进化理论认为，适应行为取决于我们在生存所必需的时候优先关注情绪信息的能力，以及下调无关情绪影响的能力。然而，实证研究表明，情绪和注意力之间的相互作用是不同的，基于所讨论的注意力网络。本研究的目的是探讨刺激情绪性对注意的警觉、定向和执行功能的影响。在两项研究中，使用负面和中性线索的注意力网络测试的修改版本，人们发现，负面线索损害任务的表现，在没有执行冲突，但不是执行过程被激活。此外，它被发现，在一个给定的试验中，负性线索对任务绩效的影响减弱后，在以前的试验中执行过程的激活。这些结果表明，当需要执行资源时，抑制机制被招募来减少情绪刺激的破坏性影响。更重要的是，这些发现表明，情绪刺激对注意力的影响在认知冲突期间和冲突结束后都是下调的。
Evolution theory suggests that adaptive behavior depends on our ability to give preferential attention to emotional information when it is necessary for our survival, and to down-regulate irrelevant emotional influence. However, empirical work has shown that the interaction between emotion and attention varies, based on the attentional network in question. The aim of the current research was to examine the influence of stimulus emotionality on attention in three attentional networks: alerting, orienting, and executive functions. In two studies, using negative and neutral cues in a modified version of the Attention Network Test, it was found that negative cues impaired task performance in the absence of executive conflict, but not when executive processes were activated. Moreover, it was found that the influence of negative cues on task performance in a given trial was attenuated following activation of executive processes in the previous trial. These results suggest that when executive resources are required, inhibitory mechanisms are recruited to decrease the disruptive effect of emotional stimuli. More importantly, these findings indicate that the effect of emotional stimuli on attention is down-regulated both during cognitive conflict and after the conflict has already ended.
