| Abstract: | ObjectiveWe investigated gender differences in event-related potential (ERP) responses to subliminally presented threat-related stimuli.MethodsTwenty-four participants were presented with threat-related and neutral pictures for a very brief period of time (17 ms). To explore gender differences in ERP responses to subliminally presented stimuli, we examined six ERP components P1, N170, N250, P300, Early Posterior Negativity (EPN) and Late Positive Potential (LPP)].ResultsThe result revealed that only female participants showed significant increases in the N170 and the EPN in response to subliminally presented threat-related stimuli compared to neutral stimuli.ConclusionOur results suggest that female participants exhibit greater cortical processing of subliminally presented threat-related stimuli than male participants. |
