Initial romantic attraction (IRA) refers to a series of positive reactions (such as feelings of exhilaration and compulsive thinking) toward desirable potential partners, usually at initial or early-stage encounters when no close relationship has yet been established. After decades of effort, the evolutionary value and key characteristics of IRA are well understood. However, the brain mechanisms associated with IRA are unclear. To address this question, we simulated a mate selection platform similar to that of Tinder. When participants assessed their romantic interest in potential partners on the platform, their electroencephalogram (EEG) signals were recorded in real time. The behavioral data demonstrated that IRA to ideal potential partners mainly reflects the dimensions of arousal and domination. The main study finding was that processing of the individual preference faces that resulted in IRA was associated with a decrease in power in the alpha and lower beta bands over the posterior and anterior sensor clusters; this occurred between 870 and 2,000 ms post-stimulus. Key findings regarding event-related potentials (ERPs) sensitive to individual stimuli preferences were replicated. The results support the hypothesis that brain oscillations in the alpha and lower beta range may reflect modulation in cortical activity associated with individual mate preferences.
初始浪漫吸引（IRA）是指对理想潜在伴侣的一系列积极反应（如兴奋感和强制性思维），通常发生在初始或早期阶段的相遇，此时尚未建立密切关系。经过几十年的努力，IRA 的进化价值和关键特征已得到很好的理解。然而，与 IRA 相关的大脑机制尚不清楚。为了解决这个问题，我们模拟了一个类似于 Tinder 的伴侣选择平台。当参与者在平台上评估他们对潜在伴侣的浪漫兴趣时，他们的脑电图（EEG）信号被实时记录。行为数据表明，对理想潜在伴侣的 IRA 主要反映了兴奋和支配的维度。主要研究结果是，导致 IRA 的个体偏好面孔的处理与刺激后 870 到 2000 毫秒之间后、前传感器集群中 alpha 和较低 beta 频段的功率降低有关；这发生在刺激后 870 到 2000 毫秒之间。与个体刺激偏好相关的事件相关电位（ERP）的关键发现得到了复制。结果支持了这样一种假设，即 alpha 和较低 beta 频段的脑振荡可能反映了与个体伴侣偏好相关的皮质活动的调制。
