Abstract |
Sequential effects in conflict processing (postconflict slowing and conflict adaptation) have primarily been studied in stimulus-response compatibility (SRC) tasks. Moreover, results obtained in SRC paradigms are often proposed as a model of higher-level motivational conflicts. The authors present 3 experiments suggesting that motivational conflicts, such as approach-approach (AA) and avoidance-avoidance (VV) conflicts partially engage different processes than SRC conflicts and thus result in different sequential effects. Instead of postconflict slowing, they predicted speeding after AA conflicts because they expect the approach motivation component of AA conflicts to briefly increase action readiness. Second, the authors expected larger conflict adaptation in VV than AA conflicts because conflict adaptation is known to be enhanced by inducing negative affect. They conducted 3 experiments with varying intertrial intervals (intertrial interval [ITI]) in which participants repeatedly solved hypothetical motivational conflicts (AA, VV) and nonconflicts (NC). In all three experiments, the authors observed postconflict speeding after AA conflicts compared to NC when the ITI was short. Conflict adaptation proved to be less reliable. These results extend previous research on sequential effects in conflict resolution by showing that sequential effects emerge also in higher-level motivational AA and VV conflicts but partially follow different rules than in SRC paradigms.
