Bruner (AQA A-Level English Language): Revision Notes
Bruner
Overview
Jerome Bruner developed the interactionist theory, also known as the social interaction approach to child language development. This theory emphasises that whilst children possess innate abilities, these capabilities need caregiver support, social routines, and interaction to reach their full potential.
Bruner introduced the influential concept of LASS (Language Acquisition Support System), which works alongside Chomsky's LAD (Language Acquisition Device). His central argument is that language learning occurs through collaborative, social processes, shaped by structured interactions between adults and children.
Key ideas
Language Acquisition Support System (LASS)
The LASS describes the environmental structures and support systems that enable children to acquire language. Bruner argued that without these supportive frameworks, children's innate abilities cannot fully develop.
How caregivers scaffold language learning:
Caregivers provide essential support through various techniques that help children build their linguistic competence:
- Modelling - Demonstrating correct language use for the child to imitate
- Repetition - Reinforcing new words and structures through repeated exposure
- Reformulation - Restating the child's utterances in more sophisticated forms
- Questioning - Using questions to encourage verbal responses and extend thinking
- Prompting - Providing cues to help children produce language
- Shared rituals - Engaging in regular activities together (such as reading together)
These scaffolding techniques create a supportive environment where children can gradually develop more complex language skills.
Routines and formats
Everyday routines establish predictable, structured contexts where children can practise and develop their language abilities. These familiar situations provide a secure framework for interpreting language and participating in interaction.
Common examples of language-rich routines:
- Bath time, bedtime, mealtime, shopping trips
- Peekaboo games, picture book reading, nursery rhymes
What children learn through routines:
These repeated activities help children understand and internalise important communication skills:
- Turn-taking - Understanding conversational structure and when to speak
- Adjacency pairs - Recognising linked utterances (questions require answers)
- Pragmatic expectations - Learning appropriate language use in different contexts
- Discourse structure - Understanding how conversations are organised and flow
The predictability of routines gives children confidence to experiment with language, knowing what to expect and how to respond appropriately.
Joint attention
Joint attention occurs when an adult and child simultaneously focus on the same object or activity. This shared focus creates meaningful contexts for learning new vocabulary.
How joint attention works:
Practical Example: Learning through Shared Focus
When a caregiver points and says "Look! A cat!", the child learns the word within a meaningful, real-world context. This contextualised learning is far more effective than learning words in isolation.
Benefits of joint attention:
- Vocabulary development - Children acquire new words tied to concrete experiences
- Semantic mapping - Building connections between words and their meanings
- Pragmatic awareness - Understanding how language relates to the world around them
Joint attention ensures that language learning happens in context, making connections between words and their referents clear and memorable.
Scaffolding
Bruner adapted the concept of scaffolding from Vygotsky's work. Scaffolding refers to the temporary support adults provide to help children perform beyond their current independent ability level.
Scaffolding techniques:
Adults scaffold children's language development through several specific strategies:
- Giving sentence frames - Providing structures like "I want..." for children to complete
- Expanding child utterances - When a child says "car", the adult might respond "Yes, a big red car!", demonstrating more complex language
- Recasting errors in correct form - Gently correcting mistakes by modelling the proper version
- Asking guiding questions - Using questions to prompt more elaborate responses
Worked Example: Scaffolding in Action
Child says: "car"
Adult responds: "Yes, a big red car!"
This expansion demonstrates more complex language structure (adjective + adjective + noun) while validating the child's initial utterance. As children become more competent, this support is gradually withdrawn, allowing them to produce fully independent language.
The scaffolding process helps bridge the gap between what children can currently do and what they can achieve with support.
Strengths of Bruner's theory
Strong explanation of pragmatic development
Bruner's theory effectively accounts for how children acquire pragmatic skills that cannot be explained solely through innate grammar. His approach explains the development of:
- Politeness - Learning socially appropriate ways to make requests
- Turn-taking - Understanding conversational structure and timing
- Conversational repair - Recognising and fixing communication breakdowns
- Context-based meaning - Adjusting language use according to situation and audience
These pragmatic abilities depend on social interaction and experience, making Bruner's interactionist perspective particularly valuable for understanding this aspect of language development.
Empirical support
Research Evidence
Research on parent-child interactions consistently supports Bruner's claims. Studies demonstrate that:
- More responsive caregivers correlate with faster language development in their children
- Joint attention activities significantly enhance word learning
- Shared reading substantially boosts both syntactic and vocabulary development
This empirical evidence validates the importance of social interaction in language acquisition.
A balanced perspective
Bruner's theory offers a balanced view that acknowledges both biological and environmental factors. He does not reject the existence of innate abilities; rather, he argues that input and interaction unlock these capabilities. This balanced approach bridges nativist theories (like Chomsky's) and behavioural approaches (like Skinner's), providing a more comprehensive understanding of language development.
Limitations of Bruner's theory
Some cultures do not use CDS or scaffolding
Cross-cultural research reveals that not all societies employ the child-directed speech (CDS) and scaffolding techniques central to Bruner's theory. Despite this, children in these cultures still acquire language at similar developmental stages. This challenges the notion that social scaffolding is universally essential for language acquisition.
Cannot fully explain grammar acquisition
Whilst Bruner successfully explains how children use language socially, his theory does not adequately account for the acquisition of grammatical structures. Specifically, the theory struggles to explain:
Gaps in Grammatical Explanation:
- Rules of syntax - How children learn complex sentence structures
- Morphological development - How children acquire grammatical morphemes
- Overgeneralisation patterns - Why children produce forms like "runned"
These aspects of language development are better explained by nativist theories or usage-based approaches that focus on pattern recognition.
Difficult to distinguish LASS from general parenting
A practical limitation of the theory is the difficulty in isolating which specific interactions constitute LASS versus general parenting behaviours. Many caregiver behaviours overlap, making it challenging to determine which interactions specifically facilitate language learning.
Useful AO2 points for essays
Key Analytical Points for Essay Writing:
When evaluating Bruner's theory in essays, consider these analytical points:
- Bruner's LASS emphasises the importance of social routines, arguing that structured interaction enables children to develop language effectively
- Joint attention provides meaningful contexts for lexical learning, supporting the idea that interaction is central to semantic development
- Scaffolding explains how children progress from simple to more complex utterances through guided participation
- However, evidence from cultures with minimal CDS suggests that interaction is helpful but not universally necessary, challenging Bruner's claim of its centrality
Remember!
Key Points to Remember:
- LASS (Language Acquisition Support System) is Bruner's key concept - it describes the environmental support structures that help children develop language through caregiver interaction
- Social interaction is central - Bruner argues that language develops through collaborative processes, not in isolation
- Scaffolding, routines, and joint attention are the three main mechanisms through which caregivers support language development
- Strengths - The theory effectively explains pragmatic development and is supported by research evidence
- Limitations - It cannot fully explain grammar acquisition and may overstate the universal necessity of scaffolding practices
