  • Title: Age-related differences in word-retrieval but not in meaning generation.
    Author: Kavé G, Mashal N.
    Journal: Neuropsychol Dev Cogn B Aging Neuropsychol Cogn; 2012; 19(4):515-29. PubMed ID: 22221146.
    Abstract:
    This study examines age-associated changes in retrieval on a picture-naming task, phonemic and semantic fluency tasks, and the Homophone Meaning Generation Test (HMGT). The sample included 152 Hebrew-speaking adults, half young (mean age 22.75) and half old (mean age 76.05). Groups differed on the picture-naming task and on both verbal fluency tasks, but not on the HMGT. Age explained a greater share of the variance than did education level on these three tests, whereas the opposite pattern of results was seen on the HMGT. We suggest that age-related word finding difficulties are attenuated when performance allows for semantic rather than phonological access.
