Background: We systematically reviewed the literature to determine the influence of sex hormones on facial emotion processing FEP in healthy women at different phases of life. Results: Despite the limited number of studies in some categories and the existence of inconsistencies in the results of interest, the findings of the review suggest that FEP may be enhanced during the follicular phase. Studies with women taking oral contraceptives showed reduced recognition accuracy and decreased responsiveness of different brain structures during FEP tasks. Studies with pregnant women and women in the postpartum showed that hormonal changes are associated with alterations in FEP and in brain functioning that could indicate the existence of a hypervigilant state in new and future mothers.

Everybody Who's Had Sex With A Penis Will Recognize These 14 Facial Expressions

There has been much research on sex differences in the ability to recognise facial expressions of emotions, with results generally showing a female advantage in reading emotional expressions from the face. Therefore, little is known about how expression intensity and dynamic stimuli might affect the commonly reported female advantage in facial emotion recognition. Overall, females showed more accurate facial emotion recognition compared to males and were faster in correctly recognising facial emotions. The female advantage in reading expressions from the faces of others was unaffected by expression intensity levels and emotion categories used in the study. The effects were specific to recognition of emotions, as males and females did not differ in the recognition of neutral faces. Together, the results showed a robust sex difference favouring females in facial emotion recognition using video stimuli of a wide range of emotions and expression intensity variations. Facial expressions are an important means of communication [ 1 ], as they can carry inter-personal information, enabling promotion of bonding as well as the development and regulation of interpersonal relationships [ 2 ].

There exists a stereotype that women are more expressive than men; however, research has almost exclusively focused on a single facial behavior, smiling. A large-scale study examines whether women are consistently more expressive than men or whether the effects are dependent on the emotion expressed. Studies of gender differences in expressivity have been somewhat restricted to data collected in lab settings or which required labor-intensive manual coding. In the present study, we analyze gender differences in facial behaviors as over 2, viewers watch a set of video advertisements in their home environments. Using a new automated facial coding technology we coded facial activity.
Seventy right-handed subjects 35 males and 35 females were shown lateralized pictures of negative, neutral, and positive facial emotional expressions. For each emotional category, half of the pictures were of a male face showing the emotion, half were of a female face. The pictures were shown in the left visual half-field for half of the trials and in the right half-field for the other half of the trials.
