all play a role in language development; no single factor alone can fully explain it.

Key stages of language development

Cooing
Around 2-4 months — vowel sounds (such as 'aah', 'ooh')
Babbling
From about 6 months — repetition of consonant-vowel sounds ('ba-ba', 'ma-ma')
One-word/holophrastic stage
About 12-18 months — expressing a whole idea with one word (such as saying 'milk' to ask for milk)
Two-word/telegraphic stage
About 18-24 months — short, grammar-free sentences of two-three words ('mummy food')
Further development
After age 2, vocabulary grows rapidly and sentences gradually become grammatically complete

Learning the mother tongue and a second language

A child naturally learns whichever language surrounds them the most as their mother tongue, even without formal teaching — this is why both the RTE Act and NCF 2005 advise prioritising the mother tongue as the medium of instruction in early classes.

Once a child has built a strong foundation in their mother tongue, learning a second or third language becomes relatively easier, because core language-acquisition skills (sound recognition, word order, meaning-making) transfer from one language to another.

Multilingualism is now seen not as an obstacle but as a resource — children who hear one language at home and another at school can become cognitively flexible with proper support, as long as neither language is discouraged.

Factors affecting language development

Positive factors — linguistic stimulation from parents and family (talking, reading books aloud), the opportunity for independent contact with peers, a rich linguistic environment.

Negative/hindering factors — multiple births (twins); research shows such children's language development is often delayed because they get less individual attention and communicate with each other in their own 'private language'. Prolonged illness, hearing difficulty and neglect also slow language development.

Early expression of emotions

Age/stageManner of expression
First few months after birthExpressing needs/emotions through crying and various sounds
LaterAdding gestures and facial expressions
Once language developsClear expression through words and sentences

REET 2024 asked how a child initially expresses emotions — the answer was through crying and sounds.

Vocabulary and sentence-structure development

After age two, a child's vocabulary grows rapidly — sometimes called a 'vocabulary spurt', in which the child starts learning several new words every day. Sentence structure also becomes progressively more complex — first two-word sentences, then three-four-word sentences, and gradually grammatically complete sentences.

During this time, children also make overgeneralization errors, such as applying regular verb-form rules to irregular words too. This is actually a positive sign, because it shows the child is trying to understand and apply the rules of language on their own, not just repeating by rote.

Language development generally follows a natural order of four skills — listening comes first, since even before birth a child begins hearing sounds in the womb; speaking follows, built on what has been heard; and only later, once oral language is reasonably established, do reading and writing develop, usually with the help of formal schooling. This order matters for teaching too — a child who is not yet a confident speaker of a language should not be pushed straight into reading and writing in that language, because the oral foundation (vocabulary, sentence patterns, pronunciation) needs to be in place first. This is one more reason NCF 2005 and the RTE Act both favour building oral fluency in the mother tongue in the earliest years before introducing formal literacy in a second language.

Using this in the classroom

SituationTeacher's role
Vocabulary is low in a younger classRepeating the names of everyday objects, showing picture books
A child finds it hard to form sentencesModelling the complete correct sentence, giving the child a chance to repeat it rather than correcting them
Twin/multiple-birth children speak less in classGiving extra one-on-one opportunities to talk and listen
A child is comfortable in the mother tongue but weak in a second languageClarifying concepts first in the mother tongue, then gradually adding words of the new language

Memory trick

Remember the 4 stages of language development in order: cooing → babbling → one-word (holophrastic) → two-word (telegraphic). And Chomsky = innate (LAD), Skinner = learnt (reinforcement) — link these two opposite theories to their names to remember them.

REET 2024 questions (solved)

Question 13

Which factor is negatively effects the learners/child’s linguistics development ?

  1. Aपरिवार की प्रकृति - एकल
  2. Bस्वायत्त रूप से साथियों से संपर्क बनाने की स्वतंत्रता
  3. Cमाता-पिता द्वारा प्रदत्त प्रेरणा की उपलब्धता
  4. Dबहुजन्म (जुड़वाँ)

Explanation

शोध बताते हैं कि जुड़वाँ या बहुजन्म वाले बच्चों में भाषा विकास प्रायः देर से होता है, क्योंकि उन्हें माता-पिता का व्यक्तिगत ध्यान कम मिलता है और वे आपस में अपनी ही भाषा में संवाद कर लेते हैं। साथियों से संपर्क की स्वतंत्रता (B) और माता-पिता द्वारा उद्दीपन/प्रेरणा (C) भाषा विकास को बढ़ाते हैं। अतः नकारात्मक प्रभाव डालने वाला कारक बहुजन्म (D) है।

Question 20

How does a child initially express emotions through language ?

  1. Aस्वर और व्यंजन के माध्यम से
  2. Bपूर्ण वाक्यों के माध्यम से
  3. Cरोने और ध्वनियों के माध्यम से
  4. Dवस्तुओं की ओर इशारा करके

Explanation

भाषा विकास के आरंभिक चरण में शिशु शब्द बोलने से पहले रोने (crying), कूकने और विभिन्न ध्वनियों के माध्यम से अपनी भावनाएँ व आवश्यकताएँ व्यक्त करता है। पूर्ण वाक्य और इशारे बाद में विकसित होते हैं।

Practice questions

Question 1

According to Chomsky, what enables a child to learn language?

  1. Aकेवल अनुकरण से
  2. Bजन्मजात भाषा-अर्जन उपकरण (LAD) से
  3. Cकेवल पुरस्कार-दंड से
  4. Dकेवल औपचारिक शिक्षण से

Explanation

According to Noam Chomsky, every child is born with an innate 'Language Acquisition Device' (LAD) that helps them learn language.

Question 2

Who is the main proponent of the behaviourist view of language development?

  1. Aचॉम्स्की
  2. Bस्किनर
  3. Cवाइगोत्स्की
  4. Dपियाजे

Explanation

B.F. Skinner is the main proponent of the behaviourist view, according to which language is learnt through imitation and reinforcement.

Question 3

What type of sound does an infant produce first?

  1. Aटेलीग्राफिक वाक्य
  2. Bकूइंग (स्वर ध्वनियाँ)
  3. Cपूर्ण वाक्य
  4. Dदो-शब्दीय वाक्य

Explanation

The first stage of language development is cooing (around 2-4 months), in which the infant produces vowel sounds, followed by babbling.

Question 4

Saying 'milk' to mean 'I want milk' is an example of which stage?

  1. Aबब्लिंग
  2. Bहोलोफ्रेस्टिक/एकल-शब्द चरण
  3. Cटेलीग्राफिक चरण
  4. Dकूइंग

Explanation

Expressing a whole idea with one word is a feature of the holophrastic/one-word stage (about 12-18 months).

Question 5

Which of the following factors negatively affects children's language development?

  1. Aमाता-पिता द्वारा नियमित बातचीत
  2. Bबहुजन्म/जुड़वाँ होना
  3. Cसाथियों से स्वतंत्र संपर्क
  4. Dसमृद्ध भाषायी वातावरण

Explanation

Research shows language development is often delayed in twin/multiple-birth children because they get less individual attention.

Question 6

What is the main point of Chomsky's 'poverty of stimulus' argument?

  1. Aबच्चों को बहुत कम भाषा-इनपुट मिलता है फिर भी वे जटिल व्याकरण-नियम सही प्रयोग कर लेते हैं
  2. Bगरीब परिवारों के बच्चे भाषा नहीं सीख पाते
  3. Cभाषा सीखने के लिए बहुत अधिक अभ्यास चाहिए
  4. Dबच्चे केवल टीवी से भाषा सीखते हैं

Explanation

This argument shows that the linguistic input children receive is inadequate and incomplete, yet they still use rules correctly, which leads Chomsky to argue for an innate ability (LAD).

Question 7

Short, ungrammatical two-to-three word sentences (like 'mommy food') are characteristic of which stage?

  1. Aकूइंग
  2. Bबब्लिंग
  3. Cटेलीग्राफिक चरण
  4. Dहोलोफ्रेस्टिक चरण

Explanation

Short, grammatically incomplete sentences of two-three words are the hallmark of the telegraphic stage (about 18-24 months).

Question 8

A teacher regularly names new objects and shows picture books to children. What is this done for?

  1. Aगणितीय कौशल बढ़ाने के लिए
  2. Bशब्द-भंडार व भाषा-विकास को बढ़ावा देने के लिए
  3. Cशारीरिक विकास के लिए
  4. Dसंवेगात्मक नियंत्रण के लिए

Explanation

Naming new objects and showing picture books provides linguistic stimulation, a strategy to boost vocabulary and language development.

Question 9

If a child makes a mistake while forming a sentence, what is the most suitable approach for the teacher?

  1. Aबच्चे को तुरंत डाँटना
  2. Bसही वाक्य बोलकर मॉडल देना और दोहराने का अवसर देना
  3. Cबच्चे को बोलने से रोकना
  4. Dगलती को अनदेखा कर आगे बढ़ जाना

Explanation

Modelling the correct sentence and giving the child a natural chance to repeat and self-correct is the most suitable teaching strategy for language development.

Question 10

What is the key difference between Chomsky's and Skinner's approaches?

  1. Aदोनों भाषा को पूर्णतः जन्मजात मानते हैं
  2. Bचॉम्स्की जन्मजात क्षमता (LAD) पर बल देते हैं, स्किनर पूर्णतः वातावरण/अनुकरण पर
  3. Cदोनों भाषा-विकास में वातावरण की भूमिका नकारते हैं
  4. Dदोनों सिद्धांत बिल्कुल समान हैं

Explanation

Chomsky holds that the capacity for language acquisition is innate (LAD), while Skinner holds that language is learnt entirely through imitation and reinforcement, i.e. from the environment.

Frequently asked questions

What is Chomsky's LAD theory?+

According to Chomsky, every child is born with an innate 'Language Acquisition Device' (LAD), which enables them to quickly learn the grammar of any language.

What are the main stages of language development?+

The general order is — cooing, babbling, one-word/holophrastic stage, and two-word/telegraphic stage.

Which factors can negatively affect children's language development?+

Multiple births (twins), neglect, hearing difficulty and inadequate linguistic stimulation can slow down language development.

What is the difference between Chomsky's and Skinner's approaches?+

Chomsky considers language an innate ability (LAD), while Skinner considers language to be learnt entirely through the environment, imitation and reinforcement.

Why is mother-tongue instruction important in early classes?+

A child is most comfortable in their mother tongue, so concepts are understood quickly and deeply in it; this foundation also later makes it easier to learn other languages.

Is learning several languages at once harmful for a child?+

No, with proper support multilingualism is a resource for a child, not an obstacle — it can increase cognitive flexibility, as long as no language is discouraged.

Why do overgeneralization errors happen, and are they a concern?+

Children try to understand grammar rules and apply them on their own, so they sometimes apply regular rules to irregular words too — this is a healthy, normal stage of language development, not a cause for concern.

When does the vocabulary spurt usually happen?+

It generally begins around age 2, when the child starts learning and using several new words every day.

In what form are language-development questions asked in REET?+

They are often asked as identifying a stage or factor, or linking a specific example to the right theory (Chomsky/Skinner/Vygotsky), not just as a direct definition.
