Noam Chomsky — LAD / Universal Grammar

Theory: Chomsky argues that children possess an innate capacity for language that enables them to discover grammatical rules rather than merely imitate adult speech.

Application: Novel constructions and virtuous errors such as overregularisation can demonstrate independent rule-building and therefore support an innate linguistic capacity.

Contradiction: Innate capacity alone cannot explain acquisition because input, interaction and cognitive development also influence children’s language.

Triggers: virtuous errors • novel rules • overregularisation • rule-building • grammar • nature • innate ability

Eric Lenneberg — Critical Period Hypothesis

Theory: Lenneberg proposes that biological maturation creates a critical period during which humans are particularly equipped to acquire language.

Application: Evidence involving age together with substantially different levels of exposure or linguistic deprivation can therefore suggest maturational constraints on acquisition.

Contradiction: A child’s ordinary age alone does not demonstrate a critical-period effect because differences may instead result from exposure, interaction or individual development.

Triggers: age • deprivation • late exposure • maturation • early acquisition • critical period

Lev Vygotsky — Zone of Proximal Development

Theory: Vygotsky argues that children can perform beyond their independent ability when supported by a more knowledgeable participant within their Zone of Proximal Development.

Application: When caregiver guidance enables a child to produce or understand language they could not manage independently, this can demonstrate socially supported development.

Contradiction: Successful performance with support does not prove that social interaction alone caused acquisition because cognition and innate capacities may also contribute.

Triggers: support • guidance • scaffolding • caregiver help • assisted performance • social interaction

Jerome Bruner — Language Acquisition Support System

Theory: Bruner argues that interaction with caregivers provides a Language Acquisition Support System that facilitates children’s linguistic development.

Application: Recasts, modelling, prompts and structured interaction can therefore be analysed as caregiver support helping the child acquire language.

Contradiction: Caregiver support cannot fully explain children’s independent rule-building and novel constructions, suggesting acquisition involves more than interaction alone.

Triggers: recasts • modelling • prompts • caregiver support • interaction • routines • scaffolding

B. F. Skinner — Behaviourism

Theory: Skinner argues that language can be acquired through imitation and reinforcement as successful linguistic behaviours are encouraged and repeated.

Application: A child imitating an adult or receiving praise or another positive response for a linguistic form may demonstrate reinforcement strengthening that behaviour.

Contradiction: Children’s novel constructions and virtuous errors challenge an imitation-only account because they produce forms they are unlikely to have heard from adults.

Triggers: imitation • repetition • reinforcement • praise • correction • reward • caregiver response

M. A. K. Halliday — Functions of Language

Theory: Halliday argues that children develop language as a functional system for fulfilling different communicative and social purposes.

Application: An utterance can be classified according to the purpose it fulfils, such as instrumental requesting, regulatory control, interactional bonding or heuristic learning.

Contradiction: Communicative functions frequently overlap, so an utterance should not be forced into a single category without considering its context.

Triggers: requests • control • social interaction • feelings • questions • imagination • information • communicative purpose

Functions: instrumental • regulatory • interactional • personal • heuristic • imaginative • representational

Jean Piaget — Cognitive Theory

Theory: Piaget argues that children’s linguistic development is closely connected to their underlying cognitive and conceptual development.

Application: Increasingly sophisticated language may therefore reflect the child’s developing understanding of concepts and relationships in the world.

Contradiction: Cognitive development alone cannot account for acquisition because linguistic input and social interaction also shape children’s language.

Triggers: concepts • cognition • understanding • intellectual development • meaning • cognitive stage

Nature ↔ Nurture

Theory: The nature–nurture debate asks how far language acquisition results from innate capacities versus environmental input, interaction and experience.

Application: Evidence of independent rule-building may support nature while imitation, reinforcement, modelling and scaffolding provide evidence for nurture.

Contradiction: Acquisition is unlikely to be explained entirely by either side, so the strongest judgement weighs both according to the evidence in the transcript.

Triggers: innate ability • environment • interaction • imitation • rule-building • caregiver input • nature vs nurture

Fis Phenomenon

Theory: The Fis Phenomenon suggests that children’s perceptual knowledge of a phonological distinction can develop before their ability to produce that distinction accurately.

Application: If a child recognises an adult’s incorrect pronunciation while still being unable to produce the correct sound themselves, perception may be ahead of production.

Contradiction: A pronunciation error by itself does not prove that the child can perceive the correct contrast, so evidence of recognition is necessary.

Triggers: pronunciation • phonology • recognises correction • perception vs production • sound errors • child knows but cannot say
