Intimate relationships regulate female brain activity in a competitive context: evidence from EEG and functional...

Area of Science:

• Neuroscience
• Social Psychology
• Cognitive Science

Background:

• Intimate relationships are vital for well-being.
• Understanding the influence of relationships on competitive behavior is crucial for social adaptation.
• Female competition dynamics require further investigation, particularly concerning relationship status and competitor characteristics.

Purpose of the Study:

• To investigate the impact of partner presence on female competitive behavior.
• To examine how competitor gender influences female competition.
• To analyze electroencephalography (EEG) correlates of female competition under different relational and social contexts.

Main Methods:

• Electroencephalography (EEG) was employed to record brain activity during competitive tasks.
• Analysis included reaction time differences (DRT), N2 posterior contralateral component (N2pc), and Late Positive Potential (LPP).
• Brainwave frequency bands (alpha and theta) and functional connectivity were assessed.

Main Results:

• Partner absence correlated with smaller DRT, suggesting increased engagement.
• Greater N2pc and LPP amplitudes, alongside enhanced alpha and theta band activity, were observed when partners were absent.
• Competition against same-gender rivals led to higher win rates and N2pc amplitudes.
• Negative correlation found between DRT and N2pc/LPP amplitudes.

Conclusions:

• Partner presence modulates female competitive engagement and performance.
• Decision-making in competition is enhanced when facing same-gender opponents.
• Findings highlight the significant role of intimate relationships in shaping female competitive strategies and social interactions.
