Humans and other animals readily learn to perform an action if it is “reinforced” by a reward and will extinguish the action if it stops being reinforced. Popular models of learning describe extinction as the automatic outcome of a prediction-error correction process that gradually weakens, and eventually eliminates, the response-reward association. But there is much evidence that conditioned responses are not eliminated and can be quickly restored. Other evidence suggests that extinction might involve more specific inhibitory processes that suppress the response without eliminating the original learning. The current project investigates the role of response inhibition in the extinction of learned responses in humans.

人类和其他动物很容易学会执行一个动作，如果它被奖励“强化”，如果它停止被强化，就会熄灭。流行的学习模型将灭绝描述为预测错误纠正过程的自动结果，该过程逐渐削弱并最终消除反应-奖励关联。但有很多证据表明，条件反射不会被消除，而且可以很快恢复。其他证据表明，灭绝可能涉及更具体的抑制过程，抑制反应而不消除原始学习。目前的项目研究反应抑制在人类习得反应消退中的作用。
