Extinction of conditioned responding: Learning from the evidence of absence

当动物或人知道一个线索或他们自己的行动后面有一些重要的东西时，他们会做出反应，预期结果或控制结果。这个项目研究了当建立这些反应的条件发生变化时，这些习得的反应是如何减少（“消失”）的。这将有助于解决两个突出的理论和实践问题：是什么使一些习得行为在消失后不易消失或容易复发？该项目将确定对耐药性和复发最直接负责的因素。这可能为寻找解决方案铺平道路，这些主要问题困扰着治疗人类行为障碍的疗法，如成瘾、赌博和焦虑

When animals or people learn that a cue, or their own action, is followed by something important, they respond in anticipation of the outcome or to control it. This project investigates how these learned responses can be reduced (“extinguished”) when the conditions that established them change. It will help solve 2 outstanding theoretical and practical problems: what makes some learned behaviours resistant to extinction or prone to relapse after being extinguished? The project will identify the factors that are most directly responsible for resistance and relapse. This could pave the way to finding solutions for the major problems that bedevil therapies designed to treat human behavioural disorders, such as addictions, gambling, and anxiety
