Objective-The ability to imagine an elaborative event from a personal perspective relies on a number of cognitive processes that may potentially enhance subsequent memory for the event, including visual imagery, semantic elaboration, emotional processing, and self-referential processing. In an effort to find a novel strategy for enhancing memory in memory-impaired individuals with neurological damage, the present study investigated the mnemonic benefit of a method we refer to as "self-imagining" -or the imagining of an event from a realistic, personal perspective.Method-Fourteen individuals with neurologically-based memory deficits and fourteen healthy control participants intentionally encoded neutral and emotional sentences under three instructions: structural-baseline processing, semantic processing, and self-imagining.Results-Findings revealed a robust "self-imagination effect" as self-imagination enhanced recognition memory relative to deep semantic elaboration in both memory-impaired individuals, F (1, 13) = 32.11, p < .001, η 2 = .71, and healthy controls, F (1, 13) = 5.57, p < .05, η 2 = .30. In addition, results indicated that mnemonic benefits of self-imagination were not limited by severity of the memory disorder nor were they related to self-reported vividness of visual imagery, semantic processing, or emotional content of the materials.Conclusions-The findings suggest that the self-imagination effect may depend on unique mnemonic mechanisms possibly related to self-referential processing, and that imagining an event from a personal perspective makes that event particularly memorable even for those individuals with severe memory deficits. Self-imagining may thus provide an effective rehabilitation strategy for individuals with memory impairment.
KeywordsImagination; Self; Memory disorders; Memory rehabilitation; Episodic memory Imagining an elaborative event from a personal perspective is a cognitive ability thought to involve numerous component processes. For example, if asked to imagine that you are at a college basketball game with a friend, you will presumably construct the spatial context of a basketball arena, place yourself somewhere in the context, and simulate watching the game with your friend. To do this, you will likely recruit cognitive processes such as visual (Rubin, Corresponding author: Matthew D. Grilli. Department of Psychology, University of Arizona, 1503 E. University Blvd, P.O.
