Summary

Individuals with left-hemisphere damage (LHD) and right-hemisphere damage (RHD) access multiple word meanings similarly to controls. Findings partially support the suppression deficit hypothesis but not coarse semantic coding.

Area of Science:

  • Neuroscience
  • Psycholinguistics
  • Cognitive Psychology

Background:

  • Understanding how brain damage affects semantic processing is crucial for rehabilitation.
  • Previous theories, like the suppression deficit and coarse semantic coding hypotheses, offer explanations for linguistic deficits after right-hemisphere damage.

Purpose of the Study:

  • To investigate semantic ambiguity resolution in individuals with left-hemisphere damage (LHD) and right-hemisphere damage (RHD) compared to controls.
  • To test predictions of the suppression deficit and coarse semantic coding hypotheses.

Main Methods:

  • An auditory semantic priming paradigm was employed.
  • Participants included LHD non-fluent aphasic, RHD, and normal control groups.
  • Ambiguous words (homonyms, metonymies, metaphors) were presented as primes, followed by related or unrelated target words at short (100 ms) and long (1000 ms) inter-stimulus intervals (ISIs).

Main Results:

  • No significant group differences were observed in accessing word meanings.
  • Both LHD and RHD groups, like controls, showed facilitation for dominant and subordinate meanings of homonyms and metonymies.
  • For metaphors, only dominant meanings were facilitated across all groups and ISIs.

Conclusions:

  • Focal LH or RH damage does not impair the ability to access multiple meanings of ambiguous words at the single-word level.
  • Findings offer partial support for the suppression deficit hypothesis and no support for the coarse semantic coding hypothesis.
  • Patients with aphasia demonstrate semantic processing abilities comparable to normal controls in this context.
