Definition: A technique for studying 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.” (French et al., 2009, p. 1224).
Définition : Technique permettant d'étudier les influences sociales sur la mémoire. « Cette technique permet à des personnes de regarder simultanément des films différents sur le même écran sans se rendre compte que chacun d'entre eux voit quelque chose de distinct. Les chercheurs peuvent ainsi créer une situation dans laquelle les personnes ont l'impression de partager une expérience, mais des différences systématiques sont introduites dans leurs souvenirs, et l'effet de ces différences peut être suivi par le biais d'une discussion. » (French et al., 2009, p. 1224).
