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.
先前与奖励相关的刺激会持续吸引注意力。我们试图通过反转学习程序来消除这种注意力偏向，即高价值颜色会出人意料地改变。在训练过程中，注意力的优先级会向当前的高价值颜色转移，尽管对原始高价值颜色仍然存在残留的偏向。重要的是，在随后的测试阶段，注意力最初更强烈地偏向原始的高价值颜色，与训练结束时明显的注意力优先级相悖。我们的结果表明，基于价值的注意力偏向不会随着新的学习而快速更新，并且滞后于奖励对策略性注意力优先级的重塑。
