Humans are born with the innate capability and knowledge to learn any language. Children can construct mental grammar easily due to such innate knowledge of language. Mental grammar can be defined as unconscious rules/principles of a language a speaker has in his/her mind. However, the ability to learn language is constrained by critical period, a time period in development when the human brain is prepared to construct a mental grammar. After the critical period, our innate ability to learn language diminishes. Test situations centered on the critical period for language acquisition and the input received during such period is essential in furthering comprehending human language. They shed light on how mental grammar are constructed. If there is a critical period for language acquisition and a child receives no linguistic input during that critical period, the child would not be able to develop language to fully capacity. This will occur because the child did not receive the linguistic input during the necessary period to learn a language, critical period. However, because all humans have the innate knowledge to learn a language, the child might still …show more content…
You will not be able to observe a difference between a child who receives full linguistic input early in childhood and the adolescent who only received input after puberty. This will occur because there is no critical period for language acquisition, therefore they do not have a specific period or age in which they would have to learn language. To be more specific, there will not be any constrains on when language must be learned. In addition, the child is born with the innate knowledge and capacity to learn language. However, no evidence supports such scenario, the reasoning behind this is based solely on
After Lenneberg's (1967) advanced analyses and interpretation of critical period in regards to first language acquisition, many researchers began to relate and study age issue in second language acquisition. In this area of study, Johnson and Newport (1989) is among the most prominent and leading studies which tries to seek evidence to test the Critical Period Hypothesis (CPH) in second language (L2) acquisition. This study aims to find identifying answers to the question of age-related effects on the proficiency for languages learned prior the puberty.
William Golding , the author of The Lord of the flies believes that evil resides in all human beings. The Lord of the Flies begins softly but nearing the end everything turns upside down. But would the world be the same way it is today without societal structure and rules? Only through societal structure, rules and order will humans be thought morality/principal and proper behaviour. The Lord of the Flies demonstrates what society would look like/resort to without any rules or guidance for man to follow. Others might believe this is true because of natural evil and actions done by individuals, a comparison through savagery and civilization, and certain truths in the world that are evil.
The analysis of Chomsky’s argument in Christiansen & Chater’s (2008) article suggests that there may be an innate universal grammar (UG), meaning that humans are born with the biological ability obtain...
Eric Lenneberg was the first to propose there existed a critical period to learn a first or native language that was between that began around two and ended with the onset of puberty around thirteen years old. Lenneberg theorized that language acquisition was not possible before age two because of a lack of maturation, while post-puberty acquisition is inhibited by a loss of cerebral placicity occuring when the cerebral dominance of the language function is complete, happening around the time of puberty (Kraschen). “Children deprived of language during this critical period show atypical patterns of brain lateralization” (intro to language) Lenneberg argued that lateralization of the brain during this critical period is key to language acquisition. “The human brain is primed to develop language in specific areas of the left hemisphere but the normal process of brain specialization depends on ear...

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 suggests 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.
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...
In this part, the writer will point out the importance of the biological and neural foundation of language learning by discussing the following :First, the brain anatomy. Second, l...
Children are generally gone through the stage of "first sound", "babbling"," first words", "the two word", telegraphy to infinity" and eventually constructing more complex sentence as the stages move on. Human species genetically acquire their first language out of innateness. Moreover, the difficultness of each language is considered equal are children who acquired their first language.
Over thousands of years language has evolved and continued to develop to what we know it as today. Throughout the years, it has been studied how we learn language and the benefits of learning it as well as the deficits of not learning it. While studying language it is important to consider the language acquisition device, language acquisition support system, and Infant-Directed and Adult-Directed Speech. Not only is it important to learn language in general, but there are specific sensitive periods in which a human must learn the language in order to obtain developmental milestones. The sensitive period is also crucial when learning a second language and can greatly affect the human when speaking that language. During the sensitive period while a child is learning language it is important that they learn the specifics about language structure and the aspects of language. Once the child has learned the aspects of language, they are also emerged into learning universal grammar. Lastly, the learning of language has influenced ontogeny and phylogeny in various ways. This influence will continue to arise as change occurs and humans and the world continue to develop and evolve.
How do children acquire language? What are the processes of language acquisition? How do infants respond to speech? Language acquisition is the process of learning a native or a second language. Although how children learn to speak is not perfectly understood, most explanations involve both the observations that children copy what they hear and the inference that human beings have a natural aptitude for understanding grammar. Children usually learn the sounds and vocabulary of their native language through imitation, (which helps them learn to pronounce words correctly), and grammar is seldom taught to them, but instead that they rapidly acquire the ability to speak grammatically. Though, not all children learn by imitation alone. Children will produce forms of language that adults never say. For example, “I spilled milk on hisself” or “Debbie wants a cookie”. This demonstrates that children have the desire to speak correctly and have self-motivating traits to communicate. This supports the theory of Noam Chomsky (1972)-that children are able to learn grammar of a particular language because all intelligible languages are founded on a deep structure of universal grammatical rules that corresponds to an innate capacity of the human brain. Adults learning a second language pass through some of the same stages, as do children learning their native language. In the first part of this paper I will describe the process of language acquisition. The second part will review how infants respond to speech.
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...
Children’s acquisition of language has long been considered one of the uniquely defining characteristics of human behaviour.
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,
Jim showed no signs of learning language until a speech therapist took up his case at the age of three. Without the human interaction with the speech therapist there was no sign that Jim would have learned to speak. He needed the interaction before his language ability could develop. q If language development was innate, surely it would develop soon after we are able to control our voices, which is soon after one year of age. It does not explain why language takes a few years to develop.
