In a set of three rapid serial visual presentation experiments, we investigated the effect of fearful and neutral face stimuli on the report of trailing scene targets. When the emotional expression of the face stimuli had to be indicated, fearful faces induced a stronger attentional blink (AB) than did neutral faces. However, with identical physical stimulation, the enhancement of the AB by fearful faces disappeared when participants had to judge the faces' gender. If faces did not have to be reported, no AB was observed. Thus, fearful faces exhibited an effect on the AB that crucially depended on the observer's attentional set. Hence, the AB can be influenced by an emotional T1 when T1 has to be reported, but this influence is modulated by task context. This result indicates a close connection between temporal attention and emotional processing that is modulated by task context.
在一组三个快速序列视觉呈现实验中，我们研究了恐惧和中性面部刺激对后续场景目标报告的影响。当必须指出面部刺激的情感表达时，恐惧面孔比中性面孔诱发更强的注意瞬脱（AB）。然而，在相同的物理刺激下，当参与者必须判断面孔的性别时，恐惧面孔对AB的增强作用消失了。如果不需要报告面孔，则未观察到AB。因此，恐惧面孔对AB的影响关键取决于观察者的注意定势。因此，当必须报告T1时，情感性T1会影响AB，但这种影响会受到任务背景的调节。这一结果表明，时间注意和情感加工之间存在紧密联系，且这种联系会受到任务背景的调节。
