Appraisal theory, however, has often been critiqued for failing to capture the dynamic nature of emotion. To better analyze the complexities of emotional appraisal, social psychologists have sought to further complement the structural model. One suggested approach was a cyclical process, which moves from appraisal to coping, and then reappraisal, attempting to capture a more long-term theory of emotional responses (Smith & Lazarus 1990). This model, however, failed to hold up under scholarly and scientific critique, largely due to the fact that it fails to account for the often rapid or automatic nature of emotional responses (Marsella & Gratch 2009). Further addressing the concerns raised with structural and cyclical models of appraisal, two different theories emerged that advocated a process model of appraisal.
