An aphasic individual accurately produced consonantal inflections but omitted syllabic ones, like saying "bench" instead of "benches." This highlights specific challenges in morpho-phonological speech production.

Area of Science:

  • Linguistics
  • Neurolinguistics
  • Speech Production

Background:

  • Aphasia can manifest in various speech production deficits.
  • Morphological inflections have different phonological forms (allomorphs).

Observation:

  • An English-speaking aphasic individual (TB) demonstrated selective difficulty with syllabic inflections (-/əz/, -/əd/).
  • TB accurately produced consonantal inflections (-/s/, -/z/, -/d/, -/t/) but omitted syllabic ones.

Findings:

  • Control tests excluded syntactic, phonological, or articulatory deficits.
  • The difficulties were localized to morpho-phonological mechanisms adapting morphology to word phonology.

Implications:

  • Provides insight into the lexicon's encoding of morphological elements.
