Across three experiments, we examined the efficacy of three cues from the human body-body orientation, head turning, and eye-gaze direction-to shift an observer's attention in space. Using a modified Posner cueing paradigm, we replicate the previous findings of gender differences in the gaze-cueing effect whereby female but not male participants responded significantly faster to validly cued than to invalidly cued targets. In contrast to the previous studies, we report a robust cueing effect for both male and female participants when head turning direction was used as the central cue, whereas oriented bodies proved ineffectual as cues to attention for both males and females. These results are discussed with reference to the time course of central cueing effects, gender differences in spatial attention, and current models of how cues from the human body are combined to judge another person's direction of attention.
在三项实验中，我们研究了来自人体的三种线索——身体朝向、转头和目光注视方向——在空间中转移观察者注意力的效果。使用改良的波斯纳线索范式，我们重复了之前关于注视线索效应中性别差异的研究结果，即女性参与者对有效线索提示的目标反应明显快于对无效线索提示的目标，而男性参与者则不然。与之前的研究不同，我们发现当以转头方向作为主要线索时，男性和女性参与者都有显著的线索效应，而身体朝向对男性和女性作为注意力线索都无效。我们结合中央线索效应的时间进程、空间注意力的性别差异以及当前关于如何整合来自人体的线索以判断他人注意力方向的模型来讨论这些结果。
