Research Interests

My research is concerned with the mechanisms underlying associative learning in humans. In particular, I am interested in the role of attentional processes in discrimination learning and categorisation.

Another line of research is focused on how behaviour comes under the control of contextual stimuli. I approach this questing by exploring an effect called renewal. Renewal refers to the recovery of an extinguished response when there is a change in the context present during the extinction of this response. As an example, take a situation in which a patient suffers from a relapse at home after having successfully completed an exposure-based treatment in a therapeutic setting.
