Pre-Motor Response Time Benefits in Multi-Modal Displays
Abstract
The present series of experiments testes the assimilation and efficacy of purpose-created tactile messages based on five common military arm and hand signals. We compared the response times accuracy rates to these tactile representations against the comparable response to equivalent visual representations of these same messages. Results indicated that there was a performance benefit for concurrent message presentations which showed superior response items and improved accuracy rates when compared to individual presentations in either modality. Such improvement was identified as being due largely to a reduction in pre-motor response time and these improvements occurred equally in a military and non-military population. Results were no contingent upon gender of the participant. Potential reasons for this multi-modal facilitation are discussed. The novel techniques employed to measure pre-motor response inform computational neuroergonomic models for multi-modal advantages in dynamic signaling. On a practical level, these results confirm the utility of tactile messaging to augment visual messaging, especially in challenging and stressful environments where visual messaging may not always be feasible of effective.
