ABSTRACT

In spatial cueing paradigms, emotional stimuli generally orient attention more efficiently, leading to modulations of behavioural and neuronal responses according to stimulus valence. In a previous study, we showed that when emotional stimuli are not consciously perceived, they cannot orient attention and that emotion is not processed when attentional load is high. In the present studies, we were able to confirm these behavioural findings, even when stimulus duration is randomized, which was not the case in the original study. These results confirm the original findings and show that even in a randomized sequence, irrelevant emotional expressions displayed under the threshold of awareness do not capture attention when the task involves high attentional load.

摘要

在空间提示范式中，情绪刺激通常更有效地引导注意力，从而根据刺激效价调节行为和神经元反应。在之前的一项研究中，我们表明，当没有有意识地感知情绪刺激时，它们无法引导注意力，并且当注意力负荷高时，情绪不会得到处理。在目前的研究中，我们能够证实这些行为发现，即使刺激持续时间是随机的，而原始研究中并非如此。这些结果证实了最初的发现，并表明即使在随机序列中，当任务涉及高注意力负荷时，在意识阈值下显示的不相关情绪表达也不会引起注意。
