在辨别任务中发生的注意抑制会导致对干扰刺激的负面评价。这种现象，被称为分心物贬值效应，也发生在去/不去任务需要反应抑制时。然而，目前还不清楚是否有注意和反应控制之间的相互作用时，分心物贬值效应发生。本研究的目的是调查在去/不去任务的刺激注意是否起着促进作用，通过反应抑制分心贬值，并澄清这种效果是否反映了不去刺激的偏好下降。参与者评估了在进行/不进行任务之前和之后对图片的偏好。在实验1和2中，他们根据所显示的图片类别（软糖或米饼）做出去或不去的反应，而在实验3中，他们根据叠加在这些图片上的数字类别（偶数或奇数）做出反应。实验1和实验2表明，在前一个go/no-go任务中作为no-go刺激呈现的图片被评价为不如作为go刺激呈现的图片积极。这种贬值效应反映了对去刺激的偏好增加，而不是对不去刺激的偏好减少。实验3表明，反应抑制并不影响偏好的图片，没有得到注意，在前面的去/不去任务。这些结果表明，虽然注意力在对围棋和不围棋刺激的不同评级中起着重要作用，但这种差异实际上反映了对围棋刺激的评价。
Attentional inhibition that occurs during discrimination tasks leads to the negative evaluation of distractor stimuli. This phenomenon, known as the distractor devaluation effect also occurs when go/no-go tasks require response inhibition. However, it remains unclear whether there are interactions between attention and response controls when the distractor devaluation effect occurs. The aims of this study were to investigate whether attention to stimuli in the go/no-go task plays a facilitative role in distractor devaluation through response inhibition, and to clarify whether this effect reflects a decreased preference for no-go stimuli. Participants evaluated the preference for pictures before and after a go/no-go task. In Experiments 1 and 2, they made a go or no-go response depending on the category of pictures displayed (gummy candies or rice crackers), whereas in Experiment 3 they did on the basis digit category, even or odd numbers, superimposed on such pictures. Experiments 1 and 2 demonstrated that the pictures presented as no-go stimuli in the preceding go/no-go task were evaluated as less positive than the pictures presented as go stimuli. This devaluation effect reflected an increased preference for the go stimuli but not a decreased preference for the no-go stimuli. Experiment 3 indicated that response inhibition did not affect the preference for the pictures that had not received attention in a preceding go/no-go task. These results suggest that although attention plays an important role in differential ratings for go and no-go stimuli, such differences, in fact, reflect the valuation of go stimuli.
