Language acquisition (a Component 1 Section B language issues topic): the stages of children's spoken and written development, the major theories (behaviourist, nativist, cognitive, social interactionist), key evidence and concepts, and how children acquire language, argued critically with theory and examples (AO2, with AO1 and AO3).

What this dot point is asking

Language acquisition is one of the four language issues topics for the Component 1 Section B essay. It asks you to argue critically about how children acquire spoken and written language: the stages of development, the major theories (behaviourist, nativist, cognitive, social interactionist), and the evidence for and against each. This dot point covers the stages, the theories and the decisive evidence so you can write an evidenced, critical essay rather than narrating what children do at each age.

The answer

This topic succeeds when you argue critically about how children acquire language (AO2), weighing the theories against evidence drawn from real features of child language (AO1 and AO3). The unifying idea is that acquisition is a debate: no single theory fully explains how children learn language so fast and so systematically, and the strongest answers weigh the biological and the social accounts against the evidence rather than reciting one. Your task is to argue from the evidence to a position.

The stages of development

Children acquire spoken language in a predictable sequence: crying, then cooing and babbling, the holophrastic stage (single words standing for whole meanings), the two-word stage, the telegraphic stage (content words, function words omitted, as in 'daddy go work'), and the post-telegraphic stage with increasingly complete grammar. Written development follows later, from emergent mark-making and the alphabetic principle through invented spelling to conventional writing. Knowing the stages lets you read child language data and tie features to a developmental point.

The four theories

The debate runs across four positions. The behaviourist account (Skinner) holds that children learn through imitation and reinforcement (praise and correction). The nativist account (Chomsky) holds that children are born with an innate capacity, a Language Acquisition Device, evidenced by the speed and universality of acquisition, the poverty of the stimulus (children acquire more than the input could teach), and virtuous errors. The cognitive account (Piaget) holds that language develops alongside and follows cognitive development. The social interactionist account (Bruner) emphasises the role of interaction, child-directed speech and scaffolding (the Language Acquisition Support System).

Weigh the theories against evidence

The decisive skill is to argue the theories against evidence, not to recite them. Virtuous errors and the speed of acquisition tell against pure imitation; but the importance of input, child-directed speech and interaction (and evidence from cases of neglect) shows that the social account matters too. The strongest position usually recognises that acquisition is both biologically enabled and socially supported. Argue from the evidence to a critical conclusion.

Examples in context

The essay is on a set question, so the moves below are illustrative.

A model argumentative paragraph. "The behaviourist claim that children learn purely by imitation cannot account for virtuous errors. A child who says 'I goed to the park' has never heard an adult produce 'goed'; the form results from over-applying the regular past-tense rule '-ed', which the child must have internalised actively. Such errors are strong evidence for the nativist view that children construct grammatical rules rather than copying input, and they recur predictably across children, supporting the idea of an innate, rule-seeking capacity." This argues from evidence against a theory.

A model balanced conclusion. "The evidence resists a single explanation. The speed, universality and rule-governed errors of acquisition support an innate capacity, yet the role of child-directed speech and interaction, and the language deprivation seen in cases of neglect, show that input and scaffolding are also necessary. The most defensible position is that language acquisition is biologically enabled but socially supported: children are equipped to acquire language, but they do so through interaction." This weighs the accounts critically.

Try this

Q1. What is a virtuous error, and why is it important evidence? [2 marks]

• Cue. An error that over-applies a grammatical rule (such as 'goed' or 'sheeps') to a form the child has not heard; it cannot be imitation, so it supports the nativist view that children construct rules.

Q2. Name the four major theories of language acquisition and a key figure for each. [4 marks]

• Cue. Behaviourist (Skinner), nativist (Chomsky), cognitive (Piaget), social interactionist (Bruner).

Q3. Discuss the view that children acquire language mainly through imitation. [18 marks]

• What the marker wants. A critical argument (AO2) weighing the behaviourist account against the nativist and interactionist evidence (virtuous errors, poverty of the stimulus, input and scaffolding), grounded in features of child language (AO1, AO3), reaching a conclusion.
