| Summary: | The problem of this experimental study is to determine to what extent visual information may dominate over audio information. Additionally, the experimental design addresses problems with previous research in this area and emphasizes simplified approaches to the study of channel condition effects. The study does not include investigations of learning theory or short-term memory, but processes of listening and long-term memory are incorporated into the design. A stimulus of sound effects and slides was utilized in one audio and two audio-visual channel conditions, and results showed a high recall among all subjects in all three conditions. The study concludes that channel condition has little effect at low levels of information.
