众所周知,情绪可以调节注意过程。先前的研究表明,即使在有限的意识下,情绪化的面部表情(特别是与威胁有关的)也可以引导空间注意力的方向。然而,目前还不清楚是否情绪面部表情限制意识会影响时间注意。为了解决这个问题,我们使用了一个修改的注意瞬脱(AB)的范式,其中掩蔽(实验1)或未掩蔽(实验2)的情绪面孔(恐惧或中性)之前的AB序列。我们发现,与中性面孔相比,蒙面恐惧面孔显着降低AB幅度(实验1),而未蒙面的恐惧面孔显着增加AB幅度(实验2)。这些结果表明,情绪表达对AB的影响是由意识水平调制的。
It is well known that emotion can modulate attentional processes. Previous studies have shown that even under restricted awareness, emotional facial expressions (especially threat-related) can guide the direction of spatial attention. However, it remains unclear whether emotional facial expressions under restricted awareness can affect temporal attention. To address this issue, we used a modified attentional blink (AB) paradigm in which masked (Experiment 1) or unmasked (Experiment 2) emotional faces (fearful or neutral) were presented before the AB sequence. We found that, in comparison with neutral faces, masked fearful faces significantly decreased the AB magnitude (Experiment 1), whereas unmasked fearful faces significantly increased the AB magnitude (Experiment 2). These results indicate that effects of emotional expression on the AB are modulated by the level of awareness.
