摘要
Posner和Petersen把注意系统分为警觉、定向和执行控制三个网络。注意网络测验及其变式是研究注意网络间关系的主要工具。生物化学、神经影像和行为研究从神经递质广泛调节、脑功能区共享、注意资源竞争和认知策略调节的角度证明了三个注意网络之间既相互独立又有机统一的关系。测量信度低、定义模糊成为注意网络及其关系的研究中亟待解决的问题。将来的研究需要改进测量工具,并考虑注意网络的子成分对网络间关系的影响。
According to Posner and Petersen （1990）, the attention system is divided into alerting, orienting, and executive control networks. The relationships among attention networks have been tested with attention network test （ANT） and its revised versions. Biochemical, neuroimaging, and behavioral studies have demonstrated the differentiated but integrated relation of attention networks. Specifically, the interaction between attention networks is supported by the evidence that different attention networks share functional brain regions and neurotransmitters, compete for attention resources, and are modulated by cognitive strategies. Urgent issues exist in measuring of attention networks and their relationships, such as the low reliability of the ANT and ambiguous definitions of attention networks. Future studies should focus on improving the ANT and take into account the influence of subcomponents of attention networks on inter-network relationships.
