Visual search for specific objects, people, or activities is an important requirement in many occupational tasks, including reconnaissance and search and rescue operations. Increasing deployment of unmanned air vehicles (UAVs) has further added to the need for human operators to search for targets in still and video images provided by sensors on such vehicles. Developing expertise in such tasks typically takes extensive practice and training. The purpose of this research is to investigate the feasibility and benefits of using non-invasive transcranial direct current stimulation (tDCS) to accelerate learning on a complex visual search task simulating UAV operations. This work will be conducted in collaboration with Dr. Daniel Callan, an expert in the field of aviation research, at the Center for Information and Neural Networks (CiNET) in Osaka, Japan. Functional Magnetic Resonance Imaging (fMRI) will be used to identify specific regions of activation in frontoparietal cortical networks during task performance. These areas will then be targeted for stimulation using tDCS. Electroencephalography (EEG) data will also be collected during task performance before and after tDCS training in order to observe the effects of tDCS on neural responses related to complex visual search. The results of this study will advance theoretical knowledge of the neurocognitive mechanisms of complex visual search and identify methods for improving skill acquisition in such tasks.

对特定物体、人或活动的视觉搜索在许多职业任务中是一项重要要求，包括侦察和搜救行动。无人机(UAV)的部署越来越多，这进一步增加了人类操作员在此类车辆上的传感器提供的静止和视频图像中搜索目标的需求。开发此类任务的专业知识通常需要广泛的实践和培训。本研究的目的是探讨使用非侵入性经颅直流电刺激(TDCS)来加速学习模拟无人机操作的复杂视觉搜索任务的可行性和益处。这项工作将与位于日本大阪的信息和神经网络中心(CiNET)的航空研究领域专家Daniel Callan博士合作进行。功能磁共振成像(FMRI)将被用来识别任务执行期间额顶皮质网络中的特定激活区域。然后，这些区域将被定位为使用tdcs进行刺激。在tdcs训练前后，还将收集任务执行中的脑电(EEG)数据，以观察tdcs对复杂视觉搜索相关神经反应的影响。这项研究的结果将推进复杂视觉搜索的神经认知机制的理论知识，并确定在这类任务中提高技能获得的方法。该NSF EAPSI奖是与日本科学促进会合作资助的。该NSF EAPSI奖是与日本科学促进会合作资助的。
