Introduction
Bilingualism is crucial for effective social interactions and improved communication skills. Increased globalization has led to the need to interact with individuals worldwide. Second language acquisition (SLA) involves learning a second language and the process involved.
Linguists regard SLA as a sub-discipline of applied linguistics, but it spans other branches of psychology and education. As a scientific field, various factors determine SLA and must be considered for effective learning. While SLA is beneficial for social interactions and cognitive development, social, biological, and pedagogical barriers may affect the acquisition of a new language.
Meaning of SLA
SLA is a multidimensional concept, and its meaning varies depending on the context used. The term can mean acquiring and learning a new language apart from the first language (Perkins & Zhang, 2022). For instance, an English-speaking person can learn about Germany through the process of SLA. Additionally, the term can mean a sub-discipline of applied linguistics.
The sub-discipline involves the scientific study of exploring the factors, benefits, barriers, and importance of acquiring a new language (Castro et al., 2022). SLA involves the application of the input hypothesis, a concept developed by linguist Stephen Krashen (Chen, 2022). According to Stephen Krashen, language acquisition and learning are distinct: the former is subconscious, whereas the latter is a conscious process (Perkins & Zhang, 2022). Therefore, the meaning of SLA is contextual and depends on its application.
Factors and Approaches SLA
As discussed above, SLA is a learning process and can be affected by various factors. Although many factors influence learning a second language, cognitive, social, linguistic, and personal variations dominate. The extent of the influence of factors on SLA varies from one individual to another. Consequently, some learners may find it easier to acquire a second language than others. For instance, languages that are similar to a person’s first language are acquired faster than completely different languages. A learner needs to adopt effective approaches to SLA for effective learning.
Cognitive
The cognitive approach to SLA involves the mental processes of acquiring a second language and an explanation of the learner’s knowledge. Cognitive abilities such as memory, attention, and problem-solving skills are crucial in determining the effectiveness of SLA. Individuals with high memory capacity can easily learn a new language (Wallace, 2020).
Meanwhile, the ability to pay attention determines how a learner understands the basics of the second language, including pronunciation, spelling, and grammatical rules associated with the language. Cognitive learning theory is used to explain the role of cognition when learning a new language. Therefore, SLA is a conscious thinking process involving learning strategies that enhance information comprehension, learning, and retention.
Social
Language is a tool for communication and, consequently, interactive activities among members of society. Although society and culture are distinct concepts, they are applied together since an individual cannot mention culture without thinking of society. Therefore, social-cultural factors can be described as the factors within a society that affect SLA (Amir & Razmjoo, 2022). The sociolinguistic setting, specific social factors, and situational factors are the common elements of society that affect the acquisition of a second language (Wallace, 2020). For instance, stereotyping and lack of identification with culture can make it difficult to learn a language associated with a given culture.
Linguistic
The linguistic approach to SLA is distinct from the sociocultural and cognitive approaches. The linguistic method of SLA involves generative approaches informed by universal grammar and typological mechanisms (Castro et al., 2022). Some factors associated with the approach to SLA are vocabulary, self-efficacy, and mother tongue interference. For instance, it is difficult to learn a language with a complex vocabulary whose spellings they cannot relate to. Additionally, some mother tongues have grammar rules that can contradict those of the second language (Minkhatunnakhriyah et al., 2022). Therefore, learners should consider context and expectations, code-switching, and speech intelligibility when learning a second language.
Individual Variations
Although SLA depends on sociocultural, cognitive, and linguistic factors, individual variations can determine the effectiveness of acquiring a new language. Individual variation factors involve those that are unique to a learner. Age, gender, and motivation are some of the individual variation factors determining SLA (Amir & Razmjoo, 2022). Cognitive and neural capabilities develop with age and decline as one grows older. Individuals between eight and twelve years have better second language learning skills than those above forty (Castro et al., 2022). Older individuals have SLA difficulties, including language production deficits, word-finding failures, and increased pauses in speech (Perkins & Zhang, 2022). Consequently, older adults struggle to acquire a second language, which may require extra effort.
While SLA is beneficial, not all individuals are interested in knowing another language apart from their first one. Motivation involves the extent to which an individual is ready to learn a new language. Intense practice and willingness to interact with new people can motivate an individual to acquire a second language. It is difficult to learn a second language if they do not want to. Meanwhile, females can learn a second language more easily than males due to the strategies adopted (Minkhatunnakhriyah et al., 2022). According to Amir and Razmjoo (2022), females use more learning strategies than males, who only use analytical approaches. Educators should consider cognitive, sociocultural, linguistic, and individual variations factors when imparting SLA knowledge.
Stages of Second Language Acquisitions
SLA is not an instantaneous event but a long-term process that involves understanding simple language rules and complex ones. While the factors discussed above are crucial in determining how fast one can learn a second language, one must go through various distinct stages of learning. Linguists have tried to define and determine the stages that learners go through when acquiring a second language. Krashen, Kleine, and Perdue stages are the most commonly identified levels of SLA (Chen, 2022). Krashen’s stage involves five steps of SLA, but Kleine and Perdue’s stage is a three-pronged level of SLA.
Krashen’s Stages
The stages were determined by Stephen Krashen, and it involves five levels: preproduction, early production, speech emergence, intermediate fluency, and advanced fluency. The preproduction stage is the “silent period” since an individual takes in the new language but does not speak it (Chen, 2022). Individual variations coupled with other factors and approaches determine the duration of the first stage. However, on average, the stage takes up to six weeks or longer if the influencing factors remain constant (Castro et al., 2022). It is important to note that not all learners go through the first stage since some may start speaking the language directly but with some limitations.
The “silent period” is followed by the early production stage, the second stage. During early production, individuals show little understanding of the new language and speak in short phrases of one or two words (Minkhatunnakhriyah et al., 2022). Although learners can memorize a chunk of the new language, they often make mistakes when speaking it.
In the third stage, speech emergence, an individual’s vocabulary count increases to about 3000 words (Lahey & Rizopoulos, 2022). The learners can speak in simple phrases and questions, although they may have grammatical errors. During the intermediate fluency stage, the vocabulary count increases to about 6000 words with more complicated phrases used by learners (Lahey & Rizopoulos, 2022). Finally, the advanced fluency stage is reached after about five to ten years. During the final stage, the learners’ mastery of the second language is almost close to that of native speakers.
Kleine and Perdue Stages
Unlike the Krashen stages, Wolfgang Klein and Clive Perdue established that SLA proceeds in three stages: pre-basic, basic, and post-basic varieties. The two conducted research on SLA at the Max Planck Institute for Psycholinguistics by exploring SLA among adult immigrants in Europe (Amir & Razmjoo, 2022). The first stage, pre-basic, is very terse and involves the acquisition of a small noun lexicon without verbs. Consequently, learners cannot make sentences during the pre-basic stage.
The second stage, basic, there is the introduction of verbs but in their basic forms. The learners can make simple sentences, but they have difficulties using the past and participle forms of verbs (Lahey & Rizopoulos, 2022). Finally, the post-basic stage involves learners showing fully functional morphology with nouns and verbs flection. The Krashen stages are more specific than the Kleine and Perdue stages, making them more appropriate in describing the SLA process.
Benefits of SLA
Learning a second language can be difficult but beneficial for socialization and other interactive activities. Therefore, individuals learn a second language for various reasons that benefit them. Firstly, being bilingual helps people advance their careers since the interconnected world requires the capacity to live in diverse cultures. For instance, English-speaking teachers have more career opportunities in China if they learn Chinese. Secondly, SLA enhances the ability to multitask among individuals. Time management and multitasking are crucial skills that can help an individual. Switching between more than one language allows a person to think differently and from a diverse perspective.
Third, SLA improves a learner’s memory and brain functions by acquiring new skills. New language acquisition pushes individuals’ brains to learn and practice new grammar and vocabulary rules (Lahey & Rizopoulos, 2022). Consequently, the brain capacity and thinking process are effectively enhanced. Lastly, SLA improves students’ performance and academic progress in specific areas. The students are often fully immersed in the new language, promoting their communication skills, which are crucial for participating in class and extracurricular activities (Wallace, 2020). Therefore, adopting effective SLA approaches promotes effective interactions and cognition among learners.
Barriers to Second Language Acquisition
Various factors can encumber SLA, making it difficult for an individual to gain new skills. Although there are many barriers to SLA, linguists have categorized them into social, biological, and pedagogical. Social barriers to SLA involve a cultural and interactive process that limits a person’s capacity to learn a second language. Some of the social barriers are racism, stereotyping, and discrimination. For instance, it may be difficult for an African American to learn a new language from a community that is racist. The learner will have problems with socializing with the racist community and may receive a negative reception.
Meanwhile, biological barriers are inherent among learners and those with which they are born. Some of the biological barriers include poor cognitive capability due to premature birth. Children who were born prematurely and underweight have difficulties learning a new language. Pedagogical barriers involve the approaches and techniques adopted in imparting new language knowledge. The choice of teaching practice approach can be detrimental to SLA. For instance, the use of complex vocabulary in teaching a learner a new language for the first time can discourage them. Educators and learners must determine the most effective technique for learning a new language.
Recommendations for Improving SLA
Although SLA is dependable on the learner’s needs and circumventing conditions, some general recommendations can improve the process. Educators and learners can integrate technology into their learning activities. Using spelling and pronunciation mobile applications can help improve and fasten the acquisition process (Haikal & Rozi, 2022). Additionally, self-reliance among the learners should be encouraged to enhance creative thinking. Educators should only be involved in learning complex sentence structures. Furthermore, SLA can involve interactive activities such as associating with native language speakers (Haikal & Rozi, 2022). Adopting the recommendations discussed above can help improve SLA.
Conclusion
SLA is beneficial for learners and individuals who are interested in understanding new cultures. However, acquiring a new language is influenced by various factors such as cognitive, social, linguistic, and individual variations. Learners must consider the impact of the listed factors on their SLA process. Learning a second language is not immediate and involves various stages, from preproduction to advanced fluency. SLA can be encumbered by biological, pedagogical, and social barriers. Given the benefits of SLA, learners should adopt techniques that eliminate language-acquisition barriers while promoting effective learning.
