摘要
注意偏向是指在相对于中性刺激的条件下,个体对威胁性、特定事件相关的刺激或感觉输入表现出优先性的注意分配现象。通常情况下,注意偏向会导致个体对外界信息获取不完整,从而出现信息记忆不完全,容易出现错误的判断。虽然一些研究已经表明创伤后应激障碍患者表现出明显的注意偏向,但是对于PTSD患者注意偏向的本质还不清楚。本研究采用点探测范式,利用眼动追踪技术,探讨了震后PTSD青少年对情绪图片注意偏向的时间进程。研究被试分为三组,一组为地震创伤暴露PTSD青少年(n=21),一组为地震创伤暴露非PTSD青少年(n=20),另一组为非创伤暴露控制组青少年(n=21)。情绪图片选自国际情绪图片库,经过了效价和唤醒度的评定,分为正性、负性和中性。采用SMI RED250型眼动仪记录被试的眼动轨迹。结果发现,与地震创伤暴露非PTSD青少年和控制组相比,创伤暴露PTSD青少年对情绪图片表现出显著的注意偏向,具体表现在加工时间和眼跳概率等指标上,表明PTSD青少可能存在一定的注意加工缺陷。整个研究表明,对情绪图片的注意偏向可以作为区分PTSD和非PTSD的认知指标之一。
Attentional bias is an occurrence wherein a person focuses more of his attention toward a specific stimulus or a sensory cue. Often, this leads to a poor sense of judgment or an incomplete recollection of a certain event or memory. Although several studies have documented an attentional bias toward threat in posttraumatic stress disorder(PTSD), the nature of attentional bias has not been clearly delineated. The present study utilized eye tracking technology to delineate the time course and components of attentional bias for emotion pictures in earthquake related PTSD. Earthquake survivor teenagers with PTSD symptoms(n = 21), earthquake survivor teenagers without PTSD(n = 20), and non-trauma teenagers control group(n = 20) viewed trauma related pictures paired with neutral pictures for 3s presentations. Eye movements were record with SMI RED500 eye tracker. The results showed that teenagers with PTSD maintained attention longer on the emotion pictures. This attentional bias was robustly distinguished teenagers with PTSD from both teenagers without PTSD and non-trauma teenagers controls. Its indicated that dwelling on threat cues may reflect current PTSD symptoms, and it could reflect a cognitive vulnerability factor for PTSD.
