想象执行某个动作可能会诱发实际执行过该动作的错误记忆，这被称为想象膨胀效应。研究表明，动作观察（如想象）涉及动作模拟，从而在观察者中创建匹配的运动表征，我们研究了自我表现的错误记忆是否也可能因仅仅观察他人的行为而产生。在三个实验中，参与者观察了一些他们之前没有做过的动作，并进行了源记忆测试。行为观察强烈地产生了相对于控制条件的自我表现的错误记忆。这种效应的表现，我们称之为观察膨胀，揭示了日常生活中普遍存在的、以前未知的错误记忆来源。尽管在测试前立即给出了关注自我表现线索的警告或指示，并且消除了表现和观察之间的感官重叠，但这种效果仍然存在。这些发现不容易与源监控帐户相一致，但似乎适合调用人际运动模拟的帐户。
Imagining performing an action can induce false memories of having actually performed it-this is referred to as the imagination-inflation effect. Drawing on research suggesting that action observation-like imagination-involves action simulation, and thus creates matching motor representations in observers, we examined whether false memories of self-performance can also result from merely observing another person's actions. In three experiments, participants observed actions, some of which they had not performed earlier, and took a source-memory test. Action observation robustly produced false memories of self-performance relative to control conditions. The demonstration of this effect, which we refer to as observation inflation, reveals a previously unknown source of false memories that is ubiquitous in everyday life. The effect persisted despite warnings or instructions to focus on self-performance cues given immediately before the test, and despite elimination of sensory overlap between performance and observation. The findings are not easily reconciled with a source-monitoring account but appear to fit an account invoking interpersonal motor simulation.
