Children with specific language impairment exhibit weaker lexical-semantic processing, indicated by an absent N400 effect in event-related brain potentials (ERPs) during sentence comprehension.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Linguistics

Background:

  • Specific language impairment (SLI) affects language development in children.
  • Lexical-semantic processing is crucial for understanding sentence meaning.
  • Event-related brain potentials (ERPs) offer insights into real-time language processing.

Purpose of the Study:

  • To investigate lexical-semantic processing in children with SLI using ERPs.
  • To compare ERP responses to semantic violations in children with SLI and typically developing children.

Main Methods:

  • Utilized event-related brain potentials (ERPs) to measure brain activity.
  • Presented sentences with and without verb selectional restriction violations.
  • Analyzed N400 effect and late positivity components.

Main Results:

  • Typically developing children showed an N400 effect and late positivity to incorrect sentences.
  • Children with SLI lacked the N400 effect but displayed a late positivity.
  • A negativity in correct sentences for SLI group suggested weaker lexical-semantic representations.

Conclusions:

  • Children with SLI demonstrate atypical N400 responses, indicating impaired lexical-semantic processing.
  • Weakened verb representations may underlie comprehension difficulties in SLI.
  • ERPs are valuable for identifying neurophysiological differences in language disorders.
