点探针研究表明，被掩盖的恐惧面孔调节空间注意。然而，由于没有一个基线来比较一致和不一致的反应时间，目前还不清楚注意力的哪个方面（定向或脱离）受到影响。此外，向后掩蔽研究通常使用中性面孔作为掩蔽刺激。这种方法会导致对恐惧面孔的知觉不一致性比对中性面孔的知觉不一致性更大。因此，目前尚不清楚向后掩蔽恐惧面孔的影响是由于面孔的恐惧性质还是感知不一致。同样不清楚的是，这种空间注意力效应是由于定向还是脱离。两个改进的点探针实验中性（实验1中的嘴关闭）和微笑（实验2中的嘴打开）面具被用来确定的作用，知觉不一致的介导的空间注意效应引起的蒙面恐惧的面孔。结果表明，蒙面恐惧的面孔调节空间注意的定向，它似乎是由于脸的恐惧性质，而不是最初的面孔和面具之间的知觉不一致。
Dot probe studies indicate that masked fearful faces modulate spatial attention. However, without a baseline to compare congruent and incongruent reaction times, it is unclear which aspect(s) of attention (orienting or disengagement) is affected. Additionally, backward masking studies commonly use a neutral face as the mask stimulus. This method results in greater perceptual inconsistencies for fearful as opposed to neutral faces. Therefore, it is currently unclear whether the effects of backward masked fearful faces are due to the fearful nature of the face or perceptual inconsistencies. Equally unclear, is whether this spatial attention effect is due to orienting or disengagement. Two modified dot probe experiments with neutral (closed mouth in Experiment 1) and smiling (open mouth in Experiment 2) masks were used to determine the role of perceptual inconsistencies in mediating the spatial attention effects elicited by masked fearful faces. The results indicate that masked fearful faces modulate the orienting of spatial attention, and it appears that this effect is due to the fearful nature of the face rather than perceptual inconsistencies between the initial faces and masks.
