Area of Science:

  • Neuroscience
  • Linguistics
  • Speech-Language Pathology

Background:

  • Anomic aphasia and acquired alexia impair reading abilities, particularly in text comprehension.
  • Patients often exhibit slow, effortful reading with errors like functor substitutions.

Observation:

  • Single-word reading was accurate, but text reading was slow and error-prone.
  • Pre-treatment word reading times showed effects of grammatical class and word length.

Findings:

  • A two-phase treatment protocol (multiple oral rereading and phrase-formatted text) improved text reading rates.
  • Comprehension was maintained post-treatment.
  • Post-treatment word reading times eliminated grammatical class and word-length effects.

Implications:

  • This treatment approach enhances word form access, particularly for functors.
  • It offers a viable strategy for improving reading in individuals with aphasia and alexia.
  • Findings suggest plasticity in reading networks following targeted intervention.
