My Brain Reads Pain in Your Face, Before Knowing Your Gender

摘要: Humans are expert at recognizing facial features whether they variable (emotions) or unchangeable (gender). Because of its huge communicative value, pain might be detected faster in faces than features. Based on this assumption, we aimed to find a presentation time that enables subliminal discrimination expression without permitting gender discrimination. For 80 individuals, compared the needed (50, 100, 150, 200 milliseconds) discriminate masked static among anger and neutral with male from female faces. Whether these discriminations were associated conscious reportability was tested confidence measures 40 other individuals. The results showed that, 100 milliseconds, 75% participants discriminated above chance level, whereas only 20% gender. Moreover, appeared subliminal. This priority over exist because, even if complex stimuli encoding both sensory affective component pain, signal danger. supports evolution theory relating necessity quickly reading aversive emotions ensure survival but also basis altruistic behavior such as help compassion.
