Imagery perspective and source monitoring in imagination inflation.

The present experiments suggest that imagery perspective--first person (own) versus third person (observer's)--influences source-monitoring judgments. Imagination inflation (Garry, Manning, Loftus, & Sherman, 1996) occurs when imaginary experience with events is mistaken for real experience. In Experiment 1, the perspective used to visualize real past events depended on memory test wording ("remember doing?" vs. "happened to you?"). Experiment 2 manipulated the perspective used to visually imagine counterfactual events and showed that the effect on imagination inflation depended on memory test wording. Imagination inflation was most likely when memory test wording encouraged participants to visualize real events from the same perspective as they had used to imagine counterfactual ones. Imagination inflation may result not simply from having created imaginary representations of events, but also from having created representations that match the decision criteria used in source monitoring.
