Do video clips add more value than audio clips? Presenting industrial research and development results using multimedia

Abstract

It was hypothesised that in multimedia information applications a visual component can add value to otherwise audio-only clips. Subjects rated clips used in published CD-ROMs and how much they remembered was also tested. In one set of clips, the visual component was removed, in a second the audio was removed and a third set was unedited. The experiment was run three times, on different groups, to check replicability. For all groups, clips with a visual component as well as audio were judged to contain more information and to be more interesting than audioonly clips. There was also some evidence that the visual component can increase subjects' confidence in what they can remember. Other expected effects were not observed in every group in which they were tested. It is speculated that training in media literacy may help developers to use the visual component more effectively.

Avenue T: using film asentréein teaching about transgender

“…the transgender concept, what is often a lifelong pattern of gender atypicality among persons who may identify as transgender, how an organic progression of transgenderism affects family systems) in a medium that would not be perceived as threatening, hyperbolic, or politically biased. Prior studies have included audio or visual media materials as experimental stimuli because they meet these criteria (Chaiken and Eagly 1983;Christie and Collyer 2008;Furnham, De-Siena, and Gunter 2002;Soble, Spanierman, and Liao 2011;Walters 1994). A television news show filmed and distributed in the USA dedicated a one-hour news programme to transgenderism.…”

Is perception of quality more important than technical quality in patient video cases?

“…The potential benefits of patient video cases (PVCs) are being increasingly realised [ 1 ], with a survey of children’s hospitals in North America and the UK finding that video recordings of clinical interactions and patient signs are relatively common [ 2 ]. Video can be a powerful tool as the addition of video to audio clips have been demonstrated to have large effects on the recall of the content of the cases, both objectively and subjectively [ 3 ]. The knowledge and learning obtained from PVCs is dependent on a number of factors that have yet to be determined.…”
