背景资料。本研究考察了患有创伤后应激障碍(PTSD)的儿童和青少年和健康对照儿童和青少年对情绪材料的视觉注意偏差。受试者执行了一项注意部署任务，该任务使用探测检测潜伏期数据来确定威胁相关材料和抑郁相关材料的视觉注意分配。结果表明，与对照组相比，患有创伤后应激障碍的儿童和青少年有选择地将加工资源分配给社会威胁刺激，而不是与抑郁相关的刺激。创伤后应激障碍参与者对抑郁相关信息的注意回避随着年龄的增长而下降。这项研究的结果被解释为对先前关于年轻参与者的注意偏差和情绪障碍的研究的巩固和扩展。
Background. The present study examined biases in visual attention for emotional material in children and adolescents with post-traumatic stress disorder (PTSD) and healthy controls.Methods. The participants carried out an attentional deployment task in which probe detection latency data were used to determine the distribution of visual attention for threat-related and depression-related material.Results. The results showed that children and adolescents with PTSD, relative to controls, selectively allocated processing resources towards socially threatening stimuli and away from depression-related stimuli. This attentional avoidance of depression-related information in the PTSD participants declined with age.Conclusions. The results of the study an interpreted as a consolidation and extension of previous research on attentional bias and emotional disorder in younger participants.
