Abstract：
:The Self-Reference Effect (SRE), enhanced memory for self-related information, has been established in healthy young and older adults but has had limited study in age-related memory disorders such as amnestic Mild Cognitive Impairment (aMCI). Additionally, the majority of SRE studies have been conducted using trait adjective paradigms, which lack ecological validity; memory for narrative information has real-world importance and has been shown to decline in healthy aging and, to a greater extent, in aMCI. The present study investigated whether self-referential processing promotes memory for narrative information in healthy aging and, for the first time, in aMCI. The promotion of recollection (vivid re-experiencing of an event) through self-referential processing, termed the Self-Reference Recollection Effect (SRRE; Conway and Dewhurst, 1995), was also examined, as was the potential impact of material valence on the SRE. Twenty individuals with aMCI and thirty healthy older controls encoded short narratives under self-reference, semantic, and structural conditions. Memory for narrative details was subsequently tested. Results indicated a SRE for narrative information in both aMCI and healthy control groups on a recognition memory test. The SRRE was found in healthy controls and individuals with aMCI. Material valence did not impact the SRE in either group. The SRE appears to be powerful enough to circumvent loss of hippocampal function in aMCI, possibly due to the multimodal nature of narrative information. Findings from this study highlight the potential of the SRE as an effective intervention tool for improving memory for narrative information in aMCI.
