Adult work shows differences in emotional processing influenced by sexes of both the viewer and expresser of facial expressions. We investigated this in 120 healthy youths (57 boys; 10-17 years old) randomly assigned to fear conditioning and extinction tasks using either neutral male or female faces as the conditioned threat and safety cues, and a fearful face paired with a shrieking scream as the unconditioned stimulus. Fear ratings and skin conductance responses (SCRs) were assessed. Male faces triggered increased fear ratings in all participants during conditioning and extinction. Greater differential SCRs were observed in boys viewing male faces and in girls viewing female faces during conditioning. During extinction, differential SCR findings remained significant in boys viewing male faces. Our findings demonstrate how sex of participant and sex of target interact to shape fear responses in youths, and how the type of measure may lead to distinct profiles of fear responses.
成人研究表明，面部表情观察者和表达者的性别会影响情绪处理过程中的差异。我们对120名健康青少年（57名男孩，年龄在10至17岁之间）进行了调查，他们被随机分配到恐惧条件反射和消退任务中，使用中性男性或女性面孔作为条件性威胁和安全线索，并将一张恐惧面孔与一声尖叫作为无条件刺激。我们评估了恐惧评分和皮肤电传导反应（SCR）。在条件反射和消退过程中，男性面孔在所有参与者中都引发了更高的恐惧评分。在条件反射过程中，男孩观看男性面孔和女孩观看女性面孔时观察到更大的差异SCR。在消退过程中，男孩观看男性面孔时差异SCR结果仍然显著。我们的研究结果表明参与者的性别和目标的性别如何相互作用以塑造青少年的恐惧反应，以及测量类型如何导致不同的恐惧反应特征。
