根据波动的任务要求和环境背景调节注意力的能力是适应行为的一个基本特征。虽然注意力处理的电生理学相关性已经在实验室中得到了广泛的研究，但对它们在更多变的生态有效条件下的展开方式知之甚少。因此，本研究采用了一个“真实世界”的脑电图设计，以调查如何注意处理不断增加的认知，运动和环境的要求。44名参与者被暴露在一个听觉古怪的任务中，同时（1）坐在实验室内一个安静的房间里，（2）在运动场周围走动，（3）在大学校园里寻找道路。在每种情况下，参与者被指示要么计数或忽略古怪的刺激。虽然在实验室和现场条件下的行为表现是相似的，但在校园条件下，奇数计数的准确性显着降低。此外，事件相关的潜在成分（不匹配负波和P3）引起的“现实世界”的设置显着不同，从实验室条件下获得的。这些研究结果表明，环境因素对注意力处理过程中的不当执行的运动和认知任务的影响，突出了自然主义的设计中纳入动态和不可预测的背景下的价值。
The capacity to regulate one’s attention in accordance with fluctuating task demands and environmental contexts is an essential feature of adaptive behavior. Although the electrophysiological correlates of attentional processing have been extensively studied in the laboratory, relatively little is known about the way they unfold under more variable, ecologically-valid conditions. Accordingly, this study employed a ‘real-world’ EEG design to investigate how attentional processing varies under increasing cognitive, motor, and environmental demands. Forty-four participants were exposed to an auditory oddball task while (1) sitting in a quiet room inside the lab, (2) walking around a sports field, and (3) wayfinding across a university campus. In each condition, participants were instructed to either count or ignore oddball stimuli. While behavioral performance was similar across the lab and field conditions, oddball count accuracy was significantly reduced in the campus condition. Moreover, event-related potential components (mismatch negativity and P3) elicited in both ‘real-world’ settings differed significantly from those obtained under laboratory conditions. These findings demonstrate the impact of environmental factors on attentional processing during simultaneously-performed motor and cognitive tasks, highlighting the value of incorporating dynamic and unpredictable contexts within naturalistic designs.
