Language Development

1.1K
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...

Summary

The TRACE model explains infant word recognition by simulating how infants process mispronunciations and learn words. It reconciles conflicting findings on consonant and vowel roles in early lexical acquisition.

Area of Science:

  • Cognitive Science
  • Developmental Psychology
  • Computational Linguistics

Background:

  • Infant word recognition is crucial for language development.
  • Existing theories offer different explanations for how infants recognize words.
  • Conflicting findings exist regarding the role of consonants versus vowels in early word learning.

Purpose of the Study:

  • To provide a unified theoretical framework for infant word recognition using the TRACE model.
  • To simulate and reconcile conflicting findings in infant speech perception literature.
  • To evaluate existing accounts of infant word recognition.

Main Methods:

  • Simulations using the TRACE model of speech perception.
  • Reconciling findings on consonant/vowel roles in lexical acquisition.
  • Simulating infants' sensitivity to mispronunciations and phonological neighborhood effects.

Main Results:

  • TRACE reconciled findings on consonant pre-eminence and symmetrical sensitivity to mispronunciations.
  • TRACE required reduced inhibition to simulate graded sensitivity to mispronunciations.
  • TRACE explained phonological neighborhood effects through mispronunciation processing.

Conclusions:

  • The TRACE model offers a unified framework for understanding infant word recognition.
  • Vocabulary structure and content influence infant word recognition in an experience-dependent manner.
  • There is continuity in lexical development processes during the second year of life.
