Emotional attention: Time course and effects of agonistic and antagonistic overlay of intrinsic and goal relevances.
Résumé
Emotional attention can be explained within a goal-directed theory framework according to which attention is captured by the goal relevance of stimuli, that is, their conduciveness nature to a momentarily important goal. However, such an explanation does not consider the attentional impact of intrinsic relevance of stimuli, that is, their general pleasantness. This problem could be resolved by appraisal theories, suggesting that attention is captured by intrinsic relevance and goal relevance of stimuli, whether the relevance overlay is agonistic (e.g., pleasant and goal-conducive) or antagonistic (e.g., unpleasant and goal-conducive). Moreover, appraisal theories suggest that early and late attentional capture would be more impacted by intrinsic relevance and goal relevance, respectively. In the present study, we confronted the predictions of appraisal theories with that of goal-directed theory. To this end, 120 participants performed parallelly an induction task to induce different relevance values to three colored squares, and a dot-probe task with two different stimulus onset asynchrony, to measure early and late attentional captures. This paradigm allowed us to measure attentional capture between a neutral stimulus, a goal-relevant stimulus, and an overlay stimulus. The overlay stimulus was agonistic in one group, while it was antagonistic in the other group. Our results showed evidence in favor of appraisal theories. Namely, the overlay stimulus captured more attention than the goal-relevant and the neutral stimulus, regardless of whether the overlay was agonistic or antagonistic. However, our results were mixed regarding the effects of intrinsic relevance and goal relevance on attentional capture as a function of temporality.
