Our attention is strongly influenced by reward learning. Stimuli previously associated with monetary reward have been shown to automatically capture attention in both behavioral and neurophysiological studies. Stimuli previously associated with positive social feedback similarly capture attention; however, it is unknown whether such social facilitation of attention relies on similar or dissociable neural systems. Here, we used the value-driven attentional capture paradigm in an fMRI study to identify the neural correlates of attention to stimuli previously associated with social reward. The results reveal learning-dependent priority signals in the contralateral visual cortex, posterior parietal cortex, and caudate tail, similar to studies using monetary reward. An additional priority signal was consistently evident in the right middle frontal gyrus (MFG). Our findings support the notion of a common neural mechanism for directing attention on the basis of selection history that generalizes across different types of reward.
我们的注意力受到奖励学习的强烈影响。在行为和神经生理学研究中都表明，先前与金钱奖励相关的刺激会自动吸引注意力。先前与积极的社会反馈相关的刺激同样吸引注意力;然而，尚不清楚这种社会促进注意力是否依赖于相似或可分离的神经系统。在这里，我们使用 fMRI 研究中的价值驱动注意捕获范式，来确定先前与社会奖励相关的刺激的注意力的神经相关性。研究结果揭示了与使用金钱奖励的研究类似的、在对侧视觉皮层、顶后皮质和尾状核中的与学习相关的优先信号。在右侧额中回 (MFG) 中始终可以观察到一个额外的优先信号。我们的研究结果支持了这样一种观点，即基于选择历史引导注意力的共同神经机制可以推广到不同类型的奖励。
