Cognitive control and social perception both change during adolescence, but little is known of the interaction of these 2 processes. We aimed to characterize developmental changes in brain activity related to the influence of a social stimulus on cognitive control and more specifically on inhibitory control. Children (age 8-11, = 19), adolescents (age 12-17, = 20), and adults (age 24-40, = 19) performed an antisaccade task with either faces or cars as visual stimuli, during functional magnetic resonance brain imaging. We replicate the finding of the engagement of the core oculomotor and face perception brain regions in all age-groups, with increased involvement of frontoparietal oculomotor regions and fusiform face regions with age. The antisaccade-related activity was modulated by stimulus category significantly only in adolescents. This interaction was observed mainly in occipitotemporal regions as well as in supplementary motor cortex and postcentral gyrus. These results indicate a special treatment of social stimuli during adolescence.
认知控制和社会认知在青春期都会发生变化，但这两个过程之间的相互作用却鲜为人知。我们旨在描述与社会刺激对认知控制尤其是抑制控制的影响相关的大脑活动的发育变化。儿童（8至11岁，n = 19）、青少年（12至17岁，n = 20）和成年人（24至40岁，n = 19）在功能性磁共振脑成像期间进行了一项反扫视任务，视觉刺激为面部或汽车。我们重现了在所有年龄组中核心眼动和面部感知脑区参与的发现，随着年龄增长，额顶叶眼动区和梭状面部区的参与度增加。仅在青少年中，反扫视相关活动受刺激类别显著调节。这种相互作用主要在枕颞区以及辅助运动皮层和中央后回中观察到。这些结果表明青春期对社会刺激有特殊处理。
