Object naming in aphasia is influenced by visual complexity, familiarity, age of acquisition, and word frequency. These factors predict naming accuracy in most patients, impacting object recognition and name retrieval.

Area of Science:

  • Neuroscience
  • Psycholinguistics
  • Cognitive Psychology

Background:

  • Aphasia, a language disorder post-brain damage, often impairs object naming.
  • Understanding factors influencing naming accuracy is crucial for diagnosis and rehabilitation.

Purpose of the Study:

  • To investigate the effects of object characteristics and linguistic variables on object naming accuracy in Spanish-speaking aphasic patients.
  • To determine which factors best predict naming performance at both group and individual levels.

Main Methods:

  • Sixteen Spanish aphasic patients participated in object naming tasks across three sessions.
  • Multiple regression analyses were employed to assess the impact of visual complexity, object familiarity, age of acquisition, and word frequency on naming accuracy.

Main Results:

  • Object naming was significantly affected by visual complexity, object familiarity, age of acquisition, and word frequency in the group analysis.
  • These variables collectively predicted naming accuracy in 15 out of 16 individual patients.
  • Age of acquisition, word frequency, and object familiarity were the most influential predictors across patients.

Conclusions:

  • Object recognition appears influenced by visual complexity and familiarity, while name retrieval is affected by word frequency.
  • Age of acquisition may impact both recognition and retrieval stages, explaining its broad influence.
  • These findings offer insights into the cognitive processes underlying object naming in aphasia.
