Audio-Visual Redundancy and TV News Recall

Abstract

This experimental study examines the effects of audio and visual redundancy on recall and story understanding in television news. College students viewed a series of voice-over news stories that varied in the amount of redundancy between the two channels and then responded to both auditory and visual recall measures. The results show higher auditory recall and story understanding in the high-redundancy condition than in the lower redundancy conditions. Visual recall shows the reverse pattern with higher recall scores in the lower redundancy conditions than in the high-redundancy condition.
