一个重要的问题是，金钱奖励是否能增加注意力，从而提高表现。到目前为止，给出肯定答案的证据还很薄弱。因此，在本研究中，我们使用侧卫任务来进一步检验这个问题。在一个侧边任务中，参与者必须在规定的截止日期之前做出反应。一组参与者获得了与表现相关的金钱奖励，而另一组则获得了固定数额的钱。结果，与对照组相比，金钱奖励显著提高了他们的表现。对速度-准确性权衡函数的分析表明，金钱奖励增加了注意力努力，从而提高了刺激编码的质量。几乎没有证据表明，奖励也能提高选择性空间注意力。
An important question is whether monetary reward can increase attentional effort in order to improve performance. Up to now, evidence for a positive answer is weak. Therefore, in the present study, the flanker task was used to examine this question further. Participants had to respond sooner than a certain deadline in a flanker task. One group of participants received a performance-contingent monetary reward, whereas the other group earned a fixed amount of money. As a result, monetary reward significantly improved performance in comparison with the control group. The analysis of speed-accuracy trade-off functions revealed that monetary reward increased attentional effort, leading to an enhanced quality of stimulus coding. Little evidence was found that reward also improved selective spatial attention.
