The idea of a critical period for language acquisition, first introduced by linguist Eric Lenneberg in 1967, is a popular debate amongst many people. In his initial discovery of the “critical period hypothesis,” Lenneberg stated: “there are maturational constraints on the time a first language can be acquired. First language acquisition relies on neuroplasticity. If language acquisition does not occur by puberty, some aspects of language can be learnt but full mastery cannot be achieved.” Lenneberg also stressed that in the case of bilingual individuals, the critical period is broken into phases. These individuals must learn their first language in Phase one which ends at age seven and their second language in Phase two which ends at the beginning of puberty. This hypothesis has never been proven accurate due to various conditions that both support and disprove its claim. The critical period hypothesis is based on neuroplasticity, the idea that intact parts of the brain can take over the functions of a damaged part (Harley, 2010). This plasticity, however, is primarily abundant before lateralization, a period of time in which specialization of functions occur in both hemispheres of the cerebral cortex (Berk, 2012). While the brain is still developing, during early childhood, many areas of the cerebral cortex are not yet committed to one function. This allows these areas to be more receptive of creating different neural pathways and acquiring new skills. However, as a child gets older, his or her brain becomes lateralized and neural plasticity decreases, making skills such as communication harder to acquire. Although language acquisition may become harder to acquire as a person gets older, it is not completely impossible. T... ... middle of paper ... ... adapt to the dialect of their new enviornment.

With the diagnosis of disease comes many life altering events. Someone’s world can be turned upside down at the moment it is recognized and these people have no choice but to adjust. Sometimes, the disease has the power to inhibit even the most simple activities, or in some lucky cases, inhibit almost none.
My essay topic is the language development of deaf infants and children. In my opinion, this is an important topic to discuss, due to the lack of public knowledge concerning the deaf population. Through this essay, I wish to present how a child is diagnosed as having a hearing loss (including early warning signs), options that parents have for their children once diagnosed (specifically in relation to education of language), common speech teaching methods used today, typical language development for these children, and some emotional, social, and mental difficulties faced by the deaf child and the child’s family that have an immense effect on the child’s education.
According to Collier (1987, 1988) from the time children are born until about five years of age when they begin to read, children get most of their information via visual observations. It stands to reason that students who are beginning the acquisition of a new language would exhibit the same characteristics regardless of chronological age. Moreover, Paivio
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.

Language acquisition is perhaps one of the most debated issues of human development. Various theories and approaches have emerged over the years to study and analyse this developmental process. One factor contributing to the differing theories is the debate between nature v’s nurture. A question commonly asked is: Do humans a...
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...
What is language? Language is a set of arbitrary symbols that enables every individual in the community to communicate and interact. These symbols contain acceptable meanings by the society and culture. Possessing a language is essential in all human; every normal human speaks but nonhuman does not. Acquisition, on the other hand, means learning or getting. Therefore, language acquisition basically means the learning or the gaining of a language. Language acquisition is normally viewed as a part of cognitive science. Many psychologists like Pavlov, Skinner, Jean Piaget, Vygotsky and Chomsky had done researches on this particular field. Language acquisition is an interesting subject to study and discuss on. Every normal child acquires his or first language – usually the mother tongue successfully in their first few years. The matter that most psychologists concern on is the critical age in first language acquisition. Is there a limit in the aspect of age for first language acquisition? Is it true that once a child passes the critical age, he will not be able to learn a language properly?
Language connects human beings together by providing them a way to express ideas and thoughts to one another. The continuous growth of interaction between countries requires a need for more multilingual people in the world, and the value of acquiring a second language can provide people with numerous activities not as easily adaptable for monolingual individuals. A major component of linguistics involves grammar, which are the rules of language. Grammar can be broken down into syntax and semantics. Syntax refers to the system of rules that governs how human beings combine words in order to create sentences, and semantics refers to the context of sentences and provides meaning to what it is that a person is saying (Morris and Maisto 260-261). Jacqueline S. Johnson from the Department of Psychology at Cornell University and her research partner Elissa L. Newport from the University of Illinois provided in their case study, “Critical Period Effects in Second Language Learning: The Influence of Maturational State on the Acquisition of English as a Second Language” that, “some investigators have suggested that a critical period theory must predict that children are better than adults at learning second languages” (63). In order to prove or disprove the idea that children are able to better acquire second languages at a higher rate of proficiency than adults, numerous case studies have been conducted comparing early-language learners with late-language learners. Ultimately, what can be determined is that while second language proficiency is at its highest potential among younger children, there are too many possible variables in individual lives after puberty to accurately pinpoint how successfully an older person develops his multiling...
Here in this essay I will present the different stages of the first language acquisition with young learner, there are too many theories explain how the infants can not only understand the language but also speak it later on.
Qualities of a successful language learner’s Age: Age variation in English learning and learning differences between children and adults are significant factors that must be taken into account in choosing the right approaches, design and procedures. In the survey it has been found that those respondents who had some exposure to English language in their childhood managed to acquire good communication skills. Infants are born as universal receivers of all language sounds, but this ability slowly disappears, as they grow old. So early childhood experiences aid the learners in acquiring good English successfully in later life.
Further in this term-paper I am going to describe the stages in child language acquistion starting from the very birth of an infant till the onset of puberty.
...ions such as why some children have language disorders or how children and adults learn a second language, and we still do not understand what happens when a stroke or a disease such as Alzheimer or any other mental disease seems to erase a person’s knowledge of language. Clarifying the process of language acquisition promises not only to help scientists answer these questions, but to explain elementary features of learning and the human brain.
...rtant point for speaking; critical period hypothesis. If a child starts to learn a second language before the age of 6, s/he will be definitely successful. If a child starts to learn a second language between the age of 12 and 15, s/he will have a chance to be successful but it is very hard to do. In our country, students start to learn a second language at the age of 9(minimum) and it produces poor results.
