Language Processing, Cognition, and Language Use — Notes from a Lecture

Personal Background and Course Context

• Speaker introduction and current base: based up at Grafton.

• Educational background: first two degrees in speech language therapy and education at the University of Canterbury; worked as a speech language therapist in hospital settings, largely with adults with acquired communication difficulties, in Germany and the UK.

• Postgraduate work: degrees in linguistics and clinical linguistics.

• Teaching aim for the coming weeks: examine language processing and its relationship to cognition; explore how language fits into cognition and how language differences (e.g., bilingualism, multilingualism) influence perception and thought.

• Course scope: broad look at language processing from micro to macro levels (from individual sounds to words, sentences, paragraphs, and longer text); how processing relates to reading, listening, and bringing information into the brain from multiple sources.

• Theoretical focus: theories around speech perception, language understanding, and language production; sampling theories through real-world examples and recordings (audio/video with permission).

• Final focus of course: how language processing and language breakdown occur in acquired communication difficulties, with emphasis on aphasia (and note that dementia is covered in other courses).

• Real-world teaching approach: illustrate theories with demonstrations and recordings; use of a few paid or permitted recordings to illustrate language processing in practice.

• Course logistics and textbook reference:

  • Textbook: Eighth edition mentioned; page numbers provided based on this edition; content largely consistent with older editions, with some updated examples.

  • You don’t need the textbook to follow; if referencing page numbers, check the edition in use.

  • The textbook’s language chapter is a core reference across versions.

• Start-of-lecture framing: language as an impressive human achievement; ongoing debate about whether language is uniquely human; distinction between language and communication as related but not interchangeable concepts.

What is Language? Distinguishing Language from Communication

• Language as umbrella construct; communication as a key but not sole component.

• Language components are not isolated; they are integrated and combined dynamically.

• The four core components of language (two input, two output):

  • ext{Input modalities:} listening and reading.

  • These require intact sensory perception: visual processing for reading; auditory processing for listening.

  • ext{Output modalities:} speaking and writing.

  • Speaking includes sign language (signing) as a valid expressive modality; writing includes handwriting, typing, texting, and other written forms; reading includes decoding typed, handwritten, or emoji-based text.

• Note on modularity: Barry’s forthcoming lectures will address modularity in language processing and its relevance to these components.

• Relationship among components: none operate in isolation; they are integrated to enable language-based communication.

• Clarification on terminology:

  • Language vs. speech: speech is a modality of language, not the same as language itself; people conflate them, but they involve different processing and abilities.

  • Speaking is the act of conveying information (via voice, sign language, or other means); a separate output modality from the broader concept of language.

Language Acquisition and Innateness: Core Theoretical Debate

• Early development and universality: humans are thought to be born with a predisposition to acquire language; universal grammar proposed to underlie all languages.

• Universal Grammar and Language Acquisition Device (LAD):

  • Chomsky’s view: children are born with a language acquisition device that provides a basic
