Abstract
|
|
|
Objectives: This study examined Tip-of-the-Tongue (TOT) phenomenon incidence and resolving pattern differences in accordance with normal aging focusing on breakdown of phonological information production in naming processing.
Methods: TOT phenomenon was induced through naming tasks according to word category and frequency, targeting 20 young people (age 20 to 29) and 20 elderly people (age 70 and over).
Results: TOT phenomenon incidence occurred more often in the elderly than in the youth. In both groups, it occurred more often in proper nouns than in common nouns, and it occurred more often in low frequency words than in high frequency words among common nouns, where the elderly showed a greater difference. Although the TOT phenomenon occurred according to word category and frequency of common nouns in both the youth and elderly more retrieval cues were needed to resolve the TOT phenomenon in the elderly group.
Conclusion: This study empirically demonstrates that aging affects the process of phonological information production and the incidence and resolution aspects of TOT phenomenon, and it provides basic data on vocabulary characteristics which may affect the process.
