Population momentum is a consequence of the demographic transition.Population momentum explains why a population will continue to grow even if the fertility rate declines. . Population momentum occurs because it is not only the number of children per woman that determine population growth, but also the number of women in reproductive
The Competition Model is a psycholinguistic theory of language acquisition and sentence processing, developed by Elizabeth Bates and Brian MacWhinney (1982). [1] The claim in MacWhinney, Bates, and Kliegl (1984) [2] is that "the forms of natural languages are created, governed, constrained, acquired, and used in the service of communicative functions."
e. Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language. In other words, it is how human beings gain the ability to be aware of language, to understand it, and to produce and use words and sentences to communicate. Language acquisition involves structures, rules, and representation.
In sociolinguistics, language planning (also known as language engineering) is a deliberate effort to influence the function, structure or acquisition of languages or language varieties within a speech community. [1] Robert L. Cooper (1989) defines language planning as "the activity of preparing a normative orthography, grammar, and dictionary ...
Statistical language acquisition, a branch of developmental psycholinguistics, studies the process by which humans develop the ability to perceive, produce, comprehend, and communicate with natural language in all of its aspects (phonological, syntactic, lexical, morphological, semantic) through the use of general learning mechanisms operating on statistical patterns in the linguistic input.
Linguistic demography is the statistical study of languages among all populations. Estimating the number of speakers of a given language is not straightforward, and various estimates may diverge considerably. This is first of all due to the question of defining "language" vs. "dialect". Identification of varieties as a single language or as ...
Theories of second-language acquisition. 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 ...
The basis of Noam Chomsky's linguistic theory lies in biolinguistics, the linguistic school that holds that the principles underpinning the structure of language are biologically preset in the human mind and hence genetically inherited. [2] He argues that all humans share the same underlying linguistic structure, irrespective of sociocultural ...
