先前与奖励相关的刺激持续地吸引注意力。我们试图消除这种注意力偏差,通过逆向学习过程中,高价值的颜色发生了意外的变化。在训练过程中,注意力的优先级发生了变化,有利于当前的高值颜色,尽管对原始高值颜色的残余偏见仍然很明显。重要的是,在随后的测试阶段,注意力最初更强烈地偏向于最初的高价值颜色,这与训练结束时明显的注意力优先顺序相反。我们的研究结果表明,基于价值的注意偏向不会随着新的学习而迅速更新,并且滞后于奖励对战略注意优先级的重塑。
Previously reward-associated stimuli persistently capture attention. We attempted to extinguish this attentional bias through a reversal learning procedure where the high-value color changed unexpectedly. Attentional priority shifted during training in favor of the currently high-value color, although a residual bias toward the original high-value color was still evident. Importantly, during a subsequent test phase, attention was initially more strongly biased toward the original high-value color, counter to the attentional priorities evident at the end of training. Our results show that value-based attentional biases do not quickly update with new learning and lag behind the reshaping of strategic attentional priorities by reward.
