Psycholinguistics

What it studies

Psycholinguistics is the interdisciplinary study of how people process and understand language. It covers speaking, writing, listening and reading, and how words, grammar and meaning are represented and produced. It also takes in how children acquire language and how bilingual speakers use two languages.

History and people

One common account dates psycholinguistics to the 1951 Summer Seminar in Psychology and Linguistics at Cornell and a 1953 seminar at Indiana, which produced a volume edited by Charles Osgood and Thomas Sebeok. Willem Levelt calls this the default view among psycholinguists. He also describes a late-1950s cognitive revolution, linked to George Miller and Noam Chomsky, that transformed the field, and his history covers the pre-Chomskyan era.

People and documented roles

• Willem Levelt. Author of A History of Psycholinguistics: The Pre-Chomskyan Era
  • Wrote a history of psycholinguistics that describes the 1951 and 1953 seminars as the default starting point and covers the pre-Chomskyan era. [1]
• Charles Osgood. Co-editor of the volume that followed the 1951 and 1953 seminars
  • Named by Levelt as co-editor, with Thomas Sebeok, of the volume that followed the 1951 and 1953 seminars. [1]
• Thomas Sebeok. Co-editor of the volume that followed the 1951 and 1953 seminars
  • Named by Levelt as co-editor, with Charles Osgood, of the volume that followed the 1951 and 1953 seminars. [1]
• Noam Chomsky. Named by Levelt as linked to the late-1950s cognitive revolution
  • Linked by Levelt, with George Miller, to the cognitive revolution of the late 1950s that transformed the field. [1]

The sources opened name George Miller only in passing, without a documented contribution of his own, and no founder is established. Contributors before the 1950s were not documented in the pages opened.

Dated milestones

• 1951Event. Year.Summer Seminar in Psychology and Linguistics at Cornell University, which Levelt reports as part of the default view of the field's start. [1]
• 1953Event. Year.Seminar at Indiana, reported by Levelt as part of the default view of the field's start; the seminars produced Osgood and Sebeok's volume. [1]

Methods

Researchers use brain imaging (PET and fMRI) during tasks such as semantic judgments and word generation, and run cross-linguistic studies of cue costs and cue validity. Researchers also study how caregivers' responses shape children's grammar, and use measures such as nonword repetition and sentence recall to identify specific language impairment.

Training and applications

The research is used in education, for example in work on written language among students with and without a language learning disorder, and in clinical work on language disorders such as specific language impairment and dyslexia. The sources opened for this guide describe no training route or credential specific to psycholinguistics.

Evidence behind the claims

• The research starter defines psycholinguistics as the interdisciplinary study of how humans process and understand language, and names speaking, writing, listening and reading as the language skills involved.

  What it studiesDocumented in the sourceSource: [2]Where: Definition section at the top of the research starter

• The research starter treats the representation and production of words, grammar and semantics, child language acquisition and bilingualism (second-language acquisition and code-switching) as topics of the area.

  What it studiesDocumented in the sourceSource: [2]Where: Definition, methods and Key Issues sections

• In the preface to his A History of Psycholinguistics: The Pre-Chomskyan Era, published in 2012, Willem Levelt writes that the default view among psycholinguists dates the field's start to a 1951 seminar at Cornell and a 1953 seminar at Indiana, which produced Osgood and Sebeok's volume.

  History and peopleDocumented in the sourceSource: [1]Where: Preface author and book title, Published October 25, 2012, and extract paragraph beginning 'It is, indeed, the default view'

• Levelt describes a late-1950s cognitive revolution, linked to George Miller and Noam Chomsky, that transformed the field; the book's title frames its subject as the pre-Chomskyan era.

  History and peopleDocumented in the sourceSource: [1]Where: Preface extract and book title

• The research starter reports PET and fMRI during semantic judgment and word generation tasks, cross-linguistic studies of cue costs and cue validity, caregiver responses that help shape children's grammar, and nonword repetition and sentence recall as markers of specific language impairment.

  MethodsDocumented in the sourceSource: [2]Where: Methods and Approaches section

• The research starter's Applications section describes research on written language expression among students with and without a language learning disorder, and the page discusses specific language impairment and dyslexia as language disorders.

  Training and applicationsDocumented in the sourceSource: [2]Where: Applications section

• The Linguistic Society of America states that its mission is to advance the scientific study of language.
