Tomasello (AQA A-Level English Language): Revision Notes
Tomasello
Overview of Tomasello's approach
Michael Tomasello developed the usage-based theory of language acquisition, also referred to as the cognitive-functional approach. This theory emerged in the 1990s and continues to influence contemporary linguistic research.
Tomasello's work represents a significant shift in how researchers understand language acquisition, moving away from the idea that grammar is innate and instead emphasizing the role of general cognitive abilities and social interaction.
Tomasello's work directly challenges two major theories of language development:
- Chomsky's nativism: the idea that grammar is innate and hardwired into the brain
- Behaviourism: the view that language is learned purely through imitation and reinforcement
Instead, Tomasello proposes that language emerges from children's broader cognitive abilities, particularly their capacity for shared intentionality. This means children learn language not through a special inborn grammar device, but through general thinking skills that help them collaborate, understand others' intentions, and recognise patterns in the language they hear around them.
His theory emphasises that children acquire grammar by using language in real communicative situations. They notice patterns in speech, gradually building more sophisticated linguistic structures over time. This approach has strong empirical backing and is highly valued in AO2 evaluation for A-Level English Language.
Key ideas in Tomasello's theory
1. Shared intentionality
Shared intentionality is central to Tomasello's explanation of how language develops. He argues that humans possess unique abilities to collaborate with others, understand their intentions, and work towards shared goals. These social-cognitive skills create the foundation upon which language is built.
From approximately 9-12 months of age, infants demonstrate several key behaviours that show shared intentionality:
- Joint attention: focusing on the same object or event as another person
- Pointing to share information: gesturing to direct someone else's attention
- Following gaze: tracking where another person is looking
- Understanding intentions: recognising what others mean to communicate
These early social-cognitive abilities are crucial because they enable children to work out what speakers mean when they use language. Before children can learn words and grammar, they need to understand that communication involves shared understanding between people. This social awareness forms the foundation for learning language.
Practical Example: Shared Intentionality in Action
Imagine a 10-month-old infant and their parent looking at a picture book together:
- The parent points to a picture of a dog and says "Look, doggy!"
- The infant follows the parent's gaze and pointing gesture
- The infant focuses on the same picture (joint attention)
- The infant might point back at the dog or make sounds
- Through this shared focus, the infant begins to associate the word "doggy" with the animal
This interaction demonstrates how shared intentionality creates the conditions for language learning - the infant isn't just hearing a word, they're understanding that the parent intends to share information about a specific object.
2. Language as a set of constructions (construction grammar)
Tomasello firmly rejects the concept of an innate Language Acquisition Device (LAD). Instead, he proposes that children learn constructions - pairings of linguistic form and meaning that work together as units.
A construction can be as simple as a single word or as complex as a full sentence pattern. What matters is that form and function are learned together.
Examples of Constructions at Different Levels
- More juice? functions as a request construction
- Where's X? functions as an information-seeking construction
- I'm X-ing it represents an emerging transitive construction
Young children initially learn these as complete, unanalyzed chunks. A child might say "Where's Daddy?" as a single formulaic unit without understanding it consists of separate words "where," "is," and "Daddy."
Young children initially learn these as holistic expressions - formulaic chunks that they use as complete units. They do not break them down into individual words or grammatical parts at first. Only later do children analyse these expressions and extract underlying patterns.
This contrasts sharply with nativist theories, which claim children are born with abstract grammatical rules already in place. Tomasello argues that abstraction comes later, after children have accumulated many concrete examples of language use.
3. Pattern-finding and intention-reading
Tomasello identifies two fundamental cognitive abilities that drive language development:
a) Intention-reading
Children work out what adults mean by their utterances through several processes:
- Interpreting gestures: understanding pointing, facial expressions, and body language
- Following attention: noticing what the speaker is focused on
- Understanding communicative goals: recognising whether someone is requesting, commenting, or questioning
- Recognising pragmatic intent: grasping the speaker's purpose in context
Crucially, Tomasello argues that language is learned through meaningful usage, not through learning abstract rules in isolation. Children understand language as a tool for achieving communicative purposes.
b) Pattern-finding
As children experience many different utterances, they naturally detect patterns across them. This cognitive ability to spot regularities leads to:
- Categorisation: grouping words into types like nouns, verbs, and adjectives
- Schema formation: creating mental templates for how language works
- Grammar building from repeated structures: extracting rules from frequently heard patterns
Grammar emerges gradually as children notice regularities across the language they hear. The more frequently a pattern occurs in the input, the more likely children are to extract and use it themselves. This explains why high-frequency structures are typically acquired before low-frequency ones.
4. No universal grammar / No LAD
Tomasello explicitly rejects several key claims of Chomskyan linguistics:
- Innate grammatical mechanisms: the idea that children are born with grammar already programmed
- An inborn universal structure: the notion of underlying rules common to all languages
- The poverty of stimulus argument: Chomsky's claim that input is too limited for children to learn language without innate knowledge
Instead, Tomasello proposes that children rely on domain-general learning skills - cognitive abilities that apply to many areas of learning, not just language. These include problem-solving, categorisation, and intention-reading. Children use these general cognitive tools to acquire language.
His position is clear: grammar is learned from use, not pre-installed in the brain. Children build linguistic knowledge incrementally by engaging with language in social contexts.
5. Slow, bottom-up acquisition of grammar
According to Tomasello, children's grammar develops slowly because they construct it incrementally - building it up piece by piece from concrete examples.
The acquisition process follows distinct stages:
1. Holophrases: single words or fixed phrases used as complete utterances (e.g., allgone, wassat)
2. Pivot schemas: simple frames with one fixed word and one variable slot (e.g., more X, X gone)
3. Item-based constructions: verb-specific frames that children learn for particular words (e.g., I want X, Let's go X)
4. Abstract constructions: generalised grammatical patterns that work across many different words (e.g., subject-verb-object structure)
This gradual progression from concrete to abstract stands in sharp contrast to Chomsky's theory, which suggests children have early access to innate, abstract grammar. For Tomasello, abstraction is the endpoint of development, not the starting point.
Strengths of Tomasello's theory
1. Strong empirical support
Research evidence consistently backs up Tomasello's predictions:
- Studies demonstrate that children rely heavily on input frequency - they acquire structures they hear most often first
- Grammatical development mirrors usage patterns in the language around children
- Children's early utterances follow item-based frames, just as Tomasello describes
- Research shows that children's pointing and joint intentionality predict language outcomes - those who engage in more shared attention activities develop language more successfully
This empirical foundation makes the theory scientifically robust and particularly valuable for high-band AO2 evaluation. You can cite specific research findings to support Tomasello's claims when comparing different theories.
2. Explains pragmatics and social cognition
Unlike nativist theories, which struggle to account for how children learn to use language appropriately, Tomasello's approach effectively explains:
- Context-based meaning: how children understand that the same words can mean different things in different situations
- Intention-reading: how children work out what speakers really mean beyond literal words
- How children learn communicative functions: understanding that language can request, inform, promise, apologise, etc.
- Why interaction accelerates acquisition: social engagement speeds up learning because it provides meaningful contexts for language use
This makes Tomasello's theory particularly strong for explaining the pragmatic and social dimensions of language development.
3. Accounts for gradual grammar development
Tomasello's model successfully explains several observed features of child language:
- Slow acquisition of syntax: why grammatical development takes years rather than happening suddenly
- Broad variation across languages: why children learning different languages show different developmental patterns
- Emerging complexity based on input: why children's grammatical sophistication grows in line with the language they experience
These aspects align well with what researchers actually observe in children's speech.
4. Bridges cognitive and social theories
Tomasello's approach is notably holistic, bringing together multiple factors:
- Cognitive skills: pattern-finding, categorisation, and problem-solving abilities
- Social interaction: the importance of communication and collaboration with others
- Usage frequency: the role of exposure to language in real contexts
- Construction-based grammar: a new way of understanding grammatical knowledge
This integrated approach makes the theory modern and comprehensive, incorporating insights from both cognitive psychology and social interaction theories. It represents a move away from seeing language as an isolated mental faculty.
Limitations of Tomasello's theory
1. Does not fully explain universal stages
Although Tomasello emphasises that development is usage-based and dependent on input, children worldwide display remarkably similar broad stages of development. This universality might suggest some innate tendencies exist, which challenges a purely usage-based explanation.
Critics argue that if language were entirely learned from exposure, we would expect much greater variation in developmental sequences across different linguistic environments. The fact that children in vastly different cultures show similar patterns suggests something more than just learning from input.
2. Pattern-finding alone may not explain complexity
Some linguistic structures appear particularly challenging to explain through pattern-finding alone. Complex grammatical features such as:
- Recursion: embedding clauses within clauses (e.g., The cat that chased the mouse that ate the cheese ran away)
- Embedded clauses: structures like I think that she knows that he left
These sophisticated structures seem difficult to acquire purely from exposure to examples. Critics question whether pattern-finding provides sufficient explanation for how children master such complexity, especially since recursive structures may appear relatively infrequently in child-directed speech.
3. Less emphasis on biological predispositions
Some critics argue that Tomasello downplays biological factors too much. Evidence suggests humans may be biologically specialised for language in ways that go beyond general cognitive abilities. For instance:
- Humans show remarkable consistency in language learning across diverse environments
- Certain brain areas (like Broca's and Wernicke's areas) appear specialised for language
- Children acquire language far more successfully than other primates, even when primates receive extensive training
By emphasising social and cognitive factors, Tomasello may underestimate the role of evolved biological capacities specific to language. This doesn't necessarily invalidate his theory, but it suggests the picture might be more complex than a purely usage-based account allows.
4. Slow acquisition conflicts with some early abilities
Research demonstrates that infants display sensitivity to grammar-like patterns remarkably early - even before they have had extensive language usage experience. This early sensitivity appears to challenge Tomasello's strictly bottom-up model.
For example, very young babies can distinguish grammatical from ungrammatical sequences in artificial languages, suggesting some readiness for grammatical structure may exist prior to extended exposure. This poses a challenge to the view that all grammatical knowledge is built up slowly from concrete examples.
Using Tomasello in AO2 evaluation
When writing exam essays, consider these key points for high-band AO2:
Evaluation Framework for Exam Writing
-
Tomasello proposes that children learn language through general cognitive skills, particularly pattern-finding and intention-reading, rather than through innate grammatical knowledge
-
The usage-based approach successfully explains early formulaic expressions and the gradual emergence of grammar, showing how linguistic complexity develops over time
-
Shared intentionality provides a compelling explanation for pragmatic and communicative development, addressing areas where nativist theories are weaker
-
However, the theory faces challenges in explaining universal stages of grammatical acquisition and may not fully account for potential biological mechanisms emphasised by the nativist model
These points work excellently when comparing modern cognitive-linguistic theory with Chomsky - showing you understand different theoretical perspectives and can evaluate them critically.
Key Points to Remember:
-
Tomasello's usage-based theory argues that language emerges from social interaction, cognitive skills, and pattern detection - not from innate grammar.
-
Shared intentionality (the ability to collaborate and read others' intentions) forms the foundation for language learning from around 9-12 months.
-
Children learn constructions (form-meaning pairings) gradually, progressing from holistic phrases through item-based frames to abstract grammatical patterns.
-
The theory has strong empirical support and effectively explains pragmatic development and gradual grammar acquisition.
-
Key limitations include difficulty explaining universal developmental stages, complex grammatical structures, and early grammatical sensitivity in infants.
