Summary

Semantic satiation, the repeated exposure to a word, may hinder the brain's ability to resolve lexical ambiguity. This effect was observed when only context-appropriate meanings were repeatedly presented.

Area of Science:

  • Cognitive Psychology
  • Psycholinguistics
  • Neuroscience

Background:

  • Lexical ambiguity resolution is a fundamental cognitive process.
  • Semantic satiation is a phenomenon where repeated exposure to a word leads to a temporary reduction in its meaning's accessibility.
  • Understanding how these processes interact is crucial for cognitive models of language.

Purpose of the Study:

  • To investigate the impact of semantic satiation on the resolution of lexical ambiguity.
  • To determine if repeated exposure to a homograph's context-appropriate meaning affects subsequent ambiguity resolution.

Main Methods:

  • Participants completed relatedness judgments on word triads including a homograph.
  • Experiment 1 intermixed concordant, discordant, and neutral trials.
  • Experiment 2 used only concordant and neutral trials to examine semantic satiation effects.

Main Results:

  • Experiment 1 showed no evidence of semantic satiation when trial types were mixed.
  • Experiment 2 demonstrated semantic satiation in the concordant condition.
  • Semantic satiation of a homograph's dominant meaning appeared to impede ambiguity resolution.

Conclusions:

  • Semantic satiation can interfere with lexical ambiguity resolution.
  • The presentation context of trials influences the occurrence of semantic satiation effects.
  • Findings suggest that repeated activation of a specific meaning can impair the processing of ambiguous words.
