Edexcel A-Level English Language: child language development, a complete overview

What this area actually demands

Child language development asks how children acquire spoken language, learn to write and learn to read, and why. Edexcel expects you to analyse child language data with accurate terminology and to apply and evaluate the theories of acquisition. The skill being tested is connecting observed features in data to recognised stages and theorists, then weighing the theories critically.

This guide covers the three sub-topics, then the exam patterns. Each has a dot-point page with practice questions; this overview ties them together.

Spoken language acquisition

Spoken language develops by level. Phonologically, children move from cooing and babbling to recognisable words, simplifying with deletion, substitution and reduplication. Lexically, the holophrastic (one-word) stage gives way to fast vocabulary growth, with overextension and underextension. Grammatically, children pass through the two-word, telegraphic and post-telegraphic stages, making virtuous errors such as "goed". Pragmatic competence (turn-taking, function) grows alongside.

Written language development

Children's writing develops through Kroll's stages: preparatory (physical skill and basic spelling), consolidation (writing like speech), differentiation (separating written from spoken forms for purpose) and integration (a controlled personal style). Spelling moves from phonetic or invented forms towards conventional orthography. Reading is taught through phonics (decoding graphemes to phonemes), the whole-word approach and the psycholinguistic approach (Goodman, Smith).

Theories of language acquisition

Four theories compete. Behaviourism (Skinner) explains acquisition through imitation and reinforcement. Nativism (Chomsky) argues for an innate Language Acquisition Device and Universal Grammar, with the poverty of the stimulus and virtuous errors as evidence. Cognitivism (Piaget) ties language to cognitive maturity. Social interactionism (Bruner and Vygotsky) stresses caregiver interaction, child-directed speech and scaffolding. Strong answers synthesise rather than back one model.

How this area is examined

A typical Edexcel profile:

• Child language data analysis. You analyse transcripts or samples of writing, identifying stages and features with accurate terminology.
• Theory application. You apply and evaluate the acquisition theories, linking features such as virtuous errors to the relevant theorists.
• Discursive evaluation. Strong answers weigh behaviourism, nativism, cognitivism and interactionism against the evidence rather than backing one.
• Accurate terminology. Marks reward correct use of terms like holophrastic, telegraphic, overextension and virtuous error.
