Previous research has revealed the influence of reward associations on attentional selection and control. The attentional network can be divided into three components according to its function: Alerting, orienting, and executive control. In the current research, we used training-test procedure and attention network test variant to investigate the effects of color-based reward associations on alerting (Experiment 1), orienting (Experiment 2), executive control (Experiment 3), as well as the interactions among these three networks (Experiment 4). The findings were as follows: Compared with colors previously associated with low reward, colors previously associated with high reward trigger stronger alerting and orienting effects (Experiments 1 and 2), and they had stronger interference effects when functioning as features of flanker distractor (Experiment 3). More importantly, reward associations had only a positive impact on the interaction of orienting by executive control but not on the interaction of alerting by executive control (Experiment 4). In summary, reward associations have different effects on the three attentional networks and can enhance the interaction of orienting by executive control.
先前的研究揭示了奖励关联对注意力选择和控制的影响。根据其功能，注意力网络可分为三个组成部分：警戒、定向和执行控制。在当前的研究中，我们使用训练-测试程序和注意网络测试变体来研究基于颜色的奖励关联对警戒（实验 1）、定向（实验 2）、执行控制（实验 3）以及这三个网络之间相互作用（实验 4）的影响。研究结果如下：与先前与低奖励相关联的颜色相比，先前与高奖励相关联的颜色会引发更强的警戒和定向效应（实验 1 和实验 2），并且当它们作为侧翼干扰特征时会产生更强的干扰效应（实验 3）。更重要的是，奖励关联仅对执行控制的定向相互作用产生积极影响，而对执行控制的警戒相互作用没有影响（实验 4）。总之，奖励关联对三个注意力网络有不同的影响，并可以增强执行控制的定向相互作用。
