我们测试了青少年在社交脑的结构发展中是否彼此不同，以及社交脑发展中的个体差异是否预示了友谊质量发展的可变性。青少年（N = 299，M_年龄T1 =13.98年），每三年两次。我们分析了在T1和T3与最佳朋友的自我报告的友谊质量，并分析了前额内侧皮层（mPFC），颞上颞沟（pSTS），颞顶交界处（TPJ）和前突神经的表面积和皮质厚度的双边测量所有的浪潮。在组一级，生长曲线模型证实了社交脑区域的表面积和皮质厚度的非线性下降。我们发现社会大脑区域的水平和变化率存在很大的个体差异，尤其是在mPFC，pSTS和TPJ的表面积方面。皮层厚度的变化率在人与人之间变化较小。较高水平的mPFC表面积和皮质厚度预示着友谊质量会随着时间的推移而增强。而且，mPFC表面积的皮层变薄越快，表明友谊质量就越强。较高水平的TPJ皮质厚度预示较低的友谊质量。在一起，我们的结果表明社交大脑发育的异质性，以及这种变异性如何独特地预测友谊质量的发展。

Beyond the average brain: individual differences in social brain development are associated with friendship quality

We tested whether adolescents differ from each other in the structural development of the social brain and whether individual differences in social brain development predicted variability in friendship quality development. Adolescents (N = 299, M_age T1 =13.98 years) were followed across three biannual waves. We analysed self-reported friendship quality with the best friend at T1 and T3, and bilateral measures of surface area and cortical thickness of the medial prefrontal cortex (mPFC), posterior superior temporal sulcus (pSTS), temporoparietal junction (TPJ) and precuneus across all waves. At the group level, growth curve models confirmed non-linear decreases of surface area and cortical thickness in social brain regions. We identified substantial individual differences in levels and change rates of social brain regions, especially for surface area of the mPFC, pSTS and TPJ. Change rates of cortical thickness varied less between persons. Higher levels of mPFC surface area and cortical thickness predicted stronger increases in friendship quality over time. Moreover, faster cortical thinning of mPFC surface area predicted a stronger increase in friendship quality. Higher levels of TPJ cortical thickness predicted lower friendship quality. Together, our results indicate heterogeneity in social brain development and how this variability uniquely predicts friendship quality development.
