Perceived conflict may be negative but resolved conflict is not

Abstract

The current study investigated how exposure to a conflict stimulus influences the judgment of a subsequent stimulus's valence. We used an affective priming paradigm, presenting a color Stroop stimulus as a prime and a face as a target for an emotion recognition task. When the task for the prime was passive viewing (Experiment 1), congruent primes resulted in faster responses to emotionally positive targets than negative targets. However, this positivity bias disappeared following incongruent primes. In Experiment 2, instead of passive viewing, participants were asked to indicate the congruency of the prime, and the positivity bias was significant following the congruent prime but not following the incongruent prime. In Experiments 3 and 4, participants performed the conventional Stroop task on the prime, therefore resolving the conflict when the prime was incongruent. Experiment 3 adopted an equal proportion of congruent and incongruent primes. Experiment 4 adopted twice as many congruent primes as incongruent primes. In both experiments, the positivity bias was not significant regardless of the congruency of the prime. These results suggest that detecting conflict may interfere with positive affect or promote negative affect, therefore reducing the positivity bias. Once the conflict is resolved, however, the negative valence may disappear.
