人类会注意脸部。这项研究考察了对面孔的注意力偏向在多大程度上受到自上而下的控制。在视觉线索范式中，观察者对出现在面孔线索位置的目标探测器的反应比出现在竞争物体线索位置的目标探测器更快(实验1a和2a)。当面孔对可能的目标位置有负面预测时，这种效应可能会被逆转，从而有利于注意物体线索(实验1b和2b)。更容易的是策略性地将注意力转移到预测性面孔线索(实验2c)，这表明内源性注意力分配在这里通过额外的效应得到了增强。然而，面孔只是推迟了对物体线索的自愿注意力分配，但它们不能阻止它，即使是在很短的线索-目标间隔。这一发现表明，观察者的内源性控制可以迅速抵消对面孔的注意偏差。
Humans attend to faces. This study examines the extent to which attention biases to faces are under top-down control. In a visual cueing paradigm, observers responded faster to a target probe appearing in the location of a face cue than of a competing object cue (Experiments 1a and 2a). This effect could be reversed when faces were negatively predictive of the likely target location, making it beneficial to attend to the object cues (Experiments 1b and 2b). It was easier still to strategically shift attention to predictive face cues (Experiment 2c), indicating that the endogenous allocation of attention was augmented here by an additional effect. However, faces merely delayed the voluntary deployment of attention to object cues, but they could not prevent it, even at short cue-target intervals. This finding suggests that attention biases for faces can be rapidly countered by an observer's endogenous control.
