先前的理论预测，人类背侧前扣带回（dACC）应该对决策困难做出反应。最近提出了另一种理论，认为dACC的进化代表了“非默认”的觅食行为的价值，质疑其在选择困难中的作用。然而，这一新理论没有考虑到，选择是否追求觅食行为也可能比简单地诉诸“默认”更困难。两个神经影像学实验的结果表明，dACC只与觅食值时，觅食值与选择困难混淆;当两者分离，dACC的参与只能解释选择困难，而不是觅食的价值。除了反驳这一新理论之外，我们的研究还有助于正式确定选择困难和觅食类决策之间的基本联系，同时也为基于奖励的决策研究中的一个常见陷阱提供了解决方案。
Previous theories predict that human dorsal anterior cingulate (dACC) should respond to decision difficulty. An alternative theory has been recently advanced which proposes that dACC evolved to represent the value of “non-default,” foraging behavior, calling into question its role in choice difficulty. However, this new theory does not take into account that choosing whether or not to pursue foraging-like behavior can also be more difficult than simply resorting to a “default.” The results of two neuroimaging experiments show that dACC is only associated with foraging value when foraging value is confounded with choice difficulty; when the two are dissociated, dACC engagement is only explained by choice difficulty, and not the value of foraging. In addition to refuting this new theory, our studies help to formalize a fundamental connection between choice difficulty and foraging-like decisions, while also prescribing a solution for a common pitfall in studies of reward-based decision making.
