An experimenter presented familiar and bizarre action statements (e.g., "Rest on the fire hydrant" vs. "Shake hands with the fire hydrant") to a participant and confederate during a campus walk. They watched the experimenter perform half the actions and imagined the experimenter performing the other half. One day later, they took a second walk where actions were only imagined. Some actions from the first walk were repeated, and new actions were added. Two weeks later, the participant and confederate collaboratively recalled whether specific actions were presented in the first walk and, if so, whether they were imagined or performed. For different actions, the confederate was accurate, was inaccurate, or provided no information. When later tested individually, participants demonstrated imagination inflation by falsely remembering familiar and bizarre actions as performed on the first walk that were merely imagined on the second. These memory errors were greatly reduced if the confederate was accurate during collaborative recall.
在一次校园散步期间，一名实验者向一名参与者和一名同谋展示了常见和奇异的动作陈述（例如，“靠在消防栓上休息”与“和消防栓握手”）。他们看着实验者执行一半的动作，并想象实验者执行另一半动作。一天后，他们再次散步，此时动作仅靠想象。第一次散步中的一些动作被重复，并且添加了新的动作。两周后，参与者和同谋共同回忆第一次散步中是否展示了特定动作，如果展示了，这些动作是想象的还是执行的。对于不同的动作，同谋的回答要么准确，要么不准确，要么没有提供信息。当后来单独测试时，参与者表现出想象膨胀，错误地将在第二次散步中只是想象而在第一次散步中实际执行的常见和奇异动作回忆为实际执行过的。如果同谋在共同回忆期间回答准确，这些记忆错误会大大减少。
