In the past decade, more and more research has been investigating oculomotor behavior in relation to attentional selection of emotional stimuli. Whereas previous research on covert emotional attention demonstrates contradictory results, research on overt attention clearly shows the influence of emotional stimuli on attentional selection. The current review highlights studies that have used eye-movement behavior as the primary outcome measure in healthy populations and focusses on the evidence that emotional stimuli-in particular, threatening stimuli-affect temporal and spatial dynamics of oculomotor programming. The most prominent results from these studies indicate that attentional selection of threatening stimuli is under bottom-up control. Moreover, threatening stimuli seem to have the greatest impact on oculomotor behavior through biased processing via the magnocellular pathway. This is consistent with an evolutionary account of threat processing, which claims a pivotal role for a subcortical network including pulvinar, superior colliculus, and amygdala. Additionally, I suggest a neurobiological model that considers possible mechanisms by which emotional stimuli could affect oculomotor behavior. The present review confirms the relevance of eye-movement measurements in relation to researching emotion in order to elucidate processes involved in emotional modulation of visual and attentional selection.
在过去十年中，越来越多的研究开始探讨与情绪刺激的注意力选择相关的眼动行为。以往关于隐蔽情绪注意力的研究结果相互矛盾，而关于公开注意力的研究则清楚地表明了情绪刺激对注意力选择的影响。本综述重点介绍了那些将眼动行为作为健康人群主要研究指标的研究，并聚焦于情绪刺激（尤其是威胁性刺激）影响眼动编程的时间和空间动态的证据。这些研究最突出的结果表明，对威胁性刺激的注意力选择受自下而上的控制。此外，威胁性刺激似乎通过大细胞通路的偏向性加工对眼动行为产生最大影响。这与威胁加工的进化理论相一致，该理论认为包括丘脑枕、上丘和杏仁核在内的皮层下网络起着关键作用。此外，我提出了一个神经生物学模型，该模型考虑了情绪刺激可能影响眼动行为的潜在机制。本综述证实了眼动测量在研究情绪方面的相关性，以便阐明视觉和注意力选择的情绪调节过程。
