Abstract: This study examined the effects of tactile, visual, and auditory (spatial language and three-dimensional [3-D] audio) cues about threat location on target acquisition and the recall of information presented in visual and auditory communications. On average, participants hit 98% of the targets presented when cued about the location of targets compared to 64% in a baseline condition (no cues). When target location cues were provided, time to first shot was an average 26% faster; 23% more information was recalled from the auditory and visual communications, and overall workload scores were 17% lower. On average, time to first shot in the visual and spatial language modes was 13% faster than in the tactile condition and 26% faster than in the 3-D audio mode. Overall workload scores were an average 14% higher in the 3-D audio mode than in the other conditions in which target location cues were provided. Communications modality did not have a significant effect on either the amount of information recalled from the communications or on target acquisition. No interactions were found between communications modality and cue condition. However, on average, 10% more information was recalled from communications when target location cues were provided in the visual mode than in the other cue conditions.
