TL;DR: Direct in vivo evidence of a differential neural response in the human amygdala to facial expressions of fear and happiness is reported, providing direct evidence that the humangdala is engaged in processing the emotional salience of faces, with a specificity of response to fearful facial expressions.

TL;DR: Functional magnetic resonance imaging was used to examine the neural substrate for perceiving disgust expressions and found the neural response to facial expressions of disgust in others is thus closely related to appraisal of distasteful stimuli.

TL;DR: The results of asking subjects to choose the most attractive faces from continua that enhanced or diminished differences between the average shape of female and male faces indicate a selection pressure that limits sexual dimorphism and encourages neoteny in humans.

TL;DR: For example, this article found that increasing symmetry of face shape increases ratings of attractiveness for both male and female faces, which suggests facial symmetry may have a positive impact on mate selection in humans.

TL;DR: Four experiments investigating the perception of photographic quality continua of interpolated ('morphed') facial expressions derived from prototypes of the 6 emotions in the Ekman and Friesen series suggest that rapid classification of prototypes and better across boundary discriminability reflect the underlying organisation of human categorisation abilities.
