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.

青少年恐惧的调节和消失：性与它有什么关系？

成人作品显示出受观看者和面部表情表达者性别影响的情绪处理差异。我们在 120 名健康青年（57 名男孩；10-17 岁）中对此进行了调查，他们使用中性的男性或女性面孔作为条件威胁和安全提示，将恐惧的面孔与尖叫声配对作为恐惧条件反射和灭绝任务。无条件刺激。评估了恐惧等级和皮肤电导反应 (SCR)。在调节和灭绝过程中，男性面孔引发了所有参与者的恐惧评级增加。在调节期间观察男性面部的男孩和观察女性面部的女孩观察到更大的差异 SCR。在灭绝过程中，男孩观察男性面孔时，不同的 SCR 发现仍然显着。
