一个新兴的理论框架表明，与刻板印象和偏见有关的神经功能与额叶网络有关。使用一种新的神经成像技术，功能性近红外光谱（fNIRS），在面对面的现场交流的范例，我们探讨了这个模型的扩展，包括现场动态互动。相似和不同社会经济背景的二人组的神经激活进行比较。每个参与者的社会经济地位是基于教育和收入水平。两组二人组在血流动力学信号采集过程中进行亲社会辩证话语。扫描后的问卷调查证实，增加焦虑和努力的高差距的二人组。与额叶假说相一致，左背外侧前额叶皮层（DLPFC），额极区和三角部更活跃，在语音对话过程中，在高比低视差组。此外，额叶信号在大脑中的同步性更高，而不是低差异的二人组。这些行为，神经影像学和神经耦合研究结果的融合将左额叶过程与“外群体”条件下的自然亲社会对话联系起来，并提出了进一步研究的理论和技术方法。
An emerging theoretical framework suggests that neural functions associated with stereotyping and prejudice are associated with frontal lobe networks. Using a novel neuroimaging technique, functional near-infrared spectroscopy (fNIRS), during a face-to-face live communication paradigm, we explore an extension of this model to include live dynamic interactions. Neural activations were compared for dyads of similar and dissimilar socioeconomic backgrounds. The socioeconomic status of each participant was based on education and income levels. Both groups of dyads engaged in pro-social dialectic discourse during acquisition of hemodynamic signals. Post-scan questionnaires confirmed increased anxiety and effort for high-disparity dyads. Consistent with the frontal lobe hypothesis, left dorsolateral pre-frontal cortex (DLPFC), frontopolar area and pars triangularis were more active during speech dialogue in high than in low-disparity groups. Further, frontal lobe signals were more synchronous across brains for high- than low-disparity dyads. Convergence of these behavioral, neuroimaging and neural coupling findings associate left frontal lobe processes with natural pro-social dialogue under ‘out-group’ conditions and advance both theoretical and technical approaches for further investigation.
