Key Terms to Review (18)
Age of acquisition: The age of acquisition refers to the age at which a person first learns a language, which can significantly influence their proficiency and fluency in that language later in life. This concept plays a crucial role in understanding how individuals become bilingual, as it can differentiate between those who learn two languages simultaneously from birth and those who learn a second language later on. The timing of language exposure can also impact language retention and loss over time.
Bilingual proficiency tests: Bilingual proficiency tests are assessments designed to measure an individual's ability to use two languages effectively in various contexts, focusing on skills such as reading, writing, speaking, and listening. These tests can be particularly relevant in distinguishing between simultaneous bilingualism, where a person learns two languages from birth, and sequential bilingualism, where a second language is learned after the first is already established. Understanding bilingual proficiency is essential for evaluating language development and educational needs in diverse linguistic environments.
Code-switching: Code-switching refers to the practice of alternating between two or more languages or language varieties in a single conversation or context. This phenomenon is particularly common among bilinguals and reflects the speaker's linguistic adaptability, cultural identity, and social dynamics.
Cognitive Flexibility: Cognitive flexibility refers to the mental ability to switch between thinking about different concepts or to think about multiple concepts simultaneously. This skill plays a crucial role in adapting to new information, adjusting one's behavior in response to changes in the environment, and managing multiple languages or tasks, especially in bilingual individuals.
Critical Period Hypothesis: The Critical Period Hypothesis suggests that there is a specific window of time during which language acquisition occurs most easily and effectively, typically believed to be from early childhood until puberty. This idea connects to various aspects of language learning, including how age affects second language acquisition, the cognitive and biological foundations of language, and individual differences in language skills.
Cross-sectional studies: Cross-sectional studies are observational research methods that analyze data from a population at a specific point in time. This approach is widely used to gather information about various phenomena, making it relevant for understanding aspects of language development and acquisition across different age groups and contexts.
Early bilingualism: Early bilingualism refers to the ability of individuals to acquire and use two languages from a very young age, typically before the age of three. This early exposure to two languages can significantly influence cognitive development, language processing, and social interactions throughout life, shaping how individuals manage and utilize their linguistic skills in various contexts.
Exposure: Exposure refers to the amount of contact an individual has with a language, which can significantly influence their ability to learn and use that language. In the context of bilingualism, exposure is crucial in determining how effectively a person acquires and utilizes both languages. It affects vocabulary development, pronunciation, and overall fluency, making it a vital factor in understanding bilingual language acquisition.
Interlanguage Theory: Interlanguage theory refers to the evolving linguistic system that emerges in a second language learner's speech, reflecting elements of both their native language and the target language. This theory highlights how learners create a unique set of rules and structures as they transition between languages, leading to systematic errors that provide insight into their learning process. It connects to simultaneous and sequential bilingualism by demonstrating how different learning timelines can affect the nature of interlanguage development, and it plays a crucial role in bilingual education by informing teaching strategies tailored to the learner's current linguistic state.
Language Dominance: Language dominance refers to the degree of proficiency and usage of one language over another in a bilingual individual or community. This concept is essential in understanding how bilinguals navigate their language skills, influencing their communication patterns, identity, and cognitive processes. It can affect phenomena like code-switching, where a speaker shifts between languages based on context, as well as the development of language skills in simultaneous versus sequential bilinguals.
Language maintenance: Language maintenance refers to the efforts and processes involved in preserving and continuing the use of a language within a community, especially when faced with pressures to shift to another dominant language. This concept is crucial for understanding how bilingual or multilingual individuals and communities strive to keep their native or heritage languages alive across generations, particularly in the context of simultaneous and sequential bilingualism, as well as language policies that aim to support or hinder these efforts.
Language shift: Language shift refers to the process by which a community of speakers gradually abandons their native language in favor of another language, often due to social, economic, or political pressures. This phenomenon highlights how linguistic preferences can change over generations, leading to the decline of minority languages and the dominance of more widely spoken languages.
Language transfer: Language transfer refers to the influence that a person's first language has on the learning and use of a second language. This phenomenon can manifest as positive transfer, where similarities between languages facilitate learning, or negative transfer, where differences lead to errors. Understanding language transfer is crucial for assessing bilingual development, particularly in contexts involving simultaneous or sequential bilingualism and bilingual education strategies.
Late bilingualism: Late bilingualism refers to the acquisition of a second language after the critical period for language development, typically around the age of 7. Individuals who become bilingual later in life often face unique cognitive and linguistic challenges that can influence their proficiency and processing of both languages. This concept is closely tied to how bilinguals manage language tasks and differentiate between languages, particularly when comparing those who learn languages simultaneously versus sequentially.
Longitudinal studies: Longitudinal studies are research designs that involve repeated observations of the same subjects over a period of time, allowing researchers to track changes and developments in various phenomena. This method is particularly useful in understanding language development as it captures the dynamic process of acquisition and the factors influencing it across different stages and contexts.
Metalinguistic awareness: Metalinguistic awareness refers to the understanding and reflection on the nature and functions of language. It involves recognizing language as a system, which can enhance cognitive skills, especially in bilingual individuals who can navigate between different languages and linguistic structures, leading to improved analytical and critical thinking abilities.
Sequential bilingualism: Sequential bilingualism refers to the process where a person learns a second language after they have already acquired their first language. This type of bilingualism often occurs when individuals are exposed to a new language later in childhood or adulthood, and can impact cognitive development, language processing, and educational outcomes differently compared to those who learn two languages simultaneously.
Simultaneous bilingualism: Simultaneous bilingualism refers to the ability of an individual to acquire two languages at the same time, typically from birth or in early childhood. This phenomenon allows for the natural integration of two languages into a person's cognitive framework, often leading to a more balanced proficiency in both languages. It relates closely to the neurobiological underpinnings of language processing, the distinction between simultaneous and sequential bilingualism, and the approaches used in bilingual education.
