Enhancing Lexical Competence
The Vocabulary of High Performers

Project Objective: To investigate and improve lexical competence in high-level language users.
Project Definition:
  • A lexicon is a mental dictionary. Lexical competence involves learning and using vocabulary. More than just knowledge of a large number of words, other important features of lexical competence include knowledge of:
  • multiple meanings of words, including unusual and technical meanings;
  • the various contexts in which words can be used; and
  • idioms, slang, humor, and culturally specific words.

Project Importance:
  • Professional language proficiency is not possible without high-level lexical competence. A hallmark of high-level language ability is a fully elaborated, rapidly accessible lexicon.
  • Students are taught vocabulary in the classroom
  • But they are not taught strategies for developing a high-level lexicon on the job.

Project Background:
  • Even at high levels of language proficiency, linguists often encounter unknown vocabulary.
  • Dictionaries do not always provide sufficient information to fully understand unfamiliar words.
  • For example, it may be difficult for a linguist to learn the precise meaning of a scientific term that s/he does not understand in English.

Project Products: Research Agenda: Assessing, understanding, and improving lexical competence in high-level language users.
Project Reports:
Project Activities:

    CASL will:

  • interview highly proficient linguists who work in Chinese and Arabic
  • hold a focus group with USG foreign language leaders and practitioners
  • In order to identify:

  • difficulties encountered in learning and using work-related vocabulary
  • strategies and resources used to overcome these difficulties
