There is general acknowledgement that both the anterior cingulate and orbitofrontal cortex are implicated in reinforcement-guided decision making, and emotion and social behaviour. Despite the interest that these areas generate in both the cognitive neuroscience laboratory and the psychiatric clinic, ideas about the distinctive contributions made by each have only recently begun to emerge. This reflects an increasing understanding of the component processes that underlie reinforcement-guided decision making, such as the representation of reinforcement expectations, the exploration, updating and representation of action values, and the appreciation that choices are guided not just by the prospect of reward but also by the costs that action entails. Evidence is emerging to suggest that the anterior cingulate and orbitofrontal cortex make distinct contributions to each of these aspects of decision making.
人们普遍认为，前扣带回和眶额皮质都与强化引导的决策、情绪和社会行为有关。尽管这些区域在认知神经科学实验室和精神科诊所都引发了兴趣，但关于它们各自独特贡献的观点直到最近才开始出现。这反映出人们对强化引导决策背后的组成过程有了越来越深入的理解，比如强化预期的表征、行动价值的探索、更新和表征，以及认识到选择不仅受奖励前景的引导，还受行动所带来成本的影响。越来越多的证据表明，前扣带回和眶额皮质在决策的这些方面各自做出了独特贡献。
