Human Integration of Concurrent Audio and Visual Message
Two experiments were performed involving the concurrent presentation of two messages, one auditory and one visual, to human subjects. These messages were followed by a question requiring information from them. The results indicated that biomodally-presented information can be integrated for decision making. There was, however, no evidence of an advantage to bimodal presentation as a means of unburdening an overloaded sense. The implications of the results for displays and communications in complex control centers are discussed and directions for future research are suggested.
