Our research has been concerned with the general area of Pavlovian conditioning, especially the contribution of such conditioning to physiological and behavioural regulation. Recently, we have been applying conditioning concepts to the understanding of the judgment of contingent relationships.  In this research we are attempting to integrate  associative and signal detection approaches.
