Using signal detection methods, this study found participants were better able to discriminate information from news stories with redundant visuals than from news stories with dissonant visuals.This finding, along with the absence of memory decision-criterion differences between the redundant and dissonant conditions, is further evidence that the robust audio/video redundancy effect in the literature reflects differences of memory strength and not simply a shift in decision criterion. More interesting, there were no significant differences when examining correct recognitions only, further pointing to the need for signal detection methods in media memory studies.
