Abstract

Despite significant advances in cognitive neuroscience, comprehensive models of emotional functioning that include neuro-behavioral mechanisms and individual differences predicting vulnerability or resiliency to emotional challenges are scarce. At the level of brain structure, there has not been clear consensus on what the most appropriate tools and techniques are for investigating individual differences. At the level of brain function, the link between spatial (where) and temporal (when) aspects of the neural correlates of emotional processing remains unclear. Thus, there is a need to develop and capitalize on novel comprehensive approaches for the examination of emotional factors at multiple levels (i.e., brain structure, brain function, behavior, and individual differences), in order to elucidate the mechanisms of emotion-cognition interactions. These issues were investigated in a series of studies using an interdisciplinary multi-method approach involving structural and functional brain imaging (i.e., structural magnetic resonance imaging, MRI; functional MRI; event-related optical signal, EROS; electroencephalography/event-related potential, EEG/ERP), a cognitive task involving emotion-cognition interactions (i.e., the emotional oddball paradigm), and measures of individual differences (i.e., cognitive reappraisal, positive affectivity, optimism). Such a comprehensive approach is essential to elucidate mechanisms of emotional functioning, which will contribute to the development of novel theoretical frameworks and the design of assessment tools and interventions that promote emotional well-being.
