College students with higher lexical familiarity demonstrated faster and more accurate language processing. This study highlights the link between word familiarity and cognitive efficiency in reading and decision-making tasks.

Area of Science:

  • Cognitive Psychology
  • Psycholinguistics
  • Neuroscience

Background:

  • Individual differences in language processing are significant.
  • Lexical familiarity, or how well individuals know words, is a key factor.
  • Understanding processing efficiency is crucial for explaining these differences.

Purpose of the Study:

  • To investigate if college students grouped by lexical familiarity differ in cognitive processing.
  • To examine differences in visual word naming, lexical decision, and semantic categorization.
  • To explore the relationship between processing efficiency and working memory in language.

Main Methods:

  • College students were divided into high and low familiarity groups based on word ratings, language experience, and vocabulary tests.

  • Three experiments assessed visual word naming speed, lexical decision accuracy, and semantic categorization.
  • Performance metrics included reaction time and accuracy.
  • Main Results:

    • Students in the high familiarity group were consistently faster at naming visually presented words.
    • The high familiarity group also showed superior speed and accuracy in difficult lexical decisions.
    • They were more accurate in rejecting homophone foils during semantic categorization tasks.

    Conclusions:

    • Differences in lexical familiarity correlate with differences in cognitive processing efficiency.
    • Individuals with greater word familiarity exhibit enhanced language processing capabilities.
    • These findings contribute to understanding individual variations in language processing and working memory.
