Auditory probe evoked potential attenuation was measured as an index of hemispheric activity in 10 subjects with a history of childhood trauma and 10 matched subjects without such history while they recalled a neutral memory and then a traumatic memory. There were prominent group differences in degree of cerebral laterality between memory tasks (P = 0.02). The trauma group had a significant left dominant asymmetry during the neutral memory (P = 0.02), which markedly shifted to the right during the unpleasant memory (P = 0.007 for degree of shift). Normal control subjects did not display a significant asymmetry during either task, nor did they show a significant shift between tasks.
在10名有童年创伤史的受试者和10名无此类病史的匹配受试者回忆中性记忆然后是创伤性记忆时，测量听觉诱发电位衰减作为半球活动的指标。在记忆任务之间，大脑半球偏侧化程度存在显著的组间差异（P = 0.02）。创伤组在中性记忆期间存在显著的左优势不对称（P = 0.02），在不愉快记忆期间明显转向右侧（偏移程度P = 0.007）。正常对照受试者在任何一项任务中均未表现出显著的不对称，也未在任务之间表现出显著的偏移。
