本研究以眼动作为选择性注意的指标，考察了7-17岁焦虑和非焦虑儿童和青少年注意偏向的时间进程。参与者完成了两项眼动追踪任务，分别观察了3000 ms和500 ms的快乐中性和消极中性面孔对。当面孔对呈现3000毫秒时，眼动数据显示在注意处理的任何阶段都没有注意偏向的证据。当面对对500毫秒的偏见在初始定向发生，焦虑的青少年指导他们的第一个固定远离消极的面孔和焦虑的儿童指导他们的第一个固定远离快乐的面孔。结果表明，儿童期焦虑的特点是在初始定向的偏见，没有偏见的持续关注，虽然只有简短介绍的面孔。皇冠版权所有（C）2009由爱思唯尔有限公司出版。保留所有权利。
This study examined the time-course of attentional bias in anxious and non-anxious children and adolescents aged 7-17 years using eye movement as an index of selective attention. Participants completed two eye-tracking tasks in which they viewed happy-neutral and negative-neutral face pairs for 3000 and 500 ms, respectively. When face pairs were presented for 3000 ms eye movement data showed no evidence of an attentional bias at any stage of attentional processing. When face pairs were presented for 500 ms a bias in initial orienting occurred; anxious adolescents directed their first fixation away from negative faces and anxious children directed their first fixation away from happy faces. Results suggest that childhood anxiety is characterized by a bias in initial orienting, with no bias in sustained attention, although only for briefly presented faces.
