The aim of this study was to investigate whether emotion-attention interaction depends on attentional engagement. To investigate emotional modulation of attention network activation, we used a functional MRI paradigm consisting of a visuospatial attention task with either frequent (high-engagement) or infrequent (low-engagement) targets and intermittent emotional or neutral distractors. The attention task recruited a bilateral frontoparietal network with no emotional interference on network activation when the attentional engagement was high. In contrast, when the attentional engagement was low, the unpleasant stimuli interfered with the activation of the frontoparietal attention network, especially in the right hemisphere. This study provides novel evidence for low attentional engagement making attention control network activation susceptible to emotional interference.
本研究的目的是调查情绪-注意力交互作用是否依赖于注意力投入。为了研究注意力网络激活的情绪调节，我们采用了一种功能磁共振成像范式，该范式包括一个视觉空间注意力任务，其中有频繁（高投入）或不频繁（低投入）的目标以及间歇性的情绪性或中性干扰物。当注意力投入较高时，注意力任务募集了一个双侧额顶叶网络，且网络激活没有受到情绪干扰。相比之下，当注意力投入较低时，不愉快刺激会干扰额顶叶注意力网络的激活，尤其是在右半球。本研究为低注意力投入使注意力控制网络激活易受情绪干扰提供了新证据。
