He characterizes automatic processes (in various areas of research), and clarifies their importance, the relationship between automatic and voluntary processes, and their neural underpinnings. Most of his work involves research with human participants and in recent years, he has been working with Archer fish in order to examine evolutionary aspects of various cognitive functions.
