Irrelevant emotional stimuli often capture attention, disrupting ongoing cognitive processes. In two experiments, we examined whether availability of rewards (monetary and non-monetary) can prevent this attentional capture. Participants completed a central letter identification task while attempting to ignore negative, positive, and neutral distractor images that appeared above or below the targets on 25% of trials. Distraction was indexed by slowing on distractor-present trials. Half the participants completed the task with no performance-contingent reward, while the other half earned points for fast and accurate performance. In Experiment 1, points translated into monetary reward, but in Experiment 2, points had no monetary value. In both experiments, reward reduced capture by emotional distractors, showing that even non-monetary reward can aid attentional control. These findings suggest that motivation encourages use of effective cognitive control mechanisms that effectively prevent attentional capture, even when distractors are emotional.
无关的情绪刺激物经常会吸引注意力,从而干扰正在进行的认知过程。在两项实验中,我们研究了奖励(金钱和非金钱)的可用性是否可以防止这种注意力捕获。参与者在完成中央字母识别任务的同时,试图忽略出现在目标上方或下方的负面、正面和中性干扰图像,这些干扰图像出现在 25%的试验中。干扰通过在存在干扰的试验中减速来衡量。一半的参与者在没有绩效相关奖励的情况下完成任务,而另一半参与者因快速准确的表现而获得积分。在实验 1 中,积分转化为金钱奖励,但在实验 2 中,积分没有金钱价值。在这两个实验中,奖励都减少了情绪干扰的捕获,这表明即使是非金钱奖励也可以帮助注意力控制。这些发现表明,动机鼓励使用有效的认知控制机制,即使在干扰是情绪性的情况下,也能有效地防止注意力捕获。
