Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language, as well as to produce and use words and sentences to communicate.
Jean Berko Gleason is a psycholinguist and professor emerita in the Department of Psychological and Brain Sciences at Boston University who has made fundamental contributions to the understanding of language acquisition in children, aphasia, gender differences in language development, and parent–child interactions.
Psycholinguistics or psychology of language is the study of the interrelation between linguistic factors and psychological aspects. The discipline is mainly concerned with the mechanisms by which language is processed and represented in the mind and brain; that is, the psychological and neurobiological factors that enable humans to acquire, use, comprehend, and produce language.
Neurolinguistics is the study of neural mechanisms in the human brain that controls the comprehension, production, and acquisition of language. As an interdisciplinary field, neurolinguistics draws methods and theories from fields such as neuroscience, linguistics, cognitive science, communication disorders and neuropsychology. Researchers are drawn to the field from a variety of backgrounds, bringing along a variety of experimental techniques as well as widely varying theoretical perspectives. Much work in neurolinguistics is informed by models in psycholinguistics and theoretical linguistics, and is focused on investigating how the brain can implement the processes that theoretical and psycholinguistics propose are necessary in producing and comprehending language. Neurolinguists study the physiological mechanisms by which the brain processes information related to language, and evaluate linguistic and psycholinguistic theories, using aphasiology, brain imaging, electrophysiology, and computer modeling.
Elizabeth Ann Bates was a professor of cognitive science at the University of California, San Diego. She was an internationally renowned expert and leading researcher in child language acquisition, psycholinguistics, aphasia, and the neurological bases of language, and she authored 10 books and over 200 peer-reviewed articles and book chapters on these subjects. Bates was well known for her assertion that linguistic knowledge is distributed throughout the brain and is subserved by general cognitive and neurological processes.
Phonological awareness is an individual's awareness of the phonological structure, or sound structure, of words. Phonological awareness is an important and reliable predictor of later reading ability and has, therefore, been the focus of much research.
Roger William Brown was an American psychologist. He was known for his work in social psychology and in children's language development.
In linguistics, grammaticality is determined by the conformity to language usage as derived by the grammar of a particular speech variety. The notion of grammaticality rose alongside the theory of generative grammar, the goal of which is to formulate rules that define well-formed, grammatical, sentences. These rules of grammaticality also provide explanations of ill-formed, ungrammatical sentences.
David Swinney was a prominent psycholinguist. His research on language comprehension contributed to methodological advances in his field.
The Competition Model is a psycholinguistic theory of language acquisition and sentence processing, developed by Elizabeth Bates and Brian MacWhinney (1982). The claim in MacWhinney, Bates, and Kliegl (1984) is that "the forms of natural languages are created, governed, constrained, acquired, and used in the service of communicative functions." Furthermore, the model holds that processing is based on an online competition between these communicative functions or motives. The model focuses on competition during sentence processing, crosslinguistic competition in bilingualism, and the role of competition in language acquisition. It is an emergentist theory of language acquisition and processing, serving as an alternative to strict innatist and empiricist theories. According to the Competition Model, patterns in language arise from Darwinian competition and selection on a variety of time/process scales including phylogenetic, ontogenetic, social diffusion, and synchronic scales.
A sentence word is a single word that forms a full sentence.
Melissa Bowerman was a leading researcher in the area of language acquisition. From 1982-2007, she was a senior research fellow at the Max Planck Institute for Psycholinguistics.
Crosslinguistic influence (CLI) refers to the different ways in which one language can affect another within an individual speaker. It typically involves two languages that can affect one another in a bilingual speaker. An example of CLI is the influence of Korean on a Korean native speaker who is learning Japanese or French. Less typically, it could also refer to an interaction between different dialects in the mind of a monolingual speaker. CLI can be observed across subsystems of languages including pragmatics, semantics, syntax, morphology, phonology, phonetics, and orthography. Discussed further in this article are particular subcategories of CLI—transfer, attrition, the complementarity principle, and additional theories.
The main purpose of theories of second-language acquisition (SLA) is to shed light on how people who already know one language learn a second language. The field of second-language acquisition involves various contributions, such as linguistics, sociolinguistics, psychology, cognitive science, neuroscience, and education. These multiple fields in second-language acquisition can be grouped as four major research strands: (a) linguistic dimensions of SLA, (b) cognitive dimensions of SLA, (c) socio-cultural dimensions of SLA, and (d) instructional dimensions of SLA. While the orientation of each research strand is distinct, they are in common in that they can guide us to find helpful condition to facilitate successful language learning. Acknowledging the contributions of each perspective and the interdisciplinarity between each field, more and more second language researchers are now trying to have a bigger lens on examining the complexities of second language acquisition.
Syntactic bootstrapping is a theory in developmental psycholinguistics and language acquisition which proposes that children learn word meanings by recognizing syntactic categories and the structure of their language. It is proposed that children have innate knowledge of the links between syntactic and semantic categories and can use these observations to make inferences about word meaning. Learning words in one's native language can be challenging because the extralinguistic context of use does not give specific enough information about word meanings. Therefore, in addition to extralinguistic cues, conclusions about syntactic categories are made which then lead to inferences about a word's meaning. This theory aims to explain the acquisition of lexical categories such as verbs, nouns, etc. and functional categories such as case markers, determiners, etc.
Ruth Berman is an Israeli linguist, Professor Emerita, Tel Aviv University, where she held the chair in “Language across the Lifespan.” Berman's research deals with the morphology, syntax, and lexicon of Modern Hebrew, first language acquisition in cross-linguistic perspective, later language development, and development of narrative and text construction abilities from early childhood across adolescence and adulthood.
Patricia J. Brooks is an American developmental psychologist. She is the director of the Language Learning Laboratory at the College of Staten Island of City University of New York and Doctoral Faculty at the Graduate Center, CUNY where she serves as the Deputy Executive Officer of the PhD program in Psychology. Brooks is also the faculty advisor of the Graduate Student Teaching Association (GSTA) of Division 2 of the American Psychological Association, The Society for the Teaching of Psychology (STP).
Hrafnhildur Hanna Ragnarsdóttir is professor emerita in Developmental and Educational Science at the University of Iceland. Her research is concerned with long-term language development and its relation to cognition, social-emotional development and literacy. Her primary research focus has been on the development of vocabulary, grammar, and narratives in early childhood and the first school years and on later language development as it appears in oral vs/written text construction and in narratives vs/expository texts from middle grades through adolescence and into adulthood.
