In recent years, three attentional networks have been defined in anatomical and functional terms. These functions involve alerting, orienting, and executive attention. Reaction time measures can be used to quantify the processing efficiency within each of these three networks. The Attention Network Test (ANT) is designed to evaluate alerting, orienting, and executive attention within a single 30-min testing session that can be easily performed by children, patients, and monkeys. A study with 40 normal adult subjects indicates that the ANT produces reliable single subject estimates of alerting, orienting, and executive function, and further suggests that the efficiencies of these three networks are uncorrelated. There are, however, some interactions in which alerting and orienting can modulate the degree of interference from flankers. This procedure may prove to be convenient and useful in evaluating attentional abnormalities associated with cases of brain injury, stroke, schizophrenia, and attention-deficit disorder. The ANT may also serve as an activation task for neuroimaging studies and as a phenotype for the study of the influence of genes on attentional networks.
近年来,已从解剖学和功能角度定义了三种注意网络。这些功能包括警觉、定向和执行性注意。反应时测量可用于量化这三种网络中每一种的处理效率。注意网络测试(ANT)旨在在一个30分钟的测试环节内评估警觉、定向和执行性注意,儿童、患者和猴子都能轻松完成该测试。一项针对40名正常成年受试者的研究表明,ANT能对警觉、定向和执行功能产生可靠的单受试者估计值,并且进一步表明这三种网络的效率不相关。然而,在某些相互作用中,警觉和定向可以调节侧翼干扰的程度。该程序在评估与脑损伤、中风、精神分裂症和注意力缺陷障碍病例相关的注意异常方面可能被证明是方便且有用的。ANT还可作为神经影像学研究的激活任务以及用于研究基因对注意网络影响的一种表型。
