Previous evidence has shown that after conditioning reward cues may continue to grab attention even when the paired reward is devalued, thus triggering an irrational attentional capture. Here, we investigated whether such persistent cue attentional salience, once established, can be abolished. In Experiment 1, we first confirmed that the cue attentional salience outlasted reward devaluation, and then we found that such persistent capture did not change after an incentive-learning procedure with a devalued reward. In Experiment 2, we showed that the reward cue salience remained unaltered after reward devaluation for at least 1 week. In Experiment 3, we finally succeeded in modifying the cue attentional salience when a new contingency between the cue and the reward was learned, and the reward was not devalued, such that the organism was in a high motivational state. The pattern of results emerging from our study reveals a complex interaction between attention, learning, and motivation, and may help shedding light on the learning mechanisms underlying addiction.

关于奖励的弹性提示注意对奖励贬值、时间、激励学习和应急重新映射的显着性。

先前的证据表明,即使配对奖励被贬值,调节后的奖励线索也可能继续吸引注意力,从而引发非理性的注意力捕获。在这里,我们调查了这种持久的线索注意显着性一旦建立,是否可以消除。在实验 1 中,我们首先确认提示注意显着性比奖励贬值更持久,然后我们发现这种持续捕获在奖励贬值的激励学习程序后没有改变。在实验 2 中,我们表明奖励线索显着性在奖励贬值至少 1 周后保持不变。在实验 3 中,当学习到提示和奖励之间的新偶然性并且奖励没有贬值时,我们终于成功地修改了提示注意显着性,使有机体处于高动机状态。从我们的研究中得出的结果模式揭示了注意力、学习和动机之间复杂的相互作用,并可能有助于阐明成瘾背后的学习机制。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。
