Divergent cognitive costs for online forms of reappraisal and distraction.

The present study was set out to evaluate the cognitive costs of two major emotion regulation strategies under conditions of increased challenge. Previous studies have established that cognitive reappraisal (construing an emotional event in nonemotional terms) has no cognitive costs. However, in all of these studies, reappraisal was initiated at the emotional situation onset, before emotional response tendencies sufficiently evolved. In the present study, the challenge of regulation strategies was increased by initiating strategies online at a late time point in an emotional situation. Applying this procedure revealed for the first time a cognitive cost for reappraisal and also provided double dissociation between reappraisal and another major cognitive emotion regulation strategy--distraction (diverting attention from an emotional situation via producing neutral thoughts). Specifically, late reappraisal, relative to distraction, resulted in an expenditure of self control resources. Late distraction but not reappraisal impaired memory encoding of the emotional situation.
