Language Development

365
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Language and Cognition

346
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Summary

Developing small corpora for child language acquisition research is challenging. A non-sequential sampling protocol for small corpus development (NSP-SCD) effectively approximates larger corpora, aiding studies in under-resourced languages.

Area of Science:

  • Psycholinguistics
  • Corpus Linguistics
  • Child Language Acquisition

Background:

  • Systematic psycholinguistic research requires child-directed print corpora, which are scarce for understudied languages.
  • Researchers often rely on manual tagging due to the lack of automated parsers for these languages.
  • Small corpora are a potential solution, but their robustness is not well-understood.

Purpose of the Study:

  • To evaluate the effectiveness of a non-sequential sampling protocol for small corpus development (NSP-SCD).
  • To assess the lexical and orthographic properties of a small corpus created using NSP-SCD.
  • To compare the efficiency of NSP-SCD with traditional sampling methods for small corpus construction.

Main Methods:

  • A small corpus (17,584 words) was created using NSP-SCD from a larger corpus (150,595 words) of children's books (ages 3-10).
  • Cross-corpora and within-corpus analyses were performed to compare the small and large corpora.
  • Lexical diversity, orthographic representation, word length, and psycholinguistic complexity were analyzed.
  • Robustness was checked by comparing NSP-SCD with a same-sized corpus from a limited number of books.

Main Results:

  • The small corpus approximated the lexical and orthographic diversity of the larger corpus.
  • The small corpus was equivalent to the larger corpus in orthographic representation and word length.
  • Psycholinguistic complexity varied by book level and part of speech.
  • NSP-SCD was more efficient for lexical diversity than a same-sized corpus from few books.

Conclusions:

  • Non-sequential sampling protocol for small corpus development (NSP-SCD) is a promising method for creating representative small corpora.
  • Stratified sampling from books by level enhances corpus statistics, making them approximate larger corpora.
  • This protocol can advance child language acquisition research in understudied languages by enabling more robust corpus creation.
