Abstract：
Competition is common in life, and intimate relationships are essential. Understanding how intimate relationships impact an individual\'s competitive process is crucial. This study explored the impact of competitor gender on female competition using electroencephalography analysis. The results revealed that females exhibited a smaller median of the absolute value of reaction time difference (DRT) between their partners and their competitors when their partners were absent compared to when their partners were present. Additionally, females showed greater average amplitudes of N2 posterior contralateral component (N2pc) and Late Positive Potential (LPP), increased activation of the alpha frequency band, and enhanced theta frequency band functional connectivity between the central parietal lobe and occipital lobe. Furthermore, when competing with individuals of the same gender as opposed to individuals of the opposite gender, females exhibited greater average amplitudes of percentage of wins and N2pc. A significant negative correlation was noted between the DRT and the average wave amplitudes of N2pc and LPP. These findings suggest that females are more engaged in competitive tasks when partners are not present and have improved decision-making when competing with same-gender individuals. This study provides evidence for the influence of lovers on female competition, helping females adapt to social competition and promoting healthy relationships.
摘要：
竞争在生活中很常见，亲密关系是必不可少的。了解亲密关系如何影响个人的竞争过程是至关重要的。本研究使用脑电图分析探讨了竞争对手性别对女性竞争的影响。结果表明，与伴侣不在时相比，女性在伴侣与竞争对手之间的反应时间差（DRT）的绝对值中位数较小。此外,女性表现出更大的N2后对侧分量（N2pc）和晚期正电位（LPP）的平均振幅，alpha频段的激活增加，增强了中央顶叶和枕叶之间的theta频带功能连通性。此外，当与同性别的个人而不是异性的个人竞争时，女性表现出更大的获胜率和N2pc的平均幅度。DRT与N2pc和LPP的平均波幅之间存在显着负相关。这些发现表明，当伴侣不在场时，女性会更多地参与竞争性任务，并且在与同性别个体竞争时改善了决策。这项研究为恋人对女性竞争的影响提供了证据，帮助女性适应社会竞争，促进健康的人际关系。
