Many studies have revealed that reward-associated features capture attention. Neurophysiological evidence further suggests that this reward-driven attention effect modulates visual processes by enhancing low-level visual salience. However, no behavioral study to date has directly examined whether reward-driven attention changes how people see. Combining the two-phase paradigm with a psychophysical method, the current study found that compared with nonsalient cues associated with lower reward, the nonsalient cues associated with higher reward captured more attention, and increased the perceived contrast of the subsequent stimuli. This is the first direct behavioral evidence of the effect of reward-driven attention on low-level visual perception.
许多研究表明，与奖励相关的特征会吸引注意力。神经生理学证据进一步表明，这种受奖励驱动的注意力效应通过增强低水平视觉显著性来调节视觉过程。然而，迄今为止，没有行为研究直接检验奖励驱动的注意力是否会改变人们的视觉感知。本研究结合两阶段范式和心理物理学方法发现，与与较低奖励相关的非显著线索相比，与较高奖励相关的非显著线索吸引了更多的注意力，并增加了后续刺激的感知对比度。这是关于奖励驱动的注意力对低水平视觉感知影响的第一个直接行为证据。
