Language and thought: Piaget, Vygotsky, Chomsky, Skinner

A Class 2 child says, "I goed to the market and buyed two mouses." An adult might correct every word. A CTET-trained teacher notices something better: the child has worked out that English adds -ed for the past and -s for plurals, and is applying those rules everywhere. Nobody taught the child "goed". The child built it.

The CTET syllabus lists "language and thought" under Child Development and Pedagogy, and the same theorists come back in the Language Pedagogy section. Questions usually ask which theorist holds which view, how to read a child's language errors, and what a teacher should do about classroom talk and the home language.

The big question

Which comes first? There are four classic answers, and CTET expects you to match each to its theorist.

Piaget: language follows thought

For Piaget, a child can only use words for concepts they have already formed through action. The child who has not yet grasped conservation will not use "same amount" meaningfully, however often it is said.

He described the talk of young children as egocentric speech: talk that does not take the listener's view into account, such as a child narrating their play to no one in particular. In his view it fades as children become less egocentric, around the start of the concrete operational stage.

Vygotsky: language becomes a tool for thought

Vygotsky, in Thought and Language (1934), argued that in infancy there is thought without words and speech without thought, such as babbling and crying. At about two, the two lines meet.

He traced speech through three forms:

1. Social speech: talk to others, to communicate.
2. Private speech: talk aloud to oneself to guide action, most common from about three to seven.
3. Inner speech: private speech goes silent and becomes verbal thought.

Private speech rises when a task is hard. So where Piaget saw egocentric speech as a sign of immature thinking that simply disappears, Vygotsky saw the same talk as a thinking tool that goes underground. That contrast is a favourite CTET question, and the Vygotsky guide covers it in more depth.

Chomsky: an inborn capacity

Chomsky argued that children are born with a Language Acquisition Device, an innate mental capacity tuned to the structure of human language, often described through universal grammar. His evidence:

• Children everywhere acquire complex grammar quickly and at similar ages.
• They produce sentences they have never heard.
• The language they hear is limited and often broken, yet they arrive at the full grammar (the "poverty of the stimulus" argument).
• They make rule-based errors like "goed" that no adult models.

His 1959 review of Skinner's Verbal Behavior (1957) was a turning point against the purely behaviourist view.

Skinner: imitation and reinforcement

Skinner held that children learn language like any other behaviour. They imitate sounds, adults reinforce correct attempts with attention and praise, and successive approximations are shaped into adult speech. This explains vocabulary, accent and routine phrases well. It cannot explain creative sentences or overgeneralisation errors.

Bruner: the support system

Jerome Bruner accepted an inborn capacity but stressed that adults provide a Language Acquisition Support System (LASS): routines such as naming games, picture-book reading and turn-taking talk that scaffold the child's language. It is the social counterpart to Chomsky's LAD.

Does language shape how we see the world?

The Sapir–Whorf hypothesis (linguistic relativity) says the language we speak influences how we think. The strong version, that language fixes thought, is not accepted. A weaker version, that language can influence attention, memory and categories, has some support. For CTET, the safe takeaway is that language and thought influence each other.

Early language milestones

Ages vary widely between healthy children. Use these as a sequence, not a deadline.

What this means in the classroom

• Talk is learning. Let children discuss before they write, and explain their reasoning aloud.
• Treat errors as evidence. "Goed" shows a rule being learnt. Model the correct form ("Oh, you went to the market?") rather than correcting harshly.
• Ask open questions that need more than one word.
• Use the home language. The RTE Act, 2009 says the medium of instruction shall, as far as practicable, be the child's mother tongue. NEP 2020 says the home language, mother tongue or local language should be the medium of instruction at least until Grade 5, preferably till Grade 8 and beyond, wherever possible.
• Allow private speech during hard tasks.

Worked classroom questions

Scenario 1

A child says, "The sheeps runned away." The teacher should:

(a) make the child repeat the correct sentence five times
(b) recognise that the child is applying grammar rules and model the correct form naturally
(c) tell the parents the child has a language problem
(d) ignore the child's speech in future

Best answer: (b). Overgeneralisation shows active rule learning.

Scenario 2

A child solving a maze whispers, "Not this way… go up… now left." Which pair gives the two theorists' views?

Answer: Piaget would call it egocentric speech, a sign of immature thought that fades. Vygotsky would call it private speech that guides thinking and later becomes inner speech. The teacher should allow it.

Scenario 3

A child who speaks only Santhali at home joins a Hindi-medium Class 1 and stays silent. The best step is to:

(a) insist the child speak only Hindi in class
(b) allow the child to use Santhali and build bridges to Hindi through pictures, gestures and peers
(c) send the child to a lower class
(d) wait until the child learns Hindi before teaching content

Best answer: (b). The home language is a resource for thinking, and this matches the RTE and NEP position.

Practice MCQs

Q6. LASS, the support adults give to language learning, is associated with:

(a) Bruner (b) Chomsky (c) Kohlberg (d) Thorndike

Q7. A teacher asks children to discuss in pairs before writing an answer. This reflects the idea that:

(a) talk distracts from learning

(d) talk helps children build and organise thought

Answers

1. (d).
2. (b).
3. (c).
4. (a).
5. (c). No adult models those forms, so they come from the child's own rules.
6. (a).
7. (d).

What to do next

• Draw the four-theorist table from memory with one key term each.
• Write two sentences contrasting egocentric speech and private speech.
• Collect five overgeneralisation errors from children around you and name the rule each one shows.
• Read the language acquisition theories guide before your Language Pedagogy practice.
