The Influence of Time Delay and Serial Position on Story Retelling Abilities in the Elderly with Subjective Memory Impairments

Purpose: As the conversion rate of degenerative dementia in the elderly with subjective memory impairments (SMI) has been reported to be high, the attempts to examine their cognitive-linguistic abilities and compare with normal elderly (NE) have drawn attention. This study has executed the story retelling task, frequently used as a subcategory of memory test, to NE and elderly with SMI, and conducted a comparative analysis of the performance according to time delay and serial position. Methods: The stories composed of a total of 18 information units (IU) were told to a total of 80 elderly (NE = 40, SMI = 40), and immediate and delayed recall was conducted. Results: The IU recall rate (%) of SMI was significantly lower than that of NE (F = 116.482, p < 0.001), and the IU recall rate (%) was significantly lower for delayed recall than for immediate recall (F = 9.460, p < 0.01), and the intermediate position showed a significantly higher IU recall rate (%) compared to the primacy position (F = 4.138, p < 0.05). Conclusion: SMI, unlike NE, showed difficulty in using rehearsal strategy or storing new information, which indicates that some parts of the meta-cognitive function can have negative influences in SMI stages as well.
