ARL-TR-3863 - Effects of Tactile, Visual, and Auditory Cues About Threat Location on Target Acquisition and Attention to Visual and Auditory Communications | U.S. Army Research Laboratory

摘要

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