背景：本研究调查了处理情绪显着信息（例如情绪面部表情）是否会影响儿童焦虑和抑郁的认知控制任务的表现。方法：样本包括 68 名 8 至 16 岁的参与者，分为三个诊断组：焦虑症 (ANX，n = 23)、重度抑郁症 (MDD，n = 19) 和低风险正常对照 (LRNC，n = 26)。参与者完成了情感 Go/NoGo 任务，其中参与者必须对特定的面部表情（愤怒、恐惧、悲伤、快乐、中立）做出反应（Go 试验）或不反应（NoGo 试验）。为了操纵执行任务所需的认知控制水平，围棋试验的发生概率在 3 个概率条件（低、中、高）中变化。结果：分析表明，在中等概率条件下，MDD 组对嵌入中性脸 NoGo 试验的悲伤脸 Go 试验的反应时间明显更快，而 ANX 组在低概率条件下对嵌入愤怒脸 NoGo 试验的中性脸 Go 试验的反应时间明显较慢。结论：这些数据表明，处理情绪面部表情会影响被诊断患有焦虑症和重度抑郁症的儿童和青少年的认知控制任务表现。
Background: This study investigated whether processing emotionally salient information such as emotional facial expressions influences the performance on a cognitive control task in pediatric anxiety and depression. Methods: The sample included 68 participants between 8 and 16 years of age selected into three diagnostic groups: Anxiety Disorder (ANX, n = 23), Major Depressive Disorder (MDD, n = 19), and Low-Risk Normal Control (LRNC, n = 26). Participants completed an Emotional Go/NoGo task in which participants must either respond to (Go trials) or not respond to (NoGo trials) specific facial expressions (angry, fearful, sad, happy, neutral). In order to manipulate the level of cognitive control needed to perform the task, the probability of occurrence of the Go trials was varied across 3 probability conditions (low, moderate, high). Results: Analyses showed that the MDD group had significantly faster reaction times to sad face Go trials embedded in neutral face NoGo trials in the moderate probability condition and that the ANX group had significantly slower reaction times to neutral face Go trials embedded in angry face NoGo trials in the low probability condition. Conclusions: These data demonstrate that processing emotional facial expressions influences the performance on a cognitive control task in children and adolescents diagnosed with an anxiety disorder and major depression.
