The establishment of an accurate understanding of one's social context is a central developmental task during adolescence. A critical component of such development is to learn how to integrate the objective evaluation of one's behavior with the social response to the latter--here referred to as social feedback processing.
We measured brain activity by means of fMRI in 33 healthy adolescents (12-19 years old, 14 females). Participants played a difficult perceptual game with integrated verbal and visual feedback. Verbal feedback provided the participants with objective performance evaluation (won vs. lost). Visual feedback consisted of either smiling or angry faces, representing positive or negative social evaluations. Together, the combination of verbal and visual feedback gave rise to congruent versus incongruent social feedback combinations. In addition to assessing sex differences, we further tested for the effects of age and attachment style on social feedback processing. Results revealed that brain activity during social feedback processing was significantly modulated by sex, age, and attachment style in prefrontal cortical areas, ventral anterior cingulate cortex, anterior insula, caudate, and amygdala/hippocampus. We found indication for heightened activity during incongruent social feedback processing in females, older participants, and individuals with an anxious attachment style. Conversely, we observed stronger activity during processing of congruent social feedback in males and participants with an avoidant attachment style.
Our findings not only extend knowledge on the typical development of socio-emotional brain function during adolescence, but also provide first clues on how attachment insecurities, and particularly attachment avoidance, could interfere with the latter mechanisms.
准确理解自身的社会环境是青少年时期一项核心的发展任务。这种发展的一个关键组成部分是学习如何将对自身行为的客观评价与社会对该行为的反应整合起来——这里称为社会反馈处理。
我们通过功能磁共振成像(fMRI)测量了33名健康青少年(12 - 19岁,14名女性)的大脑活动。参与者进行了一场带有综合言语和视觉反馈的困难感知游戏。言语反馈为参与者提供客观的表现评估(赢与输)。视觉反馈由微笑或愤怒的面孔组成,分别代表积极或消极的社会评价。言语和视觉反馈的组合共同产生了一致与不一致的社会反馈组合。除了评估性别差异外,我们还进一步测试了年龄和依恋风格对社会反馈处理的影响。结果显示,在前额叶皮质区域、腹侧前扣带回皮质、前脑岛、尾状核以及杏仁核/海马体中,社会反馈处理过程中的大脑活动受到性别、年龄和依恋风格的显著调节。我们发现,在不一致的社会反馈处理过程中,女性、年龄较大的参与者以及具有焦虑依恋风格的个体大脑活动增强。相反,我们观察到男性和具有回避型依恋风格的参与者在处理一致的社会反馈时大脑活动更强。
我们的研究结果不仅扩展了对青少年时期社会情感脑功能典型发展的认识,还为依恋不安全感,尤其是依恋回避如何干扰后者机制提供了初步线索。
