False memories can be created by a simple priming manipulation (the Deese-Roediger-McDermott procedure). This phenomenon operates via the strong associative character of declarative memory. If it is true that that content knowledge plays an important role in presence (As some have argued), then a presence experience could prime a subject and create false memories. We tested this notion by repeatedly exposing 47 subjects to a themed VE, and after a 72 hour delay, testing their recall of VE content. As predicted, subjects tended to have higher false memory rates (of VE content) than chance levels for moderately specific false memory items, and lower than chance level rates of false memory for highly specific items. Furthermore, engagement and naturalness (as measured with the ITC-SOPI) predicted false memory rates. These findings support the notion that subjects’ semantic knowledge plays a role in the presence experience.
