Foundations of Human Language

  • Universal Grammar Theory: Introduced by Noam Chomsky in the 1960s.

    • Suggests that the ability to acquire language is innate to humans.

    • Proposes all human languages share a common underlying structure.

Key Concepts

  • Innateness Hypothesis:

    • States that humans are born with an inherent understanding of the fundamental principles of grammar.

    • Enables children to learn complex language structures rapidly and effortlessly.

  • Language Acquisition Device (LAD):

    • Hypothetical module in the brain responsible for language acquisition.

  • Principles and Parameters:

    • Framework of UG consisting of universal principles and language-specific parameters.

Principles and Parameters

Principles

  • Fundamental rules consistent across all human languages.

    • Example: All languages require a subject and a predicate.

      • Illustration: "The cat sleeps" (Subject: The cat, Predicate: sleeps).

Parameters

  • Settings within UG that vary across languages influencing specific grammatical rules.

  • Word Order Variations:

    • SVO in English.

    • SOV in Japanese.

    • Example Illustrations:

      • (2) She is eating an apple. (English, SVO)

      • (3) O bir elma yi-yor (Turkish, SOV).

Examples of Parameters

  • SVO (English):

    • (4) She reads books.

  • SOV (Japanese):

    • (5) Kanojo wa hon o yomu.

  • VSO (Arabic):

    • (6) yaqraʔ al-walad-u al-Kitab-a.

    • Translation: The boy reads the book.

Syntax and Structure

  • Syntax: Rules governing sentence structure and combining words into phrases.

  • Deep Structure vs. Surface Structure:

    • Deep Structure: Underlying representation with syntactic relations.

      • Example: "The cat chased the dog."

    • Surface Structure: Concrete form expressed in speech/writing.

      • Example Variations: "The dog was chased by the cat." vs. "The cat chased the dog."

Language Acquisition Device (LAD)

  • An innate mechanism enabling language acquisition.

  • Utilizes UG principles to interpret/generate linguistic structures.

  • Facilitates rapid language learning by adapting to specific linguistic environments.

Language Acquisition

Critical Period Hypothesis (CPH)

  • Definition: Proposes a specific timeframe for optimal language acquisition, primarily before puberty.

  • Children are more likely to become fluent in a language if learned early.

  • Case Study: Genie, isolated until age 13, struggled significantly with language acquisition despite training.

Theoretical Contributions

Noam Chomsky’s Theories

  • Generative Grammar: Ability to generate grammatical sentences is inherent.

  • Minimalist Program: Attempts to explain UG properties with basic principles, identifying universal language characteristics.

Poverty of the Stimulus (Evidence)

  • Suggests linguistic input is insufficient to explain language complexity, implying innate knowledge.

  • Example: Children produce complex sentences they’ve never heard, indicating they apply innate grammatical rules.

  • Cross-Linguistic Similarities: Despite surface differences, all languages share fundamental features, like noun phrases and verb phrases, supporting UG.
