摘要: Objective and Methods: To investigate the neural correlates of earthquake-related stimuli among earthquake-exposed survivors, 13 undergraduates without posttraumatic stress disorder (PTSD) matched controls completed a study-test task during which event-related potentials were recorded synchronously. Results: The group exhibited stronger P2, P300 late positive component amplitudes to compared with control on anterior scalp recognition memory processing. In addition, elicited enhanced positivity neutral in group. Conclusion: results indicate that subjects demonstrate bias toward threatening stimuli. Even though both groups showed no PTSD symptoms, potential threat cues or associated traumatic event may trigger memories this
