Fade In, Fade Out: Do Shifts in Visual Perspective Predict the Consistency of Real-World Memories?
研究发现，回忆时视觉视角（第一人称或旁观者）随时间变化越大，记忆一致性越差，尤其影响情绪细节，对理解日常记忆和目击证词有参考价值。
Memories of our personal past are not exact accounts of what occurred. Instead, memory reconstructs the past in adaptive—though not always faithful—ways. Using a naturalistic design, we asked how the visual perspective adopted in the mind’s eye when recalling the past—namely, an “own eyes” versus “observer” perspective—relates to the stability of autobiographical memories. We hypothesized that changes in visual perspective over time would predict poorer consistency of memories. Young adults ( N = 178) rated the phenomenology of and freely recalled self-selected memories of everyday events at two time points (10 weeks apart). Multilevel linear modeling revealed, as expected, that greater shifts in visual perspective over time predicted lower memory consistency, particularly for emotional details. Our results offer insight into the factors that predict the fidelity of memories for everyday events. Moreover, our results may elucidate new metrics that are useful in interpreting eyewitness testimony or experiences relayed in clinical contexts.
