现实世界的决策只有在以后才能带来好处，并且取决于在过渡期间做出的其他决策。我们在一项新的人类决策任务中研究了这一点（n = 76），同时用fMRI测量大脑活动（n = 24）。模型显示，参与者计算决策的预期价值：他们计划他们未来的行为，考虑到他们的决策可能会影响他们将遇到的状态，以及他们自己在这些状态下可能会做出的反应。他们考虑了自己未来可能的行为偏见（例如，未能适应预期价值的变化），并避免了他们可能倾向于这种偏见的情况。相邻内侧额叶区域的三个神经网络与前瞻性决策的不同组成部分有关：背侧前扣带皮层（面积8 m/9）和膝周前扣带皮层的活动反映了前瞻性价值、前瞻性价值的预期变化以及前瞻性价值影响决策的程度。人们在做出顺序选择时使用关于未来状态的前瞻性信息人们洞察到他们的未来偏见并先发制人地避免关键情况不同的扣带-前额叶相互作用编码前瞻性和近视价值周膝扣带激发了顺序行为中的坚持。研究了扩展的顺序决策问题。参与者使用前瞻性信息，甚至提前几步为最初的决策规划提供信息。背侧扣带回活动表明了预期的价值，而膝周扣带回活动则促进了决策序列的表现。
Real-world decisions have benefits occurring only later and dependent on additional decisions taken in the interim. We investigated this in a novel decision-making task in humans (n = 76) while measuring brain activity with fMRI (n = 24). Modeling revealed that participants computed the prospective value of decisions: they planned their future behavior taking into account how their decisions might affect which states they would encounter and how they themselves might respond in these states. They considered their own likely future behavioral biases (e.g., failure to adapt to changes in prospective value) and avoided situations in which they might be prone to such biases. Three neural networks in adjacent medial frontal regions were linked to distinct components of prospective decision making: activity in dorsal anterior cingulate cortex, area 8 m/9, and perigenual anterior cingulate cortex reflected prospective value, anticipated changes in prospective value, and the degree to which prospective value influenced decisions. People use prospective information about future state when making sequential choices People have insight into their future biases and pre-emptively avoid key situations Distinct cingulate-prefrontal interactions encode prospective and myopic value Perigenual cingulate motivates perseveration in sequential behavior Kolling and Scholl et al. examined extended sequential decision-making problems. Participants used prospective information to inform even initial decision planning several steps ahead. Dorsal cingulate activity signaled prospective value while perigenual cingulate activity motivated decision sequence performance.
