Abstract
Affective illness has been associated with lateralized right hemisphere deficits and
global cognitive dysfunction. However, there has been very little exploration of informationprocessing
strategies that may underlie cognitive changes in this population. Twenty euthymic,
drug-free, bipolar patients and 20 controls were given a series of tasks to assess
lateralized impairment of the cerebral hemispheres and sequential (analytic) versus
simultaneous (gestalt) information-processing strategies. There were no differences
between patients and controls in tests sensitive to right or left hemisphere impairment
or in total errors on a face recognition task. However, patients tended to rely on
individual facial features for recognition whereas controls were able to synthesize
multiple elements of the faces. Moreover, on a task that required holistic synthesis
of multiple stimulus elements (Street Gestalt Completion Test), patients made significantly
more errors than controls. Implications for information-processing changes in bipolar
affective illness are discussed.
