Summary and Critique of Johnson and Newport 1989

Many popular theories of second language acquisition have been analyzed throughout history. The socialization of L2 learners, their present emotional state that is present at time of acquisition, as well as the comprehensible input and output with the use of scaffolding play a major role in second language acquisition. Let us also not forget the importance of written expression as well as reading comprehension with these L2 learners. Each play a role in language development. However, I believe that in acquiring a language, one must use a variety of techniques that work together to create a balance within the learning environment. Furthermore, all L2 learners learn differently and so a variety of resources will need to be used based on the ability of each student. There are many theories that have been developed by highly qualified experts in the field on linguistics. However, I will address those areas that I agree with as I present my personal theories on second language acquisition.

The second portion of the article is all about the stages of second language acquisition of which there are 5. In order from low level of linguistic proficiency to high level of language proficiency the five levels – as stated by the article- are: Silent/Receptive/Pre-productive, Early Production, Speech Emergence, Intermediate Fluency, and Advanced Fluency. The article goes on to

When its comes to language it shows that in our childhood our brains are more flexible in adapting to new types of information. When we're younger it's easier to pick up than we get older. Even when we get older learning a new language may not be easy but it's not impossible. It just interference between the new and old languages. Which makes it take time to learn a new language. Age has a part in learning a language the older we get the harder it is to remembering things. So critical period of language is when you are

Johnson and Romanello (2005). Each unique generation comes with diverse learning and teaching needs. Therefore, nurse educators must be knowledgeable in a multitude of teaching methods and learning theories.

In contrast, “some adults have been known to acquire an authentic accent in a second language after the age of puberty, but such individuals are few and far between” (Brown, p.61, 2007). A study conducted by an anthropologist named Sorenson in the 1960’s conflicts with the Critical Period Hypothesis by proving that adults can in fact attain a perfect fluent second language acquisition just like a native speaker. This became evident when Sorenson studied the Tukano culture in South America in which people have to marry outside their ethnic group. Therefore, they marry someone who speaks another language. Once they marry into their spouse’s ethnic community they immediately start learning that specific language. Sorenson reported, “during adolescence,

One of the reasons for this stereotype can be attributed to the older adult and the teacher, they have doubts about their ability to learn a foreign language. Although most people have accepted the generalization of learning as “the younger the better” (Schleppegrell, M., 1987), this is not the case when it comes to learning language. There have been studies that have determined that aging does not decline a person’s learning ability. The way older adults learn a new skill is the only adjustments that need to be made. These studies also show that older adults learn at a more rapid rate than children (Krashen, Long, and Scarcella, 1979). There are two reasons why being a poor language learner is attributed to adults, and those are “a theory of the brain and how it matures, and classroom practices that discriminate against the older learner” (Schleppegrell, M., 1987). The "critical period" hypothesis that was put forth in the 1960 's was based on then-current theories of brain development, and argued that the brain lost "cerebral plasticity" after puberty, making second language acquisition more difficult as an adult than as a child (Lenneberg, 1967). Due to advances in the study of neurology, it has been determined that adults have superior language learning capabilities. These studies and facts should dispel any accepted stereotypes related to older adults and their ability to learn foreign languages.

Many second language acquisition theories have been developed over the years. These theories examine the avenues in which second language is acquired and the avenues in which they are

The critical period of child language acquisition remains of most interest, as this is where the brain is most malleable and receptive to change – however, later language development will also be addressed. Interpretations of findings and results in this essay stem from a nativist

There are several theories regarding language development. Work by Chomsky, Piaget and Kuhl are critical. Studies by Chomsky, as examined by Albery, Chandler, Field, Jones, Messer, Moore and Sterling (2009); Deloache, Eisenberg & Siegler (2003) argued for the innateness of language acquisition due to its complexity. Development is assisted by a language acquisition device (LAD) and universal grammar both of which holding the propensity for commonalities throughout all languages. LAD is the key to the Syntax rule. The knowledge to master the rules is held unconsciously. Chomsky concludes exposure through auditory channels as being the only requirement for learning. Arguably Kuhl (2010) writes infantile exposure to language through auditory channels only, does not contribute effectively to learning indicating the importance of human interaction. Piaget, as discussed by Ault (1977) postulated language as not being part of the earliest stages of development. Signifying within sensorimotor stage, between birth and two years, the child’s development is too reflexive. Gleitman, Fridlund and Reisberg (2004) discuss the critical period hypothesis and suggest the young brain being more suited to acquisition than the adult brain. Lenneberg (1967) (as cited in Gleitman et al 2004) advocates, brain maturation closes language acquisition capacity window. Kuhl (2010) identified, within the critical period babies develop

Early language development predicts the amount of vocabulary knowledge as the child develops and is a key factor that is linked with later academic achievement (Pungello et al., 2009; Weisleder & Fernald, 2013). Also, background factors must be analyzed and assessed, in order to understand how language growth differs from one child to the next. Exposure to speech is very important and helps influence early development of language and the processing speed (Fernald, Marchman, & Wielder, 2013 as cited by Weisleder & Fernald, 2009). A study done by Kwon et al., (2013), found that play has a significant effect on the language complexity for children’s language use pertaining to the structure of play or activity setting (free play), however the gender of the parent did not influence the language growth for the child. Furthermore, children are able to identify familiar words when speech is directed towards the child and not over heard, facilitated vocabulary learning at the age of 24 months (Weislder & Fernald, 2013). For example, over hearing adult conversation is not as beneficial towards the child’s vocabulary learning.

Language carries the beauty and persona of our thought process and the study of Linguistics helps us develop insights, appreciate and analyze many aspects of this powerful medium of expression. My fascination with Second Language Acquisition (SLA) began with the course ‘Language Acquisition and Learning’ that I took while I was in the 4th year of my undergraduate program at the University of Dhaka. In that course, for the first time, I was introduced to various theories and hypotheses about how people acquire a second language, such as Stephen Krashen’s five main hypotheses on language acquisition (the acquisition-learning hypothesis, the monitor hypothesis, the natural order hypothesis, the input hypothesis, and the affective filter hypothesis), Larry Selinker’s Interlanguage theory, John Schumann’s Acculturation model, and Howard Giles’s Accommodation theory. These theories helped me realize the robustness and richness of SLA research and made a permanent impression on my mind about this field. Besides SLA, I was also acquainted with Psycholinguistics through this course. I have learned about several theories of first language acquisition, e.g. the Behaviorist theory, the Innatist theory, the Cognitive theory, and the Maturational theory. It is worth mentioning here that this course really helped me set my dream to become an academic as well as a researcher in the field of language acquisition and learning.

The first area of difference between first (L1) and second (L2) language learning is input – specifically the quality and quantity of input. It is the idea of the "connectionist model that implies... (that the) language learning process depends on the input frequency and regularity" (5).. It is here where one finds the greatest difference between L1 and L2 acquisition. The quantity of exposure to a target language a child gets is immense compared to the amount an adult receives. A child hears the language all day everyday, whereas an adult learner may only hear the target language in the classroom – which could be as little as three hours a week. Even if one looks at an adult in a total submersion situation the quantity is still less because the amount of one on one interaction that a child gets for example with a parent or other caregiver is still much greater then the adult is receiving.

When discussing about “In other words”, Bialystok and Hakuta state that there is some thought that children who may appear to be learning a second languge very quickly at a vey young age (before the age of 5). They further state that accompanied by the loss of their first language, have really replaced the first language with the second language.

The idea of critical period for language acquisition was first brought into view by Eric Lenneberg in 1967. The critical period hypothesis states that idea that the learning of a language must be done within a certain time frame after a child's birth, or else it will be impossible for the acquisition of language to happen. Though Lenneberg may have not been the one to have thought up the idea, he was the person who had popularized it making psychologist question whether or not such a thing as a critical period exists(Snow). This hypothesis first came up from studying people who acquired some sort of damage to the left hemisphere of the brain, leading a patient to obtain aphasia. People who were unfortunate enough to obtain this type of language impairment were more likely to recover to having normal language abilities, if they acquired

Abstract: In second language acquisition, age factors has always been the study focus and one of the most controversial issues of linguistics. Based on the Brain Plasticity Theory and the Critical Period Hypothesis, the purpose is to prove such a hypothesis that the younger the leaner who begins to learn an second language,the greater the probability that he or she will achieve a native-like command of it.
