创伤后应激障碍个体对威胁刺激的注意偏向：眼动研究的证据

对威胁刺激的注意偏向是创伤后应激障碍(PTSD)个体的一种表现。近年来, 研究者利用眼动技术探讨了注意偏向的加工特点及其内在机制。尽管针对是否存在注意定向加速、注意解除困难或注意回避的研究结果并不一致, 但都试图为验证如警戒-回避模型、注意保持模型等提供眼动证据。未来研究在记录PTSD个体注视模式时, 不仅需要从多个维度构建、整合PTSD个体的眼动模型, 也要结合多种技术从多模态角度共同考察PTSD个体的威胁信息注意偏向机制。

The attentional bias towards threat in posttraumatic stress disorder:Evidence from eye movement studies

Attentional bias towards threat is a common phenomenon in Posttraumatic Stress Disorder(PTSD)individuals.A number of studies have investigated the processing characteristics and internal mechanisms of attentional bias by using eye-movement technology.Results are inconsistent about components of attentional bias,but still provide evidences for different models,such as vigilance-avoidance model and attentional maintenance model.Based on eye-movement patterns from different dimensions,the future studies should pay attention to the model building and integration while recording the eye movements of PTSD individuals.Furthermore,researchers could combine multiple technologies to investigate the threat attention bias mechanism of PTSD individuals from a multimodal perspective.
