Effects of displayed emotion on attitude and impression formation in visual speech-reading

In two experiments on visual speech-reading, with a total of 132 normal-hearing participants, the effects of displayed emotion and task specificity on speech-reading performance, on attitude toward the task and on person impression were explored, as well as associations between speech-reading performance, attitude, and person impression. The results show that displayed emotion increased speech-reading performance and attitude ratings, and that the actor was perceived as more extraverted both when displaying emotions, and when his speech was high in specificity The main conclusion was that displayed emotion enhances speech-reading performance by providing information that is useful to the speech-reader.
