青少年负性情绪面孔注意偏向眼动研究

The Eye-tracking Study of Attention Bias for Negative Emotional Faces of Teenagers

注意偏向与抑郁情绪的产生与维持存在紧密的联系.选取不同抑郁程度的40位在校初、高中学生完成情绪面孔的眼动追踪任务.结果显示,与低抑郁组相比,高抑郁组的青少年对悲伤表情在注意维持指标(首次注视时长和总注视时长)上表现出注意偏向.注意偏向值与抑郁程度呈显著正相关,此外,与低抑郁相比,高抑郁组关注高兴表情的时间略少,但在愤怒表情上,两组不存在差异.由此得出,抑郁个体的注意偏向仅与抑郁信息有关,且注意偏向主要发生在注意的后期.

Attention bias in depression plays a key role in the onset of depression.This study tracked 40 teenagers from junior and senior middle schoolswith depression of different levels for eye-tracking task.Compared to low depression group,high depression group showed a negative attention bias in maintenance indices(first fixation duration and total fixation time)for sad expression.The attention bias was positively associated with the severity of depressive symptoms.The high depression group spent less amount of time viewing happy expression compared with the low depression group.No differences were found between the groups with respect to angry expression.These results support the notion that attention bias in depression is specific to depression-related information,often occurs in later stages in deployment of attention.
