While wearing an EEG cap, participants were asked to push a button with their right index finger for real items and another button with their right middle finger for nonreal/scrambled items. Shorter response times were recorded for scrambled images than the real images. There was no difference in reaction time for threatening versus non-threatening images.

在戴着脑电图帽的同时，参与者被要求用右手食指按下按钮以看到真实图片，另用右手中指按另一个按钮以看到不真实的图片或乱码。乱码图像比真正的图像记录的响应时间更短。威胁性图片和不具威胁性的图片在反应时间上没有差别。

EEG results revealed that threatening images evoked an early increase in theta activity in the occipital lobe (the area in the brain where visual information is processed), followed by a later increase in theta power in the frontal lobe (where higher mental functions such as thinking, decision-making, and planning occur). A left lateralized desynchronization of the beta band, the wave pattern associated with motor behavior (like the impulse to run), also consistently appeared in the threatening condition.

脑电图结果表明威胁图片诱发枕叶（大脑中处理视觉信息的区域）中的θ波活动早期增加，紧随其后的是枕叶区域（更高级的心理机能，如思考、决策和计划，在这里发生）θ波的增加。β波左单侧性的去同步化，与运动行为(如脉冲运行)相关的波动行为，也一再出现在威胁情况下。
