This project, known as the "Auditory Principles" project, is basic research seeking to identify and model attentional principles for integrated uses of virtual audio information in Navy watchstanding operations.
Navy watchstanding operations increasingly involve environments in which operators must attend to more than one critical task display at a time. In response, the Navy is pursuing a model-based understanding of human performance in multitask settings.
Related research at NRL has demonstrated that the manner in which different types of spatialized (3D) auditory information are organized and presented can meaningfully improve associated task performance through principled management of operators’ attentional resources. Little of this work, however, has addressed multitask designs in which mixed uses of sound coexist in the same virtual listening space (e.g., voice communications and non-speech auditory cues); nor have the operational tasks that have been studied in this work been close analogues of Navy watchstanding functions. Accordingly, the primary objectives of this research are 1) to reconfigure NRL’s multimodal, multitask test bed with a suite of more Navy-relevant information tasks, 2) to study the integration of separate task-related uses of auditory information and identify principles of auditory organization that are correlated with optimal measures of attention, effort, and performance, and 3) to model explanations for, and the consequences of, these principles through cognitive models in the EPIC cognitive architecture.
