Two experiments were designed to determine whether information processing in bimodal stimulation tasks was controlled by some integration mechanism or by some single channel response mechanism. The latter implies that independent decisions are made for each modality and raises some questions concerning the advisability of bisensory presentation of information. The results suggested that Ss can utilize information presented across two different modalities, but they will not do so unless there is some immediate reward. When bimodal information was redundant, Ss selectively attended to the more informative stimulus. The results have important implications for operational processes where observers must monitor both a visual and auditory display system. Modified author abstract
