The performance of agoraphobic and normal subjects is compared across three different types of task (Kamin blocking effect, incidental learning, and choice reaction time) all designed to tap processing of neutral stimuli. Agoraphobics differed from normals on the Kamin blocking task and on one of the two incidental learning measures employed. Choice reaction time performance was the same in both groups. The relevance of these findings for future studies of emotional processing in such subjects is discussed.
