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.
