Semantic Paraphasia

meaning of the word is related to that of the intended word

6 different types:

 

  • Coordinate semantic paraphasias  – same category (tiger for lion)
  • Associate semantic paraphasias – related but not the same category (shoe for foot)
  • Superordinate semantic paraphasias – replaces specific with generalized (fruit for pear)
  • Subordinate semantic paraphasias – replace target word with one that is more specific (rose for flower)
  • Part-whole semantic paraphasias – replace the whole with the part (finger for hand) or part with the whole (leg for foot)
  • Visual semantic paraphasia – replace word with another word that shares same visual features (knife for nail)
