The Process of Spoken Acquisition (AQA A-Level English Language): Revision Notes
The Process of Spoken Acquisition
Overview of language acquisition
Learning to speak is a naturally occurring but complicated journey that involves developing multiple aspects of language simultaneously. Children gradually build their abilities across lexical (vocabulary), phonetic (sound), syntactic (grammar), and semantic (meaning) structures. This process follows a generally predictable pattern, though the exact timing can vary significantly between individual children.
The journey typically begins with babbling and progresses through single words, then two-word combinations, and eventually to complex sentences. Throughout this development, children are constantly experimenting with sounds, meanings, and grammatical structures as they work towards mastering their native language.
While all children follow the same general developmental path, it's important to remember that each child's journey is unique. The stages described in this document represent typical patterns rather than rigid timelines that every child must follow.
Early sound production and exploration
The first sounds
Research has identified that the earliest sounds infants typically learn to produce are /p/, /b/, and /m/. These sounds are formed at the front of the mouth and require less complex articulatory control than other speech sounds, making them more accessible to young learners.
Birth to six months: exploration phase
During the first half-year of life, infants go through an exploratory period where they experiment with producing a wide variety of sounds. Interestingly, many of these sounds do not actually exist in their native language. This phase represents the child's vocal experimentation as they discover what their speech organs can do.
This early sound exploration is truly universal - infants from all linguistic backgrounds produce similar ranges of sounds during this phase, regardless of what language they will eventually speak.
Phonetic contraction at 12 months
Around their first birthday, infants enter a stage called phonetic contraction. During this period, children stop producing sounds that are not part of their native language. Instead, they begin to focus on and refine the specific phonetic range of the language they hear around them. This narrowing down demonstrates that children are actively tuning into the sound patterns of their linguistic environment.
Developing vocabulary and meaning
The typical progression of word types
Children's vocabulary development follows an expected order, with different word classes emerging at different stages:
Between 12 and 18 months, children predominantly learn nouns for tangible objects they can see and interact with in their environment. These concrete words form the foundation of their early vocabulary.
As children approach their second birthday, their vocabulary expands to include verbs (action words), adjectives (describing words), and prepositions (words indicating position or relationship). This expansion allows them to express increasingly complex ideas about their world.
Vocabulary Development in Action:
At 14 months, a child might say:
- "Ball" (noun)
- "Dog" (noun)
- "Milk" (noun)
By 22 months, the same child might say:
- "Throw ball" (verb + noun)
- "Big dog" (adjective + noun)
- "On table" (preposition + noun)
This progression shows how children move from naming objects to describing actions, qualities, and relationships.
Understanding before production
It's important to note that children's comprehension typically develops ahead of their production abilities. They understand far more words than they can actually say, which is why parents often notice their child responding appropriately to instructions long before they can speak clearly themselves.
Developing syntax and sentence structure
Pivot schemas and early combinations
Syntax acquisition follows a predictable pattern that linguists have identified. Children begin by using what are called pivot words alongside open class words. Pivot words are high-frequency terms that children use repeatedly in different combinations (such as more, no, or allgone), whilst open class words are the varied content words they slot in alongside them.
Children combine these two word types to create pivot schemas - basic two-word patterns like more juice or no bed. Over time, these simple pivot schemas evolve and expand, transforming into proper sentences with increasingly sophisticated grammatical structures.
Understanding Pivot Schemas:
A child learning the pivot word "more" might create combinations like:
- "More juice"
- "More cookie"
- "More play"
- "More book"
Similarly, with the pivot word "no":
- "No bed"
- "No bath"
- "No eat"
- "No go"
Notice how the pivot word stays constant while the open class word changes. This pattern forms the foundation for more complex sentence structures.
Building complexity
As children develop, they gradually extend their utterances, adding more words and grammatical elements. This progression allows them to express more nuanced meanings and complex relationships between ideas.
Theoretical perspectives on language acquisition
The nature perspective: Chomsky's Language Acquisition Device
Some researchers, most notably Noam Chomsky, argue that children possess an innate ability to learn language. Chomsky proposed the concept of a Language Acquisition Device (LAD) - a theoretical inborn mechanism that enables humans to acquire language naturally. According to this view, children have a biological predisposition for language learning that guides their development.
The nurture perspective: social interactionism
In contrast, social interactionists emphasise the crucial role of environment and interaction in language development. This perspective argues that whilst children may have some natural capacity for language, the social context and quality of linguistic input they receive are fundamental to their success in learning to talk. Through conversations and interactions with caregivers, children learn not just words and grammar, but how to use language effectively in social contexts.
An ongoing debate
These two perspectives represent different emphases in understanding language development. Whilst nativists focus on what children bring to the learning process, social interactionists highlight what the environment contributes. In reality, both innate abilities and environmental factors likely play important roles in how children learn to speak.
The nature versus nurture debate in language acquisition is not about proving one side completely right and the other wrong. Instead, it's about understanding the relative contributions of biological predisposition and environmental influence. Most contemporary linguists acknowledge that both factors work together in complex ways to enable language development.
Brown's stages of language development
Brown's Stages of Language Development provide a useful framework for understanding children's grammatical progress. This model identifies five distinct stages that demonstrate how children gradually increase their sentence length, adopt different sentence structures, and improve their grammatical accuracy.
These stages offer a practical reference point when studying language development, as they map out the typical trajectory children follow as their linguistic abilities become more sophisticated. Each stage represents a step forward in the child's ability to use language in increasingly complex and accurate ways.
Brown's stages are measured by Mean Length of Utterance (MLU) rather than age, recognizing that children develop at different rates. This approach focuses on linguistic complexity rather than chronological age, making it a more accurate tool for assessing language development.
Developing pragmatic skills
Beyond vocabulary and grammar, children must also learn the pragmatics of language - how to use language appropriately in social contexts. This includes:
- Conversation skills: learning turn-taking, staying on topic, and responding appropriately to others
- Narrative skills: developing the ability to tell coherent stories and recount events
- Politeness: understanding when and how to use polite forms and respectful language
- Appropriacy: judging what kind of language is suitable for different situations and audiences
These social dimensions of language are just as important as structural competence in becoming an effective communicator.
Pragmatic skills often take much longer to fully develop than basic vocabulary and grammar. Even when children can speak in complex sentences, they may still be learning subtle aspects of conversational turn-taking, politeness conventions, and contextual appropriateness well into their school years.
The role of input and correction
The naturalistic approach
Research shows that language development follows what is termed a Naturalistic Approach. In this model, comprehension and understanding are prioritised over explicit correction. Parents and caregivers typically do not directly correct their children's grammatical mistakes, recognising that these errors are a natural part of the learning process.
What gets corrected and what doesn't
Interestingly, whilst parents generally overlook grammatical errors, they do correct certain types of mistakes:
- Mispronunciations: Parents help children learn the correct pronunciation of words
- Factual errors: When children say something incorrect about the world (for example, calling a cow a horse), adults typically provide correction
This pattern indicates that accurate communication and correct pronunciation are seen as more immediately important than grammatical precision during early language development.
The lack of explicit grammatical correction does not mean that children learn grammar without guidance. Instead, parents naturally model correct forms through expansion and recasting. For example, when a child says "I goed to the park," a parent might respond, "Oh, you went to the park! What did you do there?" This provides the correct form without direct criticism.
Common errors and language rules
Overextension and underextension
Errors in children's early speech often reveal that they are actively working on understanding the rules of language. Two common patterns are:
- Overextension: applying a word too broadly (for example, calling all four-legged animals doggy)
- Underextension: applying a word too narrowly (for example, only using car for the family's specific vehicle, not other cars)
These errors, sometimes called overgeneralisation, demonstrate that children are not simply mimicking what they hear. Instead, they are constructing hypotheses about how language works and testing these rules in their speech. When they apply a rule too broadly or too narrowly, it shows their active engagement with the linguistic system.
Common Examples of Overextension and Underextension:
Overextension:
- Calling all men "Daddy"
- Using "doggy" for all four-legged animals (cats, horses, cows)
- Calling all round objects "ball"
- Using "shoes" for all footwear (boots, slippers, sandals)
Underextension:
- Only recognizing their own "cup" as a cup, not other drinking vessels
- Using "cat" only for the family pet, not other cats
- Calling only red apples "apple," not green ones
These patterns show children actively testing and refining their understanding of word meanings and category boundaries.
These semantic errors are actually a positive sign of language development. They demonstrate that children are not just memorizing individual words but are actively trying to understand the underlying rules and categories of language. As children receive more input and feedback, they naturally refine these overly broad or narrow categories.
Individual variation in development
Whilst the stages and patterns described above represent typical development, it's essential to remember that exact timings for each developmental milestone can vary greatly among individuals. Some children speak early, others later; some progress rapidly through stages, others more gradually. This variation is normal and does not necessarily indicate problems with language development. Each child follows their own unique timeline within the broader pattern of typical acquisition.
Individual variation in language development is the norm, not the exception. Factors such as temperament, birth order, multilingual environments, and individual learning styles all contribute to differences in timing. What matters most is that children show steady progress through the developmental stages, regardless of when they begin or how quickly they advance.
Key Points to Remember:
- Language acquisition involves developing four key areas simultaneously: vocabulary, sounds, grammar, and meaning
- Children progress from babbling through single words to complex sentences in a generally predictable sequence
- The first sounds learned are typically /p/, /b/, and /m/, with phonetic contraction occurring around 12 months
- Nouns are learned first, followed by verbs, adjectives, and prepositions as children approach age two
- The nature versus nurture debate contrasts Chomsky's Language Acquisition Device with social interactionist perspectives
- Parents naturally correct pronunciation and factual errors but typically ignore grammatical mistakes, reflecting the Naturalistic Approach
- Common errors like overextension and underextension show children actively working out language rules
- Individual variation in timing is completely normal and should be expected in language development
