Qualitative effects of rehearsal on memories for perceived and imagined complex events.

Three experiments explored the effects of rehearsal and the passage of time on qualitative characteristics of memories for perceived and imagined complex events. Subjects thought or talked about events, focusing on either the perceptual (e.g., colors, sounds) or apperceptive (e.g., thoughts, feelings) aspects of the events (Experiment 1). Thinking about apperceptive aspects of events decreased the salience of context and sensory characteristics of memories and made memories for perceived and imagined events seem more similar in the subjective amounts of thoughts and feelings included in the memories. When the aspects of events subjects thought about were unspecified, thinking about events primarily affected rated clarity (Experiment 2). The clarity of imagined events was more affected than was the clarity of perceived events by whether the memories had been rated previously (Experiments 1 & 3). Over 24 hrs, clarity and sensory ratings decreased more for imagined than for perceived events (Experiment 3). Implications for reality monitoring (M. K. Johnson and C. L. Raye [see PA, Vol 65:6694]) are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
