采用点探测研究范式,对高分离个体和低分离个体在两种呈现时间500ms和1500ms条件下,随机呈现创伤性图片和中性图片,进行点探测反应,考察创伤性分离个体的注意加工特点。结果表明,高分离个体在500ms呈现时间条件下对创伤性图片的反应时间显著快于低分离个体对创伤图片刺激的反应时间,而在1500ms呈现时间条件下则显著慢于低分离个体。表明创伤性高分离个体的注意加工符合警戒-回避的时程性模式:开始时对创伤性刺激是一种保护性的警戒反应;在随后刺激的呈现时间增加时,回避对创伤相关信息的进一步编码和精细加工,出现有意遗忘,体现在提取和回忆上的减弱,我们称之为回避加工。
Using point detection research paradigm, traumatic pictures and neutral pictures were randomly presented in both high-resolution and low-resolution individuals at 500 ms and 1500 ms for two presentation times, and point detection reaction was conducted to investigate the attention processing characteristics of traumatic individuals. The results showed that the response time of highly isolated individuals to traumatic pictures at 500ms presentation time was significantly faster than that of low-resolution individuals on stimulation of trauma pictures, but was significantly slower than that of low-resolution individuals at 1500ms presentation time. Suggests that traumatic, highly-discrete individuals are vigilant-evasive temporal patterns: a protective cautionary response to traumatic stimuli at the outset; evasive traumatic-related messages as presentation times of subsequent stimuli increase Coding and finishing, there is deliberately forgotten, reflected in the abstraction and recall on the weakened, we call it to avoid processing.
