Exploring the Contribution of Gender Roles on Adults' EEG Responses to Infant Faces

Area of Science:

• Cognitive Neuroscience
• Social Psychology
• Developmental Psychology

Background:

• Previous research indicates women are generally more responsive to infant cues than men.
• The impact of specific gender roles (femininity, masculinity) on infant cue processing remains unexplored.
• Understanding social gender's influence is crucial for infant care and development research.

Purpose of the Study:

• To investigate the association between gender roles (femininity, masculinity) and electrophysiological responses to infant and adult facial stimuli.
• To determine if continuous traits of femininity and masculinity predict neural sensitivity to infant cues.
• To explore the role of sociocultural gender norms in early-stage infant face perception.

Main Methods:

• Utilized electroencephalography (EEG) to record neural activity in 60 non-parent adults.
• Participants completed an emotion recognition task with infant and adult faces (happy, neutral, sad).
• Assessed levels of femininity and masculinity using an Italian translation of the Bem Sex Role Inventory.

Main Results:

• Higher levels of femininity were significantly associated with a larger N170 amplitude in response to infant faces.
• This suggests enhanced perceptual processing of infant faces at an early neural stage for individuals high in femininity.
• No significant associations were found for masculinity levels.

Conclusions:

• Sociocultural norms associated with femininity contribute to enhanced processing of infant facial cues.
• Electrophysiological responses to infant cues are influenced by gender roles, extending beyond biological sex.
• Future research should incorporate nuanced aspects of social gender in studies of infant cue processing.
