Emotional disturbances are central to diverse psychopathologies. In this article, we argue that the functions of emotion are comparable for persons with and without psychopathology. However, impairment in one or more components of emotional processing disrupts the achievement of adaptive emotion functions. Adopting a theoretical conceptualisation of emotional processes that stresses activity in centrally mediated approach and withdrawal systems, we discuss the role of emotion in several forms of psychopathology, including major depression, some of the anxiety disorders, psychopathy, and schizophrenia. In doing so, we highlight the nature of emotion disturbance and attendant behavioural and cognitive deficits. Finally, we discuss the merits of this approach for conceptualising emotional disturbance in psychopathology.
