在对环境变化作出反应的同时，抵抗分心和专注于与任务相关的信息的能力是目标导向行为的基础。这种注意控制能力是由先前描述的自下而上和自上而下的注意网络之间的持续相互作用调节的。在这里，我们询问这两个注意网络中可能调节增强注意控制的神经变化。为了解决这个问题，我们在Posner线索范式中对比了动作视频游戏玩家(AVGP)和非视频游戏玩家(NVGP)，建立在记录AVGP增强注意力控制的研究基础上。行为结果表明，在AVGP中有更有效的目标处理的趋势，在罕见的捕获试验中有更好的抑制，对这些试验的反应必须被扣留。在提示期间，AVGP招募自上而下的网络比NVGP少，尽管显示出类似的效度效果，这与AVGP中该网络的更高效率一致。如前所述，在目标处理期间，自上而下区域的招募与更大的处理困难相关，但仅在非VGP中。AVGP没有这种影响，但在这两个网络中表现出更大的激活。特别是，右侧顶叶交界处、额中回和顶上皮质在CATCH试验中预示着更好的任务表现。功能连接性分析显示，与NVGP相比，AVGP在顶区和视区之间的相关活动增强。这些结果表明，随着注意需求的不同，AVGP中自上而下和自下而上的注意网络的动态功能重构。讨论了可作为高注意控制的关键特征的这种功能重新配置的各个方面。
The ability to resist distraction and focus on‐task‐relevant information while being responsive to changes in the environment is fundamental to goal‐directed behavior. Such attentional control abilities are regulated by a constant interplay between previously characterized bottom‐up and top‐down attentional networks. Here we ask about the neural changes within these two attentional networks that may mediate enhanced attentional control. To address this question, we contrasted action video game players (AVGPs) and nonvideo game players (NVGPs) in a Posner‐cueing paradigm, building on studies documenting enhanced attentional control in AVGPs. Behavioral results indicated a trend for more efficient target processing in AVGPs, and better suppression in rare catch trials for which responses had to be withheld. During the cue period, AVGPs recruited the top‐down network less than NVGPs, despite showing comparable validity effects, in line with a greater efficiency of that network in AVGPs. During target processing, as previously shown, recruitment of top‐down areas correlated with greater processing difficulties, but only in NVGPs. AVGPs showed no such effect, but rather greater activation across the two networks. In particular, the right temporoparietal junction, middle frontal gyrus, and superior parietal cortex predicted better task performance in catch trials. A functional connectivity analysis revealed enhanced correlated activity in AVGPs compared to NVGPs between parietal and visual areas. These results point to dynamic functional reconfigurations of top‐down and bottom‐up attentional networks in AVGPs as attentional demands vary. Aspects of this functional reconfiguration that may act as key signatures of high attentional control are discussed.
