The purpose of the present study was to investigate the effects of posttraumatic stress disorder (PTSD) associated with the effects of emotional valence on recall processes in recognition memory. Patients suffering from PTSD (n = 15) were compared with 15 nontraumatized patients with anxious and depressive symptoms and with 15 nontraumatized controls on the remember/know paradigm using negative, positive, and neutral words. The PTSD group remembered more negative words than the nontraumatized controls, F(1, 42) = 7.20, p = .01, but there was no difference between those with PTSD and those with anxiety or depression, F(1, 42) = 2.93, p = .09, or between the latter and controls, F(1, 42) < 1. This study did not allow us to determine whether this recollection bias for negative information was specific to the PTSD status or was triggered by the greater level of anxiety displayed in this group.
本研究旨在探讨创伤后应激障碍（PTSD）对情绪效价对再认记忆中回忆过程的影响。使用负性、正性和中性词汇，将 PTSD 患者（n = 15）与有焦虑和抑郁症状的未受创伤患者（n = 15）和未受创伤对照者（n = 15）进行比较，采用“记得/知道”范式。PTSD 组比未受创伤对照组更能记住负性词汇，F（1，42）= 7.20，p =.01，但 PTSD 组与焦虑或抑郁组之间没有差异，F（1，42）= 2.93，p =.09，或与对照组之间没有差异，F（1，42）<1。本研究尚不能确定这种对负性信息的回忆偏差是特定于 PTSD 状态还是由该组表现出的更高水平的焦虑所触发。
