摘　　要：在早期注意分类理论研究的基础上,新近研究从注意的特定功能和解剖结构方面定义了三个分离的注意网络,分别为注意警觉,注意定向和执行控制。通过检验信号反应时任务中的靶子和线索效应,注意网络测试可有效探测注意系统中各网络的工作效率。大量神经成像研究结果发现注意网络在神经结构组织上的分离。然而,新近研究显示注意网络之间并非完全分离的关系。修订的注意网络测试对线索与目标间隔以及线索的有效性进行了调整,证实了注意网络功能整合的假设,注意网络中相关脑区间存在相互作用。本文对已有研究做了系统总结,并提出对未来研究的展望。Based on the early attentional classification theory, new studies define three terms about the at-tentional function from the anatomy and nerval function including alerting, orienting and execu-tive control. By examining the target and cue effects in the response time of the signal, it can be noted that the network testing can effectively detect the efficiency of each network in the system. Neuroimaging studies have confirmed that these networks have a certain degree of anatomical and functional independence. The attention network test (ANT) examines the effects of cues and targets within a single reaction time task to provide a means of exploring the efficiency of the alerting, orienting, and executive control networks involved in attention. However, some interactions in these three networks are proved. The revised attention network test (ANT-R) adjusts cue-target interval and cue validity. Related research results support the hypothesis of functional integration and interaction of these brain networks. In this paper, on the basis of existing research summary, the study proposed future prospects.
