Development of Human Language, Neurolinguistics and Psycholinguistics: Exmaining Studies on Feral and Isolated Children

All Human beings are born with a basic fundamental knowledge of the language and this progresses throughout their lifespan. Developmental psychologists research the developmental trajectory as this shows how the language, reasoning and social skill abilities develop.

There are 4 theoretical perspectives. The different theoretical perspectives vary in their focus on the role of nature and nurture as well as the emphasis on one or more of the five aspects of language knowledge. Throughout this chapter, the focus will be on recognizing how nature and nurture interact and can be related. It provides a framework for understanding the complex ways children develop language as they interact with people and objects in their environment, school and home

On the other hand Nativists believe that language acquisition is a biological occurrence. Their theories confirm that important aspects of children’s linguistic knowledge are not acquired, but innate (Ambridge B, 2011). Their theories emphasise the structure of the human brain and how it obtains and uses language. Social Critic Noam Chomsky proposed that children are born with the ability to generate grammar (Dulay, H. 1982). This emphasises nativist’s theories and promotes nature to be the dominant role.

Nature and nurture both play a significant role in language development. Language development refers to how children understand, organise, speak and use words in order to communicate at an effective, age-appropriate level (Karen Kearns, 2013, P.105). For centuries, theorists have been debating the roles of nature versus nurture. Although, each child’s language will develop at their own pace and there will be many individual differences based on culture, ethnicity, health and ability. As well as physical, social, emotional and cognitive development in which will contribute to a child’s language development.

First, children¡¯s acquisition of language is an innate mechanism that enables a child to analyze language and extract the basic rules of grammar, granted by Chomsky. It basically states that humans are born with a language acquisition device that, the ability to learn a language rapidly as children. However, there is one important controversy in language acquisition concerns how we acquire language; since Chomsky fails to adequately explain individual differences. From the behaviorists¡¯ perspectives, the language is learned like other learned behaviors. It is learned through operant

Young people and children are affected by wide variety of personal and external factors in their development and are conditioned by variants such as family environment and education establishments.

In this task I am going to identify 2 different theories of language development I am going to be doing, Naom Chomsky and Jean Piaget.

The case of “Genie” is a tragic look at the effects of child abuse and neglect on childhood development. Genie’s case was particularly extreme, as she lived the first 13 years of her life in isolation and confinement. With little to no human interaction throughout her entire life, she developed no language skills. Researchers were extremely interested in this case, as it gave them a chance to explore two theories of language development. One theory is Noam Chomsky’s view that children are born with an innate ability to learn and understand language. Chomsky termed this structure in our brain the “Language Acquisition Device” (LAD). An alternate theory by Eric Lenneberg stated that language development is a result of our environment, and stressed the importance of critical periods. Lenneberg believed that the critical period for language development only lasted until around 12 years of age, and inability to develop language during these critical periods would result in major deficits.

In the documentary, “Secret of the Wild Child,” it reveals the important case of Genie, a young girl who suffered severe abuse and was deprived of linguistic stimulation. She was discovered by a case worker at the age of 13 and was noted to be extremely underdeveloped for her age. Once physicians and psychologists discovered she had not been able to learn a language, research underwent to test whether or not there is a critical period for language acquisition. However, ethical and moral issues arose of how the psychologists treated her, claiming they were using her as a test subject for experimental results and not treating her as a human being. Regardless of the endless disputes, Genie’s case has benefited the world of psychology in understanding human development.

However, it can be argued with (Bruner 1964) that social interaction doesn’t explain all the complexities of language acquisition. Almost every day the language we hear is often incorrect, poorly defined, incomplete and full of hesitations, mispronunciations and other errors, and yet despite this we still learn to talk following the correct grammatical rules. Again this indicates the idea of Chomsky’s (1968) LAD model that children are born ‘hard-wired’ with the innate knowledge of linguistic rules and so these rules help the baby make estimations and presumptions about the language it is hearing. From these estimations and presumption the child can work out grammatical sets of rules and when more language is exposed to them, the more their language develops. Even within Chomsky’s (1968) LAD theory, undoubtedly he believed the role and promotion of the ‘nature’ aspect is the core foundation on which language can develop. But his theory also requires the role of nurture

Rough-and-tumble play is common in school recesses, where children are developing cognitively. If a child has been to preschool before, chances are, they’ll be ahead of the curve a bit when learning to solve problems, and learning how to read and write. This is another major way in which nurture has its effects on a child’s outcome in development. If a child has received enough attention, and has been read to, then they are perfectly ready to solve problems rationally, in an organized way.

There are several theories regarding language development. Work by Chomsky, Piaget and Kuhl are critical. Studies by Chomsky, as examined by Albery, Chandler, Field, Jones, Messer, Moore and Sterling (2009); Deloache, Eisenberg & Siegler (2003) argued for the innateness of language acquisition due to its complexity. Development is assisted by a language acquisition device (LAD) and universal grammar both of which holding the propensity for commonalities throughout all languages. LAD is the key to the Syntax rule. The knowledge to master the rules is held unconsciously. Chomsky concludes exposure through auditory channels as being the only requirement for learning. Arguably Kuhl (2010) writes infantile exposure to language through auditory channels only, does not contribute effectively to learning indicating the importance of human interaction. Piaget, as discussed by Ault (1977) postulated language as not being part of the earliest stages of development. Signifying within sensorimotor stage, between birth and two years, the child’s development is too reflexive. Gleitman, Fridlund and Reisberg (2004) discuss the critical period hypothesis and suggest the young brain being more suited to acquisition than the adult brain. Lenneberg (1967) (as cited in Gleitman et al 2004) advocates, brain maturation closes language acquisition capacity window. Kuhl (2010) identified, within the critical period babies develop

In the other hand, behaviorists view language as complex and leaned skill, much like playing piano and dancing. B.F. Skinner argued that language represents nothing more than chains of responses acquired through reinforcement. Putting differently, children learn though process of reinforcement. For example, baby babbles “mama” the mother happily reward the baby with a hug and kisses and eventually will push the baby to say “mama” more and more; due to these reward children are motivated to repeat the behavior, thereby shaping their language and ensuring their development. Children’s language is being built up, this describe a way in which children environmental experiences influence and improve their language skills. Also that’s why parents

Numerous theories try to explain the process of language acquisition. These theories fall into one of two camps. The environmentalist (or connectionist) theory of language acquisition asserts that language is acquired through environmental factors (Halvaei et al. 811). Theorists in this camp believe that a child learns language by gaining information from the outside world and then forming associations between words and objects. The nativist (or rationalist) approach, on the other hand, asserts that it is innate factors that determine language acquisition. Noam Chomsky, often described as “the father of modern linguistics”, falls into this camp as he believes that speech is the result of hidden rules of language that are hidden somewhere in the brain (Rahmani and Abdolmanafi 2111). Steven Pinker, a colleague of Chomsky, is a renowned psychologist, cognitive scientist and linguist who discusses his own theories on language acquisition in his book Words and Rules.

According to Zukowski (2013), language development refers to the process of learning in early life where infants acquire various forms, meaning and word usage. In addition, language refers to the different utterances in regards to linguistic input. Language development in childhood focuses on major arguments in
