Language acquisition: learned behaviour or innate? CHARLIE LEADBEATTER debates which side of the fence to sit on.

Have you ever wondered why child language acquisition (CLA) has been a hot topic amongst linguists for decades, and are we any closer in getting an answer? Is language learnt through a combination of cognitive abilities and environmental stimuli or do children have a predetermined ability to acquire language, specifically grammar? As the American linguist Bloomfield (1933, p.29) stated, the process of a child acquiring language is “doubtless, the greatest intellectual feat any of us is required to perform”.

The two main theories of CLA are nativism and social constructivism. Nativists, such as Chomsky, believe that children have a predisposed ability to acquire the grammar of any language thanks to a language acquisition device (LAD). Social constructivists such as Tomosello believe it is more of a combination between cognitive processes and environmental stimuli.

Chomsky, in critiquing the behaviourist Skinner in the late 1950s, popularised the innatist approach (nature) and coined the term Universal Grammar (UG), an inbuilt set of grammar rules which allow a child to acquire any language. Chomsky’s ‘poverty of the stimulus’ theory claims that utterances simply cannot be learned through imitation because children seem to have the ability to create an infinite number of sentences, some of which they wouldn’t have heard uttered before.

Evans (2014, pp.95-96) – a critic of Chomsky – notes that the ‘language as instinct thesis’ believes that “language, or at least Universal Grammar that underpins language, is not learned: the challenge is simply – and clearly – too great”. The task for children to acquire language without UG or an innate ability seems incomprehensible and unachievable. Nativists discredit the assumption that children acquire language via social interaction through the poverty of stimulus argument. Chomsky states that it is impossible for children to acquire language through imitation or social interaction because the input they receive is simply inadequate for something as complex as language (Chomsky, 1980, as cited by Saxton, 2017, p.217). Evidence for the LAD and UG are seen through children’s overgeneralisations. This is where children make errors by applying a generic rule to an irregular item, for example, ‘my foots hurt’. The child has applied the standard rule for plurality but for an irregular form. Another common overgeneralisation is the use of the past suffix ‘-ed’ such as, ‘I wented’ instead of ‘I went’. This seems to supports the existence of a LAD and the presence of a UG because these incorrect forms wouldn’t be learnt as no adult would utter these, so a child couldn’t possibly learn these through imitation. Also, when and if children are corrected they understand the correct form but will still produce the incorrect version.

On the other side of the coin is social constructivism, meaning in use, with which Tomasello proposed the usage-based approach. This approach focuses itself around two processes; intention reading and pattern finding. Intention reading is where children try to comprehend the intentions of adults to form some sort of linguistic communication (Tomasello, 2003, p.3). Within this framework Tomasello notes the importance of joint attention, for example, the shared attention of a third object from a caregiver. If the adult points and says “look at the truck” the child will begin to work out the intention of the utterance. If the child thinks the caregiver is wanting to bring “the truck” to his attention the child would have made the correct intention. Then when the child hears his caregiver using similar utterances with the “look at” structure he will notice the similarity and form generalisations and an understanding for that convention. Pattern finding is what the child must do in order to progress beyond the individual utterances they hear around them from adults (Tomasello, 2003, p.70). Tomasello (2003, p.70) states that “pattern finding is overall the most central cognitive construction in the usage-based approach to language acquisition”. For example, children begin to identify what sort of words are frequently grouped together, such as ‘give’ + noun, like ‘give toy’ or ‘give food’. These constructions build up schemas in the child’s mind until their grammatical ability is ‘adult-like’.

To conclude, the nature vs nurture debate has been hotly debated since the 1950s and still is in the highest academic circles, so we still are no closer in finding a definite answer and probably won’t be in another 50 years. I think the innatist approach is logical in if you believe that language is simply too complex for a child to learn through environmental stimuli. Possibly the sensible  answer would be that a combination of both approaches is responsible for how children acquire language in such a short period of time and what seems an effortless process. However I am yet to be convinced of the social constructivist approach.

Heads, language is innate. Tails, language is imitated. EMILY SILVESTER explores the outcomes of the tossed coin.

“At one time it was common to define a human as a thinking animal, but we can hardly imagine thought without words” (Barber, 1997, p.1). So how do we humans seem to effortlessly acquire language skills – including all the complexities of grammar –  which other species cannot? Imagine a never ending coin toss. Heads, language acquisition is innate – “the ability comes […] naturally” (Pinker, 1994, p.15), tails, language is learned through environmental stimuli. Toss the coin.

Heads, nature. Chomsky’s hypothesis is that the grammar of language is “genetically determined, on a par with the elements of our common nature that cause us to grow arms and legs rather than wings” (1988, p.4). Just imagine! But is grammar a universal part of our genetic makeup “determined by its biological nature” as the innatists believe? Chomsky claims that “language develops naturally and with minimal effort”, with former student Pinker pointing out that children “know things they could not have been taught” (1994, p.40-2). This innate knowledge of grammatical structures is referred to as ‘Universal Grammar’, based, for instance on the fact that children seem to know how to use inflection markers to mark tense and number, with little or no effort. My sister informs me our dog “runned in the garden” instead of “ran”. This over-generalisation with the addition of ‘–ed’, signifying past tense, is an internalised rule not imitated from the caregiver. Jean Berko Gleason conducted an experiment testing this theory in 1958, whereby the made-up word  ‘wug’ was associated with a drawing of a bird-like creature and the child was asked what they would call two of these. It found “as a fact almost any human being [will] do the task” by adding the plural marker ‘–s’, to make ‘wugs’. As the children had never heard the plural before, they had already internalized the rule and were not simply copying adults as the researchers ensured they had never heard the plural ‘wugs’ before.

Tails, nurture. Functionalists, or social constructionists, argue that communication with caregivers is essential in aiding a child’s development. Key exponent, Michael Tomasello insists “children begin to understand linguistic symbols produced by adults when they are able to participate with adults in the concept known as joint attention frames […] to understand their specific communicative intentions as expressed in an utterance” (Tomasello, 2003). So, a caregiver pointing out pictures in a book, to a child, may read: “Floppy was happy he finished his bone” or “why was Floppy happy?” The child will learn that the mother is labelling the bone, as both parent and child are looking at the dog consuming it and are both also aware that each other are looking at it. This process of ‘intention reading’ is essential. Tomasello notes that children must “come to a new understanding of their own intentional actions” (Tomasello, 1999, p.72) and be aware of “adult behaviours expressing not just simple intentions but communicative intentions” (Tomasello, 2013:296). Adopting this ‘like me’ behaviour is what a child must do “when they use linguistic conventions to achieve social ends” (Tomasello, 2012, p.69).

Another argument favouring a nurture-based theory of grammatical acquisition is a general cognitive skill that enables human infants to recognise patterns and form analyses of sounds and words. Studies have found that children have the ability to find patterns across item-based constructions by “schematizing and making analogies” (Tomasello, 2003, p.143). A child start to recognize a common pattern, for instance of ‘X liked the Y’ and learn that noun-like words will go in the X and Y slots of these ‘schema’. A sound experiment exposing six-month-old infants to a repeated combination in the left ear and an original combination in the right found, infants will lean their head to the left in favour of pseudowords they were familiar with, and that’s before they even know how to talk! This alone shows that children are a “able to recognise patterns of syllables forming ‘words’ in an auditory stream” (Evans, 2014:119).

So who is right? Is it nature or nurture? Perhaps it is a mixture of both? We don’t have a definite answer. Language theorists will no doubt continue to debate this for a long time and in the meantime children will continue to learn language, seemingly effortlessly and  “take part in one of the wonders of the natural world” (Pinker, 1994, p.15). Let’s leave the professions to toss their coins.

Universal Grammar or intention-reading & pattern-finding? EMMA BARRY explores two key theories of language learning.

There are two major contrasting approaches to child language acquisition (CLA). The ‘nativist’ approach encompasses the belief that children are born with innate knowledge of language (Universal Grammar). The opposing usage-based ‘social constructivist’ approach assumes children learn language through the input they receive from an early age (Ambridge & Lieven, 2011). These conflicting views have provoked intense debate for decades within the linguistic community. Do children have nature to thank for their ability to acquire language, or nurture?

The nativist approach was proposed in the 1950s by Noam Chomsky. Chomsky’s theory is that our understanding and knowledge of language is “part of our biological endowment, genetically determined, on par with the elements of our common nature that allow us to grow arms and legs rather than wings” (1988, p. 7). In short, we have an innate knowledge of language (mainly grammatical rules) from the day we are born.

Included in the nativist theory is the idea that all human beings are born with a set of rules – or ‘Universal Grammar’-  that can be applied to any of the world’s languages. Ambridge and Lieven (2011, p. 2) define Universal Grammar as a “formal set of rules that operate on abstract linguistic categories”. Ibbotson & Tomasello offer a simpler definition, that Universal Grammar is the idea that “children are born with the ability to make words conform to a grammatical template” (2016). For example if this theory is correct, children understand that in the phrase ‘John danced’, the noun ‘John’ must appear before the verb ‘danced’ is evidence of the innate rules performing a syntactic operation (creating a grammatically correct phrase) (Ambridge & Lieven, 2011, p. 3).

The nativist approach is backed up by Chomsky’s claim of a ‘poverty of stimulus’. The poverty of stimulus idea is that “the linguistic environment is too impoverished for a child learner to achieve full adult competence” (Reali & Christiansen, 2004). In short children can generally produce sentences they haven’t been exposed to before (Toppleberg, Collins & Martin, 2004). In the eyes of the nativists, this supports their views and the argument for nature over nurture as it implies that there must be a faculty inside a child’s brain allowing them to create and produce utterances previously unheard.

However, none of the data used in the nativist theory is empirical, meaning that none of the examples used in support of this theory are based on real evidence. This is because Chomsky believes that the number of performance errors means it is impossible to gain an accurate representation of a person’s grammatical competence based on recorded data. But does this compromise the validity of his theories?

The social constructivists hold an opposing view claiming that the only innate knowledge children possess is the ability to learn language because of other more general cognitive skills rather than any inbuilt rules of grammar. This approach analyses empirical data from “actual communicative events” (Ibbotson & Tomasello, 2016). They believe that children use ‘intention reading’ and ‘pattern finding’ to generalise from examples to understand language and create new utterances, refuting the nativist’s poverty of stimulus theory.

Michael Tomasello, the main driving force behind the social constructivist approach, explains that “a child must work out the intentions of the mature speaker to achieve social ends” and they do this through a process called ‘intention reading’. Ibbotson & Tomasello (2016) give the example of the question “can you open the door for me?”. In this situation the child must work out that the question is a request for help not a request into their door opening abilities.  ‘Pattern finding’ works alongside ‘intention reading’ in the constructivist approach. ‘Pattern finding’ involves the realisation of patterns in language from the child to create linguistic schemas and constructions. For example, in English a child should come to realise the pattern of noun-verb-noun in utterances such as “Jane kicks the ball” and be able to generalise this pattern into their own speech (Rowland, 2014, p.100). Ibbotson and Tomasello (2016) use the sentences “the dog wants the ball” and “the dog wants food” as an example for pattern finding with the idea that after hearing this similar structure time after time the child will be able to adopt the framework and create their own novel sentences, such as, “the dog wants the bowl”.

In short, on one hand we have the rather convincing innateness theory proposed by nativists, with the poverty of stimulus argument there to deter any doubt. On the other hand there is the social constructivist theory, all based on concrete evidence. So, nature or nurture, or maybe even a little bit of both, where do you stand?

How do children really acquire language? Is it in their nature or do they need to be nurtured along the way? KATIE ROBERTS investigates.

Do you have a burning desire to know how you started talking and forming grammatical sentences? This may not be at the top of your priority list but there has been a debate in this linguistic field for decades.  Are we any closer to an answer?

One viewpoint that has been very popular since the early 1960s is the ‘innatist’ approach to child language acquisition. Noam Chomsky is most closely associated with this. As the term suggests, innatists believe our ability to learn and use language is innate and “encoded in our genes” (Rowland, 2014, p. 15). This seems rational because children appear to learn language very rapidly. Pinker (1994) even refers to them as “lexical vacuum cleaners” (p. 151). He claims that language is a manifestation of a natural pre-wired “Language Instinct” (Pinker, 1994) which is triggered when a child is exposed to language output.

This builds on Chomsky’s proposition that humans have an innate grammatical capability, based on Universal Grammar (UG). Essentially, UG is the “properties of language that are mentally represented by an internal linguistic system (a grammar)” (White, 2003, p. 2). Where is the support for this? Consider the input that children receive around them. Is it a perfect model to emulate and learn from? The answer, according to Chomsky is ‘no’. Natural spoken language is full of performance errors, false starts, hesitations and fillers like “err”. Chomsky called this the ‘Poverty of Stimulus’. Our experience cannot account for our ability to generate novel sentences and so innateness must accountable for the resulting production of language (Lasnik & Lidz, 2017, p. 1).

This is admittedly a captivating attempt to explain child language acquisition. But can this be tested and proven empirically? Akhtar claims there is no way of providing watertight evidence to support this so-called ‘nature’ (as opposed to ‘nurture’) approach to language learning (2004, p. 460). So is the concept of Universal Grammar just a “Language Myth” (Evans, 2014)?  Your guess is as good as mine.

Critics of innatism propose an alternative explanation for the way children learn to speak, often called ‘Social Constructivism’. Michael Tomasello is the theorist often associated with this. Social constructivists believe that children have a natural intuition and certain cognitive abilities that help with the acquisition of language but the focus is shifted to “meaning in use” (Tomasello, 2012, p. 69). In sunning theories of innate mechanisms and language modules in the brain (Evans, 2014, pp. 96- 7) children are believed to develop language skills as a result of social and cultural environments – a desire to communicate. If anything, it serves a purpose for them.

The notion of an inbuilt pre-existing mechanism is discarded in a usage-based focus. Instead, function in use is the driving force for acquisition. Two skill sets form the fundamental components of this approach – ‘intention-reading’ and ‘pattern-finding’.

These two terms are best taken as a bottom-up interpretation, whereby grammatical “categories and rules [for language] are built up gradually” (Rowland, 2014, p. 96). Rather than being inborn, basic categories and acquisition of language are “facilitated by parents, peers, teachers, and others” (Kaufman, 2004, p. 304). Constructivists rely heavily on the notion of caregiver assistance and the input from others (‘nurture’). This might be right; language after all is a social phenomenon.

It is undoubtedly important for a child to “work out what message a speaker intends to convey” (Rowland, 2014, p. 101). Ibbotston and Tomasello provide an example from a recent article in the Scientific American. In an utterance such as “can you open the door for me?” (2016), a child would need to follow the attention of the speaker – i.e. intention reading – and realize that this is a request, understanding specified interactive goals. The next level moves from this functional base and progresses to the grammatical dimension – ‘pattern-finding’. A child needs to move “beyond individual utterances they hear people using […] and create abstract linguistic schemas” (Tomasello, 2012, p. 70). The example of “want + desired object” (Rowland, 2014, p. 101) illustrates this, for instance ‘I want drink’ or ‘I want ball’ from an ‘I want X’ pattern. Basic schemas can assist with language and sentence development. Social constructivists think children use these to slot new words into a frame.

So, does one approach have more value than the other? Many academics have latched onto one theory and have only “discussed research conducted within the relevant paradigm of interest” (Ambridge & Lieven, 2011, p. 13). There is a danger that scholars cherry-pick examples to suit their pre-existing ideas. The so-called ‘nature versus nurture’ debate is likely to continue for now. At the end of the day we can’t ask a baby how it learns to speak!

Nature, nurture and a gene. What does it all mean? NATHAN DURRINGTON is foxed by language acquisition

It is the only concept on earth that we have to use for it to be talked about. The concept of language without any great deal of thought is simply just another one of those human phenomena many of us take for granted. Despite large amounts of research being conducted into the debate, we are yet to find an undisputed answer to how we acquire language. In recent years, leading linguists, Noam Chomsky and Michael Tomasello, among others, have argued whether nature or nurture is responsible, whether a device in our brain exists or whether we rely totally upon input from our parents and caregivers, but is it finally time for the debate to be revolutionised? I’d probably say so.

The first notable scientific approach came in the shape of Skinner (1957) who coined the idea that the acquisition of language was a feature of behaviourism. Imagine this scenario: “the child says ‘milk’ and the mother will smile and will give [the child] some. As a result, the child will find this outcome rewarding, enhancing the child’s language development” (Ambridge & Lieven, 2011). However, Chomsky criticised Skinner’s theory on the basis of there being a ‘poverty of the stimulus’, suggesting there are too many complex grammatical rules for a child to learn, relying upon language input alone (Chomsky, 1976) and with that the behaviourist approach was somewhat (correctly) disregarded.

Taking pole position now, was Chomsky himself. Through his nativist approach, he stated, “aspects of our knowledge and understanding are innate, part of our biological endowment, genetically determined, on a par with the elements of our common nature that causes us to grow arms and legs rather than wings” (Chomsky, 1988, p.4).  Two key elements that Chomsky preached within his ideology are, the ‘poverty of stimulus’ and ‘universal grammar’, the latter which “may be thought of as some system of principles, common to the species and available to each individual, prior to experience” (Chomsky, 1981, p.7).

Then came along the social constructivist, Michael Tomasello. He somewhat dismissed Chomsky’s claims on the basis of him being an ‘armchair linguist’. He instead promoted Wittgenstein’s ‘meaning is use’ approach (1953). This approach is comprised of two elements. The first suggests that children must “come to a new understanding of their own intentional actions… [Following this, they must] use their ‘like me’ stance to understand the behaviour of other persons in this same way” (Tomasello 1999, p.72). This concept, known as ‘intention reading’ is “what children must do to discern the goals or intentions of mature speakers when they use linguistic conventions to achieve social ends” (Tomasello, 2012, p.69). The second element is ‘pattern finding’. This is “what children must do to go productively beyond the individual utterances they hear people using around them” (Tomasello, 2012, p.70). When these two features work in unison, children will “understand the communicative functions of utterances… [They do this] by reading the intentions of the speaker. They then find patterns across item-based constructions by schematizing and making analogies” (Tomasello 2003, p.143). With this we have the point of view of the nurture side of the debate.

Still with no clear answer as to how we acquire language, is it time we look elsewhere? Since the turn of the millennium, considerable work has gone into investigating the FOXP2 gene. The gene is found to “influence the development of the nervous system, and parts of the brain involved in motor skills” (Kunert, Jongman & Prins, 2013, p.2) suggesting that the gene is pivotal to evolving the muscle structure required for such complex articulation. It is also found that “individuals that have a mutation of the FOXP2 gene suffer from speech and language disorders, and have difficulties expressing and articulating language” (Kunert, Jongman & Prins, 2013, p.2). This area of research has been reinforced with evidence, which would suggest that it has strong foundations.

With the argument concerning genes still being in its infancy, it is impossible to hypothesise that it is responsible for language learning just yet. However it is key that its potential is not ignored. Despite this, when we consider the evidence we do have, it may be sensible to change the way we look at the debate, is it really a case of one being more important than the other? Or we should we be asking “to what extent do nature and nurture combine to allow the acquisition of language?”

Internal or innate, the great language acquisition debate. LUCY HANCOCK investigates

Will there ever be an end to the controversy about how children manage to acquire language seemingly so easily? According to Cacioppo & Freberg (2013), Francis Galton was the first to coin the phrase ‘nature versus nurture’. He was very much in support of the ‘nature’ hypothesis, claiming “I propose to show […] that a man’s natural abilities are derived by inheritance” (Galton, 1869, p. 1).  This bold statement has been supported heavily by Chomsky, one of the most respected linguists, renowned for his theory that language structure is biologically determined in the human mind. In stark contrast stood the behaviourists whose belief in the acquisition of language through imitation of adult language and positive reinforcement (or conditioning) to encourage repetition of accurate linguistic constructions, was severely criticised by Chomsky in the late 1950s. Skinner (1957, p. 199) stated that “among the sounds which become important are the verbal responses of his parents and others. The child can then reinforce himself automatically for the execution of vocal patterns which are later to become part of his verbal behaviour.” The behaviourists were very much interested in the influence of a child’s environment upon their acquisition of language, a factor that the nativists like Chomsky chose to ignore.

According to Stilwell Peccei (2006, p. 3), “Chomsky proposed that children actively construct the rule systems of their native language aided by a brain already pre-wired with a special language capacity”. This apparent innate set of language rules, that are present in every human brain from birth, was labelled ‘Universal Grammar’ and nativists believe this inbuilt device is the key to a child’s language acquisition. They argue that a child’s environmental exposure to language is simply not enough for them to acquire a complete linguistic system. This so-called ‘poverty of stimulus’ is the idea “that the knowledge acquired in language acquisition far outstrips the information that is available in the environment” (Laurence and Margolis 2001, p. 221). Despite the amount of interest and support for the nativist theory, there is little empirical evidence to validate it (Akhtar, 2004). The legitimacy of this argument is called into question due to the theoretical nature and the lack of data to prove the proposed theories. On the other hand, it would be difficult, if not impossible, to study the human brain from the moment of birth to search for the supposed ‘Language Acquisition Device’, the area of the brain in which nativists believe language ‘lives’.

In juxtaposition to the nativist argument, we have the constructivists who, as stated by Lieven and Brandt, are named as such “because children are seen as building up an inventory of constructions” (2014, p. 282). They believe in the idea of language acquisition via exposure to rich language; once the exposure to adult language has occurred, the child will imitate this. It is claimed that language is the product of life experiences and that the human brain is powerful enough to learn, memorise and retain information simply through exposure. Tomasello, one of the leading constructivists in this approach, focuses his thinking around the idea that “children begin to acquire language when they do because the learning process depends crucially on the more fundamental skills of joint attention, intention-reading and cultural learning” (2003, p. 21). A child must understand the communicative intentions of an adult or caregiver and share joint attention to the object the caregiver is referring to. Once this joint attention is achieved, the child should then, according to this theory, be able to imitate the adult’s constructions.

It seems that both sides of this debate have little chance of working alone to explain the process of language acquisition. Should we believe that language is innate from birth? Or is it more a process of learning from our environment? Instead of separating the debate into two sides, would it not make more sense to combine them and see how well they work as one?

Acquiring language: inbuilt or learnt? ALICE LEATHER explores two competing theories

Have you ever wondered what gave you the urge to start talking? Do you know why you began to order words in the correct grammatical pattern? These are questions that have baffled linguists for many years and has led to what is often labelled the ‘nature versus nurture debate’ of language acquisition. Nunan (2013) states that the acquisition of language children is often described as miraculous. By the age of four most children have their first language pretty well acquired and know over ten thousand words (Nunan, p. 127). But how do they get to this point? Are children born with language or does it take time and experiences for them to learn? Two opposing theorists in this debate are Noam Chomsky and Michael Tomasello.

Chomsky developed the mentalist approach to language acquisition which underpins the nature side of the debate. Chomsky (1988, p. 4) states “certain aspects of our knowledge and understanding are innate, part of our biological endowment, genetically determined […]”. In other words he believes that language is hard wired into the human brain and to acquire it all you need to do is to be born human and be exposed to it. He named this innate knowledge ‘universal grammar’ which is said to “contain a set of grammatical principles that are shared by all languages universally” (Rowland, 2014, p. 235).  Pinker (1994, p. 18), one of Chomsky’s former students, also describes language as an ‘instinct’ because language develops in a child spontaneously, without conscious effort or instruction. This reinforces the idea that mentalists believe language is a distinct piece of biological makeup of the brain and therefore it is their only explanation needed for the acquisition of language.

Although many aspects of Chomsky’s theory are compelling, there are holes in the argument. Linguists like Sampson believes that mentalists make claims about language universals and base it on only one example, without using further examples or evidence (Sampson, 2005, p. 138). This suggests the mentalist theory relates only to a subjective view and has no scientific proof. Nunan (2013) states that “input to babies is a lot less ‘junky’ than may be imagined”. He explains that when adults talk to babies they do so slowly, enunciate more and speak in proper sentences. Parents direct their children to aspects of language by correcting and repeating things which disagrees with the mentalist approach (p. 131). Nunan (2013, p. 132) also discusses that children suffer from limits on their communicative competence, meaning they have something to say but do not have the linguistic means to do so. This can be a source of frustration but also a powerful stimulus for acquisition that is not explained by the mentalist theory.

If there are flaws to Chomsky’s theory and the nature debate then what is the alternative? Are there other ways we learn language?

Social constructivist, Tomasello, promotes the nurture side of the debate by taking more of a functionalist view on acquisition. Tomasello (2005) dismisses the idea that children are born with an innate knowledge of grammar and argues that children acquire language by firstly understanding how others around them use it (p. 4). He developed the usage-based approach, which is perhaps one of the most modern approaches to language acquisition. According to this theory, learning constructions and their meanings can be accomplished using general cognitive and social abilities. At around the age of one children come to acquire language equipped with two sets of skills which are ‘intention reading’ and ‘pattern finding’ (Rowland, 2014, p. 100). Tomasello (2012, p. 69) claims “[i]ntention reading is what children must do to understand the goals of people around them when they speak”.

“Pattern-finding is what children must do to go productively beyond the individual utterances they hear people using around them to create abstract linguistic schemas” (Tomasello, 2012, p. 70). These skills are key in the functionalist approach in order to explain how we participate in a successful conversation.

There really is no concrete conclusion to this on-going debate and I believe this is because it is unethical to conduct experiments on new born babies’ brains in order to provide substantial scientific evidence on how language is acquired. We must have some form of innate knowledge in order to explain why we can begin to speak at such a young age, however, it cannot be the only answer. Functionalism must also play its part because input seems crucial to a child’s language development. We need to be exposed to language in order to find use for it and through teaching we can expand our vocabulary. Will the followers of Tomasello and Chomsky eventually join forces and reach a conclusion?  The battle continues…
