Neuropsychological processes in emotion and emotional disorders
My research investigates the role of the brain in emotion, including the neuropsychological processes involved in emotional information processing, normal and abnormal emotional states (particularly anxiety and depression), the development of personality and psychopathology, and the interaction of emotional processes with cognition. I have been testing and extending my neuropsychological model of emotion, which has led to specific predictions about regional brain activity during depression and anxiety. Depression has been associated with smaller left hemispatial biases, suggesting .educed right hemisphere activity. In contrast, anxiety has been associated with larger left hemispatial biases, suggesting increased right hemisphere activity. These effects typically emerge only when the variance associated with depression is removed from anxiety, and vice versa. Thus, it is crucial to separate depression and anxiety either statistically or via experimental design in efforts to examine brain function in emotional experience. Another research area involves implications of brain function for cognition in depression and anxiety. An important contribution of our understanding of regional brain activity in these disorders is insight into cognitive capabilities and styles of depressed and anxious people. Activity in regions of the cortex specialized for particular modes of information processing covaries with performance on tasks that benefit from that type of computation.
