In order to comprehensively understand the anxiety disorders, multiple viewpoints must be taken into account. These vantage points include cognitive neuroscience, neuroimaging, learning theory, and genetics, among others. With the major technological developments taking place today, our appreciation of the neurobiological basis of normal and pathological anxiety is advancing rapidly. In order to help to place these findings in context, sophisticated psychological paradigms and techniques must also be used and developed. With this integration of the psychological and neurobiological approaches, our clinical techniques applied to these disabling disorders may be perfected in a rigorous, empirically based manner.
