Summary:
This study examined bimodal information processing in the identification of radar signals in a realistic environment. Research suggests that the identification of signals should be faster, more accurate, and visually biased when targets contain redundant components compared to visual-only or auditory-only targets. Experiment 1 compared reaction times under three conditions: auditory-modality, visual-modality, and dual-modality. The results indicated that dual-modality targets produced the fastest reaction times and performance in the auditory-modality was significantly slower than the others (p < .01). Results concerning accuracy were inconclusive. Experiment 2 measured how quickly and how accurately participants could identify dual-modality target signals under matched or mismatched conditions. The results of Experiment 2 indicated strong support for a visual bias (p < .01).
