处于浪漫关系早期阶段的人通常会向他们的伴侣表达强烈而热情的爱。这一观察结果允许我们假设，与处于长期关系中的人相比，处于关系早期阶段的个人需要更少的执行控制来调节对额外配对关系的兴趣，这一点得到了前额叶皮质功能的支持。为了验证这一假设，我们让恋爱中的男性参与者在功能磁共振成像(FMRI)过程中执行一项进行/不进行的任务，这是一项经过充分验证的任务，可以测量与执行控制有关的右腹外侧前额叶皮质(VLPFC)的活动。随后，参与者参与了一项约会评级任务，在这项任务中，他们对自己有多想和不熟悉的女性约会进行评级。我们发现，右侧VLPFC活性较高的个体更好地调节了他们与陌生女性约会的兴趣。重要的是，这种关系只在有长期伴侣的人中发现，而在那些有短期伴侣的人中没有，这表明只有在长期关系中的个人才需要积极地调节对额外伴侣关系的兴趣。我们的发现通过强调VLPFC的作用来扩展先前关于执行控制在维持一夫一妻制关系中的发现，这一角色因恋爱关系的不同而有所不同。
Individuals in the early stages of a romantic relationship generally express intense passionate love toward their partners. This observation allows us to hypothesize that the regulation of interest in extra-pair relationships by executive control, which is supported by the function of the prefrontal cortex, is less required in individuals in the early stages of a relationship than it is in those who are in a long-term relationship. To test this hypothesis, we asked male participants in romantic relationships to perform a go/no-go task during functional magnetic resonance imaging (fMRI), which is a well-validated task that can measure right ventrolateral prefrontal cortex (VLPFC) activity implicated in executive control. Subsequently, the participants engaged in a date-rating task in which they rated how much they wanted to date unfamiliar females. We found that individuals with higher right VLPFC activity better regulated their interest in dates with unfamiliar females. Importantly, this relationship was found only in individuals with long-term partners, but not in those with short-term partners, indicating that the active regulation of interest in extra-pair relationships is required only in individuals in a long-term relationship. Our findings extend previous findings on executive control in the maintenance of monogamous relationships by highlighting the role of the VLPFC, which varies according to the stage of the romantic relationship.
