The Critical Period of Language Acquisition Theory Language acquisition is critical in the early stages of childhood. It plays a key role in developing communication skills within an individual. In extreme cases, like Genie, the detrimental effects of missing first language can be seen easily with her lack of communication skills and ‘animal’-like behaviour. Feral children such as Genie have been researched in order to understand the detrimental effects of complete social isolation during this critical period. Animals are also great example of how exposure is extremely important in this development. Brain development and stimulation are key elements in gaining language skills; the critical period for language acquisition relies on this stimulation and exposure in order to develop properly. Being deprived of this critical period can result in little to no development in the language region of the left hemisphere of the brain. Without this development a person cannot gain adequate communication skills; they will not be able to form sentences, learn a vast amount of words, or gain understanding of grammar rules. Language acquisition is the period in time in which a person develops their communication skills. They begin the process of learning how to understand and use language, string together sentences, learn grammar rules and begin their knowledge of their first language by learning words in it (Suanda; pg. 2). First language is the development of these skills in infants all the way until puberty. It is also known as the Critical Age Hypothesis, which states that biologically, the basis of language and the ability to learn your first language is all within a fixed... ... middle of paper ... ...is a legend that Psamtik I, the Saitic king of Egypt in the 7th century BCE “assumed that the first word uttered by a child, if they never heard anyone speak, would be in the original language” and in this case, he thought that would be Ancient Eygpytian (Saxton; pg. 57). He isolated a child in the hopes to discover if his hypothesis was correct. Unfortunately, history does seem to repeat itself when cases such as Genie’s are discovered. These horrific cases however, have helped researchers establish the understanding that the critical period for language acquisition is vital, and without adequately going through this stage and stimulating the left hemisphere of your brain, a person can grow up with little to no language capabilities. They will resemble a person who has suffered a brain injury, like Sarah Scott, and will not be able to function socially in society.
When most people think of the process of language development in “normal” children, the concepts that come to mind are of babies imitating, picking up sounds and words from the speakers around them. Trying to imagine that a child who cannot hear one single sound a person makes can learn to speak a language is absolutely fascinating. These children range from amazin...
This essay is about a child’s development and learning, focusing primarily on language development. It will describe the main stages of developmental "milestones" and the key concepts involved for children to develop their language skills, discussing language acquisition and social learning theory. The essay will also look into the key theorists involved in language development, primarily Vygotsky and Chomsky, and how these theories have had an impact on the way society views language and their implementation within schools. The essay will describe the factors affecting language development, both biological and environmental. While also discussing key arguments among theorists, one being the nature vs nurture debate, and how these play a part in the teaching in schools.
There are three main theories of child language acquisition; Cognitive Theory, Imitation and Positive Reinforcement, and Innateness of Certain Linguistic Features (Linguistics 201). All three theories offer a substantial amount of proof and experiments, but none of them have been proven entirely correct. The search for how children acquire their native language in such a short period of time has been studied for many centuries. In a changing world, it is difficult to pinpoint any definite specifics of language because of the diversity and modification throughout thousands of millions of years.
Genie’s case demonstrates that although it is possible with extensive training to acquire some language after the critical period, a mastery of language after this period is not possible. Aspects such as vocabulary and certain conversational skills (textbook) are possible but the underlying grammar Genie’s lack of lateralization highlights the relationship between language and lateralization although it is unclear language input is a prerequisite for language acquisition.
This essay is going to illustrate the different stages in language acquisition that children pass through and elicit the theories in accordance.
Child development language is a process by which children come to communicate and understand language during early childhood. This usually occurs from birth up to the age of five. The rate of development is usually fast during this period. However, the pace and age of language development vary greatly among children. Thus, the language development of a child is usually compared with norms rather than with other individual children. It is scientifically proven that development of girls language is usually at a faster rate than that of boys. (Berk, 2010) In other terms language development is also a crucial factor that reflects the growth and maturation of the brain. However, this development usually retards after the age of five making it very difficult for most children to continue learning language. There are two major types of language development in children. These include referential and expressive language development styles. In referential language development, children often first speak single words and then join the words together, first into –word sentences and then into th...
...Pines, 1997). After being trained, when she tried to convey her messages to the experimenters, she used basic one-word or two-word structures, such as “stop it”, “no more”, and “jump”, when she wanted to jump as opposed to saying “I want to jump” or “I like to jump” or “Jumping is fun”. Experts have tried to teach Genie to learn language at a higher level, but she was not able to do so because she missed the critical period. During a child’s development, there are series of time periods in which a child can best learn or refine a particular ability, such as speech. After this time period is over it becomes much more difficult, sometimes impossible, for the child to learn the same thing just as in Genie’s case. With this in mind, it is important for researchers to continue to observe and learn about language acquisition. Where it starts (the womb) to what critical periods an infant or child will have the greatest window of opportunity is very important if we are going to overcome some of the language disabilities that we have. In a world where babies are born prematurely and mothers are having drug exposed and positive toxic babies, it is imperative that the research continues.
... (p. 116). In her article, “Babies Prove Sound Learners,” Sohn (2008), states, “Such studies show that, up to about 6 months of age, babies can recognize all the sounds that make up all the languages in the world” (para.24). B.K. Skinner suggest that the materialization of language is the result of imitation and reinforcement. According to Craig and Dunn (2010), “Language development is linked to cognitive development that, in turn, depends on the development of the brain, on physical and perceptual abilities, and on experiences. Biological and social factors also jointly influence the early development of emotion and personality” (p. 117). In her article, A natural history of early language experience. Hart (2000), states, “Talking is important for children, because complexity of what children say influences the complexity of other people’s response” (para. 1).
The tragic case of feral child Genie provides a unique perspective on the roles of socialization and linguistic exposure as they relate to post-puberty language acquisition. After eleven years of isolation and abuse, Genie was discovered possessing no known language, having already passed what has theorized to be the critical period. Utilizing a variety of methods and testing, professionals attempted to aid Genie in first language acquisition over the next five years with little success. Using examples of stalled grammatical development, language acquisition compared to both normal children and late learners of American Sign Language (ASL); and the roles of linguistic exposure, socialization and brain lateralization, this paper will demonstrate support of the theory of critical period for first language acquisition as it relates to Genie’s case.
Wilder Penfield and Lamar Roberts first introduced the idea that there is a “critical period” for learning language in 1959. This critical period is a biologically determined period referring to a period of time when learning/acquiring a language is relatively easy and typically meets with a high degree of success. German linguist Eric Lenneberg further highlights Roberts and Penfield’s findings and postulated the Critical Period Hypothesis in 1967. According to the Critical Period Hypothesis (CPH), certain biological events related to language development can only happen in the critical period. During this time, the brain possesses a degree of flexibility (ability and ease of learning a language) and becomes lateralized (assignment of language functions becomes concrete – either in the left or right hemisphere) (Marinova-Todd, S; Marshall, D & Snow, C. 2000 9-10). This critical period lasts from childhood through the onset of puberty (usually at around 12 years of age). Once this period is over, it is more difficult to learn a language because language functions in the brain have become concrete. This hypothesis can be seen with the case of Genie, a woman who was isolated from human interaction and language up to the age of 13. By the time she was rescued, she was well after the critical period for language acquisition, and as such, she did not have a full command of the English language. Had she been rescued before the age of 13, she may have had more linguistic capability. However, this accounts for firs...
The critical period hypothesis for language acquisition was popularized by neurologist Eric Lenneberg. The hypothesis suggests that if an individual is not exposed to language during a specific period in their childhood then they will have great difficulties acquiring language later in life (Redmond, 1993). I believe the two “wild children” cases of Genie and Victor provides evidence to support the critical period hypothesis. Genie’s case supports the hypothesis because although she developed a vocabulary and despite all of her intense therapy sessions, she still was not able to create meaningful and grammatically correct sentences (Garmon, 1994). Genie’s inability to create real sentences may indicate that she endured the extreme deprivation during her critical period and it prevented her from acquiring language. Victor’s case also supports the critical period hypothesis. The professionals in the documentary The Secret of The Wild Child stated: “While Victor knew how to read simple words, he never learned how to talk” (Garmon, 1994). This quote implicates that similar to Genie, Victor developed a vocabulary,
Imitation is involved to some extent, of course, but the early words and sentences that children produce show that they are not simply imitating adult speech. Since there is an infinite number of potential sentences implied, children’s complex and creative utterances cannot be explained by a passive response to the language of the environment. In addition, imitation cannot account for common child language mistakes, which are highly unlikely to be failed imitations of what adults would say (Cattell, 2000).
The aim of this essay is to explore language acquisition and compare and contrast different theories of language acquisition and language development. Language in its most basic form is used to communicate our needs and wants. It encompasses a range of modes of delivery including signing, spoken and written words, posture, eye contact, facial expressions and gestures. So how do we learn ‘language’? Are we born with the skills for communication, or is it something that we have to learn or have taught to us? Four theories are looked at in this essay to determine how children acquire and then develop language. These theories include behaviourist, nativist, cognitivist and sociocultural. This essay will highlight some similarities and differences in each theory and what impact these have on a child’s acquisition and development of language. Lastly we will look at the implications of these theories when working with children. Can a classroom teacher deliver a quality literacy program based on just one of these theories or does it need to incorporate components of all four? Sims, (2012) pp. 21 states ‘’High-quality learning experiences in the early years of life enhance children’s cognitive and language skills’’. This places a great responsibility on educators and teachers alike to provide an environment which is rich in learning opportunities that will encourage both the acquisition and development of language.
Still today, it is the commonly held belief that children acquire their mother tongue through imitation of the parents, caregivers or the people in their environment. Linguists too had the same conviction until 1957, when a then relatively unknown man, A. Noam Chomsky, propounded his theory that the capacity to acquire language is in fact innate. This revolutionized the study of language acquisition, and after a brief period of controversy upon the publication of his book, Aspects of the Theory of Syntax, in 1964, his theories are now generally accepted as largely true. As a consequence, he was responsible for the emergence of a new field during the 1960s, Developmental Psycholinguistics, which deals with children’s first language acquisition. He was not the first to question our hitherto mute acceptance of a debatable concept – long before, Plato wondered how children could possibly acquire so complex a skill as language with so little experience of life. Experiments have clearly identified an ability to discern syntactical nuances in very young infants, although they are still at the pre-linguistic stage. Children of three, however, are able to manipulate very complicated syntactical sentences, although they are unable to tie their own shoelaces, for example. Indeed, language is not a skill such as many others, like learning to drive or perform mathematical operations – it cannot be taught as such in these early stages. Rather, it is the acquisition of language which fascinates linguists today, and how it is possible. Noam Chomsky turned the world’s eyes to this enigmatic question at a time when it was assumed to have a deceptively simple explanation.
Language acquisition requires meaningful interaction in the target language with natural communication while children are acquiring the foreign language. Children usually concerned with message which they are conveying and understand not with the form of utterances. These utterances are initiated by the acquired systems and the fluency of language is based on what we have ‘picked up’ through active communication. Both formal knowledge and conscious learning of the second language learning may be alternate to the output of the system, sometimes before and sometimes after the
