这项研究利用功能性磁共振成像技术确定了与听觉警觉性任务相关的大脑激活。我们创建了听觉连续表现测试（CPTs），通过增加工作记忆和干扰过滤需求，使要求高的任务（工作记忆任务）比简单的警觉性任务更难。两组正常男性控制组在工作记忆CPT测试中的表现明显低于警觉性测试。与警觉性任务相比，工作记忆任务的执行在外侧和内侧前额叶皮层、中央前皮层、颞叶（包括岛和海马）、顶枕皮层、扣带回、丘脑和上丘产生了显著的信号变化。表现和激活程度与对智商的估计有关。进一步的研究应阐明工作记忆和干扰过滤对激活网络的贡献。（PsycINFO数据库记录(c) 2016 APA，版权所有）
This study identified the brain activations associated with auditory vigilance tasks, using functional magnetic resonance imaging. We created auditory continuous performance tests (CPTs) in which a demanding task (working memory task) was made more difficult than a simple vigilance task by increasing working memory and interference filtering demands. Two cohorts of normal male controls performed significantly worse on the working memory CPT than on the vigilance task. Compared to the vigilance task, performance of the working memory task produced significant signal change in lateral and medial prefrontal cortex, precentral cortex, temporal lobe, including insula and hippocampus, parietal-occipital cortex, cingulate, thalamus, and superior colliculus. Performance and degree of activation was associated with an estimate of IQ. Further research should clarify the contributions of working memory and interference filtering to the activated network.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
