We investigated the effects of facial expression on shared attention mechanisms. A female or male facial stimulus with one of 3 facial expressions (happiness, neutral, or anger) was presented at the center of a display. This facial stimulus gazed toward a subject, or toward the left or right side of the display. After the facial stimulus was offset, a target appeared on the left or right side of the display and the reaction time to the target was measured. In the statistical analysis by ANOVA, there was a significant main effect of congruity between the target position and the gaze direction in both the female and male facial cues, indicating that gaze direction significantly affected reaction time. When the female facial cues were presented, the reaction times for the congruent target position to the gaze direction were significantly shorter in the happy than other facial expressions. However, there were no significant differences in reaction time when the facial stimuli were presented in an inverted orientation. The results demonstrated that facial expression significantly affected shared attention mechanisms.
我们研究了面部表情对共同注意机制的影响。在显示屏中央呈现带有三种面部表情（快乐、中性或愤怒）之一的女性或男性面部刺激。该面部刺激看向一名受试者，或看向显示屏的左侧或右侧。面部刺激消失后，一个目标出现在显示屏的左侧或右侧，并测量对该目标的反应时间。在通过方差分析进行的统计分析中，在女性和男性面部线索中，目标位置与注视方向之间的一致性存在显著的主效应，表明注视方向显著影响反应时间。当呈现女性面部线索时，与注视方向一致的目标位置的反应时间在快乐表情时比其他面部表情显著更短。然而，当面部刺激以倒置方向呈现时，反应时间没有显著差异。结果表明，面部表情显著影响共同注意机制。
