Evidence for the efficacy of the MORI technique: viewers do not notice or implicitly remember details from the alternate movie version.
The MORI technique provides a unique way to research social influences on memory. The technique allows people to watch different movies on the same screen at the same time without realizing that each of them sees something different. As a result, researchers can create a situation in which people feel as though they share an experience, but systematic differences are introduced into their memories, and the effect of those differences can be tracked through a discussion. Despite its methodological advances, the MORI technique has been met with criticism, mostly because reviewers are worried that the MORI technique might not completely block the alternate movie version from view, leading people in these studies to see their partner's version of the movie as well as their own. We addressed these concerns in two experiments. We found no evidence that subjects noticed the alternate movie version while watching a movie via the MORI technique (Experiment 1) and no evidence that subjects remembered details from the alternate movie version (Experiment 2). Taken together, the results provide support for the MORI technique as a valuable research tool.
