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.
Psycholinguistics is concerned with the cognitive faculties and processes that are necessary to produce the grammatical constructions of language. It is also concerned with the perception of these constructions by a listener.
Initial forays into psycholinguistics were in the philosophical and educational fields, due mainly to their location in departments other than applied sciences (e.g., cohesive data on how the human brain functioned). Modern research makes use of biology, neuroscience, cognitive science, linguistics, and information science to study how the mind-brain processes language, and less so the known processes of social sciences, human development, communication theories, and infant development, among others.
There are several subdisciplines with non-invasive techniques for studying the neurological workings of the brain. For example, neurolinguistics has become a field in its own right, and developmental psycholinguistics, as a branch of psycholinguistics, concerns itself with a child's ability to learn language.
Areas of study
Psycholinguistics is an interdisciplinary field that consists of researchers from a variety of different backgrounds, including psychology, cognitive science, linguistics, speech and language pathology, and discourse analysis. Psycholinguists study how people acquire and use language, according to the following main areas:
language acquisition: how do children acquire language? language comprehension: how do people comprehend language? language production: how do people produce language? second language acquisition: how do people who already know one language acquire another one?
A researcher interested in language comprehension may study word recognition during reading, to examine the processes involved in the extraction of orthographic, morphological, phonological, and semantic information from patterns in printed text. A researcher interested in language production might study how words are prepared to be spoken starting from the conceptual or semantic level (this concerns connotation, and possibly can be examined through the conceptual framework concerned with the semantic differential). Developmental psycholinguists study infants' and children's ability to learn and process language.
Psycholinguistics further divide their studies according to the different components that make up human language.
Linguistics-related areas include: Phonetics and phonology are the study of speech sounds. Within psycholinguistics, research focuses on how the brain processes and understands these sounds. Morphology is the study of word structures, especially between related words (such as dog and dogs) and the formation of words based on rules (such as plural formation). Syntax is the study of how words are combined to form sentences. Semantics deals with the meaning of words and sentences. Where syntax is concerned with the formal structure of sentences, semantics deals with the actual meaning of sentences. Pragmatics is concerned with the role of context in the interpretation of meaning.
History
In seeking to understand the properties of language acquisition, psycholinguistics has roots in debates regarding innate versus acquired behaviors (both in biology and psychology). For some time, the concept of an innate trait was something that was not recognized in studying the psychology of the individual. However, with the redefinition of innateness as time progressed, behaviors considered innate could once again be analyzed as behaviors that interacted with the psychological aspect of an individual. After the diminished popularity of the behaviorist model, ethology reemerged as a leading train of thought within psychology, allowing the subject of language, an innate human behavior, to be examined once more within the scope of psychology.
Origin of "psycholinguistics" The theoretical framework for psycholinguistics began to be developed before the end of the 19th century as the "Psychology of Language". The work of Edward Thorndike and Frederic Bartlett laid the foundations of what would come to be known as the science of psycholinguistics. In 1936 Jacob Kantor, a prominent psychologist at the time, used the term "psycholinguistic" as a description within his book An Objective Psychology of Grammar.
