Area of Science:

  • Linguistics
  • Developmental Psychology
  • Cognitive Science

Background:

  • Language acquisition is influenced by both environmental input and innate biological factors.
  • Children's linguistic experience alone does not fully explain the grammars they acquire.
  • Endogenous constraints, originating from the biology of the mind, are crucial for language development.

Purpose of the Study:

  • To explore the interplay between language input and innateness in child language acquisition.
  • To advocate for explicit theories of acquisition that incorporate innate constraints.
  • To emphasize the need for a robust theory of language input, including identifying invariant properties.

Main Methods:

  • Theoretical analysis of language acquisition principles.

Related Experiment Videos

  • Examination of the relationship between linguistic input and endogenous constraints.
  • Discussion of the empirical testability of innateness assumptions.

    • Main Results:

    • Language input and innate factors are complementary in language acquisition.
    • Innate constraints are necessary to account for underdetermination by input.
    • Overly strong innateness assumptions may lack empirical falsifiability.

    Conclusions:

    • Explicitly formulating theories of acquisition that include innateness is beneficial.
    • Developing a theory of language input, focusing on invariants, is essential.
    • Combining input theory with endstate linguistic theory can reveal underlying cognitive properties for language acquisition.
