快速发现与进化相关的威胁（例如，可怕的面孔）对人类的生存很重要。快速识别恐惧面孔的能力在个体之间表现出很大的差异。本研究采用事件相关电位（ERP）和事件相关振荡（ERO）两种测量方法，探讨行为检测能力与脑活动之间的关系。在后向掩蔽范式中，恐惧面部表情和中性面部表情分别被呈现17 ms和200 ms。42名参与者被要求辨别蒙面者的面部表情。行为敏感性指数d'表明，不同参与者对快速呈现和掩盖恐惧面孔的检测能力有所不同。方差分析显示，面部表情、脑半球和呈现时间影响刺激后大平均ERP （N1、P1和N170）和ERO（低于20 Hz，持续时间为100 ms至250 ms，主要在θ波段）脑活动。更重要的是，42名被试的整体检测能力与ERP （r = 0.403）和ERO （r = 0.552）测量的情绪效应（即恐惧与中性）显著相关。d′值越高，对应的N170振幅的情绪效应（即恐惧-中性）越大，对应的右半球特定ERO谱功率的情绪效应越大。结果表明，个体的行为检测能力与N170振幅和低于20 Hz的ERO频谱功率密切相关。恐惧面孔和中性面孔在大脑活动中的情绪效应大小可能反映了恐惧面孔的意识意识水平。
Rapid detection of evolutionarily relevant threats (e.g., fearful faces) is important for human survival. The ability to rapidly detect fearful faces exhibits high variability across individuals. The present study aimed to investigate the relationship between behavioral detection ability and brain activity, using both event-related potential (ERP) and event-related oscillation (ERO) measurements. Faces with fearful or neutral facial expressions were presented for 17 ms or 200 ms in a backward masking paradigm. Forty-two participants were required to discriminate facial expressions of the masked faces. The behavioral sensitivity index d' showed that the detection ability to rapidly presented and masked fearful faces varied across participants. The ANOVA analyses showed that the facial expression, hemisphere, and presentation duration affected the grand-mean ERP (N1, P1, and N170) and ERO (below 20 Hz and lasted from 100 ms to 250 ms post-stimulus, mainly in theta band) brain activity. More importantly, the overall detection ability of 42 subjects was significantly correlated with the emotion effect (i.e., fearful vs. neutral) on ERP (r = 0.403) and ERO (r = 0.552) measurements. A higher d' value was corresponding to a larger size of the emotional effect (i.e., fearful – neutral) of N170 amplitude and a larger size of the emotional effect of the specific ERO spectral power at the right hemisphere. The present results suggested a close link between behavioral detection ability and the N170 amplitude as well as the ERO spectral power below 20 Hz in individuals. The emotional effect size between fearful and neutral faces in brain activity may reflect the level of conscious awareness of fearful faces.
