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...

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.

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.
In American society, learning to speak English properly is a crucial factor in assimilation. People who have decided to come to America have found it rather difficult to assimilate into American society for several reasons. One reason being that learning a new language is or can be considerably difficult depending on your age. This is so because the act of learning a new language such as English, is much more difficult for an elderly person than for one who has not reached adolescence. According to Grognet, for elderly people there are several factors that affect their willingness to learn. Among those factors are, physical health, mental health, cultural expectations, attitude, motivation and finally the ability to acquire the correct diction, and to suitable articulation (Grognet 296-297). For a person who has not reached the prepubescent age, it is...
Language Development in Children Language is a multifaceted instrument used to communicate an unbelievable number of different things. Primary categories are information, direction, emotion, and ceremony. While information and direction define cognitive meaning, emotional language expresses emotional meaning. Ceremonial language is mostly engaged with emotions, but at some level information and direction collection may be used to define a deeper meaning and purpose. There is perhaps nothing more amazing than the surfacing of language in children.
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...
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.
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.
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...

...language acquisition comes much more easier to children before puberty learners following their age of puberty. Before puberty, the brain and language acquisition among children are so similar that proficiency in a second language is almost developed inherently such as with their first language acquisition. Due to the obstacles including the cultural identification a person holds towards the language’s native country, a person’s fear of being judged by others in speech, and a person’s motivation in acquiring a language, the varying levels of each of these linguistic barriers causes variation among how quickly and successfully adults can acquire foreign languages. All in all, however, it is clear that age does affect the rate of second language acquisition, and it is among the lower age levels where acquisition does reach its highest potential of distinct proficiency.
...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.
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,
A linguist at the Massachusetts Institute of Technology named Chomsky, declared that we have the ability to learn language not only because somebody taught us, but also because we are born with the principles of language in our genes. Chomsky also said “We have language because of nature, not just nurture” (Everywhere Psychology, 2012). Chomsky was one of the people that believed Genie still had a chance to learn language since everybody is born with the ability to learn. A neuropsychologist named Eric Lenneberg, agreed with Chomsky about humans being born with the ability to learn a language as nature, but believed there is a deadline for learning language. Lenneberg believed that if a first language isn 't learned by puberty it could be too late. What Lenneberg proposed is called the "critical period hypothesis," (Everywhere Psychology,
