本研究的目的是测试是否儿童和青少年焦虑症表现出选择性处理的威胁性面部表情的图片版本的情绪Stroop范式。参与者命名过滤器的颜色，覆盖成人和儿童的图像，显示中性的面部表情或显示愤怒，厌恶或快乐的情绪。在说出滤光片颜色时的延迟意味着注意力被面部表情捕获。焦虑的参与者，相对于控制参与者，表现出较慢的颜色命名整体，这意味着更大的倾向于分心的社会线索。与青少年相比，儿童表现出更长的颜色命名延迟，这可能是因为幼儿抑制注意力分散刺激的能力有限。成人的脸与缓慢的颜色命名比儿童的脸，无论在这两个群体的面部表情，可能是因为成人提供特别突出的线索，儿童和青少年。与预测不一致的是，患有焦虑症的参与者在命名覆盖威胁性表情的过滤器的颜色时并不比健康对照慢（即，愤怒和厌恶）相对于覆盖描绘快乐或中性表情的面部的过滤器。
The purpose of this study was to test whether children and adolescents with anxiety disorders exhibit selective processing of threatening facial expressions in a pictorial version of the emotional Stroop paradigm. Participants named the colours of filters covering images of adults and children displaying either a neutral facial expression or one displaying the emotions of anger, disgust, or happiness. A delay in naming the colour of a filter implies attentional capture by the facial expression. Anxious participants, relative to control participants, exhibited slower colour naming overall, implying greater proneness to distraction by social cues. Children exhibited longer colour-naming latencies as compared to adolescents, perhaps because young children have a limited ability to inhibit attention to distracting stimuli. Adult faces were associated with slower colour naming than were child faces, irrespective of facial expressions in both groups, possibly because adults provide especially salient cues for children and adolescents. Inconsistent with prediction, participants with anxiety disorders were not slower than healthy controls at naming the colours of filters covering threatening expressions (i.e., anger and disgust) relative to filters covering faces depicting happy or neutral expressions.
