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...

...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.
There’s a long-standing argument that most people resort to when discussing whether or not children are better suited to acquire a language over adults. The “critical period hypothesis” argues, “that children are superior to adults in learning second languages because their brains are more flexible.” (McLaughlin 2) This argument is true to some extent, however, experimental research has found that adolescents and adults are able to acquire languages better based on their controlled environment. Children, on the other hand, are better able to grasp a better understanding of the pronunciation of languages compared to adults. (McLaughlin
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.
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...

Lateralization is key during this critical period as children naturally and easily acquire the skills for ...
As stated earlier, there are different components to language which must be taught and used in conjunction with context and social situations (Gee & Hayes, 2011). These include phonetic (sound patterns of words), syntactic (sentence structures), semantic (meanings of words and sentences) and pragmatic (using language in certain contexts) mechanisms (Fellowes and Oakley, 2014). Learning these can put meaning and purpose to the language that children learn through their surroundings, including contact with other children and adults, their culture and build upon their cognitive functions. Children in the early years are at a crucial time in their learning, the exposure to language they get from their home environment can set them up for the rest of their educational journey and beyond schooling. McInerney (2014) explores Vygotsky’s theory of cognitive development, explaining that language is used as a communication instrument and a way to organize our own thoughts.
Nearly every member of the human race learns a language or more to the degree of proficiency only in the first few years of life. How children achieve this astonishing skill in such little time has sparked controversial debates among linguists, psychologists, and scientists throughout centuries. Some believe that language is an innate ability possessed by all human beings due to the remarkable function of the brain, while others maintain that language is learned from childhood experience. However, many are beginning to realize that nature and nurture go hand-in-hand when explaining how children develop their language(s). Despite the claims that language is either pre-learned or environmentally learned alone, the combination of both genes and experience better explains the aspects of first language acquisition.
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...
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.
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.
For the purposes of this paper, I have defined adulthood as including any person who is at or above the age of eighteen, because there is so little research on language learning in early adulthood versus middle or late adulthood. It is not possible to find studies about particular divisions of adulthood that have been verified by subsequent research trials, so I have included research about all ages of adulthood. Throughout this paper, I will discuss the major aspects of the body of research literature that separates adult second language learning from that of natural bilingual persons, including full immersion into the language, biological and neurological factors, the structure of both the native and second languages, age of acqui...
The stages of language knowledge develop by stages, and it is suggested, each successive stage approach more approximates the grammar of the adult usage.
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...
Language has pioneered many interracial relationships and historical milestones. Language is a necessity for basic communication and cultural diversity. Being multilingual is a skill proven influential to a successful future. Due to rapid globalization, countries all over the world are stressing the importance of learning a second, or even third, language. With the exception of time and lack of resources, adults have very few widely applicable disadvantages to learning multiple languages. However, language learning as a child presents more complications. Some of those include not having enough funding at the elementary school level to introduce a program for secondary language, academic overload for the youth, stress for both the parent and student parties, and the mixing of languages. Not all of these complications are true in any or all situations, however, and the absence of them provides multitudes of opportunity for future career and academic success. Ultimately, it is the responsibility of the parents or the education legislation to decide whether they encourage the learning of a secondary language at the young age necessary for retention. “The general consensus is that it takes between five to seven years for an individual to achieve advanced fluency,” therefore the younger a child begins to learn, the more likely they are to benefit to the maximum potential (Robertson). Keeping the language learning in high school or beginning the process earlier is a greatly controversial discussion that is important to address because of the topic’s already lengthy suspension.
Children’s acquisition of language has long been considered one of the uniquely defining characteristics of human behaviour.
