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

当动物或人得知某个暗示或他们自己的行动之后会发生一些重要的事情时，他们会做出反应以预期结果或控制结果。该项目研究了当形成这些反应的条件发生变化时，如何减少（“消除”）这些习得的反应。它将有助于解决两个突出的理论和实践问题：是什么使得一些习得行为难以消退或在消退后容易复发？该项目将确定最直接导致耐药性和复发的因素。这可能为寻找解决方案铺平道路，这些问题困扰着旨在治疗人类行为障碍的疗法，例如成瘾、赌博和焦虑
