The effect of various channels of feedback on the communication of information

In an experimental study, closed‐circuit television was used to test whether visual and/or audio responses from a listener increased communication accuracy. Thirty‐two dyads were drawn randomly from the male and female populations of the basic speech course at Florida State University, Analysis of covariance was used to adjust for the influence of interaction time. The findings suggested that the audio channel carried the information necessary to improve communication, and the visual channel provided auxiliary feedback which was inefficacious without the audio. A secondary finding indicated that within feedback conditions accuracy is independent of times.
