Do we actively maintain monogamous relationships by force of will, or does monogamy flow automatically? During functional magnetic resonance imaging (fMRI), male participants in a romantic relationship performed the Implicit Association Test (IAT) to evaluate implicit attitudes toward adultery and a go/no-go task to measure prefrontal activity implicated in explicit executive control. Subsequently, they were engaged in a date-rating task in which they rated how much they wanted to date unfamiliar females. We found that the individuals with higher prefrontal activity during go/no-go task could regulate the interest for dates with unattractive females; moreover, the individuals with both a stronger negative attitude toward adultery and higher prefrontal activity could regulate their interest for dates with attractive females, and such individuals tended to maintain longer romantic relationships with a particular partner. These results indicate that regulation of amorous temptation via monogamous relationship is affected by the combination of automatic and reflective processes.
我们是通过意志力积极维持一夫一妻制关系，还是一夫一妻制会自动形成？在功能磁共振成像（fMRI）过程中，处于恋爱关系中的男性参与者进行了内隐联想测验（IAT），以评估对通奸的内隐态度，并进行了一项“是/否”任务，以测量与明确执行控制相关的前额叶活动。随后，他们参与了一项约会评分任务，在该任务中，他们对与陌生女性约会的意愿程度进行评分。我们发现，在“是/否”任务中前额叶活动较高的个体能够调节与缺乏吸引力女性约会的兴趣；此外，对通奸态度更强且前额叶活动较高的个体能够调节与有吸引力女性约会的兴趣，并且这些个体往往与特定伴侣维持更长时间的恋爱关系。这些结果表明，通过一夫一妻制关系对爱情诱惑的调节受到自动和反思过程相结合的影响。
