The project studies how animals learn about statistical relationships between events (for example, between a visual cue and food). Such learning is highly adaptive, but can contribute to maladaptive behaviours like phobias, addictions, and over-eating. A detailed understanding of learning mechanisms is crucial if we are to develop interventions to control these behaviours. In keeping with that goal, this project focuses on learning about negative correlations, as when a cue signals that food will not occur (inhibitory learning) and when a cue that once signalled food now does not (extinction learning). It uses recently developed tools for uncovering the content of learning, and combines experimental and computational analysis of learning algorithms.

该项目研究动物如何学习事件之间的统计关系（例如，视觉提示和食物之间）。这种学习是高度适应性的，但可能导致适应不良的行为，如恐惧症，成瘾和过度饮食。如果我们要制定干预措施来控制这些行为，对学习机制的详细了解至关重要。为了实现这一目标，该项目专注于学习负相关，例如当一个提示信号表明食物不会出现时（抑制学习），以及当一个曾经发出食物信号的提示现在不出现时（灭绝学习）。它使用最近开发的工具来揭示学习的内容，并结合了学习算法的实验和计算分析。
