之前的功能磁共振成像和事件相关脑电位研究表明，执行认知任务可能会抑制情绪刺激的优先处理。然而，这些研究使用的是简单和人为的任务(即字母、形状或方向辨别任务)，参与者不熟悉。目前的事件相关电位研究在一个相对自然的场景分类任务的背景下考察了情绪-注意的交互作用。对于参与者来说，判断一个自然场景是否包含动物是一项熟悉而有意义的任务，而且被认为需要很少的注意力资源。任务图像集中呈现，并叠加在情绪性或中性背景图片上。因此，内隐情绪和外显语义分类可能会竞争物体识别所涉及的神经区的加工资源。此外，参与者被动地观看相同的刺激材料，而不需要对任务图像进行分类。任务条件与情绪图画效价在枕叶负向和晚期正向电位上存在显著交互作用。在被动观看条件下，情绪背景图像引起枕叶负性增加，随后是晚期正性电位增加。而在动物/非动物归类任务中，情绪调节效应被较强的目标归类效应所取代。这些结果表明，当两个加工都在争夺共享资源时，外显语义分类干扰了内隐情绪加工。
Previous functional magnetic resonance imaging and event-related brain potential studies revealed that performing a cognitive task may suppress the preferential processing of emotional stimuli. However, these studies utilized simple and artificial tasks (i.e. letter, shape or orientation discrimination tasks), unfamiliar to the participants. The present event-related potential study examined the emotion–attention interaction in the context of a comparably more natural scene categorization task. Deciding whether a natural scene contains an animal or not is a familiar and meaningful task to the participants and presumed to require little attentional resources. The task images were presented centrally and were overlaid upon emotional or neutral background pictures. Thus, implicit emotion and explicit semantic categorization may compete for processing resources in neural regions implicated in object recognition. Additionally, participants passively viewed the same stimulus materials without the demand to categorize task images. Significant interactions between task condition and emotional picture valence were observed for the occipital negativity and late positive potential. In the passive viewing condition, emotional background images elicited an increased occipital negativity followed by an increased late positive potential. In contrast, during the animal-/non-animal-categorization task, emotional modulation effects were replaced by strong target categorization effects. These results suggest that explicit semantic categorization interferes with implicit emotion processing when both processes compete for shared resources.
