Document Summary
Pareidolia: the ability to recognize faces in inanimate objects. Humans are sensitive to subtle changes in the face estrogen levels indicate ability to reproduce and this basically is an indicator of attractiveness. Even infants rate the same face to be attractive. It is important because face processing gives an insight onto the emotional wellbeing of a person. Judging the quality of what a person is saying is linked with facial expressions: 90 % of liars will show fear or disgust. Holistic face processing: the hollow face illusion. The hollow-face illusion has been used to study the dissociation between vision-for-perception and vision-for-action (see two-streams hypothesis). This result suggests that the bottom-up cues that drive the flicking response are distinct from the top-down cues that drive the hollow-face illusion. Two main hypotheses of facial processing: featural: all the stimuli are broken down and then assembled in the v1 cortex, configural: you use the entire image of a face to process faces.
